AddressIntel AI Briefing
An SB 9 lot split is completely blocked here, forcing developers to look at long-term holds or basic renovations. Active liquefaction hazards and high existing lot coverage further diminish redevelopment potential. The thin margin between asking price and projected ARV makes any major ground-up construction financially unviable.

Back-of-the-napkin deal analysis across development strategies.
Median of 5 recent multi-family sales in San Mateo (94401): $438/sqft. Sized within 50% of the 6,000 sqft build, because smaller houses sell for more per foot and pricing a rebuild off them overstates resale.
Commission, transfer tax and closing. Deducted from resale before profit, so the ROI below is net of the exit rather than gross.
Carry on total capital for the project duration. At 0% the model is a cash purchase; 12 months at a typical construction-loan rate moves ROI by 6 to 10 points on a deal this size, so price it with your real rate.
