Austell grew up as a railroad junction in the 1880s, and freight trains still roll through the middle of this south Cobb County town of about 8,447 people, a short drive from Six Flags Over Georgia. Housing has stayed comparatively affordable: the median home is worth about $284,900, roughly 30% below the Cobb County median of $407,200. In fact, across Cobb County home values climb from about $299,081 at the 25th percentile to $586,625 at the 75th, meaning the typical Austell house is priced beneath the bottom quarter of that range. That is exactly the situation where county-wide appraisal models are least reliable, because the sales data behind them comes mostly from pricier submarkets in east Cobb, Smyrna, and Marietta. The good news is that Cobb's effective property tax rate, about 1.21%, is gentler than much of metro Atlanta, and with a median household income of $72,938 the typical Austell homeowner spends a moderate 1.9% of income on property taxes. A moderate burden is not a reason to accept an inflated value, though. Austell's older housing varies house by house, in condition, in renovation, in flood history near Sweetwater Creek, and a model that misses those differences carries the error forward year after year. Read your assessment notice against real sales in your own neighborhood rather than the county as a whole. Georgia gives homeowners a 45-day window from the notice date to appeal, and once it closes, the value stands until next year.
