Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates As of March 31, 2023, we have 25% and 50% ownership interests in BRE Ace LLC and 1776 Holding LLC, respectively, which are VIEs. We do not consolidate BRE Ace LLC and 1776 Holding LLC because we are not the primary beneficiary. For both VIEs, our investment interests are included in the condensed balance sheets as Investments in unconsolidated affiliates, and equity earned is included in the condensed statements of operations as Equity in earnings from unconsolidated affiliates.Our two unconsolidated affiliates have aggregated debt balances of $380 million and $393 million as of March 31, 2023 and December 31, 2022, respectively. The debt is secured by their assets and is without recourse to us. Our maximum exposure to loss as a result of our investment interests in the two unconsolidated affiliates is primarily limited to (i) the carrying amount of the investments, which totaled $75 million and $72 million as of March 31, 2023 and December 31, 2022, respectively, and (ii) receivables for commission and other fees earned under fee-for-service arrangements.
