The September 2026 market report for the Kennett Consolidated School District area has two numbers near the top of the first page. One is September's median sold price, $742,000, up 29% from September 2025. The other is the year-to-date median through September, $559,500, down 5.5% from $592,000 a year earlier.
One number says prices jumped and the other says they slipped. Both come from the same Tri-County Suburban REALTORS report built on Bright MLS data, calculated October 8, 2026. Neither one describes the price of the kind of home you're probably shopping for. Kennett Square isn't getting cheaper. The mix of homes changing hands has shifted, and that shift pulls the blended median down even as each type of home costs more.
Two Home Types, Both Up, One Median Down
Split the year-to-date figures into detached homes and attached homes, and the decline disappears.
| January–September | 2025 | 2026 | Change |
|---|---|---|---|
| Detached median sold price | $660,500 | $700,000 | +6.0% |
| Attached median sold price | $485,500 | $508,250 | +4.7% |
| Detached closed sales | 136 | 132 | -2.9% |
| Attached closed sales | 60 | 92 | +53.3% |
| All homes, median sold price | $592,000 | $559,500 | -5.5% |
Detached homes sold for more in 2026 than in 2025, and so did attached homes. The overall median still fell because attached homes went from about 31% of closed sales through September 2025 to about 41% through September 2026. A median is the middle sale in the line. When a large batch of lower-priced townhomes joins the line, the middle moves down, even though every part of the line moved up.
Statisticians call this a composition effect. For a buyer, the practical point is simple. If you're shopping for a detached home in the Kennett area, the market you face is about 6% more expensive through September than last year. The blended number suggests it softened, and it didn't.
Why The September Headline Overshoots The Other Way
The $742,000 September median makes the same mistake in the other direction. It rests on 29 closed sales. Nineteen of those were detached homes, with a September median of $828,722, and 10 were attached, with a median of $506,030. With that few sales, a handful of large detached closings can push a monthly median up by six figures. The August 2026 median was $592,046, one month earlier.
For a sense of scale, Bright MLS's September 2026 report for all of Chester County counted 529 closed sales and a $554,900 median. A county number can absorb a few unusual sales. A school-district number with fewer than 30 closings can't. In the Kennett area, the year-to-date figures for each home type tell you more than any single month does.
Where The Extra Townhomes Are Coming From
The Bright MLS report doesn't say which of those 92 attached sales were new construction, so the townhome surge can't be pinned on any single community. What is on the public record is that new attached homes have been reaching the market in Kennett Township during this stretch.
The clearest example is Kennett Pointe, Montchanin Builders' 53-townhome community at East Cypress Street and Ways Lane. As of mid-October 2026, the builder's page lists one final home at about $575,000. A community that started at 53 homes and is now on its last one has been closing sales right through the period covered by the table above.
The second is The Parks at North Walnut, which began as Parkside. The plan covers 16 acres on the east side of Walnut Road, just south of U.S. Route 1, with a crosswalk planned to Anson B. Nixon Park. It calls for 72 attached homes, 7 single-family homes, 104 apartments and two commercial or retail uses. Kennett Township's supervisors approved it with conditions on March 20, 2024. Township staff reported initial site work underway in September 2025. The township's February 2026 permit register shows townhouse permits on Louie Lane. With 72 attached homes planned, the pipeline there has a long way to run.
Townhomes aren't getting the new supply by chance. Kennett Township has kept most of its residential growth close to the borough, where water and sewer already exist, while pursuing the county's goal of 30% open space, according to the Inquirer's May 2026 reporting. Building densely on a limited footprint near existing infrastructure means attached homes. Detached sales have stayed about flat because the land model favors townhomes.
The Borough's Last Big Parcel Won't Change This Soon
The other piece of the supply story sits inside Kennett Square Borough. The borough covers about one square mile, and the Inquirer reported in May that it has one undeveloped parcel left, the former National Vulcanized Fiber site.
The Inquirer reported in August 2026 that borough council voted 5-2 to advertise a zoning change. The change would allow townhomes, apartments and single-family attached homes on the roughly 22-acre site, with 15% of units required to be affordable. In September, the Daily Local News reported a 4-2 council vote against continuing to table the rezoning, which it described as covering 24 acres and 300 housing units.
The timeline is the part that matters for a buyer this year or next. The ordinance still had to go through county review and a public hearing. If it passes, the developer can then submit a land development application. Officials told the Inquirer the process could take 18 to 36 months. The U.S. Environmental Protection Agency and the Pennsylvania Department of Environmental Protection must also sign off on site cleanup before construction can start. None of that adds a home to the market a buyer can tour in 2027.
Meanwhile, demand hasn't eased. Kennett Square Borough's population grew 16% from 2020 to 2025, the largest percentage gain in Chester County, and Kennett Township grew nearly 12%, per the Inquirer's analysis of Census estimates. "We're bursting at the seams," Kennett Township supervisors chair Pat Muller told the paper.
The Two Segments Are Moving At Different Speeds
Splitting the data by home type also shows the two segments at different temperatures heading into fall. The report measures balance with a contract ratio, which is pending sales divided by active listings.
- Detached homes, September 2026: 43 active listings, an average of 19 days on market, 100.0% of original list price, and a contract ratio of 0.86. That's up from 0.62 in September 2025 and slightly above the five-year September average of 0.83.
- Attached homes, September 2026: 40 active listings, an average of 10 days on market, 100.6% of original list price, and a contract ratio of 0.53. The five-year September average is 1.54.
The attached numbers seem to pull in two directions, and they explain each other. Townhomes that sold in September went fast and at full price. At the same time, 40 attached listings were active against 21 pending deals, and attached supply was 21.2% higher than in August. Well-priced townhomes still sell quickly. More townhomes are also sitting on the market than at any September in the past five years, which gives a townhome buyer more choice than the 10-day figure suggests. On the detached side, demand is running ahead of its usual pace for this time of year.
What To Bring To A Kennett-Area Search
- Compare by home type. Weigh a detached listing against the $700,000 detached median through September 2026 and a townhome against the $508,250 attached median. The blended $559,500 mixes two different markets.
- Expect townhome sellers to be checking the same new-construction prices you are. A resale townhome nearby competes with a new one at about $575,000 at Kennett Pointe and with homes still to come at The Parks at North Walnut.
- Count the school tax in your monthly budget. The Kennett Consolidated School District set its 2026–27 millage at 36.2036, a 3.46% increase. The district estimated that works out to about $218 more per year for the average residential property owner, according to its June 2026 budget letter. The district's tax page lists the current rates, including the 0.5% school district share of the real estate transfer tax.
- Watch the October report before you set an offer strategy. Tri-County Suburban REALTORS updates its monthly reports around the 12th of the following month, so October figures should be out in mid-November. The association notes that its statistics are preliminary and subject to minor revision.
The tax figures above are general information, not tax or financial advice. Confirm the numbers for a specific property with the district or a qualified professional before you rely on them.
If the blended median has been shaping your Kennett Square price range, it's worth running the numbers again by home type.
