Twenty years ago Grayson was a crossroads town in eastern Gwinnett County; today it is one of the county's most sought after addresses, a small city of about 4,858 people where new subdivisions and a well regarded school cluster pulled home values well past the county norm. The median home in Grayson is now worth about $477,500, roughly 25% above the Gwinnett County median of $380,900. Put that against the county's overall range, which runs from about $289,831 at the 25th percentile to $487,646 at the 75th, and the typical Grayson home is brushing the top quarter of the entire county. Gwinnett's effective property tax rate is about 1.4%, and the typical Grayson household, earning a median of $131,293, commits around 3.3% of its income to property taxes, a meaningful line item even in a comfortable budget. Rapid appreciation created that position, and rapid appreciation is also what strains assessment accuracy: when the assessor's office revalues a fast moving market, homes that look similar on paper get similar values, whether or not one backs to a busy road, needs a roof, or was last updated when the subdivision was built. The gap between a defensible value and an inflated one is often five figures here, which makes the annual notice worth more than a glance. In Georgia you get 45 days from the date printed on that notice to appeal, and the window is the only lever a homeowner has before the value is finalized.
Grayson Appeal Quick Facts
The median home in Grayson is valued at $477,500, and the typical homeowner pays about $4,378 per year in property tax (Census ACS 2024), based on Gwinnett County's 3.506% combined millage applied to 40% of fair market value after exemptions. That means the typical Grayson homeowner spends 3.33% of household income on property taxes alone. Grayson combines higher-than-average home values with a heavy tax burden.
