AddressIntel AI Briefing
This San Carlos condo unit represents a premium-priced investment with a significant markup over the local market average. With only one unit available in the building, a bulk-purchase angle is unavailable, making this a pure individual play. Strong rental yields are possible, but investors must weigh the high entry cost against the solid neighborhood appreciation.

Back-of-the-napkin deal analysis across development strategies.
Median of 12 recent condo sales in San Carlos (94070): $953/sqft. Sized within 50% of the 2,200 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.
