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, you can appeal. Georgia law sets the appeal deadline at 45 days from the date of your assessment notice. The date printed on your notice controls. Confirm with your county before you file.

Is your Locust Grove property tax assessment too high?
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.

If Henry County has overestimated your home's fair market value, you are paying more than you should. Filing is free, and the Board of Equalization can lower your value but cannot raise it above the county assessors' figure, except on a value already frozen by an earlier appeal. 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.

What evidence matters for Locust Grove appeals?
In a mid-size city like Locust Grove, you should be able to find 3-5 comparable sales within Henry County. Look for homes that sold in the last 12 months with similar square footage, age, and condition. If local sales are limited, expand your search to neighboring areas within the county.

How much can you save in Locust Grove?
Based on a combined tax rate of 3.368%. Your actual rate may vary by tax district. Three-year figures are estimates and apply only if your value is reduced; you can then keep saving for up to three years, subject to the statutory exceptions.
A 10% reduction on the median Locust Grove home ($307,300 down by $30,730) would save approximately $414 per year, or $1,242 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.
At 4.04% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.

How much of my income goes to property taxes in Locust Grove?
At the median, Locust Grove homeowners pay 4.04% of their household income ($75,083/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
How do Locust Grove property taxes compare to Heron Bay?
Heron Bay leads Henry County with a median home value of $393,000, compared to Locust Grove's $307,300. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Locust Grove property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Locust Grove's median home ($307,300), the assessed value is $122,920. Multiply by Henry County's millage rate of 3.368% to get your annual bill. Many Locust Grove homeowners find that assessed values have climbed faster than actual sale prices. Comparing your value to 3-5 recent sales of similar homes is the quickest way to spot an overassessment.
Is it worth appealing a small overvaluation in Locust Grove?
Yes. Even a $134 per year overcharge (from a $10,000 overvaluation at Henry County's 3.368% rate) adds up to $402 over three years (estimated); if an appeal removes it, the 299c freeze can keep that saving for up to three years, subject to the statutory exceptions. The appeal is free to file, and the Board of Equalization cannot raise your value above the county assessors' figure, except on a value already frozen by an earlier appeal.
Can my property tax go up if I appeal?
Losing at the Board of Equalization cannot raise your value, with one exception. Under O.C.G.A. § 48-5-311(e)(9), the Board of Equalization, a hearing officer, or an arbitrator can lower your value but cannot raise it above the value the county assessors set. The exception is a value already frozen by an earlier appeal: on an appeal filed while that freeze is in effect, the Board is not capped and could raise the value. That limit applies to the deciding body; the county assessors can still make changes or corrections to your value when they review your appeal.
