Am I over-assessed — and is it worth it?
How do I know if my Cook County home is over-assessed?
You are over-assessed when your assessment is high relative to comparable properties — the “uniformity” standard the appeal system uses. In practice: compare your assessed value per square foot to similar nearby homes. If yours is materially higher than your neighbors’ median, you have a case.
Measured across the public roll, about 120,000 Cook County dwellings sit far enough above their peers to be strong appeal candidates. Whether your specific home is one of them is a per-parcel question — check your address to see your assessment against comparable homes.
