If you are thinking about buying or selling in Brentwood this season, here is where the market stands heading into the end of 2026, and what I think it means for you.
Brentwood home prices this fall
For the three months ending September 30, 2026, Brentwood's median sale price was about $1.35 million, down 3.6% from a year earlier, according to Redfin. Homes took a median of 61 days to sell and closed at about 97% of their list price.
Brentwood prices vary widely by neighborhood, lot size, and age of home, and different data sources report somewhat different medians. The overall picture is consistent, though: prices are holding near their highs, and buyers are taking more time and negotiating more than they did a year or two ago.
The Williamson County picture
Across Williamson County in September 2026, based on Realtracs MLS data reported by local brokerages:
The median sale price was about $950,000
About 404 homes closed, up roughly 7% from September 2025
Homes averaged about 41 days on the market
Active inventory was up about 15% from a year earlier
Supply reached about 5.2 months, up from roughly 4 months in June
More homes are for sale, and they are staying on the market a little longer. Sales are still steady, which tells me demand for Williamson County has not gone away.
Mortgage rates are the big factor
The 30-year fixed mortgage rate climbed through the fall, from 6.95% in mid-September to 7.40% in mid-October, before easing slightly to 7.32% the week of October 22, according to Freddie Mac. On a $1.35 million home, each half-point increase in rate adds hundreds of dollars to a monthly payment. Rate changes affect buyers at every price point, including those buying with significant equity.
What this means if you are buying
You have more choice and more time than in the last few years, especially on homes that have been listed for a while.
Negotiation is back. Seller credits toward a rate buydown or closing costs can be worth more than a lower price.
Well-priced, move-in-ready homes still sell quickly. Be prepared with a pre-approval so you can act when the right home comes up.
New construction is worth a look. Many builders are offering incentives right now. I cover what to know in New Construction in Williamson County: What Buyers Should Know.
What this means if you are selling
Pricing matters more than it has in years. Buyers compare carefully, and an overpriced home tends to sit and then sell for less.
Presentation counts. Small repairs, fresh paint, and good photography help your home stand out among more listings.
Be open to creative terms. Offering a credit toward the buyer's interest rate can bring in more buyers than a small price cut.
Want numbers for your street?
Market-wide medians are a starting point, but the value of a specific home depends on the neighborhood, the lot, and recent sales nearby.
