Massachusetts's standard purchase process, at an extreme price point

Nantucket purchases follow standard Massachusetts contingency structures (inspection, financing, appraisal), but the island's competitive, high-end market often moves quickly, and all-cash offers are genuinely common.

Confirm coastal-erosion exposure directly, parcel by parcel

Given Nantucket's real, documented, currently-observable coastal erosion (some bluff-front properties have lost the large majority of their assessed value), confirm current FEMA flood-zone status and erosion risk directly for any specific target address before finalizing an offer.

Understand the real tax-rate-vs-bill mechanic

Nantucket's low effective property tax rate (~0.31%) still produces a substantial annual dollar bill given the island's extreme home values -- confirm the actual current millage and assessed value for a target property directly.
