Town Center Park, with its big lawn and amphitheater, gives Suwanee a walkable core that most of Gwinnett County's newer suburbs never built, and the surrounding neighborhoods between Duluth and Buford have become some of the most sought-after in the county. The market shows it. Suwanee's typical home is worth about $480,600, roughly 26 percent above the Gwinnett County median of $380,900, and while home values across Gwinnett run from about $289,831 at the 25th percentile to $487,646 at the 75th, much of Suwanee sits at or past the top of that band. Gwinnett's effective property tax rate is about 1.4 percent, and for the city's roughly 22,349 residents, whose median household income is $103,260, property taxes take approximately 4.8 percent of income, one of the heavier relative burdens in the county. Fast-appreciating suburbs create a specific assessment hazard: the county's valuation model chases each year's strongest sales, so a home in an older Suwanee subdivision can get revalued as if it shared finishes and floor plans with new construction a mile away. Owners who bought years ago often assume a rising assessment simply mirrors the market, but the model can overshoot the actual value of a specific house even in a hot one. The assessment notice that arrives each spring is the only official statement of what you will be taxed on, and it starts a 45-day clock. Georgia accepts appeals only within that window, measured from the date printed on the notice.

Check If Your Suwanee Home Is Overassessed
Peachtree Corners leads Gwinnett County in home values, but your individual assessment could still be too high regardless of where Suwanee falls in the county ranking.
With a population of 22,349, Suwanee 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.
