If you only check one thing before you price a Spring Hill house or write an offer on one, check which county it sits in.
In September 2026, the median single-family home on the Williamson side of Spring Hill sold for $662,500. On the Maury side it was $502,000. Same city. Often the same 37174 ZIP. $160,500 apart.
And here's the part most people miss. Over the last year, the two sides went in opposite directions.
I pulled these numbers from RealTracs, our local MLS, on October 13, 2026, and split them at the county line, September 2026 against September 2025. Here's what they say, and what I'd do with them if you're selling or buying here right now.
The county line is a price line
Start with every residential sale, single-family homes plus condos and townhomes, on each side of the line.
| September 2026, all residential | Williamson side | Maury side |
|---|---|---|
| Median sale price | $563,950, down 19% from $699,730 | $500,000, up 16% from $430,547 |
| Closings | 36, down from 60 | 52, down from 55 |
| New listings | 63, down from 85 | 123, up from 105 |
| Active inventory (average) | 137, down from 151 | 228, up from 215 |
| Average days on market (closed) | 59, up from 24 | 42, down from 51 |
| Months of supply | 4.54, up from 3.08 | 5.05, up from 4.66 |
Based on information from Realtracs® for the period September 1, 2025 through September 30, 2026.
Look at that Williamson-side median, down 19%. Part of that is what sold, not only what homes are worth. A year ago, 3 of the 60 Williamson-side closings were condos or townhomes. This September it was 11 of 36, at a median of $239,372. More lower-priced sales in the mix pulls the median down.
That's why, for the real story, I look at single-family homes on their own.
One honest warning about a single month
This is a small month. On the Williamson side, 25 single-family homes closed in September 2026. Condos and townhomes were 11 closings on the Williamson side and 8 on the Maury side.
With that few sales, one or two unusual closings can move a median a long way. So read these as a snapshot of September 2026, not a verdict on Spring Hill. Before you put a price on a house or an offer, you want the closed sales in that subdivision, on that side of the line, not a citywide median.
The two sides moved in opposite directions
Here's single-family only, September 2026 against September 2025.
| Single family, September 2026 | Williamson side | Maury side |
|---|---|---|
| Median sale price | $662,500, down 7% from $710,000 | $502,000, up 14% from $441,340 |
| Average sale price | $674,208, down 9% from $740,570 | $581,634, up 10% from $527,258 |
| Closings | 25, down 56% from 57 | 44, down 6% from 47 |
| New listings | 60, down 14% from 70 | 109, up 47% from 74 |
| New under contract | 34, down 11% from 38 | 38, flat from 38 |
| Active inventory (average) | 109, down 14% from 127 | 187, up 20% from 156 |
| Average days on market (closed) | 46, up 96% from 24 | 44, flat from 44 |
| List to contract (average days) | 64, up 23% from 52 | 50, down 40% from 84 |
| Months of supply | 5.36, up 94% from 2.76 | 4.92, up 23% from 4.0 |
On the Williamson side, prices came down and sales slowed. The median dropped from $710,000 to $662,500. Closings fell from 57 to 25. And the homes still for sale are priced lower too: the average list price of active Williamson-side single-family homes went from $945,486 to $745,327, down 21%.
On the Maury side, prices went up. The median rose from $441,340 to $502,000, and the average from $527,258 to $581,634. Closings held close to last year, 44 against 47. What changed is how many homes came on the market: 109 new single-family listings in September 2026, up from 74.
So the gap between the two sides is narrower than it was a year ago. In September 2025 the single-family medians were $710,000 and $441,340. In September 2026, $662,500 and $502,000.
Supply is loosening on both sides
Months of supply is a simple idea. If no new homes came on the market, it's how many months it would take to sell everything that's for sale at the current pace. Higher means buyers have more to choose from.
Williamson side: from 2.76 months to 5.36. That nearly doubled. Fewer homes were listed than a year ago, 60 new single-family listings against 70, but sales slowed even more, so what's on the market is taking longer to clear. You can see it in the days. The average closed single-family home took 46 days on market, up from 24. The average time from listing to contract went from 52 days to 64.
Maury side: from 4.0 months to 4.92. More supply here comes from more listings, not slower sales. Active single-family inventory averaged 187 homes, up from 156. Days on market held at 44, the same as a year ago. And the homes that went under contract got there faster: 50 days on average from listing to contract, down from 84.
So "is the Spring Hill market slowing down?" depends on which side of the line you mean. On the Williamson side, the September 2026 numbers say yes by every measure of pace. On the Maury side, the pace held and prices rose, but there's a lot more for buyers to look at.
If you're selling in Spring Hill right now
On the Williamson side, last year's sale next door is not your price. A year ago the median was $710,000 and homes sold in 24 days. In September 2026 it was $662,500 and 46 days, with buyers looking at 5.36 months of supply. A buyer who has that many choices compares your house to all of them. I'd price it from this fall's closed sales in your own subdivision and what's under contract right now, and I'd get the house fully ready before the first showing instead of fixing things after the first price cut.
On the Maury side, rising prices come with more competition. The median went up 14%. But 109 new single-family listings hit the market in September 2026, against 74 a year earlier. Your house isn't only being compared to last year's sales. It's being compared to everything that just listed. The homes that sold went under contract in 50 days on average, so a well-priced house is moving. Pricing it as if the 14% applies to every house is how a listing sits.
On either side, the first thing I check is which county the house is in, because the comps have to come from the same side of the line. My Spring Hill seller's guide walks through pricing, costs and the timeline. If you want a number on your own house, start with a home evaluation.
If you're buying and deciding which side of the line to shop
I don't tell anyone which side to live on. What I do is show you what the same money buys on each side and let you decide.
Here's what September 2026 says:
- The price gap is real. $662,500 against $502,000 for the median single-family home. That's $160,500.
- On the Williamson side, you have more choice and more time than a year ago. 5.36 months of supply against 2.76, and homes averaging 46 days on market against 24. When a house has been sitting, asking the seller for something is a normal conversation.
- On the Maury side, prices are up but so are listings. The median rose 14%, and new listings rose 47%. Homes that went under contract got there in 50 days on average.
Price isn't the only thing that changes at the county line. The county property tax rate is different too. I broke that down, with the published rates, in Williamson County vs Maury County Spring Hill. For the neighborhoods themselves, here are the best neighborhoods in Spring Hill on both sides of the line, and my Spring Hill area guide covers the city as a whole.
What I'd do next
A citywide median can't price your house or your offer. The closed sales in one subdivision, on one side of the county line, can.
Text me your address, or the neighborhood you're watching, and I'll pull the closed sales on that side of the line and walk you through what they mean for you.
