A number of real property owners across Cook County have been surprised to receive a “Notice of Discovery” from Cook County Assessor Joseph Barrios. The notice informs property owners that the Assessor’s Office believes the property owner may have received one or more improper homeowner exemptions. Basically, the assessor is letting owners know that the assessor’s office will be looking into whether or not improper exemptions were taken and if they were, the assessor will be collecting!
