Nantucket's August: the year's biggest month, and the shelf finally turned

LINK's August numbers are in, and they rewrite the summer's headline. August — not July — was the year's biggest month, by count and by dollars. And for the first time since February, the island's inventory fell.

The biggest month of 2026, on every measure

August closed 31 sales for $151,026,700 — the largest monthly total of the year by count and by dollar volume, ahead of July's 25 sales and $117.1 million. It got there on 27 home sales, three lots and one commercial property. (Source: LINK Nantucket, Year-to-Date Sales Summary and Sales History, August 2026.)

A year ago, August 2025 also closed exactly 31 sales, for $186.8 million. The count held; the money came in 19% lighter. The reason is in the mix: the homes that traded last August carried a $4,925,000 median and a $6,473,000 average, against $4,200,000 and $5,330,619 this year. Across all property types, August's median sale was $3,900,000.

Fewer trades than the year before has been 2026's shape all along. August is the first month that matched last year's count outright.

What actually sold

The top of the market showed up. The month's headline trade was 6 Berkeley Avenue on Monomoy — $15,000,000, at full asking price, the third-largest home sale of 2026. 174 Cliff Road followed at $13,500,000 against a $14,995,000 ask, and 14 Correia Lane in Surfside closed at $10,350,000. Three trades above $10 million in one month, against one in July; eleven homes at $5 million and above, against five. (Source: LINK Nantucket, Sales History, August 2026.)

The depth was in Town again. Seven of the 27 home sales closed in and around downtown, from a $1,600,000 unit on Center Street to $9,950,000 on North Water Street, with 8 & 10 Sea Street and 10 Still Dock both closing at exactly full ask. The Cliff had four sales of its own — 174 Cliff Road, 7 Pilgrim Court at a full-ask $7,195,000, 86 Cliff Road and 10 Pilgrim Road — and Tom Nevers three, led by 34 Bosworth Road at $7,750,000. The entry point of the month sat in Mid Island: 22 Green Meadows at $1,549,000 and 16 Allens Lane at $1,550,000, both at full ask.

Land was quiet. Three lots traded for a combined $5.1 million: 2 Wamasquid Place in West of Town at $2,900,000, full ask, and the paired 7 and 9 Fawn Lane parcels in Mid Island at $1,100,000 each. LINK puts land absorption at four months of inventory. One commercial property closed — the units at 26 Easy Street, at $2,000,000 — the first commercial sale on the island since June.

The full August table, address by address — all 31 closings, each with its last ask and sale-to-ask — is on the recent-sales page.

97.5% of ask — and half the homes at full price

Here is the number I'd frame from this report: 14 of the 27 homes that closed in August sold at or above full asking price. As a group, homes captured 97.5% of their last ask; two ran past it — 9 Carew Lane in Sconset at 101.2% and 2 Paupamo Way in Nashaquisset at 100.2%. The widest misses were 174 Cliff Road at 90.0%, 247 Polpis Road at 90.3% and 21 Exeter Street at 90.8%. (Source: LINK Nantucket, Sales History, August 2026.)

In the same 31 days, 37 listings changed price — the same count as July, and 38% fewer than last August — and 17 came off the market. Those facts are the same mechanism seen from both ends. This market pays promptly, and pays full price, for a house priced to what the island actually trades at; it sends everything else back for revision, or off the market entirely. The band-by-band version of that pattern is in the Q2 asking-versus-getting breakdown, and August sat right on it. (Source: LINK Nantucket, Inventory Activity, August 2026.)

Inventory turned

Inventory started August at 178 and ended it at 171. That is a small move on its face, but it is the first monthly decline since February — five straight months of growth, March through July, ended here. The residential shelf moved much harder than the total: 157 homes for sale at the end of July became 135 at the end of August. At August's sales pace, LINK puts residential absorption at seven months of inventory, down from eleven. (Source: LINK Nantucket, Inventory Activity and Market Snapshot, August 2026.)

Three details inside that number:

• New listings kept coming — and came on priced under the shelf. Sixty-five new listings arrived in August, 16% more than a year ago. The thirty residential ones came on at a median ask of $5,235,000, below the $5,995,000 median of what was already for sale. That is the first month since May that new sellers priced under the standing inventory rather than over it.
• The pipeline into fall got fuller. Thirty-six purchase-and-sale agreements were signed in August, up 44% from July's 25. Accepted offers to purchase slipped to eight from twelve — the deals were converting, not stacking up.
• Some sellers chose the exit over the cut. Seventeen listings came off the market in August, up from eleven in July, while price changes held at 37. Not every seller who missed the summer cut the price; some stepped back instead.

Seven months is a real number and worth knowing — with the standing caveat that it's computed from a single month's pace, in a market where one month can double the next.

Where August's home sales landed

The island-wide median tells you less than where the individual sales actually fell. Ten of the 27 homes closed under $3 million; three cleared $10 million.

The year to date

Through August, Nantucket has recorded 167 sales for $710.4 million, against 216 sales for $834.4 million in the same stretch of 2025 — count down 23%, dollars down 15%. Homes are 137 of those sales, at a year-to-date median of $3,650,000, up 10.6% from $3,300,000 a year ago; a month ago that figure stood at $3,478,000, and 27 August closings at a $4.2 million median moved it. (Source: LINK Nantucket, Year-to-Date Sales Summary by Month, run September 2, 2026.)

The year-to-date average home sale is $4,679,000, up 11.7%, and homes have captured 95.62% of asking across the year. Across all property types — land and commercial included — the year-to-date median is $3,095,000, down 1.7%, because land has traded at a $1,491,000 median on 24 sales against 38 a year ago. Fewer trades, higher home prices, a thinner shelf: the second-quarter report called this a thin market rather than a falling one, and August is the strongest evidence for that reading so far.

Myths I keep hearing about the Nantucket market

Myth: Nothing closes in August — everyone's at the beach.

Fact: August 2026 closed 31 sales for $151,026,700, the most of any month this year by count and by dollars, and 36 purchase-and-sale agreements were signed during the month, up 44% from July. (Source: LINK Nantucket, Year-to-Date Sales Summary and Inventory Activity, August 2026.) What this means: the deals that close in October are being written right now. If you are waiting for the island to empty before you engage, the house you wanted may already be under agreement.

Myth: Nantucket prices fell this summer.

Fact: August's median home sale was $4,200,000 against $4,925,000 in August 2025 — but the year-to-date median home price is $3,650,000, up 10.6% from $3,300,000, and the year-to-date average home sale is $4,679,000, up 11.7%. (Source: LINK Nantucket, Year-to-Date Sales Summary by Month, run September 2, 2026.) What this means: one month's median is the mix of what happened to close; last August had a heavier top end. The year is up on fewer sales, and I price to the year, not to a month.

Myth: There's more to choose from every month.

Fact: Active listings fell from 178 to 171 in August, the first monthly decline since February, and the residential shelf fell from 157 homes to 135; residential absorption dropped from eleven months to seven. (Source: LINK Nantucket, Inventory Activity and Market Snapshot, August 2026.) What this means: the widest selection of the year was July. If you were waiting for more, you are now choosing from less — and what is left is asking more, with a $5,995,000 median.

Myth: Sellers here don't negotiate.

Fact: Fourteen of August's 27 home sales closed at or above full asking price and homes captured 97.5% of ask on average — but 37 listings cut their price during the month and 17 came off the market. (Source: LINK Nantucket, Sales History and Inventory Activity, August 2026.) What this means: the house priced to the evidence doesn't negotiate because it doesn't have to. The house priced to hope negotiates in public, one cut at a time. Decide which one you are going to be before you list.

What I do with this

With sellers, the August report is the pricing conversation in one page. Fourteen of 27 at full ask belongs only to houses priced to this month's market; the 37 price changes and the 17 withdrawals are what the alternative costs. If you're thinking about listing this fall, we price to the buyers who signed 36 agreements in August, not to the inventory asking $6 million, and the valuation is where that starts.

With buyers, the leverage shifted in August for the first time since spring: fewer homes on the shelf, seven months of supply instead of eleven, and the new arrivals priced under the standing inventory. The accurately priced house still commands full ask — half of them got it — so the opportunity isn't lowballing the fresh listing. It's the house that has been sitting since June and is now repricing toward the number the market already named. I keep a running list of those, and it's the first thing we'd walk through together.

Questions I'm hearing about the August numbers

How many properties sold on Nantucket in August 2026?
Thirty-one — 27 homes, three lots and one commercial property — for $151,026,700, the biggest month of 2026 by count and by dollar volume. The median home sale was $4,200,000, and homes closed at 97.5% of their last asking price. (Source: LINK Nantucket, Sales History and Year-to-Date Sales Summary, August 2026.)

What was the biggest sale of the month?
6 Berkeley Avenue on Monomoy at $15,000,000 — full asking price, and the third-largest home sale of 2026. 174 Cliff Road followed at $13,500,000 against a $14,995,000 ask. On the land side, 2 Wamasquid Place in West of Town closed at $2,900,000, also at full ask. (Source: LINK Nantucket, Sales History, August 2026.)

Is Nantucket inventory still growing?
Not as of August. Active listings fell from 178 to 171 during the month — the first monthly decline since February — and the residential shelf dropped from 157 homes to 135, taking residential absorption from eleven months to seven. New listings kept arriving, 65 in the month, but the 30 residential ones came on at a $5,235,000 median ask, below the $5,995,000 median of the standing inventory. (Source: LINK Nantucket, Inventory Activity and Market Snapshot, August 2026.)

Are Nantucket home prices up in 2026?
For the year, yes. The year-to-date median home sale is $3,650,000 through August, up 10.6% from $3,300,000 a year ago, and the average home sale is $4,679,000, up 11.7%. August's own median home, $4,200,000, was below August 2025's $4,925,000 — a single month's median moves with the mix of what closes, so read the year as the trend and the month as the texture. Across all property types the year-to-date median is $3,095,000, down 1.7%. (Source: LINK Nantucket, Year-to-Date Sales Summary by Month, run September 2, 2026.)

The one-line version

August was 2026's biggest month by count and by dollars, half its home sales closed at full ask or better, and the island's inventory fell for the first time since February — with the new listings priced under the shelf for the first time since May.

If you want to know where your house — or the one you've been watching — sits in that picture, I'm glad to run the numbers and walk you through it. No pressure, no obligation.
