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 homeowners get 45 days from the date printed on the annual assessment notice to file an appeal, and in a town this size a handful of real sales can carry the argument.
