Fort Lauderdale calibration

Calibrated on 148 Fort Lauderdale deals. With these build costs the calculator's land budget is a median 100% of what the builders actually paid for the lot, and within 25% of it on 87 of the 148 (the old defaults came to 41%).

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.
