What Does It Actually Cost to Buy a Home in Heath, Texas in 2026?

The median home in Heath sold for $749,592 over the three months ending June 2026, up 5.5% from the same period a year earlier, at a median of $223 per square foot, according to Redfin's Heath market data. That is roughly $260,000 above the median in neighboring Rockwall and nearly double the median in Rowlett, two cities within a fifteen-minute drive.

That gap is not an accident of taste or timing. It is written into Heath's zoning ordinance, and once you understand that, the rest of this market makes sense.

The price floor is in the code, not the market

Most Dallas-area suburbs set a minimum lot size and let the builder decide how much house to put on it. Heath sets both.

Under § 159.21 of the Heath Code of Ordinances, the SF-43 single-family district — the classification covering the majority of the city — requires a minimum lot of one full acre (43,560 square feet) and a minimum dwelling of 3,200 square feet. The front setback is 50 feet. A garage whose doors face the street has to sit 75 feet back from the front property line. Maximum building coverage is 35% of the lot.

Read that again: you cannot legally build a 2,000-square-foot house on a Heath acre in SF-43. The ordinance forbids it. So the entry point into most of Heath is an acre of land plus a minimum of 3,200 finished square feet, before anyone has chosen a single finish.

Smaller-lot options exist — SF-22 at 22,000 square feet and SF-15 at 15,000 — and those districts hold Heath's more attainable inventory. But the SF-43 acre is the default, and it produces a $750,000 median in a city of roughly 12,100 people.

Heath's 2025 Comprehensive Plan reaffirmed that direction. The city has grown from 9,744 residents at the 2020 census to an estimated 12,103 in 2026, per World Population Review, toward a projected build-out near 25,000. The lot sizes are not expected to shrink on the way there.

What the market actually feels like right now

Here is where the story turns, and where the median price alone will mislead you.

Heath is currently one of the slower markets in the eastern Metroplex. Redfin scores it 27 out of 100 on competitiveness — "not very competitive." The specifics behind that score:

Two numbers do the heavy lifting. Median days on market rose 30 days year over year, to 84. And 43.6% of Heath listings took a price cut. The average Heath home sells about 4% below list and goes pending in roughly 76 days.

At the same time, sales volume is up nearly 40%. Both things are true: more homes are trading, and they need substantially more time and more price movement to get there. That is the signature of a market where inventory has caught up to demand and the initial ask is frequently wrong.

The recent closings show it plainly. A four-bedroom on Cedar Glen Trail closed in August after 328 days. A home on Kings Pass took 282 days, one on Long Irons Court 209. Meanwhile Brentwood Drive went in 30 days and Laurence Drive in 29. The spread between a correctly priced Heath home and an aspirationally priced one is measured in seasons, not weeks.

The geography: a lake, a farm road, and two counties

Heath sits on the southwestern shoulder of Lake Ray Hubbard, about 25 miles east of downtown Dallas. The lake defines the west and north edges of the city, and the shoreline drives the top of the price range — the recent $1,895,000 sale on Blue Heron Lane and the $1,365,000 on Brentwood Drive both sit in that orbit.

FM 740 is the spine, running north to south and carrying most of Heath's traffic — the city posts TxDOT construction updates for the corridor, worth checking before you commit to a specific stretch of it. Commercial life is deliberately concentrated at the Heath Towne Center district around FM 740, Laurence Drive, and Smirl Drive, a comprehensive-plan decision made specifically to keep retail from spreading along the farm roads. The city is finishing a $12.8 million renovation of Towne Center Park, adding pickleball courts, an interactive fountain, and a stage. Terry Park on the lake provides a public boat ramp and courtesy docks, which matters for buyers who want water access without paying for waterfront.

Recognizable subdivisions include Buffalo Creek, built around a golf course, and Stoneleigh. Street names tell you where you are: Cedar Glen, Blue Heron, Mallard Crossing and Wood Duck cluster toward the water; Kings Pass, Legend Drive and Bay Crest Trail sit inland in the platted acreage developments.

The two-ZIP problem

This is the single most common thing buyers get wrong about Heath. The city is primarily in Rockwall County (ZIP 75032), but extends south into Kaufman County, where addresses carry the 75126 ZIP shared with Forney. Buyers regularly assume a 75126 Heath address is really a Forney address, or that a Heath address automatically means Rockwall ISD. Neither assumption is safe.

School assignment in Texas is set by attendance boundary, not ZIP code or city name, and Rockwall ISD's boundary covers all or part of Rockwall, Heath, Fate, McLendon-Chisholm and Rowlett without tracking any city limit. If assignment matters to your purchase, verify it at the specific address with the district directly — not from the listing sheet, and never from the ZIP. The City of Heath maps page is a useful starting point for city and county boundaries. The county split has a second consequence: your appraisal district, tax rates, and protest deadline all follow the county, not the city.

What it costs to carry

Heath's city council adopted a property tax rate of 27.565 cents per $100 of taxable assessed value for FY 2025-26, down about 5.1% from the prior year, as reported by the Rockwall Herald-Banner. That is a low municipal rate by DFW standards, and it is genuinely part of Heath's pitch.

But the city rate is the smallest line on a Texas tax bill. The school district rate is the largest, with county, county road, and any special districts stacked on top. Pull your exact combined rate for a specific parcel from the Rockwall Central Appraisal District, or Kaufman CAD if the property sits on the Kaufman County side, rather than estimating from the city rate alone.

One carrying cost that never shows up in a mortgage calculator: the same FY 2025-26 budget raised water and sewer rates by roughly 24%, driven by North Texas Municipal Water District costs and a bond issue funding the city's Water Bridge Plan. On an acre lot in a North Texas summer, irrigation is not a rounding error. Ask any Heath seller what they pay in July.

How Heath compares to what is next door

Source: Redfin, as-of dates noted

Rockwall gives you a larger city, more retail, more inventory, and a median roughly $260,000 lower — on lots a fraction of the size. Rowlett puts you closer to Dallas across the lake at a lower price point, again on conventional suburban lots. Forney, over the Kaufman County line, is the volume new-construction market.

What Heath sells that none of them do is the acre. If land, separation, and a large house on a large parcel are the point of the move, Heath is the local answer and the price reflects that scarcity. If they are not the point, you are paying a premium for something you will not use. Redfin's early-2026 migration data shows 83% of Heath home searches originating inside the DFW metro, so most of this demand is North Texas move-up traffic rather than out-of-state relocation.

For sellers, the 84-day median and 43.6% price-cut rate mean Heath in 2026 requires a real pricing strategy, not a hopeful list price and a plan to reduce later. Every cut here is public, and buyers above $700K read days-on-market history before they read the photos.

Frequently Asked Questions

Why are homes in Heath, Texas so expensive compared to Rockwall?

Zoning, mostly. Heath's SF-43 district requires a minimum one-acre lot and a minimum 3,200-square-foot dwelling under § 159.21 of the city code, a combination neighboring cities do not impose. Heath's June 2026 median of $749,592 against Rockwall's $489,728 is largely a land-and-square-footage difference, not a per-foot premium — Heath ran $223 per square foot in the same period.

How long does it take to sell a house in Heath in 2026?

The median was 84 days as of June 2026, up 30 days year over year, with the average home going pending in about 76 days and selling around 4% below list. Correctly priced homes still move in under a month; several August 2026 closings went pending in 29 to 30 days, while overpriced listings sat 200 to 300 days. Roughly 44% of listings took at least one price reduction.

Is Heath in Rockwall County or Kaufman County?

Both. The majority sits in southwestern Rockwall County under ZIP 75032, but the city extends south into Kaufman County, where addresses carry the 75126 ZIP shared with Forney. That determines which appraisal district values your property, which rates apply, and where you protest. Confirm the county on the specific parcel before relying on any tax estimate.

What are the property taxes like in Heath?

The city adopted 27.565 cents per $100 of assessed value for FY 2025-26, down about 5.1% year over year — low by DFW standards, but only one line. The school district rate is typically the largest piece of a Texas bill, with county and special districts on top. Pull the full combined rate for your parcel from Rockwall CAD, or Kaufman CAD for the southern portion of the city. Heath also raised water and sewer rates roughly 24% in the same budget, a real cost on acre lots.

Should I use an agent who specifically knows Heath, or is any Dallas agent fine?

In Heath, local knowledge does real work. Three things reward it: the SF-43 rules that determine what can be built or added on a given lot, the Rockwall–Kaufman split that changes the tax picture across a boundary the city limit does not follow, and a market where a third of a year on market is the median rather than a red flag. An agent who does not know those three will misprice a Heath listing and misread a Heath comp.
