Williamson County Real Estate

Updated September 6, 2026 · 29 posts in this archive · 2008 to 2026 · Williamson County real estate coverage from Grant Hammond

Quick answer: Williamson County real estate coverage. Williamson sits immediately south of Nashville and contains Franklin and Brentwood. It trades as its own market with its own municipalities and school zoning, and Metro Nashville’s short-term rental permitting does not apply there.

Williamson County real estate coverage from Grant Hammond, in date order, from Realtracs MLS data for each period. Coverage is county-specific because a Nashville metro average describes Williamson badly. For the metro-wide series see the Nashville housing market archive.

What Williamson County Real Estate Coverage Includes

Median and Average sale price, closed volume, inventory and days on market for the county and for its individual cities. New construction activity by subdivision and by school-zone boundary, described as district geography rather than any judgment about it. Comparisons against adjacent Davidson County submarkets where a buyer is weighing the two. Current inventory sits at Franklin and Brentwood.

Which Cities Are in Williamson County, Tennessee?

Franklin is the county seat. Brentwood sits at the northern edge, directly against the Davidson County line. Nolensville, Thompson’s Station and Fairview make up the rest of the incorporated municipalities, Spring Hill straddles the boundary into Maury County, and areas such as Grassland and Leiper’s Fork are unincorporated county. The practical consequence for a buyer is that these are separate municipalities with separate zoning, separate permitting and separate school attendance boundaries, so two addresses fifteen minutes apart can sit under different rules and in different price bands. Metro Nashville’s short-term rental permitting stops at the Davidson County line and reaches none of them, which is the single most common assumption an out-of-market investor gets wrong.

Nashville and Middle Tennessee Coverage

Williamson County across price bands from under $500K through $2.5M and above, with Davidson County covered for contrast where the comparison is the actual question.
