AddressIntel AI Briefing
This property presents a challenging layout with unreliable assessor square footage and low owner-occupancy rates in the immediate block. Attempting a teardown-and-mansionize or multi-unit strategy is heavily restricted because SB 9 is not applicable and ADU pathways are blocked. Investors should focus on a traditional interior value-add renovation rather than ground-up development.

Back-of-the-napkin deal analysis across development strategies.
Median of 3 recent multi-family sales in San Mateo (94401): $438/sqft. Sized within 25% of the 5,100 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.
