AddressIntel AI Briefing

The existing footprint already maximizes the lot's theoretical buildable footprint, rendering a full teardown impractical. The optimal play is stealth density via a cosmetic remodel of the primary home coupled with a JADU conversion to optimize passive rental yields. This allows developers to leverage the high sale-to-list ratio of the neighborhood with minimized capital risk.

Proforma ROI Calculator

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

Median of 3 recent multi-family sales in Millbrae (94030): $598/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 25% of the 3,300 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.

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.
