NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.      Basis of Presentation

These unaudited interim Consolidated Financial Statements of Sun Communities, Inc., a Maryland corporation, and all wholly-owned or majority-owned  and controlled subsidiaries, including Sun Communities Operating Limited Partnership (the “Operating Partnership”), SunChamp LLC (“SunChamp”), and Sun Home Services, Inc. (“SHS”), have been prepared pursuant to the Securities and Exchange Commission (“SEC”) rules and regulations and in accordance with accounting principles generally accepted in the United States of America (“GAAP”).  Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Consolidated Financial Statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2011 as filed with the SEC on February 24, 2012, as amended on March 23, 2012 (the “2011 Annual Report”).

Reference in this report to Sun Communities, Inc., “we”, “our”, “us” and the “Company” refer to Sun Communities, Inc. and its subsidiaries, unless the context indicates otherwise.

The accompanying Consolidated Financial Statements reflect, in the opinion of management, all adjustments necessary for a fair presentation of the interim financial statements. All such adjustments are of a normal and recurring nature.

The following Notes to Consolidated Financial Statements present interim disclosures as required by the SEC. These statements have been prepared on a basis that is substantially consistent with the accounting principles applied in our 2011 Annual Report.

Certain reclassifications have been made to prior periods’ financial statements in order to conform to current period presentation.

2.      Real Estate Acquisitions

In May 2011, we acquired Orange City RV Resort (“Orange City”), a Florida recreational vehicle community comprising 525 developed sites.  In June 2011, we closed on the acquisition of Kentland Communities (“Kentland”), comprising 17 manufactured home communities and one recreational vehicle community.  The 18 communities acquired are located in western Michigan and comprise 5,434 developed sites.  In November 2011, we acquired Cider Mill Crossings (“Cider Mill”), a Michigan manufactured home community comprising 262 developed sites through an auction. In December 2011, we acquired three Florida RV communities, Club Naples RV Resort, Kountree RV Resort, and North Lake RV Resort (collectively the “Florida Properties”), two of which are in Naples, Florida and one of which is in Moore Haven, Florida, comprised of 740 developed sites. These acquisitions complement our existing portfolio and create both short-term and long-term growth opportunities.

In February 2012, we acquired three additional Florida RV communities, Three Lakes RV Resort, Blueberry Hill RV Resort and Grand Lake Estates (collectively, the “Additional Florida Properties”), one of which is located in Hudson, Florida, one of which is located in Bushnell, Florida and one of which is located in Orange Lake, Florida, comprised of 1,114 RV sites in the aggregate. We believe this portfolio provides for growth from both rental increases and through improved seasonal occupancy.

On July 24, 2012 we acquired Blazing Star, a recreational vehicle community with 260 sites located in San Antonio, Texas, for a purchase price of $7.1 million, comprised of $4.1 million of assumed debt and $3.0 million of cash.

Acquisition related costs of approximately $0.6 million and $1.4 million have been incurred for the six months ended June 30,2012 and 2011, respectively, and are presented as “Acquisition related costs” in our Consolidated Statements of Operations.

During the third quarter of 2011, we completed the purchase price allocation for Kentland and Orange City. In the first quarter of 2012 some of the amounts previously estimated changed. The changes in estimates included a decrease in other assets of $0.8 million and a decrease in cash consideration of $0.8 million for the Florida Properties. The measurement period adjustments represent updates made to the purchase price allocation based on the escrow amount required for the Additional Florida Properties which is reflected in the purchase price allocation for the Additional Florida Properties. There were no significant adjustments to our Consolidated Statements of Operations.

The purchase price allocation for Cider Mill, the Florida Properties, and the Additional Florida Properties is preliminary and may be adjusted as final costs and final valuations are determined.

⁽¹⁾ Subsequent to the acquisition, on March 30, 2012, the Additional Florida Properties were encumbered with a $19.0 million loan through Bank of America and The PrivateBank (See Note 8).

As of June 30, 2012, the total residual value of the acquired in-place leases above is $8.2 million. The amortization period is 7 years.

The results of operations of Kentland, Orange City, Cider Mill, the Florida Properties, and the Additional Florida Properties are included in the Consolidated Statements of Operations beginning on their acquisition dates of June 2011, May 2011, November 2011, December 2011, and February 2012, respectively. The following unaudited pro forma financial information presents the results of our operations for the six months ended June 30,2012 and 2011 as if the properties were acquired on January 1, 2010 for those communities acquired in 2011 and January 1, 2011 for those that were acquired in 2012. The unaudited pro forma results have been prepared for comparative purposes only and do not purport to be indicative of either the results of operations that would have actually occurred or the future results of operations (in thousands, except per-share data). ⁽¹⁾

⁽¹⁾ Below are nonrecurring expenses that have been adjusted for the pro forma results above:

(a) The sellers had management fees of $0.7 million for the six months ended June 30,2011 that have been excluded from above as these fees will not continue going forward.

(b) Transaction costs related to the acquisitions are not expected to have a continuing impact and therefore have been excluded from 2012 and included in 2011.

See Note 2 for details on recent acquisitions.

4.      Transfers of Financial Assets

We completed various transactions with an unrelated entity involving our notes receivable during 2012 under which we received a total of $11.5 million of cash proceeds in exchange for relinquishing our right, title and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables as a transfer of financial assets. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of note default, and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note.  The percentage used to determine the repurchase price of the outstanding principal balance on the installment note is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase %
Less than or equal to 15	100	%
Greater than 15 but less than 64	90	%
Equal to or greater than 64 but less than 120	65	%
120 or more	50	%

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

The transferred assets have been classified as collateralized receivables in Notes and Other Receivables (see Note 5) and the cash proceeds received from these transactions have been classified as a secured borrowing in Debt (see Note 8) within the Consolidated Balance Sheets. The balance of the collateralized receivables was $86.5 million (net of allowance of $0.5 million ) and $81.2 million (net of allowance of $0.5 million) as of June 30, 2012 and December 31, 2011, respectively.  The outstanding balance on the secured borrowing was $87.1 million and $81.7 million as of June 30, 2012 and December 31, 2011, respectively.

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Six Months Ended			Year Ended
	June 30, 2012			December 31, 2011
Beginning balance	$	81,682		$	71,278
Financed sales of manufactured homes	11,467			21,509

Total activity	5,387			10,404
Ending balance	$	87,069		$	81,682

The collateralized receivables earn interest income and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $4.4 million and $4.0 million for the six months ended June 30,2012 and 2011, respectively.

Collateralized Term Loans

In March, 2011, we completed a collateralized mortgage backed security “CMBS” financing with JPMorgan Chase Bank, National Association for $115.0 million bearing an interest rate of 5.837% and a maturity date of March 1, 2021. This loan is secured by 11 properties. The loan refinanced $104.8 million of CMBS debt which was scheduled to mature in July 2011 and was collateralized using the same property pool.

In May 2011, we completed a refinancing agreement with Bank of America N.A., for $23.6 million. This debt bears an interest rate of 5.38% and has a maturity of June 1, 2021. This loan is secured by three properties. The loan refinanced $17.9 million of debt which was scheduled to mature in June 2012 and was collateralized using the same property pool.

In July 2011, we reached an agreement with Fannie Mae (“FNMA”) and PNC Bank, National Association, regarding the settlement of the litigation we commenced in November 2009 over certain fees charged when the variable rate loan facility was extended in April 2009. The agreement became effective January 3, 2012 and the litigation was dismissed. In accordance with the terms of the agreement, we have the option to extend the maturity date of our entire $367.0 million credit facility with PNC Bank and FNMA from 2014 to 2023, subject to compliance with certain underwriting criteria. This agreement also provided a reduction in the facility fee charged on our variable rate facility for 2011. In addition we drew a $10.0 million variable rate facility, which matures on May 1, 2023 and provides for interest-only payments until May 1, 2014, after which principal and interest payments will be due based on a 30-year amortization.  The interest rate for the $10.0 million variable rate facility is equal to the 90-day LIBOR index, plus an investor spread equal to 95 basis points, plus a variable facility fee equal to 172 basis points through maturity.

The collateralized term loans totaling $1.0 billion as of June 30, 2012, are secured by 96 properties comprised of 35,107 sites representing approximately $574.8 million of net book value.

Aspen preferred OP Units and Series B-3 preferred OP units

The Aspen preferred OP units are convertible into 526,212 common shares based on a conversion price of $68 per share with a redemption date of January 1, 2024. The minimum and maximum annual preferred rate is 6.5 percent and 9.0 percent, respectively. The current preferred rate is 6.5 percent.

We redeemed $1.0 million of Series B-3 preferred OP units in May 2012.

Secured Borrowing

See Note 4 for additional information regarding our collateralized receivables and secured borrowing transactions.

Mortgage Notes

In June 2011, we assumed secured debt with a principal balance of $52.4 million, as a result of the Kentland acquisition (see Note 2 for acquisition details), that had a weighted average maturity of 4.4 years and weighted average annual interest rate of 5.70% at the date of acquisition. This secured debt was recorded at fair value on the date of the acquisition which was equal to the assumed

principal balance. This debt is secured by 12 properties. The current weighted average maturity is 3.9 years with the current weighted average annual variable interest rate of 5.61%.

In June 2011, we entered into a $22.9 million variable financing agreement with Bank of America N.A., to fund the Kentland and Orange City acquisition (see Note 2 for acquisition details). The agreement has a weighted average maturity of 3.7 years and weighted average annual variable interest rate of 3.10% at the date of acquisition. The debt was collateralized by six properties – five Kentland properties and Orange City. On February 1, 2012, we paid off $4.5 million of this agreement which was collateralized by Orange City. The current weighted average maturity is 2.9 years with the current weighted average annual variable interest rate of 3.10%.

In December 2011, we entered into a $17.0 million variable financing agreement with Bank of America, N.A. and The Private Bank to fund the Florida Properties acquisition (see Note 2 for acquisition details). The agreement has a weighted average maturity of 5.0 years and had an effective interest rate of 2.78% at the date of acquisition. The debt was collateralized by all three of the properties acquired in the Florida Properties acquisition. The current weighted average maturity is 4.5 years with the current weighted average annual variable interest rate of 2.75%.

In March 2012, we entered into an amended and restated variable financing agreement with Bank of America, N.A. and The PrivateBank which added an additional $19.0 million to the December 2011 variable financing agreement, the "36.0 Million Facility." The agreement has a weighted average maturity of 4.7 years and had an effective interest rate of 2.74% at the date of acquisition. The debt is collateralized by the three properties acquired in the Additional Florida Properties acquisition.

In March 2012, we paid off the entire $2.7 million mortgage agreement secured by Leisure Village which was due to mature on April 1, 2012.

In June 2012, we completed a variable refinancing agreement with Bank of America N.A., for $14.1 million. This debt bears an interest rate of LIBOR plus a 2.0% margin (effective rate at June 30, 2012 was 2.25%) and has a maturity of September 1, 2016, assuming the election of the two successive one-year extensions. The loan is secured by two properties and refinanced $14.0 million of debt which matured in June 2012.

The mortgage notes totaling $154.0 million as of June 30, 2012, are collateralized by 31 properties comprised of 8,160 sites representing approximately $256.3 million of net book value.

Lines of Credit

In September 2011, we entered into a senior secured revolving credit facility with Bank of America, N.A., and certain other lenders in the amount of $130.0 million (the "Facility"), which replaced our $115.0 million revolving line of credit.  The Facility is secured by a first priority lien on all of our equity interests in each entity that owns all or a portion of the properties constituting the borrowing base and collateral assignments of our senior and mezzanine debt positions in certain borrowing base properties. The Facility has a built-in accordion feature allowing up to $20.0 million in additional borrowings and a one-year extension option, both at our discretion. The Facility matures on October 1, 2015, assuming the election of the extension. The Facility bears interest at a floating rate based on Eurodollar plus a margin that is determined based on our leverage ratio calculated in accordance with the Facility, which can range from 2.25% to 2.95%. Based on our calculation of the leverage ratio as of June 30, 2012, the margin is 2.50% . The outstanding balance on the line of credit was $20.1 million and $107.5 million as of June 30, 2012 and December 31, 2011, respectively. In addition, $4.0 million of availability was used to back standby letters of credit as of June 30, 2012 and December 31, 2011. As of June 30, 2012 and December 31, 2011, $105.9 million and $18.5 million, respectively, were available to be drawn under the facility based on the calculation of the borrowing base at each date.

We have a $20.0 million secured line of credit agreement collateralized by a portion of our rental home portfolio. The net book value of the rental homes pledged as security for the loan must meet or exceed 200 percent of the outstanding loan balance. The terms of the agreement require interest only payments for the first 5 years, with the remainder of the term being amortized based on a 10 year term. The current effective interest rate is Prime plus 200 basis points, or 5.5 percent at June 30, 2012. Prime shall mean the prime rate published in the Wall Street Journal adjusted the first day of each calendar month. The outstanding balance was zero as of June 30, 2012. The outstanding balance was $16.0 million as of December 31, 2011.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us 12 month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of Prime or 6.0 percent (effective

rate 7.0 percent at June 30, 2012).  Prime means the prevailing “prime rate” as quoted in the Wall Street Journal on the first business day of each month. The outstanding balance was $4.5 million and $5.5 million as of June 30, 2012 and December 31, 2011, respectively.

The most restrictive of our debt agreements place limitations on secured borrowings and contain minimum fixed charge coverage, leverage, distribution and net worth requirements. As of June 30, 2012, we were in compliance with all covenants except that our subsidiaries that own the Florida Properties and the Additional Florida Properties were not in compliance with the debt service coverage ratio contained in the $36.0 Million Facility. There is no Event of Default under the $36.0 Million Facility. We have requested a waiver of such covenant for a specified period of time and, if we are unable to obtain such waiver, we intend to comply with this covenant by voluntarily paying down a portion of the $36.0 Million Facility in accordance with the loan agreement.

9.      Equity Transactions

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock.  We have 400,000 common shares remaining in the repurchase program.  No common shares were repurchased during 2012 or 2011.  There is no expiration date specified for the buyback program.

Common OP Unit holders can convert their Common OP units into an equivalent number of shares of common stock at any time.  During the six months ended June 30,2012 and 2011, holders of Common OP Units converted 2,000 and 10,249 units, respectively to common stock.

On May 10, 2012 pursuant to a shelf registration statement on Form S-3, we registered with the SEC the sale of our common stock, preferred stock, debt securities, warrants and units consisting of two or more of the aforementioned securities. This shelf registration statement was effective upon filing and replaced our previous shelf registration statement which was scheduled to expire in May 2012.

On May 10, 2012 we entered into an "at-the-market" sales agreement with BMO Capital Markets Corp and Liquidnet Inc. to issue and sell shares of common stock from time to time. The current authorization allows for the sale of our common stock up to an aggregate amount of $100 million. There were no shares of common stock sold through June 30, 2012.

In January 2012, we closed an underwritten registered public offering of 4,600,000 shares of common stock at a price of $35.50 per share. The net proceeds from the offering were $156.0 million after deducting the underwriting discounts and expenses related to the offering. We used the net proceeds of the offering to repay $123.5 million of outstanding debt and we used $25.0 million to fund a portion of the Additional Florida Properties (See Note 2 for additional information), which were subsequently encumbered with a loan of $19.0 million. We expect to use any remaining net proceeds of the offering to fund possible future acquisitions of properties and for working capital and general corporate purposes.

Under our previous shelf registration statement on Form S-3 we had an "at-the-market" sales agreement to issue and sell shares

of common stock from time to time. We issued 40,524 shares of common stock from January 1, 2012 through May 9, 2012, when the sales agreement was terminated.  The shares of common stock were sold at the prevailing market price of our common stock at the time of each sale with a weighted average sale price of $37.22 and we received net proceeds of approximately $1.5 million.  The proceeds were used to pay down our line of credit.

On August 6, 2010, we entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with REIT Opportunity, Ltd. (“REIT Ltd.”), which provides that, upon the terms and subject to the conditions set forth in the Purchase Agreement, REIT Ltd. is committed to purchase up to the lesser of $100 million of our common stock, or 3,889,493 shares of our common stock, which is equal to one share less than twenty percent of our issued and outstanding shares of common stock on the effective date of the Purchase Agreement.  From time to time over the two year term of the Purchase Agreement, and at our sole discretion, we may present REIT Ltd. with draw down notices to purchase our common stock.  Any and all issuances of shares of common stock

to REIT Ltd. pursuant to the Purchase Agreement will be registered on our effective shelf registration statement on Form S-3.  In January, 2011 we sold 915,827 shares of common stock at a weighted average sale price of $32.76 and received net proceeds of $30.0 million.  The funds were used to pay down our line of credit.

In June 2011, we issued $45.5 million of Series A-1 preferred operating partnership (“A-1 preferred OP”) units as a result of the Kentland acquisition (see Note 2 for details).  A-1 preferred OP unit holders can convert the A-1 preferred OP units into shares of common stock at any time after December 31, 2013 based on a conversion price of $41 per share with $100 par value.  These A-1 preferred OP units are convertible, but not redeemable.  The A-1 preferred OP unit holders receive a preferred return of 5.1% until June 23, 2013 and 6.0% thereafter.

In August 2011, we discovered that we did not register with the SEC shares of our common stock purchased in the open market by our 401(k) plan for the benefit of participants in the plan.  We eliminated the option to purchase our common stock in the plan in September 2011 and the last purchase made through the plan was on September 16, 2011. As disclosed in our prior SEC filings, we considered filing a registration statement on Form S-3 offering to rescind the purchase of shares of our common stock by persons who acquired such shares through our 401(k) plan from September 16, 2010 through September 16, 2011. During that period, the plan purchased a total of 3,301 shares of our common stock for the benefit of a total of 85 participants. If a rescission offer were conducted, we would offer to repurchase shares of our common stock purchased through the 401(k) plan during the one year period ended September 16, 2011, but only if such shares either (i) were subsequently sold at a loss, or (ii) were purchased at a price higher than the market price of our common stock at the end of the rescission offer period, and are still held by the plan participant. To the best of our knowledge no shares purchased during the applicable period have subsequently been sold at a loss. Based on the recent and current market price of our common stock, we believe our potential liability, if any, with respect to shares of our common stock purchased during the applicable period and still held by plan participants is not material to us. In fact, if we were to conduct a rescission offer today, we do not believe we would have any liability unless the market price of our common stock at the end of the rescission offer period were less than $39.28 per share, which is the highest price paid for purchases of shares by plan participants during the applicable period. Based on these facts and given the expense of conducting a rescission offer, we have determined not to conduct a rescission offer.

Cash dividends of $0.63 per share were declared for the quarter ended June 30, 2012. On July 20, 2012 cash payments of approximately $18.0 million for aggregate dividends, distributions and dividend equivalents were made to common stockholders, common OP unitholders, and restricted stockholders of record as of July 10, 2012.

10.      Share-Based Compensation

In February 2012, we granted 15,000 shares of restricted stock to our executive officers under the 2009 Equity Plan. The awards vest ratably over an eight year period beginning on the fourth anniversary of the grant date, and have a fair value of $40.80 per share. The fair value was determined by using the closing share price of our common stock on the date the grant was issued.

During the six months ended June 30,2012, 7,678 shares of common stock were issued in connection with the exercise of stock options and the net proceeds received were $0.1 million.

The vesting requirements for 8,750 restricted shares granted to our employees were satisfied during the six months ended June 30,2012.

13.Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate swaps and caps are used to accomplish this objective. We require hedging derivative instruments to be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract.

As of June 30, 2012, we had four derivative contracts consisting of two interest rate swap agreements with a total notional amount of $45.0 million and two interest rate cap agreements with a notional amount of $162.4 million. We generally employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt and to cap the maximum interest rate on certain variable rate borrowings. We do not enter into derivative instruments for speculative purposes.

13.Derivative Instruments and Hedging Activities, continued

The following table provides the terms of our interestrate derivative contracts that were in effect as of June 30, 2012:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)	Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate
Swap	Floating to Fixed Rate	9/1/2002	7/1/2012	25.0	3 Month LIBOR	0.4682%	4.7000%	1.8700%	6.5700%

Cap	Cap Floating Rate	10/3/2011	10/3/2016	10.0	3 Month LIBOR	0.4600%	11.0200%	—%	N/A

Subsequent to June 30, 2012 the $25.0 million interest swap described in the above table matured and was not replaced.

Generally, our financial derivative instruments are designated and qualify as cash flow hedges and the effective portion of the gain or loss on such hedges are reported as a component of accumulated other comprehensive income (loss) in our Consolidated Balance Sheets. To the extent that the hedging relationship is not effective or do not qualify as a cash flow hedge, the ineffective portion is recorded in interest expense. Hedges that received designated hedge accounting treatment are evaluated for effectiveness at the time that they are designated as well as through the hedging period.

In accordance with ASC Topic 815, Derivatives and Hedging, we have recorded the fair value of our derivative instruments designated as cash flow hedges on the balance sheet. See Note 16 for information on the determination of fair value for the derivative instruments.  The following table summarizes the fair value of derivative instruments included in our Consolidated Balance Sheets as of June 30, 2012 and December 31, 2011 (in thousands):

	Asset Derivatives					Liability Derivatives
	Balance Sheet Location	Fair Value				Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments		June 30, 2012		December 31, 2011			June 30, 2012	December 31, 2011
Interest rate swaps and cap agreement	Other assets	$	—	$	—	Other liabilities	503	1,106
Total derivatives designated as hedging instruments		$	—	$	—		503	1,106

These valuation adjustments will only be realized under certain situations. For example, if we terminate the swaps prior to maturity or if the derivatives fail to qualify for hedge accounting, we would need to amortize amounts currently included in other comprehensive income (loss) into interest expense over the terms of the derivative contracts.  We do not intend to terminate the swaps prior to maturity and, therefore, the net of valuation adjustments through the various maturity dates will approximate zero, unless the derivatives fail to qualify for hedge accounting.

Our hedges were highly effective and had minimal effect on income.  The following table summarizes the impact of derivative instruments for the six months ended June 30,2012 and 2011 as recorded in the Consolidated Statements of Operations (in thousands):

Derivatives in cash flow hedging	Amount of Gain or (Loss) Recognized in OCI (Effective Portion)				Location of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)				Location of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)	Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)

13.Derivative Instruments and Hedging Activities, continued

Certain of our derivative instruments contain provisions that require us to provide ongoing collateralization on derivative instruments in a liability position.  As of June 30, 2012 and December 31, 2011, we had collateral deposits recorded in other assets of approximately $2.0 million and $3.1 million, respectively.

14.   Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) as defined under Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least ninety-five percent (95%) of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders.

Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended June 30, 2012.

As a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on the ordinary taxable income we distribute to our stockholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain state and local income taxes and to U.S. federal income and excise taxes on our undistributed income.

SHS, our taxable REIT subsidiary, is subject to U.S. federal income taxes. Our deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards and depreciation. A federal deferred tax asset of $1.0 million is included in other assets in our Consolidated Balance Sheets as of June 30, 2012 and December 31, 2011.

We had no unrecognized tax benefits as of June 30, 2012 and 2011. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2012.

We classify certain state taxes as income taxes for financial reporting purposes.  We record Texas Margin Tax as income taxes in our financial statements. In 2011 we were also subject to Michigan Business Tax that was replaced in May 2011 by a Corporate Income Tax. We believe that we will not have any corporate income tax liability under the new law. We recorded a provision for state income taxes of approximately $0.1 million for the six months ended June 30,2012 and a benefit of approximately $0.1 million for the six months ended June 30,2011.

15.   Earnings (Loss) Per Share

We have outstanding stock options and unvested restricted shares, and our Operating Partnership has Common OP Units, convertible A-1 preferred OP units and Aspen Preferred OP Units, which if converted or exercised, may impact dilution.  Although our unvested restricted shares qualify as participating securities, we do not include them in the computation of basic earnings (loss) per share under the two-class method in periods we report net losses, as the result would be anti-dilutive.

Computations of basic and diluted earnings per share from continuing operations were as follows (in thousands, except per share data):

	Three Months Ended June 30,					Six Months Ended June 30,
Numerator	2012		2011			2012		2011
Basic earnings: net income (loss) attributable to common stockholders	$	1,663	$	(890	)	$	7,040	$	1,510

Add: dilutive securities	16		—			17		2,078
Diluted weighted average common shares and securities	26,485		21,090			26,045		23,146
Earnings (loss) per share available to common stockholders:
Basic	$	0.06	$	(0.04	)	$	0.27	$	0.07
Diluted	$	0.06	$	(0.04	)	$	0.27	$	0.07

We excluded certain securities from the computation of diluted earnings per share because the inclusion of these securities would have been anti-dilutive for the periods presented.  The following table presents the number of outstanding potentially dilutive securities that were excluded from the computation of diluted earnings per share for the six months ended June 30,2012 and 2011 (amounts in thousands):

	Six Months Ended June 30,
	2012	2011
Stock options	57	78
Common OP units	2,070	—
A-1 preferred OP units	1,111	49
Aspen preferred OP units	526	526
Total securities	3,764	653

The figures above represent the total number of potentially dilutive securities, and do not necessarily reflect the incremental impact to the number of diluted weighted average shares outstanding that would be computed if the impact to us had been dilutive to the calculation of earnings per share available to common stockholders.

16.   Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 820, Fair Value Measurements and Disclosures, establishes guidance fair value hierarchy established by FASB guidance that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories:

Level 1—Quoted unadjusted prices for identical instruments in active markets.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all observable inputs and significant value drivers are observable in active markets.

Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by us.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value.

Derivative Instruments

The derivative instruments held by us are interest rate swaps and cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all observable inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair values of derivative instruments on a recurring basis.

Installment Notes on Manufactured Homes

The net carrying value of the installment notes on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates.

Long Term Debt and Lines of Credit

The fair value of long term debt (excluding the secured borrowing) is based on the estimates of management and on rates currently quoted and rates currently prevailing for comparable loans and instruments of comparable maturities.

Collateralized Receivables and Secured Borrowing

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing in the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates.

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

The table below sets forth our financial assets and liabilities that required disclosure of their fair values on a recurring basis as of June 30, 2012.  The table presents the carrying values and fair values of our financial instruments as of June 30, 2012 and December 31, 2011 that were measured using the valuation techniques described above. The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

17.   Recent Accounting Pronouncements

In April 2011, the FASB issued ASU 2011-03, “Reconsideration of Effective Control for Repurchase Agreements” (ASU 2011-03) which amends ASC Topic 860, Transfers and Servicing.  The updated guidance in ASC Topic 860 removes from the assessment of effective control (1) the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event of default by the transferee, and (2) the collateral maintenance implementation guidance related to that criterion. The updated guidance in ASC Topic 860 is effective for the first interim or annual period beginning on or after December 15, 2011.  Early adoption was not permitted.  The adoption of this guidance did not have any impact on our results of operations or financial condition.

In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04) which amends ASC Topic 820, Fair Value Measurement.  The updated guidance in ASC Topic 820 changes the wording used to describe the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements.   The updated guidance in ASC Topic 820 is effective during interim and annual periods beginning after December 15, 2011.  Early adoption was not permitted.  The adoption of this guidance did not have any impact on our results of operations or financial condition.

18.   Commitments and Contingencies

On June 4, 2010 we settled all of the claims arising out of the litigation filed in 2004 by TJ Holdings, LLC in the Superior Court of Guilford County, North Carolina and the associated arbitration proceeding commenced by TJ Holdings in Southfield, Michigan. Under the terms of the settlement agreement, in which neither party admitted any liability whatsoever, we paid TJ Holdings $360,000 . In addition, pursuant to this settlement, TJ Holdings’ percentage ownership interest in Sun/Forest, LLC will be increased on a one time basis, in the event of a sale or refinance of all of the SunChamp Properties, to between 9.03% and 28.99% depending on our average closing stock price as reported by the NYSE during the 30 days preceding the sale or refinance of all the SunChamp Properties. Once this percentage ownership interest has been adjusted, there will be no further adjustments from subsequent sales or refinances of the SunChamp Properties. The likelihood of a sale or refinancing of all of the SunChamp properties is not probable as these properties continue to see growth potential nor do we have a need to refinance all of the properties, so we do not expect it to have a material adverse impact on our results of operations or financial condition.

We are involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the consolidated financial condition and results of operations should be read in conjunction with the Consolidated Financial Statements and the notes thereto, along with our 2011 Annual Report. Capitalized terms are used as defined elsewhere in this Form 10-Q.

OVERVIEW

We are a self-administered and self-managed real estate investment trust, or REIT. We own, operate, and develop manufactured housing communities concentrated in the midwestern, southern, and southeastern United States. We are fully integrated real estate companies which, together with our affiliates and predecessors, have been in the business of acquiring, operating, and expanding manufactured housing communities since 1975. As of June 30, 2012, we owned and operated a portfolio of 162 properties located in 18 states (the “Properties” or “Property”), including 141 manufactured housing communities, 11 recreational vehicle communities, and 10 properties containing both manufactured housing and recreational vehicle sites. As of June 30, 2012, the Properties contained an aggregate of 55,921 developed sites comprised of 47,939 developed manufactured home sites and 7,982 recreational vehicle sites (“RV”) and approximately 6,450 manufactured home sites suitable for development. We lease individual parcels of land (“sites”) with utility access for placement of manufactured homes and recreational vehicles to our customers.  The Properties are designed to offer affordable housing to individuals and families, while also providing certain amenities.

We are engaged through a taxable subsidiary, SHS, in the marketing, selling, and leasing of new and pre-owned homes to current and future residents in our communities. The operations of SHS support and enhance our occupancy levels, property performance, and cash flows.

SIGNIFICANT ACCOUNTING POLICIES

We have identified significant accounting policies that, as a result of the judgments, uncertainties, and complexities of the underlying accounting standards and operations involved could result in material changes to our financial condition or results of operations under different conditions or using different assumptions. Details regarding significant accounting policies are described fully in our 2011 Annual Report.

SUPPLEMENTAL MEASURES

In addition to the results reported in accordance with GAAP, we have provided information regarding Net Operating Income (“NOI”) in the following tables. NOI is derived from revenues minus property operating expenses and real estate taxes. We use NOI as the primary basis to evaluate the performance of our operations. A reconciliation of NOI to net income attributable to Sun Communities, Inc. is included in “Results of Operations” below.

We believe that NOI is helpful to investors and analysts as a measure of operating performance because it is an indicator of the return on property investment, which provides a method of comparing property performance over time. We use NOI as a key management tool when evaluating performance and growth of particular properties and/or groups of properties. The principal limitation of NOI is that it excludes depreciation, amortization, interest expense, and non-property specific expenses such as general and administrative expenses, all of which are significant costs, and therefore, NOI is a measure of the operating performance of our properties rather than of the Company overall.  We believe that these costs included in net income often have no effect on the market value of our property and therefore limit its use as a performance measure. In addition, such expenses are often incurred at a parent company level and therefore are not necessarily linked to the performance of a real estate asset.

NOI should not be considered a substitute for the reported results prepared in accordance with GAAP. NOI should not be considered as an alternative to net income as an indicator of our financial performance, or to cash flows as a measure of liquidity; nor is it indicative of funds available for our cash needs, including our ability to make cash distributions.  NOI, as determined and presented by us, may not be comparable to related or similarly titled measures reported by other companies.

We also provide information regarding Funds From Operations (“FFO”).  A definition of FFO and a reconciliation of FFO to net income are included in the presentation of FFO in “Results of Operations” following the “Comparison of the Six Months Ended June 30, 2012 and 2011”.

SUN COMMUNITIES, INC.

RESULTS OF OPERATIONS

We report operating results under two segments: Real Property Operations and Home Sales and Rentals.  The Real Property Operations segment owns, operates, and develops manufactured housing communities and RV communities concentrated in the midwestern, southern, and southeastern United States and is in the business of acquiring, operating, and expanding manufactured housing and RV communities.  The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities.  We evaluate segment operating performance based on NOI and Gross Profit.

The accounting policies of the segments are the same as those applied in the Consolidated Financial Statements, except for the use of NOI. We may allocate certain common costs, primarily corporate functions, between the segments differently than we would for stand alone financial information prepared in accordance with GAAP. These allocated costs include expenses for shared services such as information technology, finance, communications, legal, and human resources. We do not allocate interest expense and certain other corporate costs not directly associated with the segments’ NOI and Gross Profit.

REAL PROPERTY OPERATIONS – SAME SITE

A key management tool used when evaluating performance and growth of our properties is a comparison of Same Site communities. Same Site communities consist of properties owned and operated for the same period in both years for the three months ended June 30,2012 and 2011.  The Same Site data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions, or unique situations.

In order to evaluate the growth of the Same Site communities, management has classified certain items differently than our GAAP statements.  The reclassification difference between our GAAP statements and our Same Site portfolio is the reclassification of water and sewer revenues from income from real property to utilities.  A significant portion of our utility charges are re-billed to our residents.   We reclassify these amounts to reflect the utility expenses associated with our Same Site portfolio net of recovery.

The following tables reflect certain financial and other information for our Same Site communities as of and for the three months ended June 30,2012 and 2011:

⁽³⁾  Weighted average rent pertains to manufactured housing and permanent recreational vehicle sites and excludes seasonal recreational vehicle sites.

Real Property NOI increased by $2.0 million, from $33.8 million to $35.8 million or 5.9 percent. The growth in NOI is primarily due to increased revenues of $2.3 million slightly offset by a $0.3 million increase in expenses.

Income from real property revenue consists of manufactured home and recreational vehicle site rent, and miscellaneous other property revenues.  Income from real property revenues increased $2.2 million, from $48.8 million to $51.0 million, or 4.7 percent.  The growth in income from real property was due to a combination of factors.  Revenue from our manufactured home and recreational vehicle portfolio increased by $2.4 million due to average rental rate increases of 3.1 percent and the increased number of occupied home sites and was partially offset by rent concessions offered to new residents and current residents who convert from home renters to home owners.  

Property operating expenses increased $0.3 million, from $15.0 million to $15.3 million, or 1.9 percent. Supplies and repairs increased by $0.4 million due to increased tree and lawn services, water system, road and pool repairs and community maintenance expenses. Other expenses increased $0.1 million primarily due to increased resident relations expenses. These increases were offset by decreased property and liability insurance expenses of $0.2 million.

OTHER INCOME STATEMENT ITEMS

Other revenues include other income, interest income, and ancillary revenues, net.  Other revenues increased by $0.5 million, from $2.4 million to $2.9 million, or 20.8 percent.  This was primarily due to an increase in interest income of $0.2 million from collateralized receivables, a $0.2 million increase in interest from installment note receivables, and a $0.1 million decrease in loan loss reserve.

Real Property general and administrative costs increased by $0.4 million, from $4.8 million to $5.2 million, or 8.3 percent due to an increase in payroll expenses of $0.1 million due to severance payments , an increase in human resource expenses of $0.1 million, an increase in legal expenses of $0.1 million, and an increase of $0.1 million in other expenses related to travel and other miscellaneous expenses.

Home Sales and Rentals general and administrative costs increased by $0.3 million, from $1.9 million to $2.2 million, or 15.8 percent due to increased salary and commission costs.

Acquisition related costs decreased by $0.7 million. These costs have been incurred for both closed and potential acquisitions.

Depreciation and amortization costs increased by $2.9 million, from $18.1 million to $21.0 million, or 16.0 percent due to increased depreciation on investment property for use in our Rental Program of $1.2 million and increased other depreciation and amortization of $1.7 million primarily due to the newly acquired properties (See Note 2).

Interest expense on debt, including interest on mandatorily redeemable debt, increased by $1.6 million, from $16.0 million to $17.6 million, or 10.0 percent due to an increase in expense associated with our secured borrowing arrangements of $0.2 million, an increase of $1.8 million in our mortgage interest due to debt associated with the acquired properties (see Note 2) and a higher rate on our FNMA debt, offset by a decrease in interest on our lines of credit of $0.4 million. 

Distributions from affiliates increased by $1.0 million, from $0.9 million to $1.9 million. We suspended equity accounting in 2010 as our investment balance is zero.  The income recorded in 2012 and 2011 is dividend income.

RESULTS OF OPERATIONS

We report operating results under two segments: Real Property Operations and Home Sales and Rentals.  The Real Property Operations segment owns, operates, and develops manufactured housing communities and RV communities concentrated in the midwestern, southern, and southeastern United States and is in the business of acquiring, operating, and expanding manufactured housing and RV communities.  The Home Sales and Rentals segment offers manufactured home sales and leasing services to tenants and prospective tenants of our communities.  We evaluate segment operating performance based on NOI and Gross Profit.

The accounting policies of the segments are the same as those applied in the Consolidated Financial Statements, except for the use of NOI. We may allocate certain common costs, primarily corporate functions, between the segments differently than we would for stand alone financial information prepared in accordance with GAAP. These allocated costs include expenses for shared services such as information technology, finance, communications, legal, and human resources. We do not allocate interest expense and certain other corporate costs not directly associated with the segments’ NOI and Gross Profit.

REAL PROPERTY OPERATIONS – SAME SITE

A key management tool used when evaluating performance and growth of our properties is a comparison of Same Site communities. Same Site communities consist of properties owned and operated for the same period in both years for the six months ended June 30,2012 and 2011.  The Same Site data may change from time-to-time depending on acquisitions, dispositions, management discretion, significant transactions, or unique situations.

In order to evaluate the growth of the Same Site communities, management has classified certain items differently than our GAAP statements. The reclassification difference between our GAAP statements and our Same Site portfolio is the reclassification of water and sewer revenues from income from real property to utilities.  A significant portion of our utility charges are re-billed to our residents. We reclassify these amounts to reflect the utility expenses associated with our Same Site portfolio net of recovery.

Real Property NOI increased by $4.6 million, from $70.1 million to $74.7 million or 6.6 percent. The growth in NOI is primarily due to increased revenues of $4.9 million partially offset by a $0.3 million increase in expenses.

Income from real property revenue consists of manufactured home and recreational vehicle site rent, and miscellaneous other property revenues.  Income from real property revenues increased $4.9 million, from $99.5 million to $104.4 million, or 5.0 percent.  The growth in income from real property was due to a combination of factors.  Revenue from our manufactured home and recreational vehicle portfolio increased by $5.3 million due to average rental rate increases of 3.1 percent and the increased number of occupied home sites and was partially offset by rent concessions offered to new residents and current residents who convert from home renters to home owners.  Additionally, revenue realized on cable television royalties and utility income decreased by $0.3 million and $0.1 million respectively.

Property operating expenses increased $0.3 million, from $29.4 million to $29.7 million, or 1.1 percent. Supplies and repairs increased by $0.4 million due to increased lawn services, water and sewer system repairs, garage and shed repairs, and community maintenance expenses. Other expenses increased $0.4 million primarily due to increased meeting, office, and resident relations expenses . These increases were offset by decreased property insurance expenses of $0.4 million and decreased utilities expenses of $0.1 million.

OTHER INCOME STATEMENT ITEMS

Other revenues include other income, interest income, and ancillary revenues, net.  Other revenues increased by $1.1 million, from $4.8 million to $5.9 million, or 22.9 percent.  This was primarily due to an increase in interest income of $0.5 million from collateralized receivables, a $0.2 million increase in interest income from installment note receivables, a $0.1 million increase from gain on sale of land, a $0.2 million decrease in loan loss reserve, and a $0.1 million increase in management fees and other miscellaneous income.

Real Property general and administrative costs increased by $0.9 million, from $9.3 million to $10.2 million, or 9.7 percent due to an increase in payroll expenses of $0.3 million due to severance payments, additional staff and increased wages, an increase in training and recruiting expenses of $0.1 million, an increase in legal expenses of $0.1 million, and an increase of $0.4 million in other expenses primarily related to travel expenses, software support and maintenance costs, licenses and dues and rent.

Home Sales and Rentals general and administrative costs increased by $0.5 million, from $3.9 million to $4.4 million, or 12.8 percent due to increased salary and commission costs.

Acquisition related costs decreased by $0.8 million.These costs have been incurred for both closed and potential acquisitions.

Depreciation and amortization costs increased by $6.1 million, from $34.8 million to $40.9 million, or 17.5 percent due to increased depreciation on investment property for use in our Rental Program of $2.4 million and increased other depreciation and amortization of $3.7 million primarily due to the newly acquired properties (See Note 2).

Interest expense on debt, including interest on mandatorily redeemable debt, increased by $3.0 million, from $32.3 million to $35.3 million, or 9.3 percent due to an increase in expense associated with our secured borrowing arrangements of $0.5 million, an increase of $3.2 million in our mortgage interest due to debt associated with the acquired properties (see Note 2) and a higher rate on our FNMA debt, offset by a decrease in interest on our lines of credit of $0.7 million. 

Distributions from affiliates increased by $1.5 million, from $1.2 million to $2.7 million. We suspended equity accounting in 2010 as our investment balance is zero.  The income recorded in 2012 and 2011 is dividend income.

FUNDS FROM OPERATIONS

We provide information regarding FFO as a supplemental measure of operating performance.  FFO is defined by the NAREIT as net income (loss) (computed in accordance GAAP), excluding gains (or losses) from sales of depreciable operating property, plus real estate-related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Due to the variety among owners of identical assets in similar condition (based on historical cost accounting and useful life estimates), we believe excluding gains and losses related to sales of previously depreciated operating real estate assets, impairment and excluding real estate asset depreciation and amortization, provides a better indicator of our operating performance.  FFO is a useful supplemental measure of our operating performance because it reflects the impact to operations from trends in occupancy rates, rental rates, and operating costs, providing perspective not readily apparent from net income (loss).  Management believes that the use of FFO has been beneficial in improving the understanding of operating results of REITs among the investing public and making comparisons of REIT operating results more meaningful. Management, the investment community, and banking institutions routinely use FFO, together with other measures, to measure operating performance in our industry. Further, management uses FFO for planning and forecasting future periods.

Because FFO excludes significant economic components of net income (loss) including depreciation and amortization, FFO should be used as an adjunct to net income (loss) and not as an alternative to net income (loss). The principal limitation of FFO is that it does not represent cash flow from operations as defined by GAAP and is a supplemental measure of performance that does not replace net income (loss) as a measure of performance or net cash provided by operating activities as a measure of liquidity. In addition, FFO is not intended as a measure of a REIT’s ability to meet debt principal repayments and other cash requirements, nor as a measure of working capital. FFO only provides investors with an additional performance measure. FFO is compiled in accordance with its interpretation of standards established by NAREIT, which may not be comparable to FFO reported by other REITs that do not define the term in accordance with the current NAREIT definition or that interpret the current NAREIT definition differently.

The following table reconciles net income (loss) to FFO data for diluted purposes for the periods ended June 30, 2012, and 2011 (in thousands):

LIQUIDITY AND CAPITAL RESOURCES

Our principal liquidity demands have historically been, and are expected to continue to be, distributions to our stockholders and the unitholders of the Operating Partnership, capital improvements of properties, the purchase of new and pre-owned homes, property acquisitions, development and expansion of properties, and debt repayment.

We expect to meet our short-term liquidity requirements through working capital provided by operating activities and through borrowings on our lines of credit. We consider these resources to be adequate to meet our operating requirements, including recurring capital improvements, routinely amortizing debt and other normally recurring expenditures of a capital nature, payment of dividends to our stockholders to maintain qualification as a REIT in accordance with the Code, and payment of distributions to our Operating Partnership’s unitholders.

We completed four acquisitions in 2011 in which we acquired 23 properties in total, 18 manufactured housing communities and 5 recreational vehicle communities. We completed one acquisition in 2012 in which we acquired three recreational vehicle communities. See Note 2 for details on the acquisitions.  We will continue to evaluate acquisition opportunities that meet our criteria for acquisition. Should additional investment opportunities arise in 2012, we intend to finance the acquisitions through secured financing, debt and/or equity financings, the assumption of existing debt on the properties or the issuance of certain equity securities.

During the six months ended June 30,2012, we have invested $29.8 million in the acquisition of homes intended for the Rental Program net of proceeds from third party financing from homes sales.  Expenditures for 2012 will be dependent upon the condition of the markets for repossessions and new home sales, as well as rental homes. We finance new home purchases with a $12.0 million floor plan facility. Our ability to purchase homes for sale or rent may be limited by cash received from third party financing of our home sales, available floor plan financing and working capital available on our secured lines of credit.

Cash and cash equivalents decreased by $1.4 million from $5.9 million as of December 31, 2011, to $4.5 million as of June 30, 2012. Net cash provided by operating activities from continuing operations increased by $14.4 million from $29.1 million for the six months ended June 30,2011 to $43.5 million for the six months ended June 30,2012.

Our net cash flows provided by operating activities from continuing operations may be adversely impacted by, among other things: (a) the market and economic conditions in our current markets generally, and specifically in metropolitan areas of our current markets; (b) lower occupancy and rental rates of our properties; (c) increased operating costs, such as wage and benefit costs, insurance premiums, real estate taxes and utilities, that cannot be passed on to our tenants; (d) decreased sales of manufactured homes and (e) current volatility in economic conditions and the financial markets.  See “Risk Factors” in our 2011 Annual Report.

We have a secured revolving line of credit facility with a maximum borrowing capacity of $130.0 million, subject to certain borrowing base calculations. As of June 30, 2012, we had an outstanding balance on the line of credit of $20.1 million. The outstanding balance on the line of credit as of December 31, 2011 was $107.5 million. $4.0 million of availability was used to back standby letters of credit as of June 30, 2012 and December 31, 2011. Borrowings under the line of credit bear a floating interest rate based on Eurodollar plus a margin that is determined based on our leverage ratio calculated in accordance with the line of credit agreement, which can range from 2.25% to 2.95%.  As of June 30, 2012, $105.9 million was available to be drawn under the facility based on the calculation of the borrowing base.  During 2012, the highest balance on the line of credit was $107.5 million.  The borrowings under the line of credit mature October 1, 2015, assuming the election of a one year extension that is available at our discretion, subject to certain conditions. Although the secured revolving line of credit is a committed facility, the financial failure of one or more of the participating financial institutions may reduce the amount of available credit for use by us.

The line of credit facility contains various leverage, fixed charge coverage, net worth maintenance and other customary covenants all of which we were in compliance with as of June 30, 2012. The most limiting covenants contained in the line of credit are the maximum leverage ratio and minimum fixed charge coverage ratios. The maximum leverage ratio covenant requires that total indebtedness be no more than 70 percent of total asset value as defined in the terms of the line of credit agreement.  The minimum fixed charge coverage ratio covenant requires a minimum ratio of 1.45:1.  As of June 30, 2012, the leverage ratio was 57.1% and the fixed charge coverage ratio was 1.93:1.

Although the U.S. economy has started to recover from the global financial crisis and recession, the rate of recovery has been much slower than anticipated. Forecasts for economic growth over the next year have been downsized, due in large part to the recent turbulence in the US and global markets. While bank earnings and liquidity are on the rebound, the potential of significant future credit losses clouds the lending outlook. Credit availability has improved, but the turbulence in the markets cause capital markets and credit availability to wax and wane unpredictably making certainty of access to specific forms of capital products tenuous. For us, this is the most relevant consequence of financial market volatility. We believe this risk is somewhat mitigated because we are able to utilize various forms of capital to fund our operations making availability to one specific form of capital less vital and have adequate working capital provided by operating activities as noted above. We anticipate meeting our long-term liquidity requirements, such as scheduled debt maturities, large property acquisitions, and Operating Partnership unit redemptions through the issuance of certain debt or equity securities and/or the collateralization of our properties. We currently have 33 unencumbered properties with an estimated market value of $249.9 million, most of which support the borrowing base for our $130.0 million secured line of credit.  From time to time, we may also issue shares of our capital stock or preferred stock, issue equity units in our Operating Partnership, obtain debt financing, or sell selected assets. Our ability to finance our long-term liquidity requirements in such a manner will be affected by numerous economic factors affecting the manufactured housing community industry at the time, including the availability and cost of mortgage debt, our financial condition, the operating history of the properties, the state of the debt and equity markets, and the general national, regional, and local economic conditions. When it becomes necessary for us to approach the credit markets, the volatility in those  markets could make borrowing more difficult to secure, more expensive, or effectively unavailable.  See “Risk Factors” in Item 1A of our 2011 Annual Report.  If we are unable to obtain additional debt or equity financing on acceptable terms, our business, results of operations and financial condition would be adversely impacted.

As of June 30, 2012, our debt to total market capitalization approximated 50.9 percent (assuming conversion of all Common Operating Partnership Units to shares of common stock). Our debt has a weighted average maturity of approximately 6.9 years and a weighted average interest rate of 5.3 percent.

Capital expenditures for the six months ended June 30,2012 and 2011 included recurring capital expenditures of $3.6 million and $2.9 million, respectively. We are committed to the continued upkeep of our Properties and therefore do not expect a significant decline in our recurring capital expenditures during 2012.

Net cash used in investing activities was $87.1 million for the six months ended June 30,2012, compared to $87.4 million for the six months ended June 30,2011. The difference is primarily due to decreased acquisitions of $26.4 million (see Note 2) and an increase in proceeds from affiliate dividend distribution of $1.4 million, offset by a decrease in proceeds from the disposition of homes and assets of $0.9 million, an increase in notes receivable of $5.2 million, and increased investment in property of $21.4 million, largely due to homes purchased for the Rental Program primarily in the acquired communities and expansion projects.  

Net cash provided by financing activities was $42.3 million for the six months ended June 30,2012, compared to of $53.9 million for the six months ended June 30,2011. The difference is due to decreased net borrowings on the line of credit of $98.2 million, decreased proceeds from issuance of other debt net of repayments on other debt of $19.2 million, increased distributions to our stockholders and OP unitholders of $5.2 million and decreased net proceeds for stock option exercise of $0.5 million partially offset by increased net proceeds received from the issuance of additional shares of $110.2 million and decreased payments of deferred financing costs of $1.3 million.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our principal market risk exposure is interest rate risk. We mitigate this risk by maintaining prudent amounts of leverage, minimizing capital costs and interest expense while continuously evaluating all available debt and equity resources and following established risk management policies and procedures, which include the periodic use of derivatives. Our primary strategy in entering into derivative contracts is to minimize the variability interest rate changes could have on our future cash flows. We generally employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt. We do not enter into derivative instruments for speculative purposes.

We have four derivative contracts consisting of two interest rate swap agreements with a total notional amount of $45.0 million, and two interest rate cap agreements with a notional amount of $162.4 million as of June 30, 2012. The first swap agreement fixes $25.0 million of variable rate borrowings at 6.57 percent through July 2012. Subsequent to June 30, 2012, this swap matured and was not replaced.  The second swap agreement fixes $20.0 million of variable rate borrowings at 4.02 percent through January 2014. The first interest cap agreement has a cap rate of 11.27 percent, a notional amount of $152.4 million, and a termination date of April 2015.  The second interest cap agreement has a cap rate of 11.02 percent, a notional amount of $10.0 million through October 2016.

Our remaining variable rate debt totals $242.3 million and $265.6 million as of June 30, 2012 and 2011, respectively, which bear interest at Prime or various LIBOR rates. If Prime or LIBOR increased or decreased by 1.0 percent during the six months ended June 30,2012 and 2011, we believe our interest expense would have increased or decreased by approximately $1.2 million based on the $237.5 million and $231.9 million average balances outstanding under our variable rate debt facilities for the six months ended June 30,2012 and 2011.

ITEM 4.  CONTROLS AND PROCEDURES

(a) Under the supervision and with the participation of our management, including the Chief Executive Officer, Gary A. Shiffman, and Chief Financial Officer, Karen J. Dearing, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this quarterly report, pursuant to Rule 13a-15 of the Securities Exchange Act of 1934 (the “Exchange Act”). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures as of the end of the period covered by this report were effective to ensure that information we are required to disclose in our filings with the SEC under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information we are required to disclose in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

(b) There have been no changes in our internal control over financial reporting during the quarterly period ended June 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Commitments and Contingencies Disclosure [Abstract]

Commitments And Contingencies

Commitments and Contingencies

On June 4, 2010 we settled all of the claims arising out of the litigation filed in 2004 by TJ Holdings, LLC in the Superior Court of Guilford County, North Carolina and the associated arbitration proceeding commenced by TJ Holdings in Southfield, Michigan. Under the terms of the settlement agreement, in which neither party admitted any liability whatsoever, we paid TJ Holdings $360,000 . In addition, pursuant to this settlement, TJ Holdings’ percentage ownership interest in Sun/Forest, LLC will be increased on a one time basis, in the event of a sale or refinance of all of the SunChamp Properties, to between 9.03% and 28.99% depending on our average closing stock price as reported by the NYSE during the 30 days preceding the sale or refinance of all the SunChamp Properties. Once this percentage ownership interest has been adjusted, there will be no further adjustments from subsequent sales or refinances of the SunChamp Properties. The likelihood of a sale or refinancing of all of the SunChamp properties is not probable as these properties continue to see growth potential nor do we have a need to refinance all of the properties, so we do not expect it to have a material adverse impact on our results of operations or financial condition.

We are involved in various other legal proceedings arising in the ordinary course of business. All such proceedings, taken together, are not expected to have a material adverse impact on our results of operations or financial condition.

Real Estate Acquisitions

Real Estate Acquisitions

In May 2011, we acquired Orange City RV Resort (“Orange City”), a Florida recreational vehicle community comprising 525 developed sites.  In June 2011, we closed on the acquisition of Kentland Communities (“Kentland”), comprising 17 manufactured home communities and one recreational vehicle community.  The 18 communities acquired are located in western Michigan and comprise 5,434 developed sites.  In November 2011, we acquired Cider Mill Crossings (“Cider Mill”), a Michigan manufactured home community comprising 262 developed sites through an auction. In December 2011, we acquired three Florida RV communities, Club Naples RV Resort, Kountree RV Resort, and North Lake RV Resort (collectively the “Florida Properties”), two of which are in Naples, Florida and one of which is in Moore Haven, Florida, comprised of 740 developed sites. These acquisitions complement our existing portfolio and create both short-term and long-term growth opportunities.

In February 2012, we acquired three additional Florida RV communities, Three Lakes RV Resort, Blueberry Hill RV Resort and Grand Lake Estates (collectively, the “Additional Florida Properties”), one of which is located in Hudson, Florida, one of which is located in Bushnell, Florida and one of which is located in Orange Lake, Florida, comprised of 1,114 RV sites in the aggregate. We believe this portfolio provides for growth from both rental increases and through improved seasonal occupancy.

On July 24, 2012 we acquired Blazing Star, a recreational vehicle community with 260 sites located in San Antonio, Texas, for a purchase price of $7.1 million, comprised of $4.1 million of assumed debt and $3.0 million of cash.

Acquisition related costs of approximately $0.6 million and $1.4 million have been incurred for the six months ended June 30,2012 and 2011, respectively, and are presented as “Acquisition related costs” in our Consolidated Statements of Operations.

During the third quarter of 2011, we completed the purchase price allocation for Kentland and Orange City. In the first quarter of 2012 some of the amounts previously estimated changed. The changes in estimates included a decrease in other assets of $0.8 million and a decrease in cash consideration of $0.8 million for the Florida Properties. The measurement period adjustments represent updates made to the purchase price allocation based on the escrow amount required for the Additional Florida Properties which is reflected in the purchase price allocation for the Additional Florida Properties. There were no significant adjustments to our Consolidated Statements of Operations.

The purchase price allocation for Cider Mill, the Florida Properties, and the Additional Florida Properties is preliminary and may be adjusted as final costs and final valuations are determined.

⁽¹⁾ Subsequent to the acquisition, on March 30, 2012, the Additional Florida Properties were encumbered with a $19.0 million loan through Bank of America and The PrivateBank (See Note 8).

As of June 30, 2012, the total residual value of the acquired in-place leases above is $8.2 million. The amortization period is 7 years.

The results of operations of Kentland, Orange City, Cider Mill, the Florida Properties, and the Additional Florida Properties are included in the Consolidated Statements of Operations beginning on their acquisition dates of June 2011, May 2011, November 2011, December 2011, and February 2012, respectively. The following unaudited pro forma financial information presents the results of our operations for the six months ended June 30,2012 and 2011 as if the properties were acquired on January 1, 2010 for those communities acquired in 2011 and January 1, 2011 for those that were acquired in 2012. The unaudited pro forma results have been prepared for comparative purposes only and do not purport to be indicative of either the results of operations that would have actually occurred or the future results of operations (in thousands, except per-share data). ⁽¹⁾

⁽¹⁾ Below are nonrecurring expenses that have been adjusted for the pro forma results above:

(a) The sellers had management fees of $0.7 million for the six months ended June 30,2011 that have been excluded from above as these fees will not continue going forward.

(b) Transaction costs related to the acquisitions are not expected to have a continuing impact and therefore have been excluded from 2012 and included in 2011.

The amount of Kentland's, Orange City's, Cider Mill's, the Florida Properties', and the Additional Florida Properties' revenue and net income included in the Consolidated Statements of Operations for the six months ended June 30,2012 is set forth in the following table (in thousands):

Earnings Per Share

Earnings (Loss) Per Share

We have outstanding stock options and unvested restricted shares, and our Operating Partnership has Common OP Units, convertible A-1 preferred OP units and Aspen Preferred OP Units, which if converted or exercised, may impact dilution.  Although our unvested restricted shares qualify as participating securities, we do not include them in the computation of basic earnings (loss) per share under the two-class method in periods we report net losses, as the result would be anti-dilutive.

Computations of basic and diluted earnings per share from continuing operations were as follows (in thousands, except per share data):

We excluded certain securities from the computation of diluted earnings per share because the inclusion of these securities would have been anti-dilutive for the periods presented.  The following table presents the number of outstanding potentially dilutive securities that were excluded from the computation of diluted earnings per share for the six months ended June 30,2012 and 2011 (amounts in thousands):

Total securities	3,764	653

The figures above represent the total number of potentially dilutive securities, and do not necessarily reflect the incremental impact to the number of diluted weighted average shares outstanding that would be computed if the impact to us had been dilutive to the calculation of earnings per share available to common stockholders.

Recent Accounting Pronouncements

In April 2011, the FASB issued ASU 2011-03, “Reconsideration of Effective Control for Repurchase Agreements” (ASU 2011-03) which amends ASC Topic 860, Transfers and Servicing.  The updated guidance in ASC Topic 860 removes from the assessment of effective control (1) the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event of default by the transferee, and (2) the collateral maintenance implementation guidance related to that criterion. The updated guidance in ASC Topic 860 is effective for the first interim or annual period beginning on or after December 15, 2011.  Early adoption was not permitted.  The adoption of this guidance did not have any impact on our results of operations or financial condition.

In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04) which amends ASC Topic 820, Fair Value Measurement.  The updated guidance in ASC Topic 820 changes the wording used to describe the requirements in U.S. GAAP for measuring fair value and for disclosing information about fair value measurements.   The updated guidance in ASC Topic 820 is effective during interim and annual periods beginning after December 15, 2011.  Early adoption was not permitted.  The adoption of this guidance did not have any impact on our results of operations or financial condition.

Share-Based Compensation

In February 2012, we granted 15,000 shares of restricted stock to our executive officers under the 2009 Equity Plan. The awards vest ratably over an eight year period beginning on the fourth anniversary of the grant date, and have a fair value of $40.80 per share. The fair value was determined by using the closing share price of our common stock on the date the grant was issued.

During the six months ended June 30,2012, 7,678 shares of common stock were issued in connection with the exercise of stock options and the net proceeds received were $0.1 million.

The vesting requirements for 8,750 restricted shares granted to our employees were satisfied during the six months ended June 30,2012.

Transfers Of Financial Assets

Transfers and Servicing [Abstract]

Transfers Of Financial Assets

Transfers of Financial Assets

We completed various transactions with an unrelated entity involving our notes receivable during 2012 under which we received a total of $11.5 million of cash proceeds in exchange for relinquishing our right, title and interest in certain notes receivable. We have no further obligations or rights with respect to the control, management, administration, servicing, or collection of the installment notes. However, we are subject to certain recourse provisions requiring us to purchase the underlying homes collateralizing such notes, in the event of a note default and subsequent repossession of the home by the unrelated entity. The recourse provisions are considered to be a form of continuing involvement, and therefore these transferred loans did not meet the requirements for sale accounting. We continue to recognize these transferred loans on our balance sheet and refer to them as collateralized receivables as a transfer of financial assets. The proceeds from the transfer have been recognized as a secured borrowing.

In the event of note default, and subsequent repossession of a manufactured home by the unrelated entity, the terms of the agreement require us to repurchase the manufactured home. Default is defined as the failure to repay the installment note according to contractual terms. The repurchase price is calculated as a percentage of the outstanding principal balance of the collateralized receivable, plus any outstanding late fees, accrued interest, legal fees, and escrow advances associated with the installment note.  The percentage used to determine the repurchase price of the outstanding principal balance on the installment note is based on the number of payments made on the note. In general, the repurchase price is determined as follows:

Number of Payments	Repurchase %
Less than or equal to 15	100	%
Greater than 15 but less than 64	90	%
Equal to or greater than 64 but less than 120	65	%
120 or more	50	%

The transferred assets have been classified as collateralized receivables in Notes and Other Receivables (see Note 5) and the cash proceeds received from these transactions have been classified as a secured borrowing in Debt (see Note 8) within the Consolidated Balance Sheets. The balance of the collateralized receivables was $86.5 million (net of allowance of $0.5 million ) and $81.2 million (net of allowance of $0.5 million) as of June 30, 2012 and December 31, 2011, respectively.  The outstanding balance on the secured borrowing was $87.1 million and $81.7 million as of June 30, 2012 and December 31, 2011, respectively.

The balances of the collateralized receivables and secured borrowings fluctuate. The balances increase as additional notes receivable are transferred and exchanged for cash proceeds. The balances are reduced as the related collateralized receivables are collected from the customers, or as the underlying collateral is repurchased. The change in the aggregate gross principal balance of the collateralized receivables is as follows (in thousands):

	Six Months Ended			Year Ended
	June 30, 2012			December 31, 2011
Beginning balance	$	81,682		$	71,278
Financed sales of manufactured homes	11,467			21,509
Principal payments and payoffs from our customers	(2,671		)	(4,425		)
Principal reduction from repurchased homes	(3,409		)	(6,680		)
Total activity	5,387			10,404
Ending balance	$	87,069		$	81,682

The collateralized receivables earn interest income and the secured borrowings accrue interest expense at the same interest rates. The amount of interest income and expense recognized was $4.4 million and $4.0 million for the six months ended June 30,2012 and 2011, respectively.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value Of Financial Instruments

Fair Value of Financial Instruments

Our financial instruments consist primarily of cash and cash equivalents, accounts and notes receivable, accounts payable, derivative instruments, and debt.

ASC Topic 820, Fair Value Measurements and Disclosures, establishes guidance fair value hierarchy established by FASB guidance that requires the use of observable market data, when available, and prioritizes the inputs to valuation techniques used to measure fair value in the following categories:

Level 1—Quoted unadjusted prices for identical instruments in active markets.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations in which all observable inputs and significant value drivers are observable in active markets.

Level 3—Model derived valuations in which one or more significant inputs or significant value drivers are unobservable, including assumptions developed by us.

We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value.

Derivative Instruments

The derivative instruments held by us are interest rate swaps and cap agreements for which quoted market prices are indirectly available. For those derivatives, we use model-derived valuations in which all observable inputs and significant value drivers are observable in active markets provided by brokers or dealers to determine the fair values of derivative instruments on a recurring basis.

Installment Notes on Manufactured Homes

The net carrying value of the installment notes on manufactured homes estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates.

Long Term Debt and Lines of Credit

The fair value of long term debt (excluding the secured borrowing) is based on the estimates of management and on rates currently quoted and rates currently prevailing for comparable loans and instruments of comparable maturities.

Collateralized Receivables and Secured Borrowing

The fair value of these financial instruments offset each other as our collateralized receivables represent a transfer of financial assets and the cash proceeds received from these transactions have been classified as a secured borrowing in the Consolidated Balance Sheets. The net carrying value of the collateralized receivables estimates the fair value as the interest rates in the portfolio are comparable to current prevailing market rates.

Other Financial Instruments

The carrying values of cash and cash equivalents, accounts receivable, and accounts payable approximate their fair market values due to the short-term nature of these instruments.

The table below sets forth our financial assets and liabilities that required disclosure of their fair values on a recurring basis as of June 30, 2012.  The table presents the carrying values and fair values of our financial instruments as of June 30, 2012 and December 31, 2011 that were measured using the valuation techniques described above. The table excludes other financial instruments such as cash and cash equivalents, accounts receivable, and accounts payable because the carrying values associated with these instruments approximate fair value since their maturities are less than one year.

Collateralized Term Loans

In March, 2011, we completed a collateralized mortgage backed security “CMBS” financing with JPMorgan Chase Bank, National Association for $115.0 million bearing an interest rate of 5.837% and a maturity date of March 1, 2021. This loan is secured by 11 properties. The loan refinanced $104.8 million of CMBS debt which was scheduled to mature in July 2011 and was collateralized using the same property pool.

In May 2011, we completed a refinancing agreement with Bank of America N.A., for $23.6 million. This debt bears an interest rate of 5.38% and has a maturity of June 1, 2021. This loan is secured by three properties. The loan refinanced $17.9 million of debt which was scheduled to mature in June 2012 and was collateralized using the same property pool.

In July 2011, we reached an agreement with Fannie Mae (“FNMA”) and PNC Bank, National Association, regarding the settlement of the litigation we commenced in November 2009 over certain fees charged when the variable rate loan facility was extended in April 2009. The agreement became effective January 3, 2012 and the litigation was dismissed. In accordance with the terms of the agreement, we have the option to extend the maturity date of our entire $367.0 million credit facility with PNC Bank and FNMA from 2014 to 2023, subject to compliance with certain underwriting criteria. This agreement also provided a reduction in the facility fee charged on our variable rate facility for 2011. In addition we drew a $10.0 million variable rate facility, which matures on May 1, 2023 and provides for interest-only payments until May 1, 2014, after which principal and interest payments will be due based on a 30-year amortization.  The interest rate for the $10.0 million variable rate facility is equal to the 90-day LIBOR index, plus an investor spread equal to 95 basis points, plus a variable facility fee equal to 172 basis points through maturity.

The collateralized term loans totaling $1.0 billion as of June 30, 2012, are secured by 96 properties comprised of 35,107 sites representing approximately $574.8 million of net book value.

Aspen preferred OP Units and Series B-3 preferred OP units

The Aspen preferred OP units are convertible into 526,212 common shares based on a conversion price of $68 per share with a redemption date of January 1, 2024. The minimum and maximum annual preferred rate is 6.5 percent and 9.0 percent, respectively. The current preferred rate is 6.5 percent.

We redeemed $1.0 million of Series B-3 preferred OP units in May 2012.

Secured Borrowing

See Note 4 for additional information regarding our collateralized receivables and secured borrowing transactions.

Mortgage Notes

In June 2011, we assumed secured debt with a principal balance of $52.4 million, as a result of the Kentland acquisition (see Note 2 for acquisition details), that had a weighted average maturity of 4.4 years and weighted average annual interest rate of 5.70% at the date of acquisition. This secured debt was recorded at fair value on the date of the acquisition which was equal to the assumed

principal balance. This debt is secured by 12 properties. The current weighted average maturity is 3.9 years with the current weighted average annual variable interest rate of 5.61%.

In June 2011, we entered into a $22.9 million variable financing agreement with Bank of America N.A., to fund the Kentland and Orange City acquisition (see Note 2 for acquisition details). The agreement has a weighted average maturity of 3.7 years and weighted average annual variable interest rate of 3.10% at the date of acquisition. The debt was collateralized by six properties – five Kentland properties and Orange City. On February 1, 2012, we paid off $4.5 million of this agreement which was collateralized by Orange City. The current weighted average maturity is 2.9 years with the current weighted average annual variable interest rate of 3.10%.

In December 2011, we entered into a $17.0 million variable financing agreement with Bank of America, N.A. and The Private Bank to fund the Florida Properties acquisition (see Note 2 for acquisition details). The agreement has a weighted average maturity of 5.0 years and had an effective interest rate of 2.78% at the date of acquisition. The debt was collateralized by all three of the properties acquired in the Florida Properties acquisition. The current weighted average maturity is 4.5 years with the current weighted average annual variable interest rate of 2.75%.

In March 2012, we entered into an amended and restated variable financing agreement with Bank of America, N.A. and The PrivateBank which added an additional $19.0 million to the December 2011 variable financing agreement, the "36.0 Million Facility." The agreement has a weighted average maturity of 4.7 years and had an effective interest rate of 2.74% at the date of acquisition. The debt is collateralized by the three properties acquired in the Additional Florida Properties acquisition.

In March 2012, we paid off the entire $2.7 million mortgage agreement secured by Leisure Village which was due to mature on April 1, 2012.

In June 2012, we completed a variable refinancing agreement with Bank of America N.A., for $14.1 million. This debt bears an interest rate of LIBOR plus a 2.0% margin (effective rate at June 30, 2012 was 2.25%) and has a maturity of September 1, 2016, assuming the election of the two successive one-year extensions. The loan is secured by two properties and refinanced $14.0 million of debt which matured in June 2012.

The mortgage notes totaling $154.0 million as of June 30, 2012, are collateralized by 31 properties comprised of 8,160 sites representing approximately $256.3 million of net book value.

Lines of Credit

In September 2011, we entered into a senior secured revolving credit facility with Bank of America, N.A., and certain other lenders in the amount of $130.0 million (the "Facility"), which replaced our $115.0 million revolving line of credit.  The Facility is secured by a first priority lien on all of our equity interests in each entity that owns all or a portion of the properties constituting the borrowing base and collateral assignments of our senior and mezzanine debt positions in certain borrowing base properties. The Facility has a built-in accordion feature allowing up to $20.0 million in additional borrowings and a one-year extension option, both at our discretion. The Facility matures on October 1, 2015, assuming the election of the extension. The Facility bears interest at a floating rate based on Eurodollar plus a margin that is determined based on our leverage ratio calculated in accordance with the Facility, which can range from 2.25% to 2.95%. Based on our calculation of the leverage ratio as of June 30, 2012, the margin is 2.50% . The outstanding balance on the line of credit was $20.1 million and $107.5 million as of June 30, 2012 and December 31, 2011, respectively. In addition, $4.0 million of availability was used to back standby letters of credit as of June 30, 2012 and December 31, 2011. As of June 30, 2012 and December 31, 2011, $105.9 million and $18.5 million, respectively, were available to be drawn under the facility based on the calculation of the borrowing base at each date.

We have a $20.0 million secured line of credit agreement collateralized by a portion of our rental home portfolio. The net book value of the rental homes pledged as security for the loan must meet or exceed 200 percent of the outstanding loan balance. The terms of the agreement require interest only payments for the first 5 years, with the remainder of the term being amortized based on a 10 year term. The current effective interest rate is Prime plus 200 basis points, or 5.5 percent at June 30, 2012. Prime shall mean the prime rate published in the Wall Street Journal adjusted the first day of each calendar month. The outstanding balance was zero as of June 30, 2012. The outstanding balance was $16.0 million as of December 31, 2011.

We have a $12.0 million manufactured home floor plan facility renewable indefinitely until our lender provides us 12 month notice of their intent to terminate the agreement. The interest rate is 100 basis points over the greater of Prime or 6.0 percent (effective

8.      Debt and Lines of Credit, continued

rate 7.0 percent at June 30, 2012).  Prime means the prevailing “prime rate” as quoted in the Wall Street Journal on the first business day of each month. The outstanding balance was $4.5 million and $5.5 million as of June 30, 2012 and December 31, 2011, respectively.

As of June 30, 2012, the total of maturities and amortization of debt and lines of credit during the next five years, are as follows (in thousands):

The most restrictive of our debt agreements place limitations on secured borrowings and contain minimum fixed charge coverage, leverage, distribution and net worth requirements. As of June 30, 2012, we were in compliance with all covenants except that our subsidiaries that own the Florida Properties and the Additional Florida Properties were not in compliance with the debt service coverage ratio contained in the $36.0 Million Facility. There is no Event of Default under the $36.0 Million Facility. We have requested a waiver of such covenant for a specified period of time and, if we are unable to obtain such waiver, we intend to comply with this covenant by voluntarily paying down a portion of the $36.0 Million Facility in accordance with the loan agreement.

Origen Financial Services, LLC (“OFS LLC”)

At June 30, 2012 and 2011, we had a 22.9 percent ownership interest in OFS LLC, an entity formed to originate manufactured housing installment contracts.  We have suspended equity accounting as the carrying value of our investment is zero.

Origen Financial, Inc. (“Origen”)

Through Sun OFI, LLC, a taxable REIT subsidiary, we own 5,000,000 shares of common stock of Origen which approximates an ownership interest of 19 percent. Although it is no longer originating or servicing loans, Origen continues to manage an existing portfolio of manufactured home loans and asset backed securities. We have suspended equity accounting for this investment as the carrying value of our investment is zero. We do, however, receive income from dividend distributions on our investment.  Our investment in Origen had a market value of approximately $7.0 million based on a quoted market closing price of $1.40 per share from the “Pink Sheet Electronic OTC Trading System” as of June 29, 2012.

The unaudited revenue and expense amounts in the table below represent actual results through May 2012 and budgeted June 2012 results.

Stockholders' Equity Note [Abstract]

Equity Transactions

Equity Transactions

In November 2004, our Board of Directors authorized us to repurchase up to 1,000,000 shares of our common stock.  We have 400,000 common shares remaining in the repurchase program.  No common shares were repurchased during 2012 or 2011.  There is no expiration date specified for the buyback program.

Common OP Unit holders can convert their Common OP units into an equivalent number of shares of common stock at any time.  During the six months ended June 30,2012 and 2011, holders of Common OP Units converted 2,000 and 10,249 units, respectively to common stock.

On May 10, 2012 pursuant to a shelf registration statement on Form S-3, we registered with the SEC the sale of our common stock, preferred stock, debt securities, warrants and units consisting of two or more of the aforementioned securities. This shelf registration statement was effective upon filing and replaced our previous shelf registration statement which was scheduled to expire in May 2012.

On May 10, 2012 we entered into an "at-the-market" sales agreement with BMO Capital Markets Corp and Liquidnet Inc. to issue and sell shares of common stock from time to time. The current authorization allows for the sale of our common stock up to an aggregate amount of $100 million. There were no shares of common stock sold through June 30, 2012.

In January 2012, we closed an underwritten registered public offering of 4,600,000 shares of common stock at a price of $35.50 per share. The net proceeds from the offering were $156.0 million after deducting the underwriting discounts and expenses related to the offering. We used the net proceeds of the offering to repay $123.5 million of outstanding debt and we used $25.0 million to fund a portion of the Additional Florida Properties (See Note 2 for additional information), which were subsequently encumbered with a loan of $19.0 million. We expect to use any remaining net proceeds of the offering to fund possible future acquisitions of properties and for working capital and general corporate purposes.

Under our previous shelf registration statement on Form S-3 we had an "at-the-market" sales agreement to issue and sell shares

9.      Equity Transactions, continued

of common stock from time to time. We issued 40,524 shares of common stock from January 1, 2012 through May 9, 2012, when the sales agreement was terminated.  The shares of common stock were sold at the prevailing market price of our common stock at the time of each sale with a weighted average sale price of $37.22 and we received net proceeds of approximately $1.5 million.  The proceeds were used to pay down our line of credit.

On August 6, 2010, we entered into a Common Stock Purchase Agreement (the “Purchase Agreement”) with REIT Opportunity, Ltd. (“REIT Ltd.”), which provides that, upon the terms and subject to the conditions set forth in the Purchase Agreement, REIT Ltd. is committed to purchase up to the lesser of $100 million of our common stock, or 3,889,493 shares of our common stock, which is equal to one share less than twenty percent of our issued and outstanding shares of common stock on the effective date of the Purchase Agreement.  From time to time over the two year term of the Purchase Agreement, and at our sole discretion, we may present REIT Ltd. with draw down notices to purchase our common stock.  Any and all issuances of shares of common stock

to REIT Ltd. pursuant to the Purchase Agreement will be registered on our effective shelf registration statement on Form S-3.  In January, 2011 we sold 915,827 shares of common stock at a weighted average sale price of $32.76 and received net proceeds of $30.0 million.  The funds were used to pay down our line of credit.

In June 2011, we issued $45.5 million of Series A-1 preferred operating partnership (“A-1 preferred OP”) units as a result of the Kentland acquisition (see Note 2 for details).  A-1 preferred OP unit holders can convert the A-1 preferred OP units into shares of common stock at any time after December 31, 2013 based on a conversion price of $41 per share with $100 par value.  These A-1 preferred OP units are convertible, but not redeemable.  The A-1 preferred OP unit holders receive a preferred return of 5.1% until June 23, 2013 and 6.0% thereafter.

In August 2011, we discovered that we did not register with the SEC shares of our common stock purchased in the open market by our 401(k) plan for the benefit of participants in the plan.  We eliminated the option to purchase our common stock in the plan in September 2011 and the last purchase made through the plan was on September 16, 2011. As disclosed in our prior SEC filings, we considered filing a registration statement on Form S-3 offering to rescind the purchase of shares of our common stock by persons who acquired such shares through our 401(k) plan from September 16, 2010 through September 16, 2011. During that period, the plan purchased a total of 3,301 shares of our common stock for the benefit of a total of 85 participants. If a rescission offer were conducted, we would offer to repurchase shares of our common stock purchased through the 401(k) plan during the one year period ended September 16, 2011, but only if such shares either (i) were subsequently sold at a loss, or (ii) were purchased at a price higher than the market price of our common stock at the end of the rescission offer period, and are still held by the plan participant. To the best of our knowledge no shares purchased during the applicable period have subsequently been sold at a loss. Based on the recent and current market price of our common stock, we believe our potential liability, if any, with respect to shares of our common stock purchased during the applicable period and still held by plan participants is not material to us. In fact, if we were to conduct a rescission offer today, we do not believe we would have any liability unless the market price of our common stock at the end of the rescission offer period were less than $39.28 per share, which is the highest price paid for purchases of shares by plan participants during the applicable period. Based on these facts and given the expense of conducting a rescission offer, we have determined not to conduct a rescission offer.

Cash dividends of $0.63 per share were declared for the quarter ended June 30, 2012. On July 20, 2012 cash payments of approximately $18.0 million for aggregate dividends, distributions and dividend equivalents were made to common stockholders, common OP unitholders, and restricted stockholders of record as of July 10, 2012.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

We have elected to be taxed as a real estate investment trust (“REIT”) as defined under Section 856(c) of the Internal Revenue Code of 1986 (“Code”), as amended. In order for us to qualify as a REIT, at least ninety-five percent (95%) of our gross income in any year must be derived from qualifying sources. In addition, a REIT must distribute at least ninety percent (90%) of its REIT ordinary taxable income to its stockholders.

Qualification as a REIT involves the satisfaction of numerous requirements (some on an annual and quarterly basis) established under highly technical and complex Code provisions for which there are only limited judicial or administrative interpretations, and involves the determination of various factual matters and circumstances not entirely within our control. In addition, frequent changes occur in the area of REIT taxation which requires us to continually monitor our tax status. We analyzed the various REIT tests and confirmed that we continued to qualify as a REIT for the quarter ended June 30, 2012.

As a REIT, we generally will not be subject to U.S. federal income taxes at the corporate level on the ordinary taxable income we distribute to our stockholders as dividends. If we fail to qualify as a REIT in any taxable year, our taxable income could be subject to U.S. federal income tax at regular corporate rates (including any applicable alternative minimum tax). Even if we qualify as a REIT, we may be subject to certain state and local income taxes and to U.S. federal income and excise taxes on our undistributed income.

SHS, our taxable REIT subsidiary, is subject to U.S. federal income taxes. Our deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced, if necessary, by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence. Our temporary differences primarily relate to net operating loss carryforwards and depreciation. A federal deferred tax asset of $1.0 million is included in other assets in our Consolidated Balance Sheets as of June 30, 2012 and December 31, 2011.

We had no unrecognized tax benefits as of June 30, 2012 and 2011. We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of June 30, 2012.

We classify certain state taxes as income taxes for financial reporting purposes.  We record Texas Margin Tax as income taxes in our financial statements. In 2011 we were also subject to Michigan Business Tax that was replaced in May 2011 by a Corporate Income Tax. We believe that we will not have any corporate income tax liability under the new law. We recorded a provision for state income taxes of approximately $0.1 million for the six months ended June 30,2012 and a benefit of approximately $0.1 million for the six months ended June 30,2011.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments And Hedging Activities

Derivative Instruments and Hedging Activities

Our objective in using interest rate derivatives is to manage exposure to interest rate movements thereby minimizing the effect of interest rate changes and the effect it could have on future cash flows. Interest rate swaps and caps are used to accomplish this objective. We require hedging derivative instruments to be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract.

As of June 30, 2012, we had four derivative contracts consisting of two interest rate swap agreements with a total notional amount of $45.0 million and two interest rate cap agreements with a notional amount of $162.4 million. We generally employ derivative instruments that effectively convert a portion of our variable rate debt to fixed rate debt and to cap the maximum interest rate on certain variable rate borrowings. We do not enter into derivative instruments for speculative purposes.

13.Derivative Instruments and Hedging Activities, continued

The following table provides the terms of our interestrate derivative contracts that were in effect as of June 30, 2012:

Type	Purpose	Effective Date	Maturity Date	Notional  (in millions)	Based on	Variable Rate	Fixed Rate	Spread	Effective Fixed Rate
Swap	Floating to Fixed Rate	9/1/2002	7/1/2012	25.0	3 Month LIBOR	0.4682%	4.7000%	1.8700%	6.5700%
Swap	Floating to Fixed Rate	1/1/2009	1/1/2014	20.0	3 Month LIBOR	0.4682%	2.1450%	1.8700%	4.0150%
Cap	Cap Floating Rate	4/1/2012	4/1/2015	152.4	3 Month LIBOR	0.4600%	11.2650%	—%	N/A
Cap	Cap Floating Rate	10/3/2011	10/3/2016	10.0	3 Month LIBOR	0.4600%	11.0200%	—%	N/A

Subsequent to June 30, 2012 the $25.0 million interest swap described in the above table matured and was not replaced.

Generally, our financial derivative instruments are designated and qualify as cash flow hedges and the effective portion of the gain or loss on such hedges are reported as a component of accumulated other comprehensive income (loss) in our Consolidated Balance Sheets. To the extent that the hedging relationship is not effective or do not qualify as a cash flow hedge, the ineffective portion is recorded in interest expense. Hedges that received designated hedge accounting treatment are evaluated for effectiveness at the time that they are designated as well as through the hedging period.

In accordance with ASC Topic 815, Derivatives and Hedging, we have recorded the fair value of our derivative instruments designated as cash flow hedges on the balance sheet. See Note 16 for information on the determination of fair value for the derivative instruments.  The following table summarizes the fair value of derivative instruments included in our Consolidated Balance Sheets as of June 30, 2012 and December 31, 2011 (in thousands):

	Asset Derivatives					Liability Derivatives
	Balance Sheet Location	Fair Value				Balance Sheet Location	Fair Value
Derivatives designated as hedging instruments		June 30, 2012		December 31, 2011			June 30, 2012	December 31, 2011
Interest rate swaps and cap agreement	Other assets	$	—	$	—	Other liabilities	503	1,106
Total derivatives designated as hedging instruments		$	—	$	—		503	1,106

These valuation adjustments will only be realized under certain situations. For example, if we terminate the swaps prior to maturity or if the derivatives fail to qualify for hedge accounting, we would need to amortize amounts currently included in other comprehensive income (loss) into interest expense over the terms of the derivative contracts.  We do not intend to terminate the swaps prior to maturity and, therefore, the net of valuation adjustments through the various maturity dates will approximate zero, unless the derivatives fail to qualify for hedge accounting.

Our hedges were highly effective and had minimal effect on income.  The following table summarizes the impact of derivative instruments for the six months ended June 30,2012 and 2011 as recorded in the Consolidated Statements of Operations (in thousands):

Derivatives in cash flow hedging	Amount of Gain or (Loss) Recognized in OCI (Effective Portion)				Location of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)	Amount of Gain or (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)				Location of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)	Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)

13.Derivative Instruments and Hedging Activities, continued

Certain of our derivative instruments contain provisions that require us to provide ongoing collateralization on derivative instruments in a liability position.  As of June 30, 2012 and December 31, 2011, we had collateral deposits recorded in other assets of approximately $2.0 million and $3.1 million, respectively.
