Grantville grew up along the railroad in southern Coweta County, an old mill town of about 3,250 people that sits closer to the Meriwether County line than to the booming subdivisions around Newnan. Its housing market tells that story plainly. The median Grantville home is worth about $198,700, some 44 percent below the Coweta County median of $357,500, and one detail is worth sitting with: across Coweta County, home values run from roughly $245,853 at the 25th percentile to $483,337 at the 75th, which means the typical Grantville house is worth less than the county's 25th percentile home. That mismatch matters at assessment time. Coweta's appraisal models are calibrated on a county dominated by newer and far more expensive housing, and older homes in small towns are exactly the properties a countywide model understands least, whether that means a century-old mill house, a renovated farmhouse, or a brick ranch on a double lot. Coweta's effective tax rate is low, around 0.93 percent, and Grantville households at a median income of $69,283 spend about 2.5 percent of income on property taxes, so a bad assessment will not ruin anyone. It will keep overcharging you each year you let it stand, though, and in a market this thin the county has few local sales to correct itself with. Georgia law sets the appeal deadline at 45 days from the date of your assessment notice, and in a town this size a handful of real sales can carry the argument.

Is your Grantville property tax assessment too high?
The median home in Grantville is valued at $198,700, and the typical homeowner pays about $1,728 per year in property tax (Census ACS 2024), based on Coweta County's 2.321% combined millage applied to 40% of fair market value after exemptions.

If Coweta 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 $198,700, Grantville home values are 44% below the Coweta County median, 16% above Georgia's statewide median of $170,200, 37% below the national median of $318,000.

Turin leads Coweta County in home values, but your individual assessment could still be too high regardless of where Grantville falls in the county ranking.
What evidence matters for Grantville appeals?
In a mid-size city like Grantville, you should be able to find 3-5 comparable sales within Coweta 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. For the full evidence strategy, exemption details, and step-by-step filing instructions, see our Coweta County Property Tax Guide.
How much can you save in Grantville?
Based on a combined tax rate of 2.321%. 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 Grantville home ($198,700 down by $19,870) would save approximately $184 per year, or $552 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.
At 2.49% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.

Frequently Asked Questions
Is my Grantville property tax too high?
The median annual property tax bill in Grantville is $1,728 (Census ACS). If your assessed value is higher than what your home would actually sell for, you are paying more than that. Compare your assessed value to recent sales of comparable homes nearby.
Who do I contact to appeal my Grantville property tax?
Appeals are filed with the Coweta County Board of Assessors, not at the city level. File a PT-311A form. 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.
How much of my income goes to property taxes in Grantville?
At the median, Grantville homeowners pay 2.49% of their household income ($69,283/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
Are Grantville homes undervalued compared to Coweta County?
Grantville's lower median does not mean the county's assessment of your specific home is correct. Overassessments happen at every price point. Compare your assessed value per square foot to actual recent sales of similar homes nearby.
How do Grantville property taxes compare to Turin?
Turin leads Coweta County with a median home value of $590,900, compared to Grantville's $198,700. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Grantville property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Grantville's median home ($198,700), the assessed value is $79,480. Multiply by Coweta County's millage rate of 2.321% to get your annual bill. Many Grantville 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 Grantville?
Yes. Even a $92 per year overcharge (from a $10,000 overvaluation at Coweta County's 2.321% rate) adds up to $276 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.
