Heron Bay is not an old Georgia town at all but a master-planned golf community on the southern edge of Henry County near Locust Grove, where about 4,595 people live along fairways and lakes built out largely over the past two decades. Planned communities create a particular assessment problem worth understanding. The median Heron Bay home is worth around $393,000, about 25% above the Henry County median of $313,900, and the typical household earns $106,338, with property taxes absorbing roughly 3.4% of that income. Henry's effective tax rate runs about 1.35%, on the higher side for the southern metro, so valuation errors get amplified. Across Henry County, home values range from roughly $227,073 at the 25th percentile to $398,232 at the 75th, which puts the typical Heron Bay home near the top of the county's spread. Here is the catch with a community like this one. Homes inside a golf development look uniform on an assessor's spreadsheet, but their actual market values diverge sharply based on lot position, golf frontage, and finish level. A blanket rate per square foot will overvalue the homes without premium features while underpricing the ones with them, and if yours is on the wrong side of that math, the error repeats every year until someone challenges it. Georgia law gives homeowners 45 days from the date printed on the annual assessment notice to file an appeal, and Heron Bay values are high enough to make that window worth using.
Heron Bay Appeal Quick Facts
The median home in Heron Bay is valued at $393,000, and the typical homeowner pays about $3,558 per year in property tax (Census ACS 2024), based on Henry County's 3.368% combined millage applied to 40% of fair market value after exemptions.
