Summary
Lone Star Funds has emerged as the buyer for 600 California Street, a prominent San Francisco office tower that represents WeWork's only direct real estate acquisition. The transaction, expected to close at approximately $122 million according to November 26, 2025 reporting, underscores the extended distress affecting San Francisco's office sector and the significant depreciation of high-profile commercial assets acquired during the pre-pandemic real estate cycle.
The tower's acquisition history reveals the trajectory of WeWork's real estate strategy and subsequent market deterioration. The property was originally purchased in 2019 by a venture between WeWork and Rhone Advisors for approximately $323 million. The venture subsequently defaulted on a $240 million loan secured by the building in spring 2023, initiating a foreclosure process that placed the asset on the market. The property underwent an auction process that failed to attract competing bids, ultimately resulting in Lone Star Funds acquiring the tower at a substantial discount to its original purchase price—a loss reflecting the compressed valuations and limited institutional appetite for San Francisco office properties during the extended downtown office market downturn.
The transaction represents one of the few instances of institutional capital acquiring premium San Francisco office assets since the pandemic-driven collapse of downtown occupancy. Lone Star Funds' acquisition suggests potential stabilization in valuations for distressed trophy properties and indicates that select private equity firms are beginning to redeploy capital into San Francisco's office market at deeply discounted entry points. The $122 million purchase price—reflecting a 62% reduction from the 2019 entry valuation—illustrates both the severity of San Francisco's office market decline and the significant value destruction experienced by earlier investors in the sector.
