How many Flower Mound homes sit on an acre or more, and what do they cost?

Acre-plus homes in Flower Mound are concentrated on the west side, in the 75022 ZIP code, where the town's SF-E estate zoning sets a one-acre minimum lot and the Cross Timbers Conservation Development District governs most of what's left to build. Expect to pay a real premium: Wichita Creek Estates, one of the town's established acre-plus areas, has run a median around $1,475,000 over the trailing twelve months against a citywide median sale price near $650,000. The bigger surprise is contractual. If the land carries an agricultural valuation, the standard TREC residential resale contract says nothing at all about rollback taxes, and that silence lands on the buyer.

If you've been running the "1 acre" filter on Zillow and Redfin and getting different answers, you're not doing it wrong. On the same day this was written, Redfin returned five Flower Mound homes matching one acre at a $680,000 median, while Zillow returned twenty-three for the same city and the same filter. Redfin's separate land-and-lots view showed twenty-one listings at a $725,000 median.

Those are three different answers to one question, and none of them is a count of homes that actually sit on an acre.

That matters more here than it would in most towns, because Flower Mound's acreage stock is small, geographically concentrated, and governed by rules that don't apply to the rest of the market. Here's what's really out there, what it costs, and the three things that catch acreage buyers late in the deal.

Where the acre-plus homes actually are

Almost all of it is west of FM 2499, in 75022. That's not an accident of taste. It's zoning.

Flower Mound's SF-E, single-family estate district is written for detached homes on lots of one acre or larger, and it caps lot coverage at 25 percent of the site. So an acre-plus lot in Flower Mound is usually acre-plus by ordinance, not because a builder chose to be generous.

The established pockets you'll actually shop:

• Wichita Creek Estates. Homes here average north of 4,400 square feet and typically sit on more than an acre. Median sale price over the trailing twelve months has run about $1,475,000, with homes going under contract in roughly 17 days.
• Hidden Valley Country Estates. Adjacent acreage stock, older and more varied in age and condition than Wichita Creek.
• Chateau du Lac. A gated 160-acre enclave along the north shore of Lake Grapevine, where lots run to 2.25 acres and up.
• True rural parcels. The larger tracts west and north, where a listing like 4088 Chimney Rock Drive, a 10-acre property, shows what the top of this market looks like.

Set that against a citywide median sale price of $649,611 as of May 2026, and the shape of the premium is clear. You are not paying 10 or 15 percent more for land in Flower Mound. In the established acre-plus areas you're often paying north of twice the citywide median, and most of that spread is the dirt, not the house.

More acreage is coming, slowly, and on purpose

The Cross Timbers Conservation Development District covers the western part of town and still holds more than 1,500 acres of undeveloped land. The town's master plan allows residential development there two ways: two-acre lots across an entire site, or a conservation layout that permits one-acre lots if half the land is preserved as open space. A November 2022 zoning change added a floor, requiring 25 percent of a development to be at least one acre and setting a minimum lot size of 0.75 acres.

Translated: Flower Mound has decided, deliberately, that its remaining west-side land will not be subdivided into quarter-acre lots. That's why acreage supply here stays tight and why it holds value the way it does. It's also why the status of a project like Eden Ranch matters to anyone shopping this segment.

What an acre actually lets you do

This is where expectations and ordinance part ways more often than anything else.

That 25 percent SF-E lot coverage cap is a real constraint. On a one-acre lot, 25 percent of 43,560 square feet is 10,890 square feet of coverage for everything: house footprint, garage, covered patio, detached shop, barn. That's generous for a house. It gets tight fast once someone starts sketching a 2,000 square foot workshop behind an existing 5,000 square foot single-story.

A few other things worth confirming before you're emotionally committed:

• Recreational vehicles, trailers, and boats. Flower Mound's town code limits these in residential districts by size and requires screening, and those limits apply whether or not the property has an HOA. Acreage does not exempt you.
• Trees. Flower Mound has a tree preservation ordinance, and protected trees generally can't be removed without going through the town. On a wooded west-side acre this can shape where a pool, shop, or drive can physically go. Get the specifics from the town before you plan around a clearing.
• Deed restrictions. Plenty of acreage tracts carry recorded restrictions with no active association to enforce them. No HOA is not the same as no rules. The restrictions show up in the title commitment's Schedule B, and they are worth reading during the option period rather than after.
• Animals. Rules on livestock and fowl vary by lot size and district. Verify with the Town of Flower Mound for your specific address rather than relying on what a neighbor down the road is doing.

The rollback tax your contract probably doesn't mention

This is the one that costs real money, and it is the single most overlooked item in Flower Mound acreage deals.

Plenty of larger parcels here carry an agricultural valuation, which taxes land on its productivity value rather than its market value. It is a large annual saving, and it is conditional. Under Texas Tax Code Section 23.55, when the land's use changes to a non-agricultural use, the owner who changes the use owes a rollback tax: the difference between what was paid under ag valuation and what would have been owed at market value, for each of the three preceding tax years. That lookback was five years until House Bill 3833 shortened it to three, effective June 15, 2021.

Simply stopping the agricultural use counts as a change of use. So does building on it.

Now the part almost nobody checks. The TREC One to Four Family Residential Contract, form 20-19, contains no rollback tax provision at all. Paragraph 13 of that form is titled "Prorations," and it addresses current-year taxes, interest, rents, and dues. The words "rollback tax" do not appear anywhere in the form.

Compare that to the two TREC forms written with land in mind. In both the Farm and Ranch Contract and the Unimproved Property Contract, Paragraph 13 is titled "Prorations and Rollback Taxes," and 13B allocates the risk explicitly: if the sale or the buyer's use after closing triggers additional assessments for periods before closing, they are the buyer's obligation, and if they're triggered by the seller's use or change in use before closing, they're the seller's.

So here is the practical trap. A house on ten agricultural acres in Flower Mound is a residential property, and it is very often written on the 1-4 residential form, because that's the form that fits the improvement. That form is silent on rollback taxes. Silence is not protection. It just means the allocation was never negotiated, and the party who changes the use after closing is the one the appraisal district looks at.

If you're buying acreage with an ag valuation, this needs to be a deliberate decision before you sign, not a discovery in your second year. Whether the right answer is a different form, a special provision, an escrow holdback, or simply confirming with Denton CAD that the valuation is being maintained depends entirely on what you plan to do with the land. This is exactly the kind of question I walk clients through before we write the offer, and it's one of the few places in a Texas contract where the standard form genuinely does not cover you.

Water and septic: who's actually in charge

Generic Texas articles get both of these wrong for Flower Mound, and the errors point buyers to the wrong phone number.

Septic. Denton County Public Health's Environmental Health Division administers on-site sewage facilities in the unincorporated parts of the county. Inside Flower Mound town limits, the Town of Flower Mound is the TCEQ-authorized agent and handles permitting and inspection itself, under regulations it adopted in 2010. Its own environmental health specialists serve as the designated representatives who do plan reviews, inspections, and system evaluations. When a property with a septic system sells, the permit is transferred to the new owner, so ask for the system's planning materials and permit history rather than assuming a home inspection covered it. A standard inspection generally does not evaluate a septic system.

Wells. Denton County sits in the North Texas Groundwater Conservation District, which covers Collin, Cooke, and Denton counties. This gets misreported as Upper Trinity constantly. Household and livestock wells, and new wells producing under 17.36 gallons per minute, are exempt from metering, production reporting, production fees, and permitting. They are not exempt from registration. New wells must be registered before construction begins, so if a property has a well, confirm it's on record with the district and ask for the driller's log, depth, and any recent water quality testing.

And the survey question gets sharper with acreage. Longer boundaries mean more chances for a fence, a drive, or a neighbor's outbuilding to sit in the wrong place. Whether you need a new survey is worth deciding early on a large tract, because the answer changes what you can object to and when.

Frequently Asked Questions

How many homes on an acre or more are for sale in Flower Mound right now?

Portal counts disagree sharply. On the same day, Redfin showed five Flower Mound homes matching a one-acre filter while Zillow showed twenty-three, and Redfin's land-and-lots view showed twenty-one. The filters key off different fields and none of them is a verified count of homes on an acre-plus lot, so the reliable number comes from an MLS search run on lot size and confirmed against the recorded plat.

Why are acre-plus homes in Flower Mound so much more expensive?

Supply is capped by zoning rather than by demand. The SF-E estate district requires one-acre minimum lots, and the Cross Timbers Conservation Development District steers remaining west-side land toward one-acre and two-acre layouts with open space set aside. Established acre-plus areas like Wichita Creek Estates have run a median near $1,475,000 against a citywide median around $650,000, and most of that gap is land value rather than house size.

Will I owe rollback taxes if I buy land with an agricultural exemption?

You will if you change the use. Texas Tax Code Section 23.55 assesses the difference between the agricultural valuation and market value for the three prior tax years against whoever changes the use, and ceasing agricultural activity counts. The TREC One to Four Family Residential Contract does not address rollback taxes at all, so on a house-plus-acreage deal the allocation has to be negotiated deliberately rather than assumed.

Who permits a septic system in Flower Mound?

The Town of Flower Mound, not Denton County. The town is the TCEQ-authorized agent for on-site sewage facilities inside its limits and employs the designated representatives who handle permits, plan review, and inspections. Denton County Public Health covers the unincorporated areas of the county instead.

Does a home on an acre in Flower Mound have to have an HOA?

No. A number of acre-plus properties, particularly older west-side tracts, have no association at all. Recorded deed restrictions can still apply without an association to enforce them, and town ordinances on things like trailers and recreational vehicles apply regardless. Check the title commitment's Schedule B for what's actually recorded against the property.

Can I keep horses on an acre in Flower Mound?

It depends on the lot size and the zoning district, and the rules are specific enough that a neighbor's setup is not evidence of what you're allowed to do. Confirm the answer for your exact address with the Town of Flower Mound during the option period, before the land use you're planning becomes a reason you overpaid.

Before you write the offer on acreage

Acreage in Flower Mound is a genuinely different purchase from a subdivision home, and the differences are mostly invisible until they're expensive. The lot coverage cap shapes what you can build. The ag valuation shapes what you'll owe. The well and the septic system shape what you inspect and who you call. None of it shows up on a listing page.
