Frequently Asked Questions
Is my Grantville property tax too high?
The median annual property tax bill in Grantville is $1,728. Using Coweta County's millage rate of 2.321%, the computed tax on the median home ($198,700) is approximately $1,844. If your assessed value is higher than what your home would actually sell for, you are overpaying.
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 within 45 days of your assessment notice.
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 with the 299c freeze. The appeal is free to file and there is no risk of your assessment increasing.
Can my property tax go up if I appeal?
No. Georgia law (O.C.G.A. § 48-5-311) protects you: the county cannot raise your assessed value above what they originally set just because you filed an appeal. The Board of Equalization only rules on the disputed value. Worst case, your appeal is denied and you keep your current assessment -- your taxes will not increase as a result of appealing.
