What the rate means here
At 1.43%, Boone County taxes property more heavily than the country as a whole, which sits at 0.98%. Houses here are worth $191,200, below the national $303,400. Part of any high rate is arithmetic rather than policy: a smaller tax base has to be taxed harder to raise the same money.
It ranks #32 of 97 Iowa counties by effective rate, against a statewide 1.43%, and #439 nationally. The state runs from 1.79% in Union County down to 0.92% in Lyon County.
The median home costs 2.4 times the median household income of $79,741, against 3.86 nationally, which is a comfortable ratio by American standards. 81.05% of occupied homes are owned rather than rented, and cheap housing relative to income is usually why. With 26,669 residents, the sample behind these medians is small, and the survey's own margins of error are correspondingly wider.
