Lewisville’s citywide median sale price sits almost exactly at $400,000 — half the city sells below it, half above, and a citywide comparison tells you close to nothing about your house. If your listing expired here, there is a good chance it was priced against a number that describes a completely different part of Lewisville.
The city median is the wrong number for your house
Three independent sources land in the same narrow band: $400,000 for the three months ending June 2026, $389,500 for July 2026 sales, and $395,000 over the trailing 30 days in August 2026.
Now look at what that one number is averaging together. Castle Hills posted a median home price of $775,000 and an average sale of $859,126 as of July 2026. Valley Vista runs around $530,000, while established neighborhoods south of FM 407 have entry points below $300,000 — same city limits, same school district.
That is roughly a half-million-dollar internal spread, and a median calculated across it describes no real house. It is also the mechanism behind a large share of expired Lewisville listings: the seller, the agent and the appraiser were each working from a different slice of the city, and nobody noticed until the house had sat for a month.
The other direction costs just as much. In March 2026, Flower Mound’s median was $625,000 and Highland Village’s was $596,657. A Lewisville seller looks at those and prices toward them. But the reason buyers shop Lewisville at all is that it is a $100,000 to $200,000 saving against Coppell or Flower Mound. Price like Flower Mound and you have erased the only reason the buyer was standing in your kitchen.
Where the $400K to $1M homes actually are
Lewisville covers 43.22 square miles, 6.21 of it water, across ZIP codes 75057, 75067 and 75077, with portions extending into Dallas County. The $400,000-and-up market clusters in a few nameable places rather than spreading evenly:
- Castle Hills — the flagship, and on its own it spans this entire price band. A 2,568-acre master-planned community of more than 18,000 residents, annexed into Lewisville on November 15, 2021; higher-spec construction, mostly 2000s and 2010s.
- Valley Vista — the clearest secondary tier, around $530,000.
- Vista Ridge — newer construction, and one of the most-listed neighborhoods alongside Castle Hills, Creekside and Valley Ridge.
- Lewisville Valley, Highlands, Meadow Lake and Valley Ridge — mixed. Updated homes clear the floor; original-condition homes often do not.
- South of FM 407 and much of the older 75057 core — generally below the band.
The build-era spread is why the neighborhood matters more here than in most Denton County cities. The median year built is 1997, but the bulk of the stock dates from 1970 to 1999, with another 20.1% added in the 2000s and 19.2% in the 2010s — Lewisville was already near 25,000 residents by 1980. Two listings a mile apart can be a 1976 brick ranch on an established lot and a 2016 build with modern systems. No citywide statistic survives that.
Why Lewisville listings stall
Your listing may name a school that no longer exists
Lewisville ISD voted to close five elementary schools and redraw boundaries for the 2025–26 school year: Creekside, Polser STEM Academy, Highland Village, Garden Ridge and B.B. Owen. The capacity math behind it was 47,711 students enrolled against an optimal capacity of 62,508 — 15,907 empty seats, and the closures were projected to save about $2.3 million, roughly $460,000 per campus.
Creekside Elementary sat in the Lewisville High School feeder, and its closure moved students across Lewisville, Lakeland and Degan elementaries. This landed on Lewisville proper, not only the outlying feeders. So if your house was listed in 2024 or 2025, the marketing may name a campus that has since closed, or a zone that has since changed — and neither you nor your agent would necessarily have known. As of December 2025 the district was still outlining program relocations, so this is ongoing rather than settled. The contrast a few miles north runs the other way: in Corinth, Lake Dallas ISD recently completed high school renovations and added a Career and Technical Education building. One district is consolidating buildings; the other is adding them.
Even before the closures, “Lewisville ISD” was never one answer. The district contains five high schools — Flower Mound, Hebron, Lewisville, Marcus and The Colony — two of them physically in other cities, and Castle Hills addresses are typically in the Hebron feeder. Buyers filtering for one campus screen out homes that qualify and tour homes that do not.
Castle Hills buyers are running old tax numbers
Before annexation, Castle Hills sat in its own municipal utility districts with rates running from $0.69 per $100 in District 1B up to $1.00 in the newest districts, against Lewisville’s $0.436. Effective October 1, 2022, the city rate replaced them and most Castle Hills residents saw a decrease at the city level; Lewisville’s FY2025–26 rate is $0.419009 per $100.
Do the arithmetic a buyer does not. On a $775,000 home, the difference between an old $1.00 rate and the current $0.419009 is roughly $4,500 a year — about $375 a month of payment capacity. A buyer working from a stale online estimate disqualifies themselves before they ever call. Two related items belong in the listing: whether a Public Improvement District assessment applies in the newer sections, which has to be confirmed property by property, and the fact that Castle Hills sits inside Lewisville city limits without carrying a Lewisville postal address, so those listings can drop out of “Lewisville, TX” searches entirely.
Flooding here comes from creeks, not just the lake
The City of Lewisville is explicit that flooding occurs primarily around creeks draining to the Elm Fork of the Trinity — Timber Creek, Prairie Creek and Denton Creek on the west side, Midway Branch and Indian Creek on the east. These flood on heavy rain even when the lake and river hold steady. Timber Creek Acres has had repeated problems; in September 2010, Tropical Storm Hermine rainfall pushed water to the 100-year floodplain and the city planned to buy out homes and build a park. The city also warns that silting has reduced Timber Creek’s drainage capacity, so without action FEMA could redraw an enlarged floodplain map. Separately, the Lewisville Dam carries a USACE Dam Safety Action Classification of 2, “high urgency,” as of the March 6, 2026 fact sheet, with $150 million in safety modifications behind it. Your buyer will find that headline. Have the flood determination and elevation certificate ready before a lender raises it in week six.
New construction here competes for your buyer, not with your house
Old Town Lewisville has more than 1,500 new residential units within a ten-minute walk of Main and Mill across seven projects — among them Aura Old Town, Legacy Pointe, Brownstones at West Walters and Harris Street Townhomes. That product is attached rather than detached, so it is not a like-for-like rival to your house. It absorbs the buyer instead: the entry-level and downsizing pool that would otherwise shop older detached Lewisville homes at the bottom edge of your band. Meanwhile the former Vista Ridge Mall, now “The Vista,” has a $200 million redevelopment announced but no development agreement on record as of February 2026 and no construction as of mid-2026. Sellers nearby price in the announced upside; buyers discount for what is there.
Condition, spread across five decades of building
Because the stock runs from the 1970s forward, condition here is a per-address variable rather than a citywide story. Polybutylene supply piping was installed roughly from 1975 to 1996 and Lewisville’s build curve sits across that whole window; cast iron sewer lines deteriorate from the inside out, long before anything is visible; in the oldest stock, aluminum branch wiring is worth having an inspector check for rather than assuming either way; and Denton County spans both expansive Eagle Ford clay and the sandier Woodbine formation within a few miles, so a 1976 slab here has been through roughly fifty years of shrink-and-swell cycles.
Roof age follows the same pattern. The insurance squeeze is countywide — Texas premiums up 21% in 2023 and 19% in 2024, Denton County averages commonly over $4,000 a year, wind and hail deductibles typically 2%, older roofs sometimes covered only at actual cash value. But because Lewisville roofs were not all installed in the same few years, sellers here get blindsided one at a time rather than as a group. The answer is a pre-list insurance quote on your address, not an assumption about the city.
What this means for your relaunch
Relisting in Lewisville starts with refusing the citywide number. Comps have to come from your neighborhood and your price tier, because Castle Hills and the older core are not the same market and an appraiser will not treat them as one. Then the school information gets re-verified and stated correctly, since the boundaries genuinely changed. Then the searchable items — flood determination, tax rate, any district assessment, roof and insurance — get resolved before the listing goes live rather than during a buyer’s option period.
None of that is about listing again harder. It is about fixing the specific things that made the first attempt fail. If you want to understand what happened, start here, or book a re-evaluation at no cost. If you would rather begin with the number, send the address and Meredith will run comps for your specific neighborhood.
Every figure above is cited to its source with the period it covers, and Lewisville’s published figures vary between sources because they measure different windows and different geographies. When Meredith prices your house she works from current NTREIS data for your specific neighborhood and price band — not from a citywide Lewisville average, which for most homes here describes something other than what you own.
