What evidence wins a property tax appeal in Dunwoody?
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. In Dunwoody, there are typically enough recent sales to build a strong case. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.
Why is my Dunwoody property tax bill so high?
The median tax bill in Dunwoody is $5,454 -- 279% above Georgia's statewide median of $1,439. This reflects both higher home values and DeKalb County's combined millage rate. If your individual assessment is higher than what your home would actually sell for, you are paying even more than necessary.
Can my property tax go up if I appeal?
No. Georgia law (O.C.G.A. § 48-5-311) protects you: the county cannot raise your assessed value above what they originally set just because you filed an appeal. The Board of Equalization only rules on the disputed value. Worst case, your appeal is denied and you keep your current assessment -- your taxes will not increase as a result of appealing.
