What are the eligibility requirements for a Cook County property tax appeal?
Most properties qualify if the Assessor's value exceeds true market value. Qualifying factors: overvaluation, lack of uniformity vs. comparable properties, property data errors (square footage, units, classification), hardship (deferred maintenance, vacancy, fire damage), or—for commercial—income/expense discrepancies.
