Fairfield County Market Report: September 2026

The median sale price usually takes the headline when market reports are released, and in September it barely moved. Across the nine towns I cover, Greenwich, Stamford, Darien, New Canaan, Westport, Fairfield, Norwalk, Wilton and Ridgefield, a total of 228 single-family homes closed last month at a median of $1,225,000, compared to $1,250,000 in September of last year. Another 90 condos and 7 co-ops closed as well.

That small dip does not necessarily mean that your home would sell for less today than it did a year ago. The typical home that sold in September was smaller than a year ago, with a median of 2,603 square feet compared to 3,000 last year, while buyers paid more for each square foot of home. Homes also took longer to get under contract, though most of them still sold above their asking price.

September 2026 by the Numbers

Single-family sales, September 1 through 30, compared to the same month last year.

Closed sales: 228, down from 250 in September 2025, a decrease of 8.8%.

Median sale price: $1,225,000, down 2.0% from $1,250,000 a year earlier.

Median house size: 2,603 square feet, compared to 3,000 square feet last September.

Price per square foot: $498 at the median, up 14.0% from $436 last September.

Days on market: a median of 28 days, compared to 19 days a year ago.

Over asking: 60% of September's sales closed above their list price, up from 56% a year ago.

Supply: 569 single-family homes on the market as of October 5, about 2.5 months of inventory at September's pace, with another 348 under contract.

Condominiums and co-ops: 97 closed at a median of $535,000, compared to 131 at $510,000 a year ago. Fewer sales, at a slightly higher price.

Less House for Your Money

Price per square foot is the closing price divided by the home's square footage. If it climbs while the median sale price holds about steady, it means the same budget is buying a smaller home, and that is what happened in September.

The clearest example is the $1,000,000 to $2,000,000 price range, where a total of 83 homes sold. The median home in that range had 2,773 square feet, compared to 3,326 square feet last September, about 550 fewer square feet for this price range. Buyers in this range also paid more compared to the asking price: the median sale closed at 104.1% of its list price, or $104.10 in closed sales for every $100 in asking price, compared to 101.0% a year ago.

Part of this is the mix of homes that happened to sell, and one month of sales is a small sample. Still, every price range above $1,000,000 sold for more per square foot than it did last September.

Homes Took Longer to Get Under Contract

The other change was speed. Last September, 33% of single-family homes went under contract within 10 days on market. This September, only 12% did, and the median went from 19 days on market to 28.

A slower pace did not stop buyers from competing for the right homes. Of September's 228 sales, 137 closed above their asking price, at a median of 19 days on market. The other 91 sold at or below asking and took a median of 46 days on market. As in last month's report, a home that draws a buyer early tends to go over asking, and a home that sits on the market tends to give some of that asking price back.

Where the Competition Was Tightest

The sub $1,000,000 market cooled the most where just 58% of sales in this range closed over asking, compared to 69% last September, and the median time on market went from 12 days to 34.

Between $1,000,000 and $2,000,000, competition picked up: 68% of sales went over asking, compared to 55% a year ago, at a median of 20 days on market. Between $2,000,000 and $3,000,000, 50% closed over asking compared to 44% last September, at 31 days on market.

Above $3,000,000, 57% of sales closed over asking, compared to just 38% a year ago, and the median time on market dropped from 44 days to 28. September's largest sale was a 9,564 square foot colonial on Shorehaven Road in Norwalk, which closed at $10,000,000 after 91 days on market. The largest amount over asking came in Darien, where a colonial on Three Wells Lane listed at $5,195,000 sold for $6,100,000 after just 2 days on market. By percentage, the biggest jump came in Ridgefield, where a cape on Aspen Mill Road listed at $960,000 sold for $1,375,000, 143% of its list price, after 12 days on market.

Around the Nine Towns

September medians by town, with the number of sales for each. With as few as 11 sales in a town, one month is a small sample, so read these as a snapshot of September rather than a valuation of any one home.

Darien: $2,581,388 across 14 sales, 16 days on market, the fastest of the nine towns last month.

Greenwich: $2,525,000 across 15 sales, 31 days on market. Greenwich activity is likely understated, since Greenwich also runs its own MLS alongside SmartMLS.

New Canaan: $2,297,500 across 14 sales, 19 days on market.

Westport: $1,724,938 across 16 sales, 21 days on market.

Fairfield: $1,250,000 across 37 sales, 26 days on market.

Ridgefield: $1,197,000 across 20 sales, 31 days on market.

Wilton: $1,100,000 across 11 sales, 28 days on market.

Stamford: $1,057,500 across 46 sales, 35 days on market, the slowest of the nine.

Norwalk: $800,000 across 55 sales, 30 days on market, the busiest town of the month.

What This Means If You Are In The Market

If you are selling, the listing price you start with still decides how this goes. 60% of homes sold over asking in September, and those homes went under contract in a median of 19 days on market, while homes that sat on the market for more than a month were more likely to sell at or below their list price. With 569 single-family homes on the market as of this week, buyers have plenty to compare your home against, so pricing it right from the first weekend matters.

If you are buying, you most likely have more time than you did a year ago, especially under $1,000,000, where the median home took 34 days on market to sell compared to 12 last September. That said, the homes most buyers want are still drawing competing offers, and between $1,000,000 and $2,000,000 most of them closed above asking. Being ready to move when the right home comes up still makes a difference.

A note on methodology: closing figures above come from SmartMLS records for the nine towns named at the top, exported October 5, 2026, and cover single-family homes unless stated otherwise. Condominium figures combine condominiums and co-ops. Active and under contract counts are as of October 5, 2026, and under contract includes listings marked under contract, continue to show. Greenwich MLS listing activity is not included in these figures, which draw exclusively from SmartMLS, so Greenwich sales figures may be incomplete. These numbers describe the market as a whole and are not a valuation of any individual home.
