AddressIntel AI Briefing
This massive 73,804 square foot hillside lot offers a spectacular canvas for a luxury teardown-and-mansionize project. Developers can build an monumental estate overlooking the valley, though complex hillside grading permits are expected. The massive gap between the entry price and estate-sized comps justifies the intensive site prep.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Median of 12 recent single-family sales in San Jose (95132): $992/sqft. No size-matched sales in San Jose, 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.
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.
