Convertible Debt at Fair Value [Abstract]
Convertible Debt at Fair Value	NOTE 8: CONVERTIBLE DEBT AT FAIR VALUE As part of an agreement entered into on March 16, 2016 (the “Exchange Agreement”) with Real Estate Strategies, L.P. (“RES”, which also includes affiliated entities), the Company issued to RES a Convertible Promissory Note (the “2016 Note”), bearing interest at 6.25% per annum, in the principal amount of $1,012 initially convertible into shares of 6.25% Series D Cumulative Convertible Preferred Stock (“Series D Preferred Stock”), which could be subsequently converted into 97,269 shares of common stock. Following the conversion of all of the outstanding Series D Preferred Stock into common stock and the issuance of the Series E Preferred Stock on March 1, 2017, the 2016 Note was amended to be convertible directly into 97,269 shares of common stock at any time at the option of RES or automatically when the 6.25% Series E Cumulative Convertible Preferred Stock (“Series E Preferred Stock”) was required to be converted or is redeemed in whole (see Note 11). The 2016 Note was not convertible to the extent that a conversion would cause RES, together with its affiliates, to beneficially own more than 49% of the voting stock of the Company at the time of the conversion. Any conversion reduces the principal amount of the Note proportionally. On November 19, 2020, the Company entered into separate Convertible Promissory Notes and Loan Agreements (the “2020 Notes”) in favor of (a) SREP III Flight—Investco 2, L.P. (“SREP”), an affiliate of StepStone Group LP, for $7,220, and (b) Efanur S.A. (“Efanur”), an affiliate of IRSA Inversiones y Representaciones Sociedad Anónima, for $2,780. Pursuant to the 2020 Notes, the Company borrowed $10,000 from SREP and Efanur and used the proceeds to repay loans outstanding under the credit facility. Each of the 2020 Notes accrued interest at 10.00% per annum, provided for the interest rate to increase to 20% upon an Event of Default or if any amounts under the applicable Note are outstanding after May 31, 2021, provided for the capitalization of interest, and provided for the payment of all accrued and unpaid interest and principal on the maturity date. Each of the Notes also provided, subject to a Make Whole Fee (as defined in the respective Note) payable to SREP and Efanur, as applicable, for the interest rate to increase to 25% upon a determination by the disinterested members of the board of directors of the Company (a) not to proceed with, or to terminate, a Rights Offering, (b) to prohibit a Non-Rights Offering Conversion or (c) not to seek shareholder approval of the transactions contemplated by the Notes, including the issuance of shares of common stock of the Company and the conversion price, because the failure to make any such determination would reasonably be expected to constitute a breach of the directors’ duties under Maryland law. The Company made an irrevocable election to record these notes in its entirety at fair value utilizing the fair value option available under U.S. GAAP in order to more accurately reflect the economic value of the notes. As such, gains and losses on the notes are included in net gain (loss) on derivatives and convertible debt within net earnings (loss) each reporting period. Gains (losses) related to these notes were recognized totaling $5,863, ($5,795), and ($80) during the period from January 1 to December 1, 2021 and the years ended December 31, 2020 and 2019, respectively. The fair value of the 2016 Note was determined using a trinomial lattice-based model, which is a generally accepted computational model typically used for pricing options and is considered a Level 3 fair value measurement. The fair value of the 2020 Note was based on the value of the note upon conversion due to the high probability associated with that event. Interest expense related to these notes was recorded separately from other changes in its fair value within interest expense each period. Both the 2016 Note and the 2020 Notes were repaid in full on November 19, 2021 following the Portfolio Sale.
