Buildable Headroom+6,121 sqft

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 9,792 sqft of gross floor area on this lot.

Screening estimate comparing existing living area to the city's single-family floor-area limit. City sets no explicit FAR (or is not individually curated); allowable area is a conservative estimate. Source: conservative default (0.40 FAR — city not individually curated) (as of 2026-06-30). Verify FAR, coverage, setbacks, and height with the local planning dept.

Proforma ROI Calculator

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

We don't hold this jurisdiction's floor-area rule, so the default builds to roughly 9,792 sqft from a conservative 0.40 FAR approximation, a starting point and not a zoning answer. Check the local code before you rely on it.

Median of 8 recent single-family sales in Hillsborough (94010): $1,286/sqft. Sized within 25% of the 9,800 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.
