The price stands 84% above the island-wide basis, which does not control for location where values vary up to 5x. A rapid interior turnaround carries immense risk unless the specific location justifies this steep premium, inferred from pricing and time on market rather than from any inspection.

Proforma ROI Calculator
Back-of-the-napkin deal analysis across development strategies.
Median of 4 recent condo sales in Nantucket (02554): $359/sqft, plus 5% because new houses sold at a median 1.07x their comps across 239 real rebuilds. Sized within 50% of the 3,600 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.
Interest on the purchase price for the whole project plus half the build budget, since construction draws ramp up. The default is 7% over 33 months, the median purchase-to-sale time of 239 real Peninsula and South Bay rebuilds. Set the rate to 0 for a cash purchase, or use your own lender's terms.
