What homeowners should check before filing
- Verify the property record. Building size, class, age, and other characteristics affect whether another property is a defensible comparison.
- Compare assessments, not just sale prices. A uniformity appeal asks whether similar homes are assessed consistently.
- Favor physically similar evidence. Nearby properties matter, but similarity in class, size, age, construction, and condition matters too.
- Preserve the filing deadline. Official Cook County dates control, even if you are still improving the supporting evidence.
