Discontinued Operations and Disposal Groups [Abstract]
Property Dispositions	Property Dispositions We may decide to dispose of a property due to a variety of circumstances, including but not limited to, vacancy, tenants electing not to renew their leases, tenant insolvency, or lease rejection in the bankruptcy process. In such cases, we assess whether we can obtain the highest value from the property by selling it, as opposed to re-leasing it. We may also sell a property when we receive an unsolicited offer or negotiate a price for an investment that is consistent with our strategy for that investment. When it is appropriate to do so, we classify the property as an asset held for sale on our consolidated balance sheets. Our property dispositions are also discussed in Note 4 and Note 5. 2021 Real Estate — Land, Buildings and Improvements On October 29, 2021, we sold a retail facility in Zadar, Croatia, for total proceeds, net of selling costs, of $14.4 million, and recognized a net gain on this sale of $2.0 million (inclusive of $0.4 million attributable to a noncontrolling interest). In connection with this disposition, we repaid the $8.3 million non-recourse mortgage loan encumbering the property (Note 9). Amounts are based on the exchange rate of the euro on the date of the transaction. On December 29, 2021, we sold a vacant industrial facility located in Columbus, Georgia, for total proceeds, net of selling costs, of $0.5 million, and recognized a net loss on this sale of $0.8 million. In connection with this disposition, we prepaid the $6.8 million non-recourse mortgage loan encumbering this property (Note 9). Operating Real Estate — Land, Buildings and Improvements On September 3, 2021, we sold two student housing operating properties located in Cardiff and Portsmouth, United Kingdom, for total proceeds, net of selling costs, of $147.8 million (based on the exchange rate of the British pound sterling on the date of disposition) and recognized a net gain on these sales totaling $42.8 million (inclusive of $3.7 million attributable to a noncontrolling interest and income taxes totaling $0.4 million recognized upon sale). In connection with this disposition, we repaid the $83.3 million non-recourse mortgage loan encumbering the properties (Note 9). 2020 Real Estate — Land, Buildings and Improvements On July 22, 2020, our warehouse facility located in Freetown, Massachusetts, was disposed of through eminent domain. As a result, we received condemnation proceeds, net of selling costs, of $6.1 million, and recognized a gain on sale of real estate of $2.4 million. We repaid the $3.2 million non-recourse mortgage loan previously encumbering the property using the condemnation proceeds. 2019 Operating Real Estate — Land, Buildings and Improvements On January 29, 2019, we sold the 97% interest that we held in our last multi-family residential property, located in Fort Walton Beach, Florida, to one of our joint-venture partners for total proceeds, net of selling costs, of $13.1 million, and recognized a gain on sale of $15.4 million (which includes a $2.9 million gain attributable to noncontrolling interests). The buyer assumed the related non-recourse mortgage loan outstanding on this property totaling $24.2 million. Real Estate — Land, Buildings and Improvements During the year ended December 31, 2019, we sold the 11 properties in our United Kingdom trade counter portfolio for total proceeds, net of selling costs, of $39.3 million, and recognized an aggregate gain on sale of $10.3 million. At closing, we repaid the $22.7 million non-recourse mortgage loan encumbering these properties (amounts are based on the exchange rate of the British pound sterling at the date of sale).
