How much of my income goes to property taxes in Dunwoody?
At the median, Dunwoody homeowners pay 4.47% of their household income ($121,903/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
Why are Dunwoody home values higher than the DeKalb County average?
Dunwoody's premium reflects demand driven by school quality, proximity to employment centers, and neighborhood amenities. Higher values mean a larger potential overassessment -- a 10% overvaluation costs approximately $1,056 per year in excess taxes.
How do Dunwoody property taxes compare to Brookhaven?
Brookhaven leads DeKalb County with a median home value of $692,700, compared to Dunwoody's $602,900. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Dunwoody property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Dunwoody's median home ($602,900), the assessed value is $241,160. Multiply by DeKalb County's millage rate of 4.379% to get your annual bill. In growing cities like Dunwoody, reassessments often outpace actual market conditions -- compare your assessed value per square foot to recent closed sales within 1 mile of your home.
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.
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.
