What the rate means here
At 0.69%, Cobb County taxes property more lightly than the national 0.98%. This is the case where the rate misleads. Owners pay $2,560 a year, which is what matters, and the low percentage is a function of what housing is worth rather than of restraint by the county.
It ranks #129 of 150 Georgia counties by effective rate, against a statewide 0.81%, and #1,776 nationally. The state runs from 1.40% in Clinch County down to 0.35% in Fannin County.
The median home costs 3.79 times the median household income of $98,712, close to the national 3.86. Incomes here run above the national median, which is what keeps that ratio ordinary despite the house prices. With 769,152 residents this is one of the larger counties in the country, so the medians here average across a genuinely varied housing market and hide a lot of local range.
