6. Investments in Unconsolidated Entities and International Investments Real Estate Joint Ventures and Investments

Joint ventures are common in the real estate industry. We use joint ventures to finance properties, develop new properties and diversify our risk in a particular property or portfolio of properties. As discussed in Note 2, we held joint venture interests in 88 properties as of December 31, 2025 and 79 properties as of December 31, 2024. Certain of our joint venture properties are subject to various rights of first refusal, buy-sell provisions, put and call rights, or other sale or marketing rights for partners which are customary in real estate joint venture agreements and the industry. We and our partners in these joint ventures may initiate these provisions (subject to any applicable lock up or similar restrictions), which may result in either the sale of our interest or the use of available cash or borrowings, or the use of limited partnership interests in the Operating Partnership, to acquire the joint venture interest from our partner. We may provide financing to joint venture properties primarily in the form of interest bearing loans. As of December 31, 2025 and 2024, we had construction loans and other advances to these related parties totaling $48.3 million and $59.6 million, respectively, which are included in deferred costs and other assets in the accompanying consolidated balance sheets. During the fourth quarter of 2025, we recorded a non-cash gain of $21.6 million related to the disposition of one unconsolidated property in satisfaction of its $84.3 million non-recourse mortgage loan, which is included in (Loss) gain on acquisition of controlling interest, sale or disposal of, or recovery on, assets and interests in unconsolidated entities and
