Nantucket vs. Cape Cod: the bridge changes everything
Key facts
- The 2025 median single-family sale: about $3.3 million on Nantucket, $790,000 on Cape Cod — roughly a four-to-one gap at the middle of each market.
- Scale is inverted: Cape Cod closed 3,507 home sales in 2025 across fifteen towns; Nantucket closed 419 transactions of every kind on one island.
- You can drive onto Cape Cod. Nantucket takes a one-hour fast ferry, a 2¼-hour car ferry, or a flight — and only the Steamship Authority carries vehicles.
- Nantucket's FY2026 residential tax rate is $3.12 per $1,000, among the lowest in Massachusetts; Cape towns set their own rates, most meaningfully higher.
Two ways to reach the beach
Buyers weighing the island against the Cape are rarely comparing houses. They are comparing relationships with the mainland. Cape Cod is continuous with it: you cross the canal, traffic and all, and you are there — same commute logic, same errands, same option to leave at nine o'clock on a whim.
Nantucket severs that. Everything and everyone arrives by boat or plane, which filters the market on both sides of every transaction. This page lays out what that difference does to prices, inventory, seasons, and the ownership experience — with each market's own 2025 numbers.
What the bridge does to a market
A bridge means supply. Cape Cod runs some fifteen towns deep, from Bourne to Provincetown, and closed over three and a half thousand home sales in 2025. When demand rises, buyers spread along Route 6A and Route 28 until they find their price. That breadth is why the Cape's median moved from $765,000 to $790,000 in a year — real appreciation, mainland pace.
No bridge means a fixed edge. Nantucket cannot annex a neighboring town, and roughly half the island is conservation land that will never be built on. Four hundred-odd transactions a year is the whole market. Scarcity is not a marketing line here; it is the zoning map.
The markets, side by side
| Nantucket (2025) | Cape Cod (2025) | |
|---|---|---|
| Median single-family sale | $3.3M | $790,000 |
| Sales closed | 419 (all property types) | 3,507 (single-family + condos) |
| Of asking price | 95.4% (of last ask, all types) | 95.2% (of original list) |
What those numbers actually mean
The four-to-one median gap is not a verdict on value — it is two different products. A $790,000 Cape house is a house; the mainland remains attached. A $3.3 million Nantucket house buys the house plus the moat: a protected harbor town, a historic district that never got paved into strip malls, and membership in a market where the middle of the range would be the trophy tier almost anywhere else in New England.
Note what the near-identical ask percentages say: both markets cleared 2025 at about 95% of asking. Neither is distressed and neither is frenzied. The difference is not negotiating temperature — it is altitude.
Access, honestly told
Cape access is a car. Nantucket access is a schedule: high-speed passenger ferries make Hyannis in about an hour, the Steamship Authority's traditional boat carries vehicles in about two and a quarter, and both lines run all year. Flights connect the island to Boston, New York, and beyond, swelling to a long list of nonstops in summer.
Owners learn the rhythm quickly — which boat to trust in a blow, when the car reservation matters, when to fly. It is genuinely a constraint. It is also the tollgate that keeps August from looking like a mainland beach town, and most owners come to see it that way. The full logistics live in the getting to Nantucket guide.
The carrying-cost surprise
Taxes run opposite to prices. Nantucket's FY2026 residential rate is $3.12 per $1,000 of assessed value — among the lowest in Massachusetts, because an enormous seasonal tax base shares the cost of a small year-round town. Cape towns set their own rates, and most sit meaningfully higher; the same million dollars of assessed value generally carries a larger tax bill on the mainland side of the Sound.
The island claws some of that back elsewhere — the 2% Land Bank fee on most purchases, ferry logistics on every trade job, and insurance priced for thirty miles of Atlantic exposure. The honest math lives in the cost of ownership guide, and year-round residents should read the residential exemption guide before comparing bills.
The honest paragraph
If weekly access from a mainland life is the requirement — aging parents nearby, a business that needs you, kids whose seasons don't bend — the Cape is the rational answer, and there is nothing lesser about it. Plenty of wonderful lives run over that bridge.
But the two are not interchangeable at different price points. The Cape is the mainland at the beach. Nantucket is somewhere else entirely, and the boat ride is the border. Buyers who want the island want that border. It is the most expensive thing about the place, and it is also the point. Weighing the other island instead?
