September held prices steady, with a $1.1M rolling 12-month median that matches August’s record high. The fall slowdown came a little early, though: buyers have more to choose from than they did a year ago, and they’re taking their time.
If August was “driving 45 in a 60,” September is that same car easing into the slow lane as the aspens turn. Here’s what the Summit County residential numbers show.
Prices: the middle keeps carrying the market
The rolling 12-month median sales price held at $1,100,000, the same as August and the highest in the dataset. That’s 7.8% above September 2025 ($1,020,000).
The rolling 12-month average dipped to $1.447M, down 1.0% from August ($1.461M) but still up 1.4% from last September ($1.427M). When the median holds and the average slips, fewer high-end sales are pulling the average up. Mid-priced homes are doing the work, just as they did this summer.
Inventory: buyers have more to choose from
Active listings fell to 948 in September, down from 994 in August and July’s peak of 1,020, which is normal for this time of year. It’s still 18.5% more than September 2025 (800) and the most for any September in the data, which goes back to 2018.
September 2025 was a standout month: its 181 closings were the most for any September since 2021. This year’s 127 is closer to the 2023 and 2024 pace (147 and 129). Year to date, the gap is small. Closings are off just 2.7% from 2025, so the year as a whole is still tracking close to last year.
These September counts are preliminary. Late-reported deals usually nudge them up a few in the weeks after month-end.
Days on market and months of supply
The rolling 12-month average days on market came in at 79 days. That’s up from 78 in August and 72 a year ago, and nearly four times the 21-day low of 2022.
By our math, 948 active listings against an average of about 118 closings a month (the last 12 months) works out to roughly 8 months of supply. A year ago it was about 6.8 months. That’s buyer-friendly territory, and it’s why pricing right on day one matters more than it has in years.
Hi Amy! I always enjoy your posts. One thing you may not know about: the lower end of the market has sunk substantially. A condo two doors down from us has been on the market for several months and is now listed for $374,500. We bought ours six years ago – a very similar condo – for $440,000. I imagine that now is a very good time for buyers looking at that end of the market.
