The Williamson County median sale price was $1,035,000 in July 2026, crossing the million-dollar threshold, with an average sale price of $1,354,577. That places Williamson well above the 10-county Middle Tennessee median of $457,500 and Davidson County’s $483,590. The gap between Williamson’s median and average indicates that upper-tier transactions are carrying a disproportionate share of the market, which is consistent with the regional pattern.

It is loosening rather than slowing sharply, and the mechanism matters. Regional active inventory is up 9 percent year over year while new listings are down 19 percent, which means homes are sitting longer rather than more homes arriving. Regional days on market rose 6 percent to 33 days and list-to-contract time rose 14 percent to 58 days. Williamson County itself still absorbs quickly at 28 days on market on 4.59 months of supply, so well-priced Franklin homes are not sitting.

It leans seller but has moved toward balance. Williamson County holds 4.59 months of supply with homes going to contract in 28 days, which favours sellers. What has changed is that regional inventory is up 9 percent, days on market are up 6 percent and list-to-contract times are up 14 percent year over year, giving buyers more selection and more negotiating room than a year ago. Sellers retain the advantage on well-priced homes; the penalty for overpricing has grown.

Williamson County homes averaged 28 days on market in July 2026, with 51 days from list to contract. Across the broader 10-county Middle Tennessee region the figures were 33 days on market and 58 days list to contract, both up year over year, by 6 percent and 14 percent respectively. Williamson remains one of the faster-absorbing markets in the region, second only to Wilson County at 27 days among the major counties.

The regional average-to-median spread widened to $189,375 in July 2026, with the average at $646,875 against a median of $457,500. That spread reflects upper-tier transactions pulling the average upward. The year-over-year pattern confirms it: the regional average rose 6 percent while the median rose only 2 percent, meaning the top of the market is appreciating while the middle is close to flat. Williamson County, at a $1,035,000 median and $1,354,577 average, is where much of that upper-tier activity sits.

Davidson County, home to Nashville, carries the loosest supply among the region’s largest counties at 5.97 months, the closest thing in Middle Tennessee to a balanced market, with 31 days on market. Rutherford County is the tightest at 4.02 months of supply. Williamson County sits at 4.59 months and Wilson County at 4.51. Regionally, months of supply reached 4.92 in July 2026, up 17 percent from 4.2 a year earlier.

Spring Hill, with a 2026 median around $550,000 and one of the region’s most active new-construction markets, is the most common alternative, though buyers must confirm whether an address falls on the Williamson or Maury county side because that determines the school district. Thompsons Station, at a 2026 median around $890,000, sits entirely within Williamson County and offers more land at a lower price than Franklin’s core. Countywide, Maury’s median was $422,100 and Rutherford’s $430,500 in July 2026.

Yes, but modestly and unevenly. The regional median rose 2 percent year over year to $457,500 in July 2026 while the regional average rose 6 percent to $646,875. That divergence indicates growth concentrated in the upper tier rather than across the market, with middle segments showing gains in the 1 to 3 percent range. Williamson County crossed the $1,035,000 median mark, continuing to lead the region on price.

Conditions for buyers have improved from a year ago: regional active inventory is up 9 percent, days on market are up 6 percent, and list-to-contract time is up 14 percent, all of which mean more selection and more negotiating room. At the same time new listings are down 19 percent, so the improvement comes from slower absorption rather than fresh supply, and well-priced Williamson County homes still go to contract in 28 days. Buyers who are ready should be pre-approved and prepared to act on the right property rather than waiting for a broad correction the data does not show.

County medians and regional statistics provide context but cannot value an individual property, since Franklin neighborhoods vary widely around the county figures and condition and product type drive much of the difference. The Hetherington Team prepares neighborhood-level and product-level valuations using current closed-sale data for the specific area, which is the only basis on which a listing price should be set in a market where list-to-contract times are lengthening and the penalty for overpricing has grown.
