A seller asking $2 million gives up more of it than a seller asking $4 million does — and a seller asking $11 million gives up the most of all. The data says the safest price on Nantucket right now is the one everyone else is also asking.
The year so far, in two honest numbers
Nantucket’s 184 home sales through September 30, 2026 closed at a median of $3,700,000, up 12.1% from $3,300,000 over the same nine months last year. The average home sale climbed too, to $4,694,000, up 8.0% from $4,348,000. (Source: The Kalman Co. Market Report, September 2026 edition, LINK data through Sept. 30, 2026.)
I like seeing median and average move together. It means this year’s gains aren’t a handful of enormous water-view trades dragging the average up while the typical house sits flat — the middle of the market is genuinely worth more than it was a year ago, not just the top of it.
But “the market is up” hides more than it tells you. Break the same nine months down by what a house actually sold for against what it was asking, and a different story shows up — one that matters a lot more if you’re the one setting, or negotiating, a number.
Five tiers, one curve
LINK tracks this year’s home sales in five budget bands, from under $2 million to $10 million and up. Line up what each band actually captured of its final asking price, and you get a curve, not a flat line:
- Under $2 million: 25 sales (14% of the year’s home sales), capturing 91.3% of ask
- $2–3 million: 46 sales (25%), capturing 95.2%
- $3–5 million: 55 sales (30% — the single busiest tier), capturing 96.2%
- $5–10 million: 46 sales (25%), capturing 94.2%
- $10 million and up: 12 sales (7%), capturing 90.5%
(Source: The Kalman Co. Market Report, September 2026 edition, LINK data through Sept. 30, 2026.)
Rising, then falling. The $3–5 million tier — which also happens to be where the most houses actually traded this year — got the closest to its number. Both ends of the market gave up more.
Why the middle wins
It isn’t a coincidence that the busiest tier and the tightest gap are the same tier. $3–5 million is where the most buyers are shopping at once, which means a well-priced house in that range gets seen by the largest pool of people who can actually write the check — and bid accordingly.
The two ends behave differently. Under $2 million, financing and contingencies do more of the negotiating: a buyer stretching for an entry-level Nantucket house has less room to move on price, and more reason to ask for it. At $10 million and up, there often isn’t a tight cluster of comparable sales to price against — those houses are closer to one-of-a-kind, and a seller’s number is sometimes more aspiration than analysis. Twelve sales a year doesn’t give you much of a market to read.
What September added to the picture
September itself was the year’s biggest month by dollar volume — $240.6 million across 51 sales of all types, up from August’s $151.0 million — and the median home sale that month, $3,999,000, was up 4.5% from a year earlier. But only 2 of September’s 47 home sales closed above $10 million. The month’s size came from volume moving through the middle of the market, not from a run of trophy closings. (Source: The Kalman Co.

Myths I keep hearing about the Nantucket market
Myth: Prices are up across the board, so everything is selling for more than it’s worth.
Fact: The 2026 YTD home median is $3,700,000, up 12.1% from $3,300,000, while the YTD average sits at $4,694,000, up 8.0% from $4,348,000 — both climbing, with the median actually outpacing the average. (Source: The Kalman Co. Market Report, September 2026 edition, LINK data through Sept. 30, 2026.) What this means: this isn’t a few giant sales skewing an average while the typical house sits still — the gains are broad, which is a healthier kind of “up” than the headline number alone tells you.
Myth: With prices this high, a lot of what’s selling is at the very top.
Fact: Only 12 of this year’s 184 home sales — 7% — closed above $10 million; the $3–5 million tier alone accounted for 55 sales, 30% of the year’s total. (Source: The Kalman Co. Market Report, September 2026 edition.) What this means: the island’s real volume is in the middle of the market, not the headline-grabbing closing you read about — plan your search, or your pricing, around where the buyers actually are.
Myth: Asking price is just an opening offer everywhere on this island.
Fact: Homes priced $3–5 million closed at 96.2% of their final ask this year — the tightest gap of any tier — while homes under $2 million captured 91.3% and homes over $10 million captured 90.5%. (Source: The Kalman Co. Market Report, September 2026 edition.) What this means: if you’re pricing a house in that middle band, there’s very little room to pad the number and still expect it to work — buyers there are paying close to what’s asked, and that cuts both ways at the negotiating table.
Myth: Inventory is loosening up as the year winds down.
Fact: Active listings fell from 180 in September 2025 to 154 this September — down 14.4% — while residential absorption actually tightened, from seven months of supply in August to five in September, as residential listings dropped from 157 in July to 135 in August to 123 in September. (Source: The Kalman Co. Market Report, September 2026 edition.) What this means: the shelf isn’t filling back up for fall — it’s draining faster than it was over the summer, and buyers waiting for more to choose from are watching the opposite happen.
What this means for you
If you’re selling in the $3–5 million range, price it where the comparables actually are — you’re in the tier with the most competition and the least room for a number that doesn’t match the house. If you’re at either end, entry-level or ultra-luxury, build in more room on both sides of the table: the data on those tiers says buyers and sellers are landing further apart before they land at all. And if you’re buying anywhere in the middle of this market, don’t go looking for negotiating room that isn’t there — the numbers say you’ll need to move at something close to the asking price, because everyone else shopping alongside you is prepared to.
