Proforma ROI Calculator

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

Median of 12 recent townhome sales in San Carlos (94070): $970/sqft. Sized within 50% of the 3,200 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.
