Brentwood's 37027 zip code closed homes across a nearly $4 million spread in the same six-month window this year. One end of that window was a $373,000 closing in an established 1980s subdivision. The other end was a new-construction enclave delivered in 2024 that posted a $4.32 million median for the same period. Same city. Same zip code. Same six months.
If you have been shopping the "Brentwood median" as your budget anchor, this is the moment to stop. That median, which sat around $1.32 million on trailing six-month closed sales through late June 2026, is not describing one market. It is averaging two of them together, and in a way that matters for how you set a budget, price a listing, or decide whether a house you love is even in the market you think it is.
The median is doing math on two different economies
Brentwood's zip code carries subdivisions built across five decades, and the closed-sale data breaks cleanly along build era rather than square footage or lot size. Brentwood Pointe, built in the 1980s, has closed homes in the $330,000 to $517,000 range. Mooreland Estates sits near $510,000. Courtside at Southern Woods, mid-2000s construction, lands around $920,000. All of these are real, recent closings inside the same zip code that produced that $1.32 million median.
On the other end, new-construction communities like Rosebrooke have closed 20 sales in a rolling 12-month period, and a newly built estate in the gated community of Anna, off Anna Drive and McCall Court, closed at $6.28 million, working out to $720 per square foot. Callie, a hamlet-style development drawing on a Florida 30A aesthetic, has priced homes from roughly $1.87 million to $3.3 million.
The sub-$1 million inventory in Brentwood is almost entirely established resale. New construction essentially does not exist below that line. So when you see a Brentwood median north of $1.3 million, you are not looking at what a typical Brentwood home costs. You are looking at an average that blends 1980s ranch-style resale with brand-new custom estates, and the number that comes out the other side describes neither one accurately.
Here is what that split looks like when you separate it by build era and price band:
| Subdivision | Build era | Recent closed range |
|---|---|---|
| Brentwood Pointe | 1980s | $330,000 to $517,000 |
| Mooreland Estates | 1980s to 1990s | Around $510,000 |
| Courtside at Southern Woods | Mid-2000s | Around $920,000 |
| Rosebrooke | New construction | Multiple closings, luxury tier |
| Callie | New construction | $1.87 million to $3.3 million |
| Anna | New construction | $6.28 million (one recorded closing) |
If your budget sits at $650,000, the Brentwood median is telling you almost nothing useful. Your actual competition is Brentwood Pointe and Mooreland Estates, not the new-construction enclaves pulling the citywide number upward.
The zip code has a second split most buyers never check
Here is the part that catches people off guard even after they understand the build-era gap. Brentwood's 37027 zip code does not sit entirely inside Williamson County. It spans the county line, with a portion of Brentwood addresses actually sitting in Davidson County. Two houses can share the same "Brentwood, TN 37027" mailing address and belong to different counties entirely, which means different school districts and different property tax jurisdictions.
The price data reflects that split just as sharply as the build-era split does. New construction on the Williamson County side of the zip code has closed at a median around $3.43 million. New construction on the Davidson County side has closed at a median closer to $1.88 million, and those homes are zoned for Metro Nashville Public Schools rather than Williamson County Schools. Roughly three out of every four new-construction sales in the zip code have happened on the Williamson County side, which is part of why the county line is easy to miss. Most of what gets built and marketed under the Brentwood name is on the Williamson side, but not all of it, and the addresses look identical on paper.
This is not a detail you can eyeball from a listing photo or a street name. It is a parcel-level question, and it is one worth resolving before you get attached to a specific house.
What this means when you are setting a number
The practical cost of anchoring to the wrong number shows up in weekly county-wide data on overpriced listings. As of the week ending April 25, 2026, Williamson County homes that had to take a price reduction were taking roughly 64 extra days to sell compared to correctly priced homes, and netting about 8.4 percent less than their original list price, which worked out to more than $100,000 on the average home in the county at that time. Sellers who priced correctly from the start were getting close to 99 percent of asking price and selling in around 39 days. That gap was not random. It showed up most often when a seller or a buyer started from the wrong comparison set, whether that was the citywide median instead of the subdivision, or the wrong side of a county line.
As of the week ending August 1, 2026, Williamson County's overall inventory stood at 1,706 active listings with 3.92 months of supply, a market sitting close to balanced but leaning slightly toward buyers compared to a year earlier. Brentwood's single-family segment specifically has carried noticeably more supply than that countywide figure, based on the six-month closed-sale dataset through late June 2026, which means buyers in the established resale tier have more room to negotiate than the headline luxury closings suggest, and sellers in that same tier are competing directly against builder incentives on the new-construction side, including rate buydowns and upgrade packages that established homes cannot offer without their own version of a first impression.
That is where presentation earns its keep. A well-maintained 1980s resale competing against a 2024 build with a builder-funded rate buydown does not need to match the new-construction price. It needs to close the gap in finish and feel, which is exactly the kind of pre-market work that pays off in a market where buyers are actively comparing both categories.
The diagnostic questions before you write an offer or set a list price
Before you anchor a budget, a listing price, or an offer to any number you have seen for Brentwood, run through these:
- What build era is the specific subdivision, not the zip code as a whole?
- What are recent closed prices in that subdivision specifically, not the city median?
- Which county does this exact parcel sit in, and which school district does it feed into?
- If you are a seller in an established subdivision, what is new construction currently offering in incentives, and does your home need a presentation update to compete on more than price alone?
None of these require guesswork. They require pulling the parcel record and the closed comps for that specific street, not the city.
A few common questions
Does every Brentwood address split between two counties? No. Most of the zip code sits in Williamson County, and the split shows up most clearly in new-construction inventory, where about three-quarters of recent closings have been on the Williamson County side. But the boundary runs through the zip code itself, not around it, so it is worth confirming for any specific address rather than assuming based on the subdivision name.
Is new construction always going to cost more than resale in the same subdivision footprint? In Brentwood's data, yes, consistently. The sub-$1 million closings are almost entirely established resale, and new construction has not closed below that threshold in the recent dataset. The gap is not marginal, it is the difference between a few hundred thousand dollars and several million.
How do I find out which side of the county line a specific house sits on? This is a parcel-level question, not a subdivision-level one. The county assessor's parcel record will show the county and the school zone tied to that specific address, and it is worth checking before you make an offer, not after.
If you are trying to figure out which Brentwood market your budget or your listing actually belongs in, that is exactly the kind of question we work through with clients every week.
