Williamson County: Q2 2026 Market Report

People hear 'Williamson County' and picture one market. There isn't one. Brentwood, Franklin, Nolensville, Spring Hill, and College Grove all sit inside the same county lines and behave like five different planets. The county median is a useful number right up until you try to buy a house with it, at which point it tells you almost nothing. So here's the top-line read, and then we'll break it apart.

Submarket Variation

Brentwood (37027)

Median sale price about $1.18M. Well-priced homes under $1.5M still draw multiple offers; stretch-priced homes sit and collect days on market, which is the polite way of saying the house is telling you the number was wrong. The $2M+ luxury band has softened slightly from peak — well-presented homes still trade, but list-to-sale ratios have come back down to earth.

Franklin (37064, 37067, 37069)

Median around $880K. Westhaven and historic downtown Franklin command consistent premium. The under-$1.2M band sees multiple offers on well-priced homes. Westhaven stays consistently active.

Nolensville (37135)

Median around $760K. Steady activity across the buyer pool. Newer subdivisions move well; older inventory benefits from updates before listing.

Spring Hill (Williamson side, 37174)

Median around $580K. A very active first-time-move-up market in the county. Multiple-offer activity common at correct pricing.

College Grove (37046)

Lower volume, premium pricing for larger-lot and equestrian properties. The $1.5M+ band requires patient marketing.

Property-Specific Factors Driving Outcomes

• •Lot size — homes on 0.5+ acre lots command meaningful premiums.
• •Garage configuration — 3-car standard at $900K+; 4-car preferred at $1.5M+.
• •Recent renovation — fully updated outperforms partially updated.
• •Outdoor living — pools, outdoor kitchens, covered porches when well-designed.
• •Main-level primary suite — increasingly important for aging-in-place and downsize buyers.
• •School address verification — Williamson County zoning shifts periodically; verify each address.

What's Currently Driving Buyer Activity

• •Relocation from higher-tax states (California, Illinois, New York remain strongest source markets).
• •Out-of-state buyers who want to research school zoning on their own — when you share an address, our team pulls the assigned schools and the GreatSchools.org and TN DOE report cards so you decide.
• •Healthcare executives at Williamson Medical Center and broader medical corridor.
• •Established Nashville buyers trading up from Green Hills, West End, Belle Meade.
• •Music industry professionals seeking residential base outside downtown Nashville.

What We Tell Buyers

1. Pre-qualify before touring; multiple-offer activity continues in well-priced bands.
2. Williamson County-experienced inspectors matter — septic, well, and ridge-line drainage considerations.
3. Pull permit history on additions, pools, and outbuildings.
4. Verify school zoning specifically by address.
5. Drive the commute at peak times before committing — I-65 north out of Franklin and Cool Springs at 5pm is a different animal than the same road on a Sunday.
6. Set a walk-away number in writing before touring.

What We Tell Sellers

1. Price for current Q2 2026 reality — not 2022 peak. Pricing right at week one matters more than ever.
2. Pre-listing inspection earns multiples back at the contract stage.
3. Photography, drone, and staging are table stakes at this price band.
4. Off-market and pocket-listing strategies have a place in select premium segments.
5. Concessions are an expected part of the conversation again — plan accordingly.
