    What actually wins an appeal in Illinois

    Now, in Illinois you don't win by arguing what your house would sell for. You win by showing that homes pretty much like yours, nearby, are assessed lower per square foot than yours is. The state appeal board asks for at least three comparable homes, and if you sit above their range you have a case. If you're inside the range or below it, honestly, no amount of paperwork changes the answer.

    Should you appeal in Kenilworth?

    Honestly, for most people the answer is no, and we'd rather tell you that than have you find out the hard way. The only real question is whether your home sits above the range for similar homes near you. Our free check reads Cook County's own records, runs that same per square foot comparison, and tells you straight which side you're on. Most people who use it get told not to bother.

    How we know this

    We took every 2024 house appeal in the Cook County Assessor's published appeals dataset and matched each property's PIN to its address in the Assessor's addresses dataset, so these are Kenilworth's own numbers rather than its township's. Houses are classes 202 through 210, 234 and 278. A win means the certified value came in below the value the county mailed out. We only publish a town with at least 150 decided cases, because a rate built on fewer honestly isn't worth trusting.
