The optimal play is stealth density: primary + ADU + JADU, utilizing the existing high-end remodeled structure to save on upfront construction costs. Ground-up redevelopment faces minor headwinds due to liquefaction soil hazards which could drive up engineering and foundation costs. High average sale-to-list ratios in the neighborhood confirm strong consumer demand.

Proforma ROI Calculator

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

Zoning allows roughly 5,689 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 5 recent single-family sales in Burlingame (94010): $1,365/sqft. Sized within 25% of the 5,700 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.
