Disposal Groups, Including Discontinued Operations, Disclosure [Text Block] | 10. Impairment of long-lived assets On March 31, 2025 the Company determined that its long-lived asset group related to 10 West 65th Street met the qualifications for an asset held for sale by determining that the sale of 10 West 65th Street was probable in addition to the other five criteria previously met. That determination was based on indications that the Company received that it was probable that a purchaser was prepared to purchase 10 West 65th Street at a price the Company would be willing to transact. Long-lived assets classified as held for sale are measured at the lower of its carrying amount or fair-value less costs to sell. As such, the Company recorded an impairment of the asset held for sale of $33,780 on the Company’s consolidated statement of operations for the six months ended June 30, 2025 and in the residential segment in the Company’s segment reporting (see footnote 9), based on the estimated selling price of $45,500 less carrying costs in investment in real estate, net, and estimated selling costs expected at the time of the sale. See footnote 1 for details of the completion of transaction to dispose of the long-lived assets.
