Office Tower Acquisition Lands Lone Star in San Francisco

Credit Bid Enables Takeover

Lone Star Funds has taken control of 600 California Street, a prominent San Francisco office tower, after the property failed to attract external bidders at auction, reports IPE Real Assets. The 360 KSF building was acquired through a $216M credit bid, leveraging the mortgage Lone Star purchased earlier in the year for about $130M.

Sharp Valuation Drop

The office tower’s latest acquisition price of $361 PSF marks a notable decline from its last peak valuation of $900 PSF in 2019, when WeWork Capital Advisors secured the asset. Recent appraisals suggest the tower is now worth $109M, underscoring ongoing challenges in the San Francisco office market.

Vacancy and Next Steps

600 California is now largely vacant after WeWork, the previous anchor tenant, gave up its nearly 200 KSF footprint. Lone Star leadership indicated plans to reposition the building for a recovering market, aiming to boost both occupancy and asset value.

Why It Matters

This office tower acquisition reflects broader trends in urban office asset values and lender-driven takeovers during prolonged vacancy periods. Similar situations are playing out across distressed office portfolios, where creditors are increasingly stepping in to assume control as owners struggle to stabilize occupancy. Observers see Lone Star’s move as both a tactical recovery play and an indicator of shifting investor strategy in a volatile office sector.
