San Francisco office investing is a high-conviction, long-cycle strategy in 2026, with the most credible opportunities concentrated in Mission Bay, Central SoMa, and select creative product in the Dogpatch where AI and life sciences tenants are actively leasing. Flight-to-quality is the dominant narrative, with tenants vacating older Embarcadero and Financial District commodity product in favor of modern, amenitized space with efficient floor plates and outdoor access. Value-add office plays targeting conversion to life sciences, residential, or hotel use are attracting distressed capital, though entitlement risk and conversion costs are significant barriers. Buyers underwriting office acquisitions at 60 to 70 cents on the dollar relative to 2019 values can pencil attractive going-in yields if they underwrite to realistic re-leasing timelines of 24 to 48 months and have the balance sheet to carry interim vacancy.
