Heath Realtor, facts first.

Heath is a city of about 11,671 people (July 2025 Census estimate), mostly in southwestern Rockwall County with a small piece in Kaufman County, and Lake Ray Hubbard forms its western edge. Ninety-eight percent of homes are owner occupied, the median owner-occupied value is $766,900 and the median household income is $220,828 (Census ACS 2020-2024). Zillow's typical home value was about $706,000 in September 2026, down 0.7% from a year earlier, while the median list price was $819,950.

For tax year 2025 a Heath home in Rockwall County paid about 1.59% combined (city 0.27565, Rockwall ISD 1.0669, Rockwall County 0.251 per $100). On a $1.5 million home that is roughly $23,900 a year, or about $1,992 a month, before the state's $140,000 school homestead exemption and Rockwall ISD's additional $20,000 over-65 exemption. A parcel in the small Kaufman County portion carries Kaufman County's 0.334478 county rate instead, which would put the combined rate near 1.68% with the same city and school rates.

Ask for 12 months of water bills and the irrigation zone map, and check which watering days apply to the address, because Heath's water supply rules shape what an acre lot costs to maintain. If you are comparing a new build to a resale, add HOA or municipal management district costs, such as those in Heath Golf and Yacht Club, to the monthly math.

The lesson in Heath is water. The city buys its supply through Rockwall from the North Texas Municipal Water District, paused new development for six months in late 2023 to secure more supply and set irrigation rules, and now runs a twice-a-week watering schedule against a supply of 6.5 million gallons a day. On a one-acre lot that shapes what landscaping you can keep green, so ask about irrigation design and water bills before you buy, and treat drought-tolerant landscaping as a selling feature.

New homes from $1 million in Bristol Valley and Heath Golf and Yacht Club are your competition, so a resale needs to show why it is the better value: mature trees, a larger lot or a lake view. Fix what a buyer's inspector will flag on an older home (roof, HVAC, irrigation leaks, foundation movement on clay soil) and keep the receipts. With Rockwall County listings at a median of 67 days on market in September 2026, a clean, well-priced first impression matters.
