Southlake Real Estate Market Update: September 2026
Two things happened to the Southlake market this month, and they pull in opposite directions.
Mortgage rates jumped. The 30-year fixed averaged 6.95% on September 17, its fourth straight weekly increase and the highest reading since January 2025, according to Freddie Mac. A year ago it sat at 6.26%. The Federal Reserve raised its benchmark rate on September 16, its first hike since 2023, after the 10-year Treasury briefly touched 5% on stronger-than-expected inflation data.
At the same time, Southlake has more standing inventory than it has offered buyers in years, and roughly 44% of active listings have already cut their asking price at least once. Sellers who priced for 2022 are discovering that the market moved without them.
Here is what the numbers actually say, where the public estimates disagree, and what we are telling clients on both sides of the table right now.
September 2026 Southlake snapshot
Figures compiled September 17, 2026 from public sources and NTREIS-based local market reporting. Data windows and city boundary definitions vary by source. All information deemed reliable but not guaranteed.
Average active list price is roughly $3.05 million. Average sold price over the trailing twelve months is roughly $1.69 million.
That gap is the entire story of the Southlake market in September 2026. The pool of homes sitting on the market is priced far above the pool of homes actually closing. The upper tier is stacked up and static. The core of the market, call it $900,000 to $1.8 million, is where transactions are happening.
If you are a seller above $2.5 million, you are not competing with the market average. You are competing with a long shelf of similar homes, many of which have already reduced.
Rates are now the dominant variable, and Southlake feels it harder
Southlake is a jumbo market. With a median in the $1.3 to $1.4 million range, most buyers here borrow well past the 2026 conforming limit of $832,750, which means they are quoted jumbo pricing. The 30-year fixed jumbo rate sat at 7.19% this week, up from 6.85% a week earlier.
The payment math is not abstract. Take a $1.3 million purchase with 20% down, a $1.04 million loan:
- At 6.26%, last September’s average, principal and interest ran about $6,410 per month.
- At 6.95%, this week’s average, the same loan costs about $6,885 per month.
- At 7.19% jumbo pricing, it runs closer to $7,050 per month.
That is $475 to $640 more per month, or roughly $5,700 to $7,700 a year, for the identical house. Mortgage applications fell 4.1% in the week ended September 11, the steepest weekly drop since July.
Buyers feel this immediately. It is why the most productive conversation on a Southlake listing right now is often about a rate buydown rather than a price cut. A seller-paid 2-1 buydown or permanent points can cost a seller less than a $50,000 price reduction while doing more for the buyer’s monthly payment, and it keeps the closed comp higher for the neighborhood.
Inventory, days on market and what sellers are conceding
Southlake inventory is up roughly 21% year over year according to NTREIS-based reporting from local brokerages, with about 193 active listings in 76092. That runs counter to the wider metro, where the Texas Real Estate Research Center found DFW active listings and months of supply both below year-ago levels. The softness is specific to the upper end of northeast Tarrant County, not a metro-wide condition.
Well-positioned Southlake homes are going under contract in roughly 49 to 68 days. Overpriced ones are not going under contract at all. Statewide, unsold inventory at month-end averaged 90 days on market, about 30 days longer than homes that actually sold. Sitting is the failure mode, not selling slowly.
On concessions, the statewide median seller price cut has held at $12,000, about 3.3% of the original asking price. In Southlake, hold that percentage and the dollar figure gets uncomfortable fast: 3.3% of a $1.6 million list price is roughly $53,000. Sellers who plan on one round of negotiation and price accordingly do better than sellers who chase the market down in three reductions.
The Carroll ISD change most market reports are leaving out
On January 12, 2026, the Carroll ISD board voted 5-0 to close Don T. Durham Intermediate School beginning with the 2027-28 school year. The district is moving to a traditional structure: four K-5 elementary campuses and two middle schools serving grades 6 through 8. High schools are unaffected.
Under early planning discussions, Carroll Elementary, Old Union and Rockenbaugh would feed into a combined Dawson and Eubanks middle school campus, while Walnut Grove and Johnson would continue feeding Carroll Middle School. The district has stressed that no final feeder pattern has been approved, that boundaries and transportation routes are being worked out through early 2027, and that sibling grandfathering will be honored.
Three reasons this belongs in a market report and not just a school newsletter.
1. Today’s comps were priced under a boundary map that is changing
Carroll ISD is the reason a large share of Southlake buyers are here at all, and feeder patterns carry real price weight. If you are buying with children in fourth grade or below, ask which middle school the address will feed into in 2027-28, not which one it feeds today. Two homes two streets apart can land on different sides of a line that has not been drawn yet.
2. The enrollment decline is partly a housing supply story
District enrollment fell from about 8,500 students in 2022-23 to under 8,000, with 655 students lost since 2019-20 and campuses running roughly 2,000 students below capacity. Trustee Eric Lannen pointed to a straightforward cause at the January meeting: Southlake has a lot of empty nesters who love it here and are not moving.
That is precisely why the resale pipeline behaves the way it does. Long-tenured owners in Timarron, Monticello and Stone Lakes have low tax basis, often no mortgage or a very cheap one, and no reason to list. Move-up inventory between roughly $800,000 and $1.2 million stays thin while the $2 million-plus tier accumulates. Buyers reading a citywide median as evidence of a soft market are frequently shocked at how little is available in the band they actually want.
3. A 30-acre parcel is about to hit a built-out city
The board plans to sell the Durham campus and its roughly 30 acres, with district finance staff estimating $20 to $25 million. In a city with almost no remaining raw land, a single 30-acre site is a significant event. Whatever it becomes will affect nearby values and traffic patterns for a decade. If you own within walking distance, watch this one closely.
Reading the market by neighborhood
Citywide medians are close to useless in Southlake. Price per square foot spreads between pockets are currently wider than the year-over-year change in the median itself. A rough read on where things stand:
- Timarron. The established master-planned core. Country club adjacency, mature trees, and the deepest resale inventory in the $1.2 to $2 million range. Buyers here are usually weighing renovation cost against new construction.
- Carillon. Newer stock and tighter architectural controls, so price per square foot runs above the citywide figure. Generally holding value better than older inventory at similar price points.
- Clariden Ranch. Larger lots and more custom builds. Buyers price the acreage as much as the finish level, which makes comps genuinely difficult and makes agent judgment worth more.
- Estes Park and Stone Lakes. Larger estate homes, some now 20 or more years old, where updated versus original kitchen and bath work is driving spreads of several hundred thousand dollars between otherwise comparable houses.
- Town Square and the Garden District. Walkability premium, very little turnover, essentially no remaining homesites. A different buyer profile than the rest of the city and a market that behaves almost independently of it.
If you are selling this fall
- Price to the closed comps, not the actives. The active list pool is averaging nearly double the sold average. Pricing against your neighbor’s aspirational listing is the single most expensive mistake available in this market.
- Get the price right in the first three weeks. Homes that sell are going under contract in roughly 49 to 68 days. Homes that reduce twice sit past 90 and then negotiate from a weaker position anyway.
- Offer a rate buydown before you cut price. With jumbo pricing above 7%, buydown dollars buy more buyer enthusiasm per dollar than a price reduction, and they protect the closed comp.
- Finish the deferred work. In a market with 193 alternatives, inspection items become negotiation leverage. Handle the roof, the HVAC and the pool equipment before the buyer’s inspector finds them.
- Do not wait for spring on autopilot. Spring brings more buyers and more competing listings. With inventory already elevated, the fall window has less competition than the March through May stretch will.
If you are buying this fall
- Ask for concessions, in writing, early. Roughly 44% of active listings have already reduced. Seller-paid closing costs, buydowns and repair credits are all live in a way they were not two years ago.
- Shop the loan as hard as the house. Jumbo pricing varies meaningfully between lenders, and portfolio lenders sometimes beat the national averages by a quarter point or more on strong files. On a $1.04 million loan, a quarter point is real money.
- Pull the school feeder question forward. For families with younger children, confirm the 2027-28 middle school picture before you commit, not after.
- Look at the homes that have been sitting. A well-built Southlake house at 120 days on market with two reductions is a negotiation, not a red flag. Find out why it sat. Sometimes it is the price, sometimes it is bad photography, and occasionally it is something worth walking away from.
- Stop waiting for rates. The Mortgage Bankers Association projects 30-year rates between 6.60% and 6.70% through the rest of 2026 and around 6.70% for 2027. Fannie Mae’s outlook is similar. There is no consensus forecast that rewards waiting, and if rates do fall, sideline buyers return all at once.
What we expect through the end of 2026
Nationally, existing home sales slipped 2% month over month in August and fell below a 4 million annual pace for the first time in over a year, while the national median price reached $429,100, its 38th consecutive month of year-over-year gains. Inventory nationally sits at 4.9 months of supply. Texas is at 5.4 months, with June closed sales up 8.6% from a year earlier.
For Southlake specifically, our read:
- Transaction volume stays soft through the holidays, as it does every year, with the added drag of the September rate move.
- The $2 million-plus tier keeps building inventory and keeps cutting. Expect the widest negotiating room at the top of the market, not the middle.
- The core $900,000 to $1.8 million band stays more competitive than the headlines suggest, because empty-nester owners are not creating new supply there.
- Carroll ISD boundary announcements through 2027 will move individual streets more than any citywide statistic will.
This is not a distressed market, but it is a market that requires accurate pricing and real negotiation, which is a different thing entirely.
