Nantucket condos: the island's smallest market, explained
Four sales, not four hundred
Ask what a condo costs on Nantucket and you have asked a genuinely difficult statistical question — not because the answer is secret, but because the sample is tiny. In the first half of 2026, the island recorded four condo sales. Not four hundred: four, out of 111 total sales island-wide.
That thinness is the single most important fact about this market, and it cuts both ways. For buyers, condos are the island's most accessible door: the recent median trades sit around half the island's single-family median. For sellers and buyers alike, a market this small moves in lumps — one quarter's "trend" is two closings. Here is how to read it, and how to buy in it well.
What a Nantucket condo actually is
Why buyers choose them
Price of entry. Recent condo trades have a median around $1.25 million against a single-family median north of $2.8 million. "Affordable" is relative on this island, but the gap is real: a condo is how a first foothold on Nantucket most often actually happens.
Lock-and-leave. The association handles the envelope, the grounds, the winter. For an owner who is here eight weeks a year, that is not a small amenity — it is the difference between a house that needs a caretaker and a door that just opens in June. The vacation-homes page covers that ownership pattern honestly.
Walkability. The in-town stock puts you inside the downtown life — restaurants, the wharves, the ferry — without a car and without a lawn.
The master deed is the property
Here is the sentence to carry out of this page: when you buy a condo, the documents are the property. The master deed and bylaws decide what you may actually do with your unit — and on Nantucket the highest-stakes clause is rentals.
Short-term rentals are now legal by right under town zoning — but a master deed that prohibits rentals under 31 days overrides your town registration entirely. The private restriction wins. Associations also commonly set minimum rental periods, annual rental counts, pet rules, and renovation approval paths. None of this is a flaw — restrictive documents often protect exactly the quiet an owner is buying — but it must match your plan. The short-term rental guide covers the town side; the deed covers yours.
Read the documents before the offer. On a thin-inventory island there is pressure to move fast; this is the corner not to cut.

Nantucket condos — frequently asked questions
Are there actually condos on Nantucket?
Yes — but few, and few trade: four sales in the first half of 2026, out of 111 island-wide. Most are converted in-town houses or small mid-island clusters rather than anything resembling a mainland complex.How much does a Nantucket condo cost?
Recent trades put the median around $1.25 million — roughly half the island's single-family median — with a wide range around it. In a market this small, medians move on two or three closings, so treat any single quarter's number as a reading, not a law.Can I rent out my condo short-term?
Only if the master deed allows it. Town zoning now permits short-term rentals by right, but a private deed restriction overrides town registration — the documents win. Check them before you offer, and see the short-term rental guide for the town-side rules.What does the condo fee cover?
Typically the master insurance, exterior and grounds upkeep, and reserves — the association's budget says exactly what. Read it, and the reserve study, as part of diligence; the fee's size matters less than whether it is honest.Are Nantucket condos a good investment?
As an entry to a supply-constrained island market, the logic is real — and so are the constraints: thin resale liquidity and document-limited use. Buy one for what the deed lets you do with it, and let any income be the discount rather than the thesis.Where are the condos on Nantucket?
Mostly in and around Town — converted historic houses — and mid-island, where the island's small purpose-built clusters sit. Recent sales split along exactly those lines.Condo inventory here is a handful of doors
