Active listings fell nearly a fifth this summer, price cuts all but disappeared, and the medians moved together for once. Here’s what August’s numbers actually say about where the market stands heading into fall.
The for-sale list got shorter all summer
As of August 31, 2026, Nantucket carried 171 active listings across every property type, down 19.0% from 211 a year earlier. Residential inventory alone fell from 157 homes to 135 between the end of July and the end of August. That’s not a seasonal blip; it’s the island’s supply tightening in real time, in the month sellers traditionally list the most.

Fewer sales, not softer prices
Year to date through August, total sales are down 22.7% (167 versus 216 over the same stretch in 2025), and home sales specifically are down 14.4% (137 versus 160). But the median home price, homes only, not blended with land or commercial, is up 10.6% to $3,650,000, and the average home price is up 11.7% to $4,679,000. When the median and the average move the same direction, that’s a real signal, not a mix-effect fluke: what’s closing this year is commanding a genuine premium, not just skewing toward one or two outlier trades.

Sellers stopped discounting to sell
In August, only 37 listings took a price change, down 38.3% from 60 a year ago, even as new listings rose 16.1% to 65. Fewer price cuts against more fresh inventory tells me sellers priced right the first time this year instead of testing the market and hoping. I’m advising clients to treat the first ask as close to the real number, because the room to negotiate down just got smaller. (Source: thekalmanco.com/market-report, LINK Market Snapshot.)
What a seven-month supply means for you
Residential absorption sat at 7 months as of August 31, land at 4 months, commercial at 16. A seven-month supply isn’t a crisis, but it’s not the loose, pick-your-house market some buyers remember from a few years back either. If you’re waiting for more inventory to show up before you commit, the data says you may be waiting past the window you actually wanted.
What I’m telling clients right now
None of these four numbers moves in isolation. Fewer listings, fewer price cuts, and a median and average that finally agree all point the same direction: the sellers who are transacting right now have the upper hand, and they know it. For a buyer, that means doing the homework (financing lined up, a clear sense of the neighborhoods that fit) before the right listing shows up, not after. For an owner thinking about selling, it means this fall is not the moment to underprice out of nerves about the sales-count headline. The count is down. The value underneath it is not.
Myths I keep hearing about the Nantucket market
Myth: Prices must be falling with sales down this much.
Fact: Sales are down 22.7% year to date, but the median home price is up 10.6% to $3,650,000 and the average is up 11.7% to $4,679,000 over the same period. (Source: thekalmanco.com/market-report, LINK YTD Sales Summary, through August 31, 2026.) What this means: fewer transactions doesn’t mean cheaper houses. Right now it means the ones that do sell are higher-value, and I tell buyers not to wait on a discount the numbers don’t support.
Myth: There’s more to choose from than last year.
Fact: Active listings fell from 211 to 171 year over year, a 19.0% drop, and residential inventory alone fell from 157 to 135 homes in a single month. (Source: thekalmanco.com/market-report, LINK Inventory Activity.) What this means: if you see something close to right, I’m not telling clients to wait for a better option. There may not be one on the horizon.
Myth: Sellers are cutting prices to get deals done.
Fact: Price changes in August fell 38.3% year over year, from 60 to 37, even with 16.1% more new listings hitting the market. (Source: thekalmanco.com/market-report, LINK Market Snapshot.) What this means: a lowball offer has less room to work with this year than it did last year. Sellers priced closer to right the first time.
Myth: August was a quiet month for sales.
Fact: August closed 31 sales both this year and last, for $151,026,700 in dollar volume this year versus $186,808,000 last year, the same number of deals, down 19.2% in dollar volume. (Source: thekalmanco.com/market-report, LINK Sales History.) What this means: the month wasn’t slow, it was lighter at the very top. Fewer eight-figure trophy sales, not fewer buyers closing.
