Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The Company has an indemnity obligation to Vornado Realty Trust, one of its significant shareholders, with respect to actions by the Company that affect Vornado Realty Trust's status as a REIT. All related party acquisitions, sales and loans were approved by the independent members of the Company's Board of Trustees or the Audit Committee. The Company leases certain properties to entities in which Vornado Realty Trust, a significant shareholder, has an interest. During 2015, 2014 and 2013, the Company recognized $255, $255 and $744, respectively, in rental revenue, including discontinued operations, from these properties. The Company leases its corporate office from an affiliate of Vornado Realty Trust. Rent expense for this property was $1,323, $1,252 and $1,225 in 2015, 2014 and 2013, respectively. In connection with efforts, on a non-binding basis, to procure non-recourse mezzanine financing from an affiliate of the Company's Chairman, pursuant to the terms of the EB-5 visa program administered by the United States Citizenship and Immigration Services (“USCIS”), for a joint venture investment in Houston, Texas, in which the Company has an investment, the Company executed a guaranty in favor of an affiliate of its Chairman. The guaranty provides that the Company will reimburse investors providing the funds for such financing if the following occurs: (1) the joint venture receives such funds, (2) the USCIS denies the financing solely because the project is not permitted under the EB-5 visa program, and (3) the joint venture fails to return such funds. As of December 31, 2015, the joint venture has not received any such funds and the Company has not recorded any liability as it relates to this guaranty. The maximum amount of funds that would be subject to the guaranty obligation is $18,000. In addition, in connection with efforts, on a non-binding basis, to procure non-recourse mezzanine financing from an affiliate of the Company's Chairman, pursuant to the terms of the EB-5 visa program administered by the USCIS, for an investment in Charlotte, North Carolina, the Company agreed to reimburse the Chairman's affiliate up to approximately $7 for its expenses.
