The evidence
This parcel is assessed at $350.14/sqft. The median for comparable homes in 60004 is $296.58/sqft — 18% above the neighborhood comp set.
This property was purchased for $380,000 in February 2023 — an arm's-length market transaction that directly benchmarks the assessment.

Fair cash value = certified assessed value × 10 (Illinois law: residential properties assessed at 10% of FCV).
What it means
In plain terms: your home is assessed higher than comparable nearby homes, which means your annual property tax bill is likely higher than it should be. You have the right to challenge it.
Two independent signals point to overassessment: your property's assessed value is higher per square foot than comparable homes nearby, and it was assessed above what you paid for it in 2023. That combination is strong evidence to bring to a Board of Review hearing.
