AddressIntel AI Briefing
The optimal play here is an SB 9 lot split into multiple units to maximize the underutilized 9,583 sqft lot, as standard mansionization is financially unfeasible at this asking price. While the strong $250k median income demographic increases the ARV ceiling, the massive initial acquisition cost presents a severe barrier to development profitability.

ADU Potential
Flag / irregular · Corner lot · ~128 ft frontage × 142 ft deep, a tucked-away rear unit is very private; access is typically via the pole driveway. A second street frontage lets an ADU take its own entrance and address.
Screening heuristic based on lot size, existing coverage, lot orientation, and hazard overlays. CA ADU law is ministerial statewide; verify max size, setbacks, and JADU owner-occupancy with the local planning dept.
Redevelopment Potential
Small, older home using a low share of the allowable building envelope on a sizable lot, a scrape-and-rebuild or major-expansion play. Zoning allows roughly 4,312 sqft of gross floor area on this lot.

Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 4,312 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 3 recent single-family sales in San Jose (95129): $1,189/sqft. Sized within 25% of the 4,300 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
