Ask a buyer what the “median” Nantucket home costs, and the honest answer depends on whether land sales are folded into that number. Nine months into 2026, the gap between those two medians is wide enough that it changes the story.
The number in the headline isn’t the number for your house
Every market report has a median, and most readers assume there’s only one. There isn’t. Across every closed sale on Nantucket this year — houses, land, and commercial together — the median sits at $3,095,000. Look only at homes, and the median is $3,650,000, up 10.6% year over year. That’s a $555,000 difference between “the Nantucket median” and “the median Nantucket home,” and it’s the single most common mix-up I hear from buyers who’ve been reading headlines instead of listings.
If you’re shopping for a house, the homes number is the one that describes your search. The all-types number is describing a market that includes things you’re not buying.
Where the gap comes from
Twenty-four land parcels have sold so far this year, at a median price of $1,491,000 — well below what a finished house commands. Blend two dozen land sales into the same pool as 137 home sales and the composite median gets pulled down even while home prices themselves keep climbing. It’s not that Nantucket real estate is cooling; it’s that land and houses are two different markets wearing one number.
The average tells a related but distinct story. The average home sale price YTD is $4,679,000, nearly $1.03 million above the median. That gap is the fingerprint of a handful of very large waterfront trades pulling the mean upward while the typical sale — the one most buyers will actually experience — sits at the more modest $3.65 million. When average and median disagree by that much, both numbers deserve to be in the sentence, not just whichever one makes a better headline.
Where the pace is actually tightening
“Everything sells fast here” isn’t quite right either — it depends what you’re buying. Residential inventory stands at 135 active listings, which works out to roughly seven months of supply at the current sales pace. Land, with only 14 listings on the market, is tighter: about four months of supply. Commercial space is the outlier, sitting at a 16-month absorption rate — plenty of room to negotiate if that’s your search.
So if you’ve heard that Nantucket land is “impossible to find,” that’s closer to true than the same claim about houses. Buyable land is scarcer, relative to demand, than a finished home is right now.
What sellers are actually getting
August closed 27 home sales at 97.5% of asking price, with 14 of those 27 — over half — going at or above full ask. Year to date, homes are averaging 95.62% of ask. That’s not a market where sellers are getting picked apart; it’s one where a well-priced house is still commanding close to what it’s asking.
Myths I keep hearing about the Nantucket market
Myth: Nantucket prices are flat this year. Fact: The homes median is $3,650,000 through August, up 10.6% year over year. (Source: thekalmanco.com/market-report, LINK-sourced, YTD Jan 1–Aug 31 2026.) What this means: if you’ve been waiting for prices to come back to where they were last year, that wait has already cost you 10.6%.
Myth: The “median Nantucket home price” you read online is the price of a Nantucket home. Fact: The all-property-types median is $3,095,000 YTD — $555,000 below the $3,650,000 homes-only median, because it folds in 24 land sales with a $1,491,000 median. (Source: thekalmanco.com/market-report.) What this means: any number that doesn’t say “homes” or “all property types” out loud isn’t answering the question you’re actually asking.
Myth: There’s so much inventory right now that buyers have all the leverage. Fact: Residential absorption sits at seven months, but land is tighter at four months and commercial is loose at sixteen. (Source: thekalmanco.com/market-report.) What this means: leverage on Nantucket is never one thing — it depends entirely on which shelf you’re shopping.
Myth: Sellers are taking lowball offers to get deals done. Fact: Homes sold in August at 97.5% of asking price, with more than half closing at or above full ask. (Source: thekalmanco.com/market-report.) What this means: come in with a real number. A speculative lowball isn’t reading the room this year.
