How to Tell If Your Cook County Property Is Over-Assessed

Every year, thousands of Cook County homeowners pay more in property taxes than they should — not because of fraud, but because assessments are estimates, and estimates drift. Here are three quick checks before you decide to appeal.

1. Compare against similar homes

Pull the assessed values of a few nearby homes of similar size, age, and class. If yours is noticeably higher per square foot, that gap is the heart of a uniformity appeal.

2. Check the physical details

The Assessor works from records that are often out of date. An overstated square footage, a finished basement that isn't, or a bathroom that doesn't exist all inflate your value.

3. Look at recent sales

If comparable homes recently sold for less than your assessed market value implies, that's direct evidence your number is too high.

You don't need to prove all three. One solid angle is often enough to file.

When you're ready, Fair Assessed builds the whole appeal packet for you — comps, forms, and the argument — in a few minutes.
