Drivers on I-75 know Locust Grove for its outlet mall exit, but the town itself, at the southern end of Henry County, has multiplied in size over two decades as subdivisions replaced pastureland along the corridor south of McDonough. Roughly 10,500 people live here now, and the housing market has essentially converged with the county's: the median Locust Grove home is worth about $307,300, within 2 percent of the Henry County median of $313,900. Do not let that averageness make you complacent about your assessment. Henry County's effective tax rate, about 1.35 percent, is on the higher side for the southern metro, and the typical Locust Grove household, with median income at $75,083, gives about 4 percent of income to property taxes, a heavier load than most Georgia homeowners carry. In a town where whole neighborhoods went up in bursts, mass appraisal has a particular failure mode: the model prices your house off sales of near-identical floor plans, but it cannot see the drainage problem in your backyard, the bonus room the builder counted as finished space, or the lot that backs up to truck traffic feeding the distribution warehouses. Across Henry County, home values range from roughly $227,073 at the 25th percentile to $398,232 at the 75th, and where your house genuinely sits in that range is a question the county answered with a formula. If the answer looks high, Georgia allows 45 days from the date printed on that notice to file an appeal.
Locust Grove Appeal Quick Facts
The median home in Locust Grove is valued at $307,300, and the typical homeowner pays about $3,030 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. That means the typical Locust Grove homeowner spends 4.04% of household income on property taxes alone. If Henry County has overestimated your home's fair market value, you are paying more than you should. Georgia law guarantees that filing an appeal cannot increase your assessment, so there is no risk in checking. At $307,300, Locust Grove home values are 2% below the Henry County median, 80% above Georgia's statewide median of $170,200, 3% below the national median of $318,000.
