K-Shaped Divergence Intensifies: Luxury Frenzy vs. Affordable Housing Strain

Bay Area housing market shows extreme bifurcation: AI-driven luxury sales (Atherton $10M, Hillsborough $70M off-market) and rent boom (SF 1BR $4,180) while affordable housing nonprofits like EBALDC cut jobs and multifamily REITs face balance sheet distress (CMCT $502M debt, Oakland office default). Supply constraints persist with only 1,400 multifamily units delivered in SF. New data: SF metro median $948K (-4.2% YoY) but inventory down 16.3%. Larkspur's combined data masks a 60-day pricing cliff—two sales closed at 92% and 70% of list after 60 days. Latest overbids (08/14/2026): Diamond Heights 62% over, Outer Sunset 77% over, Seacliff $9.988M at 11% over—frenzy spreading beyond luxury enclaves.
