Commitments and Contingencies [Abstract]
Commitments and Contingencies Disclosure [Text Block]	are frequently covered by insurance. If it has been determined that a loss is probable to occur, the estimated amount of the loss is accrued in the consolidated financial statements. While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material effect on the Company’s consolidated financial statements. Certain of the MF Properties own apartment properties that generated LIHTCs for the previous partners in these partnerships. In connection with the acquisition of partnership interests in these partnerships by subsidiaries of the Company, the Company has agreed to reimburse the prior partners for any liabilities they incur due to recapture of these tax credits to the extent the recapture liability is due to the operation of the properties in a manner inconsistent with the laws and regulations relating to such tax credits after the date of acquisition. No amount has been accrued for this contingent liability because management believes that the likelihood of any payments being required there under is remote. In October 2012, the limited partnership that owns the Greens Property admitted two entities that are affiliates of BC Partners as new limited partners as part of a syndication of LIHTCs on the Greens Property. At closing, the BC Partners invested $961,000 of equity into this limited partnership and is obligated to invest another $2.2 million at contractual scheduled milestones tied to construction, the property reaching a specified debt service coverage ratio, the designation from the state of the tax credits, but the final payment will be received no earlier than October 1, 2013. In connection with this BC Partners transaction, the Company entered into guarantee agreements with the BC Partners under which the Company has guaranteed certain obligations of the general partner of the Greens of Pine Glen limited partnership, including an obligation to repurchase the interests of the BC Partners if certain “repurchase events” occur. A repurchase event is defined as any one of a number of events mainly focused on the completion of the property rehabilitation, property rent stabilization, the delivery of LIHTCs, tax credit recapture and foreclosure. No amount has been accrued for this contingent liability because the likelihood of a repurchase event is remote. The maximum exposure to the Company at March 31, 2013 under the guarantee provision of the repurchase clause is approximately $721,000 which represents 75% of the equity contributed by BC Partners. In connection with the Ohio Properties transaction in 2011, the Company entered into guarantee agreements with the BC Partners under which the Company has guaranteed certain obligations of the general partner of these limited partnerships, including an obligation to repurchase the interests of the BC Partners if certain “repurchase events” occur. A repurchase event is defined as any one of a number of events mainly focused on the completion of the property rehabilitation, property rent stabilization, the delivery of LIHTCs, tax credit recapture and foreclosure. Even if a repurchase event should occur, 25% of the BC equity would remain in the Ohio Properties and thus BC, a third party, would have sufficient equity in the Ohio Properties for the Company to recognize the sale discussed in Note 9. No amount has been accrued for this contingent liability because the likelihood of a repurchase event is remote. The maximum exposure to the Company at March 31, 2013 under the guarantee provision of the repurchase clause is approximately $4.9 million which represents 75% of the equity contributed by BC Partners. In March 2013, a wholly-owned subsidiary of the Company executed a 35-year ground lease with the University of Nebraska - Lincoln (“Lessor”) with an annual lease payment of $100. The leased property will have a mixed-use development consisting of a 1,605 stall parking garage and 475 bed student housing complex constructed on it. The Lessor will own the parking garage and the Company will own the student housing. The Company currently estimates the construction of the student housing will cost approximately $34.0 million and it executed a guaranteed maximum price contract with the general contractor for the construction. The lease agreement has a stipulation that if the parking garage is not completed by August 1, 2014, the Company will pay damages of $6,000 per day of delayed completion to the Lessor. The Company's construction contract with the general contractor also stipulates that the general contractor will pay the Company $6,000 per day of liquidated damages for each day subsequent to August 1, 2014 that the parking garage is not completed. Construction has commenced and is estimated to be completed before the August 1, 2014 deadline. To finance the construction of the student housing, the Company has executed an interest-only loan to borrow up to $25.5 million for a three year term at a variable interest rate. The Company also secured $4.3 million tax-incremental financing loan which is for a term of five years, carries a fixed interest rate of approximately 4.7%, requires principal payments commencing after 24 months and has a balloon payment due at maturity. These financings were executed in April 2013 and no amounts have been borrowed yet. As the holder of residual interests issued in connection with its TEBS and TOB bond financing arrangements, the Partnership is required to guarantee certain losses that can be incurred by the trusts created in connection with these financings. These guarantees may result from a downgrade in the investment rating of tax-exempt mortgage revenue bonds held by the trust or of the senior securities issued by the trust, a ratings downgrade of the liquidity provider for the trust, increases in short term interest rates beyond pre-set maximums, an inability to re-market the senior securities or an inability to obtain liquidity for the trust. In each of these cases, the trust will be collapsed. If the proceeds from the sale of the trust collateral are not sufficient to pay the principal amount of the senior securities with accrued interest and the other expenses of the trusts, the Partnership will be required to fund any such shortfall pursuant to its guarantee.
