Williamson County, Tennessee — Real Estate Market Report
Williamson County sits directly south of Davidson. Franklin is the county seat; Brentwood, Nolensville, Thompson's Station and part of Spring Hill are inside the line. This page reports housing figures for Williamson County city by city — Franklin, Brentwood, Nolensville, Spring Hill — because that is the level at which we can source and date every number. Each figure below states the period it covers and links where it came from.

Why there is no single Williamson County median on this page
We do not have a Williamson Countymedian from a primary source. Blending the city figures above into one county number would produce something that looks authoritative and can't be checked — and a county median hides the spread between these cities, which is usually the thing that actually matters to a decision. When we have a county-level closed-sales export we can attribute, it will appear here with its own date and methodology. Until then, the city rows are the honest answer.
Where each Williamson County figure comes from
Franklin
as of May 2026Median is a rolling 12-month figure through May 2026 (2,114 closed sales); a 3-month figure ending April 2026 was lower at about $850,000. Days on market is not published for Franklin: the figure previously carried here traced to a new-construction-only subset rather than the whole market.
Brentwood
as of May–June 2026Median sale price reported as a range for April–May 2026. New-construction listings early 2026 carried a much higher median list price (~$3.2M), reflecting the luxury custom segment.
Nolensville
as of May 2026Median sale price ~$924,318 (Redfin, May 2026).
Spring Hill
as of June 2026Spring Hill's city limits cross the Williamson–Maury line; it is listed under both counties.
We do not currently publish a median sale price or a days-on-market figure for Spring Hill. The figures we showed until September 2026 — about $539,000 and a days-on-market reading, both stamped June 2026 — trace to a city-wide median LIST price series and to the age of listings sitting on the market, not to closed sales, so they were withdrawn rather than relabelled inside a sale-price field. The months-of-inventory and new-construction figures below are single-family-only readings from February 2026, a different segment and window from the rest of this record.
