Experiment takes its unusual name from the agricultural research station that the University of Georgia has operated on its doorstep since the late 1800s, and the community itself is a modest cluster of neighborhoods just north of Griffin in Spalding County. About 3,400 people call it home, and the numbers describe one of the most affordable corners of the county: the typical home is worth about $137,500, nearly 40 percent below the Spalding County median of $228,700. Across Spalding County, the 25th percentile home is worth roughly $151,549 and the 75th percentile roughly $333,413, which means the typical Experiment home is valued below even the county's lower quartile marker. That position matters because Spalding's effective property tax rate is a substantial 1.43 percent, and Experiment's median household income is just $33,333. The result is that the typical household here devotes over 4 percent of its income to property taxes, as heavy a relative burden as you will find anywhere in Georgia. When margins are that tight, an over-assessment is not an abstraction, it is groceries and gas money. Research on assessment accuracy consistently finds that the least expensive homes tend to be valued the furthest above their true market prices, because countywide models calibrate to costlier sales. If any community should scrutinize its assessment notices line by line, it is this one. Georgia allows 45 days from the date printed on the notice to file an appeal, and the appeal itself is free to pursue.
Experiment Appeal Quick Facts
The median home in Experiment is valued at $137,500, and the typical homeowner pays about $1,374 per year in property tax (Census ACS 2024), based on Spalding County's 3.581% combined millage applied to 40% of fair market value after exemptions. That means the typical Experiment homeowner spends 4.12% of household income on property taxes alone. Even though Experiment home values fall below the Spalding County average, the tax burden here is significant relative to household income. A lower home value does not mean your assessment is automatically correct. Overassessments happen at every price point, and correcting one can meaningfully reduce your annual bill. At $137,500, Experiment home values are 40% below the Spalding County median, 19% below Georgia's statewide median of $170,200, 56% below the national median of $318,000.
