The optimal play is stealth density: primary + ADU + JADU using ADU pathways, as SB 9 is legally blocked. Ground-up expansion on this massive rural lot faces severe headwind blockers, including high fire severity, flood zones, and liquefaction soils.

ADU Potential
Flag / irregular · Corner lot · ~416 ft frontage × 611 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.
Seller Motivation
Inferred from days on market and listing-description language (e.g. "as-is", "estate sale", "motivated seller"). A screening heuristic for likely negotiability, not a statement about the seller's circumstances.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Median of 12 recent single-family sales in San Jose (95120): $964/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 25% of the 1,900 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.
