Debt Disclosure [Abstract]
Debt	Debt Senior Secured Revolving Credit Facility In 2013, we entered into an amended and restated $380 million senior secured revolving credit facility, or the Credit Facility, with a syndicate of major national banks. The Credit Facility has an accordion feature that allows us, assuming our compliance with applicable covenants and at the lenders’ discretion, to borrow up to $500 million thereunder if certain criteria are met. The amount available for us to borrow under the Credit Facility is subject to limitations governed by calculations based on the cost, value and debt yield supported by our properties that form the borrowing base of the Credit Facility. The credit agreement requires us to comply with various financial covenants as well as customary affirmative and negative covenants that restrict our ability to, among other things, incur debt and liens, make investments, dispose of properties and make distributions. The Credit Facility is secured by our ownership interest in American Residential Leasing Company, LLC, which is a wholly owned subsidiary of our Operating Partnership. The Credit Facility contains certain financial covenants, including a maximum leverage ratio, a minimum tangible net worth, a minimum fixed charge coverage ratio and a minimum liquidity. As of March 31, 2014, we were in compliance with all of the financial covenants of the Credit Facility. The Credit Facility matures in January 2015 and has an optional one-year extension (assuming our compliance with applicable covenants). Borrowings under the Credit Facility bear interest, at our option, at either the one-month, two-month, three-month or six-month Eurodollar rate or the base rate, plus, in each case, a spread based on a ratio of total indebtedness to total asset value (each as defined in the credit agreement that governs the Credit Facility) ranging from less than or equal to 45% to greater than 55%. The Eurodollar rate for an interest period is the London Interbank Offered Rate, or LIBOR, for a term equivalent to such period plus a spread ranging from 2.50% to 3.25% (determined as described in the preceding sentence) and the base rate for any day is a fluctuating rate per annum equal to the highest of (a) the Federal Funds Rate plus 0.50%, (b) Bank of America's "prime rate" for such day and (c) the one-month Eurodollar rate plus 1.00% plus a spread ranging from 1.50% to 2.25% (determined as described in the preceding sentence). We are also required to pay a quarterly fee on the unused portion of the Credit Facility at a rate of between 0.35% and 0.45% per annum, based on the actual daily unused balance during a fiscal quarter. For the three months ended March 31, 2014 and 2013, we incurred non-utilization fees of $0.2 million and $0.1 million, respectively. As of March 31, 2014, $303.0 million was outstanding under the Credit Facility, bearing weighted-average interest at a rate of 2.9%, with remaining availability of $32.3 million. We have incurred $5.1 million in financing costs in connection with the Credit Facility, which are included in deferred financing costs, net on the accompanying condensed consolidated balance sheets. These costs are being amortized to interest expense over the remaining initial term of the Credit Facility. Exchangeable Senior Notes In November 2013, we issued and sold $115.0 million aggregate principal amount of 3.25% Exchangeable Senior Notes due 2018 (the “Notes”). The Notes are senior unsecured obligations of the Operating Partnership and rank equally in right of payment with all other existing and future senior unsecured indebtedness of the Operating Partnership. Interest is payable in arrears on May 15 and November 15 of each year, beginning May 15, 2014, until the maturity date of November 15, 2018. The Operating Partnership’s obligations under the Notes are fully and unconditionally guaranteed by the Company. The Notes bear interest at a rate of 3.25% per annum and contain an exchange settlement feature, which provides that the Notes may, under certain circumstances, be exchangeable for cash, shares of Common Stock or a combination of cash and shares of Common Stock, at the option of the Operating Partnership, based on an initial exchange rate of 46.9423 shares of Common Stock per $1,000 principal amount of Notes, subject to adjustment of the exchange rate under certain circumstances. At the initial exchange rate, the Notes are exchangeable for Common Stock at an exchange price of approximately $21.30 per share of Common Stock, representing an approximately 22.5% premium over the last reported sale price of the Common Stock on November 21, 2013, which was $17.39 per share. Prior to the close of business on the business day immediately preceding August 15, 2018, the Notes will be exchangeable at the option of the holders only under the following circumstances: (1) during any calendar quarter beginning after December 31, 2013 (and only during such quarter) if the closing sale price per share of the Common Stock is more than 130% of the then-current exchange price for at least 20 trading days (whether or not consecutive) in the period of 30 consecutive trading days ending on the last trading day of the preceding calendar quarter; (2) during the five consecutive business-day period following any five consecutive trading-day period in which the trading price per $1,000 principal amount of Notes was less than 98% of the product of the closing sale price per share of the Common Stock multiplied by the then-current exchange rate; or (3) upon the occurrence of specified corporate transactions described in the Indenture. On or after August 15, 2018, the Notes will be exchangeable at any time prior to the close of business on the second business day immediately preceding the maturity date. Subject to its election to satisfy its exchange obligations entirely in shares of Common Stock, upon exchange, the Operating Partnership will pay or deliver, as the case may be, to exchanging holders in respect of each $1,000 principal amount of notes being exchanged a settlement amount either solely in cash, solely in shares or in a combination of cash and shares of Common Stock. The number of shares of Common Stock holders of Notes will receive upon exchange may be subject to an “exchange share cap” unless and until the Company obtains stockholder approval to issue more than 19.99% of the Common Stock outstanding at the time the Notes were issued (the “aggregate share cap”) upon exchange of the Notes in accordance with the listing standards of the New York Stock Exchange (the “NYSE”). The exchange share cap is equivalent to the pro rata portion of the aggregate share cap represented by the notes to be exchanged. Holders of the Notes will not have the right to receive more than 55.9206 shares of Common Stock per $1,000 principal amount of Notes, as adjusted for share splits and combinations, upon an exchange of the Notes. If the delivery of shares of Common Stock upon exchange of the Notes is subject to the exchange share cap, unless and until such stockholder approval is obtained, the Operating Partnership will be deemed to have elected “combination settlement” with a specified dollar amount per $1,000 principal amount of Notes of at least $1,000 for all Notes submitted for exchange, which means the Operating Partnership will be obligated to settle its exchange obligation by paying up to the specified dollar amount with respect to such Notes in cash and delivering shares of Common Stock for any exchange value in excess of such specified dollar amount (subject to the exchange share cap). The Company will not have any obligation to seek stockholder approval to issue shares of Common Stock in excess of these limitations. However, if any delivery of shares of Common Stock owed to a holder upon exchange of notes is not made, in whole or in part, as a result of the limitations described above, the Operating Partnership’s obligation to make such delivery will persist, and the Operating Partnership will deliver such shares to such holder as promptly as practicable following the earlier of the date on which the issuance of shares of Common Stock in excess of the limitations described above is approved by the Company’s stockholders or the aggregate share cap is no longer required under the listing standards of the NYSE. In connection with the issuance of the Notes, we recorded approximately $99.1 million within exchangeable senior notes on the accompanying condensed consolidated balance sheets, based on the fair value of the instrument using a straight-debt rate of 6.5% at the time of issuance, and approximately $15.4 million in additional paid-in-capital, net of $0.5 million in financing costs, in the accompanying condensed consolidated statement of equity. The difference between the $115.0 million face amount and the $99.1 million will be accreted over the five-year period ended November 15, 2018. As of March 31, 2014, the unaccreted discount was $15.0 million. We incurred $3.8 million in financing costs, of which $3.3 million are included in deferred financing costs, net on the accompanying condensed consolidated balance sheets to be amortized to interest expense over the term of the Notes.
