September 2026 Nantucket Real Estate Market Report

September Sales Reach a New High

Nantucket's real estate market gained significant momentum in September, recording 51 property sales totaling approximately $240.6 million. This represented the strongest month of the year in both transactions and dollar volume, exceeding August's sales volume by nearly $90 million.

While the number of sales declined from September 2025, the market continued to demonstrate resilience, with well-positioned properties attracting serious buyers.

The median residential sale price reached approximately $4 million, reflecting continued strength in Nantucket's high-end market.

Luxury Properties Lead the Market

Luxury real estate played an important role in September's performance. The month's largest transaction was the sale of 69 Monomoy Road for $19.5 million, followed by 15 Deer Run Road at $12 million.

These transactions highlight the enduring appeal of Nantucket's premier locations and the continued willingness of buyers to invest in exceptional island properties.

Demand remained evident across several neighborhoods, including Town, Monomoy, Surfside, Sconset, and Tom Nevers.

Inventory Continues to Tighten

One of the most notable trends in September was the continued decline in available inventory.

The number of active listings fell from 171 at the end of August to 154 at the end of September. With fewer properties available, buyers faced a more limited selection heading into the fall market.

For sellers, this creates opportunities, particularly for properties that are well-maintained, appropriately priced, and effectively marketed.

For buyers, it reinforces the importance of understanding neighborhood values and being prepared to act when the right property becomes available.

A Look at the Year So Far

Through the end of September, Nantucket recorded approximately $951 million in total real estate sales across 218 transactions.

Although overall transaction volume remained below 2025 levels, the year-to-date median home sale price increased to approximately $3.7 million, up 12.1% from the previous year.

This suggests a market characterized by fewer sales but continued strength in residential pricing. The higher median also reflects a changing mix of properties sold, including fewer transactions at the lower end of the market.

Looking Ahead

As Nantucket moves into the final months of 2026, we expect limited inventory to remain an important factor in the market.

Historically, fall can be an active period for serious buyers and sellers. Those purchasing during this time often benefit from a less crowded market, while sellers have the opportunity to reach motivated buyers.

Although every property and neighborhood is different, Nantucket's long-term appeal, limited land supply, and distinctive lifestyle continue to make the island a desirable real estate market.
