- 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.
How comparable properties support a Berwyn appeal
The Board of Review recommends using similar properties with lower assessments for lack-of-uniformity cases and generally suggests several similar properties. Simple Tax Appeal evaluates Cook County parcel and assessment data to help homeowners narrow the evidence instead of treating every nearby property as a useful comp.
