AddressIntel AI Briefing

While the lot size is generous, the lack of SB 9 pathways and the presence of liquefaction hazards severely limit heavy redevelopment. The optimal play is a single-family remodel, though the entry price is prohibitive relative to the neighborhood's underlying values.

Proforma ROI Calculator

Back-of-the-napkin deal analysis across development strategies.

Median of 12 recent multi-family sales in San Mateo (94401): $566/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. No size-matched sales in San Mateo, so this median mixes build sizes and reads high for a large rebuild.

Commission, transfer tax and closing. Deducted from resale before profit, so the ROI below is net of the exit rather than gross.

Interest on the purchase price for the whole project plus half the build budget, since construction draws ramp up. The default is 7% over 33 months, the median purchase-to-sale time of 239 real Peninsula and South Bay rebuilds. Set the rate to 0 for a cash purchase, or use your own lender's terms.
