What the payment actually costs
Illinois property tax averages 2.27% of value — 2nd highest of 51 states, against a national average near 1.10%. On a $400,000 home that is about $9,080 a year, or $757 a month added to principal and interest.
Homeowners insurance runs about $1,480 a year in Illinois, 25th of 51 states and below the $1,552 national average. Together, tax and insurance add roughly $880 a month to the payment before you have paid a dollar of principal.
How this fits the rest of your tax bill
Illinois taxes both income and property, so neither side offsets the other. Property tax at 2.27% ranks 2nd of 51, and state income tax applies on top. Model both together when comparing against a no-income-tax state, because the comparison flips depending on how much house you buy relative to what you earn.
Property tax rates are effective statewide averages; your county assessor sets the actual figure and it varies widely within a state. See our methodology.
