Kennesaw was still called Big Shanty in 1862, when Union raiders stole the locomotive General from its depot and set off the Great Locomotive Chase; the engine now sits in the Southern Museum downtown, a block from the railroad tracks that still bisect the city. Modern Kennesaw is a college town of about 34,600, home to Kennesaw State University and to neighborhoods that stay noticeably more affordable than Cobb County's east side. The median home value here is about $335,400, nearly 18% below the Cobb County median of $407,200. Across Cobb, values stretch from roughly $299,081 at the 25th percentile to $586,625 at the 75th, and that imbalance is worth remembering when your notice arrives: models calibrated county-wide can pull Kennesaw values upward toward the county's pricier submarkets. Cobb's effective property tax rate is comparatively moderate at about 1.21%, but with median household income at $83,356, Kennesaw homeowners still put around 3.2% of income toward property taxes. Student-rental demand near campus adds another distortion, since investor purchases can push recorded sale prices above what an ordinary owner-occupied house would fetch on the open market. None of this means your assessment is wrong, but it means the conditions for error are present, and the only way to rule it out is to set your notice next to recent sales of homes that genuinely match yours. Georgia gives every property owner 45 days from the date printed on the annual assessment notice to appeal, and checking your number costs nothing but attention.
Kennesaw Appeal Quick Facts
The median home in Kennesaw is valued at $335,400, and the typical homeowner pays about $2,630 per year in property tax (Census ACS 2024), based on Cobb County's 3.015% combined millage applied to 40% of fair market value after exemptions. That means the typical Kennesaw homeowner spends 3.16% of household income on property taxes alone. Even though Kennesaw home values fall below the Cobb 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 $335,400, Kennesaw home values are 18% below the Cobb County median, 97% above Georgia's statewide median of $170,200, 5% above the national median of $318,000.
Check If Your Kennesaw Home Is Overassessed
Smyrna leads Cobb County in home values, but your individual assessment could still be too high regardless of where Kennesaw falls in the county ranking.
With a population of 34,605, Kennesaw has plenty of recent sales to draw from. The strongest evidence is 3-5 comparable sales: homes similar to yours in size, age, and condition that sold recently for less than your assessed value. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.

Based on a combined tax rate of 3.015%. Your actual rate may vary by tax district.
A 10% reduction on the median Kennesaw home ($335,400 down by $33,540) would save approximately $404 per year, or $1,212 over three years with the 299c value freeze.
At 3.16% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.
