Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Financial Instruments Not Carried at Fair Value The following methods and assumptions were used to estimate the fair value of each class of financial instruments that are not recorded at fair value on the consolidated balance sheets: Cash and cash equivalents, restricted cash, accounts receivable (included in other assets), accounts payable and accrued liabilities: The carrying amounts reported in the balance sheets for these instruments approximate their fair value due to the short term nature of these accounts. Junior subordinated notes: At March 31, 2022 and December 31, 2021, the estimated fair value of the notes is lower than their carrying value by approximately $8,150,000 and $8,296,000, respectively, based on a market interest rate of 4.30% and 4.21%, respectively. Mortgages payable: At March 31, 2022, the estimated fair value of the Company’s mortgages payable is lower than their carrying value by approximately $36,739,000, assuming market interest rates between 3.92% and 4.67%. At December 31, 2021, the estimated fair value of the Company's mortgages payable was greater than their carrying value by approximately $511,000, assuming market interest rates between 3.12% and 3.87%. Market interest rates were determined using rates which the Company believes reflects institutional lender yield requirements at the balance sheet dates. Considerable judgment is necessary to interpret market data and develop estimated fair value. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value. Non-recurring fair value measurements The Company reviews each investment in real estate and joint venture interests when events or circumstances change, indicating the carrying value of the investment may not be recoverable. In the evaluation of an investment for impairment, many factors are considered, including estimated current and expected cash flows from the asset during the projected hold period, costs necessary to extend the life of the asset, expected capitalization rates, projected stabilized net operating income, and the ability to hold or dispose of the asset in the ordinary course of business.
