In June 2026, the median sale price in Colleyville's 76034 ZIP code came in at $1,232,500. A year earlier it was $905,500, so June was up about 36 percent. In July 2026, the same ZIP's median was $925,000, down roughly 10 percent from $1,022,500 in July 2025. Both figures come from MetroTex Association of Realtors data published in Community Impact's monthly Grapevine-Colleyville-Southlake real estate reports.
Neither number describes what happened to Colleyville home values. Both describe which homes happened to close that month. The number that has stayed consistent through the summer is new listings, and it points to a Colleyville market that is short on sellers at a time when much of Dallas-Fort Worth has more homes than buyers.
Four Months of 76034, Side by Side
Here is Colleyville's ZIP code across the four most recent months of published data. Each cell shows the 2025 figure first and the 2026 figure second.
| Month | Homes sold | Median sale price | Avg. days on market | New listings |
|---|---|---|---|---|
| May | 43 → 39 | $1,050,000 → $1,025,000 | 28 → 31 | 68 → 58 |
| June | 41 → 44 | $905,500 → $1,232,500 | 25 → 19 | 66 → 49 |
| July | 38 → 35 | $1,022,500 → $925,000 | 46 → 40 | 59 → 41 |
| August | 38 → 25 | $1,035,000 → $1,050,000 | 43 → 26 | 34 → 35 |
The median column swings by $307,500 between June and July 2026. The new listings column fell year over year in May, June and July, then held about level in August.
How a Handful of Closings Moves the Median by Six Figures
A median is the middle sale. In June 2026, with 44 closings in 76034, that meant the average of the 22nd and 23rd sale prices. In August 2026, with 25 closings, it was the 13th. Colleyville's housing stock runs from established homes on smaller lots to estates on an acre or more, so the middle of any given month depends on how many sales from each end landed in that 30-day window.
Swap a few closings from one end for a few from the other, and the median can move by hundreds of thousands of dollars even if no house in the ZIP code changed in value. June 2025's $905,500 and June 2026's $1,232,500 are best read as two different groups of houses. Neither month tells you the market moved by a third.
The same thing happens across the three-city area. In August 2026, 48 of the 128 homes sold across Grapevine, Colleyville and Southlake closed at $1 million or more. Another 29 closed between $700,001 and $1 million, and 42 between $400,001 and $700,000. Those price bands are wide, and the luxury band has no upper limit. A buyer weighing a $1.6 million home and one weighing a $950,000 home are watching different markets that share a single monthly median.
The Line That Moved in One Direction
New listings count how many sellers chose to come to market. That figure doesn't depend on the price mix, and through summer 2026 it moved in one direction in 76034.
From May through August 2025, the ZIP added 227 new listings. Over the same four months of 2026, it added 183, a drop of about 19 percent. Closings fell too, from 160 to 143, or about 11 percent. Supply fell faster than sales.
A home listed in July doesn't always close in July, so comparing the two counts month by month is rough. Over four months, though, the timing gaps tend to even out. Last summer, 76034 recorded about seven closings for every ten new listings. This summer it was closer to eight.
That runs against the regional story. D Magazine's September 2026 market feature describes a Dallas market where "inventory is high, and homes are lingering longer on the market," with many sellers cutting prices and offering concessions. The NTREIS monthly summary for September 2026 shows 31,325 active single-family listings across the DFW metro, 4.3 months of inventory, and 62 days on market.
Fewer Listings, Faster Sales
With fewer sellers in the market, the homes that did list in 76034 sold faster. Average days on market fell year over year in June 2026, from 25 to 19 days, then in July from 46 to 40, and in August from 43 to 26. May was the one month that ran slower, going from 28 days to 31.
August stands out. Colleyville's ZIP recorded 25 sales that month, down from 38 a year earlier. Read alone, that looks like weak demand. The same month's 26-day average on market tells a different story. August's 35 new listings were about level with the 34 recorded a year earlier, and they came after three straight months of year-over-year declines. The homes that did sell moved in under a month. The metro average was 62 days in September 2026.
D Magazine describes this pattern for the broader region. It found that buyer selectivity "concentrates demand into a narrow band of homes that stand out by neighborhood, lot, age, or condition," and concluded that "the market is now rewarding scarcity." The magazine also links buyer hesitation across DFW to mortgage rates more than double what they were five years ago. The data in this post doesn't show why individual Colleyville owners held back. It shows that fewer of them listed, and that their homes sold quickly.
Southlake's Summer Ran Differently
Southlake's 76092 ZIP is the natural comparison. Supply fell there too. New listings went from 271 over May through August 2025 to 211 over the same months of 2026. But days on market rose in three of those four months: May went from 25 days to 33, July from 30 to 41, and August from 44 to 54. Only June was faster, dropping from 46 days to 31.
Southlake's closings also dropped sharply late in the summer, from 55 to 31 in July and from 44 to 25 in August. Its median held in a narrower band, between $1,366,750 in May 2026 and $1,462,500 in June.
Two neighboring ZIP codes, each with fewer sellers, took longer and shorter to sell in late summer. By days on market, Colleyville's supply squeeze showed up in buyer competition more clearly than Southlake's did. For a household choosing between the two, the regional "buyers have leverage" headline applies unevenly, and in summer 2026 it described 76092 more closely than 76034.
What This Means When You Make an Offer
Leverage comes from alternatives. When a Colleyville listing draws interest, how firmly a buyer can negotiate depends on how many comparable homes are likely to come to market in the coming weeks. Through summer 2026, that number was smaller than a year earlier.
For buyers, this changes which data matters on a specific home:
- Recent closings at that home's price and lot size, since the ZIP-wide median mixes very different properties.
- How long similar homes sat before going under contract this summer, measured against 76034's 19-to-40-day averages from June through August 2026.
- How many comparable homes are actively listed right now, which shows whether the shortage still holds for that particular kind of house.
For sellers, the same data cuts the other way. Fewer competing listings help, and the regional mood still shapes buyer expectations. D Magazine reports that DFW sellers are offering price cuts and concessions. Across the metro, single-family homes sold at 93.9 percent of list price in September 2026, according to NTREIS. A Colleyville home that is priced and presented to fit within its own small group of competitors benefits from the shortage. A home priced off the June median doesn't.
Frequently Asked Questions
Is 76034 the same as Colleyville? It's the closest public proxy, but ZIP codes don't follow city limits exactly. These figures also cover all home sales in the ZIP and aren't broken out by property type or luxury price tier.
When will September 2026 data be available? The most recent Community Impact report covers August 2026 and was published September 21, 2026. Reports from this summer came out between the 10th and the 21st of the month after the month they cover.
Does the August sales drop signal falling demand? August's 25 sales came alongside a 26-day average on market, faster than the 43 days recorded in August 2025. That pace doesn't fit a market short on buyers, though one month of a few dozen sales is a small sample in either direction.
If you're weighing a Colleyville purchase or sale against this summer's supply numbers, Sarah Gunnip can put together a valuation built from recent comparable closings in your price range and lot size, not the ZIP-wide median.
