Build-and-sell pro formaBoca Raton calibration
Calibrated on 96 Boca Raton deals. With these build costs the calculator's land budget is a median 97% of what the builders actually paid for the lot, and within 25% of it on 39 of the 96 (the old defaults came to 94%).
A quick pro forma, not an appraisal. Every number is editable; the starting points come from city records, and build cost is an assumption to replace with a builder’s bid.
