Burton Township assessments are a bit lower than the 33.3% three-year average mandated by the state law I apologize for helping craft.
(I wanted to make it a one-year average so people could understand the process better, but the Illinois Farm Bureau argued that because of farm purchases for Galena Territory that using a one-year average would force up farm assessments through Jo Daviess County. Ironically, in a couple of years, the same organization got a law passed that basically ignored market value. Productivity of the land is now used for farm assessments.)
In any event, since Burton homes and businesses are assessed at a three-year average of 31.81%, residents can expect to have them raised by a factor which will bring them up to 33.#% of market value.
The measure of uniformity, the margin of error (Coefficient of Dispersion) in Burton Township is a low 8.62%.
