Wilson County Housing Market Holds Middle Tennessee's Tightest Supply as Sumner Follows and the Region Reaches 5.41 Months
The Wilson County housing market ended September with 4.22 months of supply, the region's tightest, with Sumner at 4.32 as Middle Tennessee reached 5.41.
Franklin, Tenn. — October 12, 2026
The Wilson County housing market finished September with the tightest supply in Middle Tennessee, with Sumner County close behind. The wider region continued to loosen in September, but the slowdown has not reached every county evenly, according to Realtracs MLS figures compiled in two local market reports published this month.
Middle Tennessee supply reaches 5.41 months
Across the ten-county region of Davidson, Williamson, Rutherford, Wilson, Sumner, Maury, Montgomery, Robertson, Dickson and Cheatham counties, closings totaled 3,073 in September, down 4% from a year earlier, according to an analysis of Realtracs data by agent Rochelle Romines. Active inventory averaged 14,249 homes, up 8% from September 2025, and months of supply rose to 5.41 from 4.87. The regional median sale price was $444,169, up 2%, while the average sale price rose 5% to $631,993.
Why the Wilson County housing market and Sumner County stay tight
Beneath those regional numbers, Wilson and Sumner counties stood apart. Wilson County recorded 307 closings at a median sale price of $499,900 and 4.22 months of supply, the lowest of the ten counties, according to a county-level table drawn from Realtracs data with an Oct. 4 report date. Homes there spent an average of 34 days on the market.
Sumner County was close behind, with 349 closings, a median sale price of $446,000, an average of 34 days on the market and 4.32 months of supply. Robertson County ranked third-tightest at 4.58 months, with 107 closings and a median of $375,000.
Wilson County's supply figure moved against the regional trend. The same reports show months of supply in Wilson at 4.41 in June, 4.51 in July and 4.70 in August before falling back to 4.22 in September. Williamson County, by contrast, climbed from 4.01 months in June to 5.33 in September, and Rutherford County rose from 3.96 to 4.91 over the same stretch.
Davidson and Williamson counties loosen
Davidson County, the region's largest market, posted 853 closings and the most supply at 6.46 months, with a median sale price of $450,000. Montgomery and Dickson counties followed at 5.83 and 5.81 months. Williamson County remained the price outlier, with 397 closings and a median of $950,000.
| County, September | Closings | Median sale price | Months of supply |
|---|---|---|---|
| Wilson | 307 | $499,900 | 4.22 |
| Sumner | 349 | $446,000 | 4.32 |
| Robertson | 107 | $375,000 | 4.58 |
| Davidson | 853 | $450,000 | 6.46 |

Housing economists commonly treat roughly five to six months of supply as the line between a seller's market and a balanced one. By that measure, most of the region has moved into balanced territory, while Wilson, Sumner and Robertson counties remain somewhat tighter.
The regional figures line up with the separate monthly report from Greater Nashville Realtors, which covers nine counties and does not include Montgomery County. That report showed 2,885 closings in September, 2,045 pending sales and inventory of 15,536 homes, with a single-family median price of $510,000, according to a summary published Oct. 7.
The broader backdrop remains higher borrowing costs. Freddie Mac's weekly survey put the average 30-year fixed rate at 7.40% for the week ending Oct. 8, the highest since November 2023.
What tighter supply means for buyers and sellers
For buyers looking in Wilson and Sumner counties, the tighter supply suggests less room to negotiate than in Davidson or Williamson, particularly on homes priced in line with recent sales. Buyers comparing counties may find that a short difference in commute translates into a meaningful difference in competition. For sellers in those counties, conditions remain comparatively favorable, though the region-wide rise in inventory means pricing still matters.
