AddressIntel AI Briefing
The optimal strategy here is a teardown-and-mansionize play to maximize the potential of this sprawling 37,291 square foot parcel. Liquefaction acts as a slight engineering blocker, but the massive scale and extreme neighborhood values support heavy foundation remediation. Underutilized lot coverage of just 7% positions this as a prime candidate for an ultra-luxury estate.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 9,323 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 Hillsborough (94010): $1,322/sqft. Sized within 25% of the 9,300 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.
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.
Projected Profit
Warning: Margin is tight for the construction risk.
