Delray Beach calibration

Calibrated on 83 Delray Beach deals. With these build costs the calculator's land budget is a median 98% of what the builders actually paid for the lot, and within 25% of it on 47 of the 83 (the old defaults came to 85%).

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.
