Buyers looking in southern Denton County face a real choice between Flower Mound, TX and Lewisville.
Key Takeaway
If you want a detached house and your budget reaches Flower Mound's price range, start there. In the last 90 days, 255 of the 259 sales were single-family homes, and sellers are accepting slightly under asking. If you need a townhome, a condo, or a lower entry price, start in Lewisville, because Flower Mound rarely sells those home types.
Who This Guide Is For
You are shopping for a home in southern Denton County and deciding whether to concentrate your search in Flower Mound or Lewisville.
Housing and Price Differences
The real difference between the two is housing type and price point, and it comes from how each one developed. Flower Mound built around large lots, which is why 255 of its 259 sales in the 90 days ending September 30, 2026, were single-family homes. Lewisville built around a wider mix of housing densities.
Flower Mound
Flower Mound's Master Plan sets large minimum lot sizes in its Cross Timbers Conservation Development District. The standard minimum lot area per dwelling is two acres. Conservation developments allow 0.75-acre lots, but only at a maximum density of one home per two acres and with at least 45% of the land set aside as open space.
That land-use approach is why the town is almost entirely detached houses, many of them large. The catch is that if your budget or your needs point toward a townhome or condo, Flower Mound gives you almost nothing to tour.
Lewisville
Lewisville offers a much wider housing mix, including houses, townhomes, condos, and a large rental stock. That variety gives buyers who are priced out of Flower Mound's detached-home market a way in.
What you give up is the uniform large-lot spacing found next door. The lower entry price typically comes with older or smaller homes and more multifamily buildings nearby. Compare year built and square footage listing by listing rather than assuming a Lewisville house is equivalent to a Flower Mound one.
Home Prices and Negotiating Room
In Flower Mound, a typical home sells at 98.4% of its list price. On a home priced around the all-homes median of $642,694, that's roughly $10,300 in negotiating room for the buyer.
With a median 37 days on market and 3.1 months of supply, sellers aren't in complete control. You have time to schedule an inspection and submit a counteroffer without immediately losing the house to a bidding war.
Lewisville offers a lower median starting price, though the exact figure depends on the property type you're targeting. A 20% down payment on a Lewisville townhome requires less cash out of pocket than the roughly $128,500 you'd need for a median-priced Flower Mound house.
Houses vs Townhomes and Condos
Only four of Flower Mound's 259 sales in that 90-day window fell outside the single-family category. That's a small count, not a trend, but it means buyers looking for low-maintenance attached living can't rely on Flower Mound for inventory.
Lewisville's broader mix gives a buyer whose budget sits well below Flower Mound's median more listings to compare. Before making an offer on a condo or townhome anywhere, ask the HOA for current dues and exactly what they cover.
Commuting, Rail Options, and Lake Access
Lewisville has DCTA A-train commuter rail stations inside its city limits: Highland Village/Lewisville Lake, Old Town, and Hebron. These connect to DART for trips toward Dallas, giving Lewisville residents a rail option that Flower Mound doesn't have.
Flower Mound commutes are drive-only, though both cities share the I-35E corridor and sit near DFW Airport. Drive your actual commute at rush hour from each address you're considering before you decide.
Lewisville Lake borders Lewisville's northern edge, with parks such as Lake Park and Tower Bay leased from the US Army Corps of Engineers. Grapevine Lake sits along Flower Mound's southern border, where residents can use Murrell Park. Check FEMA flood maps for any home near either lake to see whether you'll need flood insurance.
Property Taxes, Schools, and Safety
Property Taxes
The Town of Flower Mound's adopted property tax rate for FY 2025-26 is $0.387277 per $100 of assessed value. Lewisville sets its own municipal rate for homes within its city limits. The city rate is only one line on the bill, so look up the total rate and all taxing entities for the exact address on the Denton Central Appraisal District site.
Schools
School assignment depends on the physical address, not the city name on the mailing label, and district boundaries don't line up neatly with city limits. Confirm the assigned schools for a specific address with the district's boundary lookup.
Safety
The Flower Mound and Lewisville police departments report offenses to the FBI Crime Data Explorer and Texas DPS. Citywide rates hide street-level differences, and the two departments may report in different years. Compare the same year and offense categories when researching specific neighborhoods.
How to Choose Between Flower Mound and Lewisville
Answer these three questions in order so you don't spend weekends touring homes in a market that doesn't fit your situation.
Do You Need a Detached House?
If you require a detached house and your budget fits, Flower Mound has the inventory. If a townhome or condo works better, Lewisville gives you options that Flower Mound's market doesn't carry. Settle this before you schedule a single tour, since it can rule out a city entirely.
Is Your Budget Above Flower Mound's Median?
If your ceiling is at or above Flower Mound's median, use the negotiating room described earlier to find a property. If your budget is below that mark, Lewisville's lower entry point is the realistic place to start. A median is a midpoint, not a floor, so run a saved search in each city at your exact price to see real listing counts.
Will You Commute by Train?
If rail access matters to you, the shortlist becomes Lewisville addresses near an A-train station. If you plan to drive, both cities work well, and the decision should come down to home type and price. A station in the city doesn't mean a station near your home, so measure the drive or walk from each listing to the nearest station. If you want help comparing these markets, reach out to Michael Hershenberg to discuss your search.

What Zip Codes Cover Flower Mound and Lewisville?
Each city has its own primary zip codes, but some zip codes cross city boundaries, so a mailing address can name the wrong city. Confirm the city limits on the appraisal district record rather than relying on the mailing address.
