AddressIntel AI Briefing

High entry pricing relative to the size-matched ARV of $4.24M makes a teardown-and-mansionize strategy financially unviable. The optimal play here is a stealth density model using primary + ADU + JADU to generate rental income, though liquefaction risks will demand careful site engineering.

Proforma ROI Calculator

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

Zoning allows roughly 3,520 sqft on this lot, and the default builds to that envelope. The FAR figure is a discretionary-review trigger, not a hard cap.

Median of 12 recent single-family sales in Redwood City (94062): $1,247/sqft. Sized within 25% of the 3,500 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.
