The complete guide
Buying on Nantucket is different. Here's everything that matters.
Limited inventory, historic restrictions, septic rules, and a fast-moving second-home market. This guide decodes it — so your purchase makes sense emotionally, financially, and logistically.
What you need to know
01
Financing on-island
Island lending has its own rules — appraisal timelines, insurance requirements, and lenders who actually know Nantucket. The wrong mainland lender can cost you the deal.
02
Title 5 septic
Massachusetts septic law shapes what a property can become. Bedroom counts, upgrade obligations, and inspection timing all hinge on it — and surprises here are expensive.
03
The Historic District
The HDC governs exterior changes across much of the island. It protects value, but renovation plans need to be drawn with its rules in mind from day one.
04
Flood zones & insurance
FEMA mapping, elevation certificates, and coastal exposure determine insurability and cost. Some of the island's most beautiful streets carry its most complex policies.
05
Timing & seasonality
Spring and summer bring competition; winter brings leverage. Knowing when to move matters as much as knowing where to look.
06
Off-market access
A meaningful share of the island trades without ever being listed. Relationships open those doors — this is where a sixth-generation network earns its keep.
