What the rate means here
At 2.49%, McHenry County taxes property more heavily than the country as a whole, which sits at 0.98%. Both the rate and the house are above national. That is the expensive combination, and the $7,153 median bill reflects it.

The median home costs 2.79 times the median household income of $102,836, against 3.86 nationally, which is a comfortable ratio by American standards. 82.58% of occupied homes are owned rather than rented, and cheap housing relative to income is usually why.
