Before the Bulloch County Board of Commissioners acted Tuesday to hold its millage rate unchanged and keep the revenue resulting from a small overall increase in property values, the Board of Education voted Aug. 11 to roll back its portion of the millage to offset the value inflation. For property owners whose assessed values did not rise, the net result of the commissioners’ and school board’s opposite actions will be a tiny tax increase. It works out to 50 cents more for the year on a home with a market value of $125,000.
