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 law sets the appeal deadline at 45 days from the date of your assessment notice, and the appeal itself is free to pursue. The date printed on your notice controls.

Is your Experiment property tax assessment too high?
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.
How does Experiment compare to other Spalding County cities?
Griffin leads Spalding County in home values, but your individual assessment could still be too high regardless of where Experiment falls in the county ranking.
What evidence matters for Experiment appeals?
In a mid-size city like Experiment, you should be able to find 3-5 comparable sales within Spalding 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 Spalding County Property Tax Guide.
How much can you save in Experiment?
Based on a combined tax rate of 3.581%. 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 Experiment home ($137,500 down by $13,750) would save approximately $197 per year, or $591 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.
At 4.12% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.

Frequently Asked Questions
Is my Experiment property tax too high?
The median annual property tax bill in Experiment is $1,374 (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 Experiment property tax?
Appeals are filed with the Spalding 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 Experiment?
At the median, Experiment homeowners pay 4.12% of their household income ($33,333/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
Are Experiment homes undervalued compared to Spalding County?
Experiment'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 Experiment property taxes compare to Griffin?
Griffin leads Spalding County with a median home value of $220,900, compared to Experiment's $137,500. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Experiment property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Experiment's median home ($137,500), the assessed value is $55,000. Multiply by Spalding County's millage rate of 3.581% to get your annual bill. Many Experiment 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 Experiment?
Yes. Even a $143 per year overcharge (from a $10,000 overvaluation at Spalding County's 3.581% rate) adds up to $429 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.
