An SB 9 lot split into multiple units represents the optimal strategy on this 9,583 sqft lot, which has plenty of room to double density. The absence of any environmental hazard zones makes this a straightforward, ministerial subdivision play with low execution risk. Mountain View's strong tech demographic supports premium exit prices for modern, subdivided units.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Zoning allows roughly 3,873 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 7 recent single-family sales in Mountain View (94041): $1,311/sqft. Sized within 25% of the 3,900 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.
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.
