Cook County Board of Review Accepting Real Esate Tax Valuation Appeals from Northfield Township Property Owners


Northfield Township Assessor Patricia Damisch announced that the Cook County Board of Review will be accepting appeals from Northfield Township property owners beginning Monday, December 19th for a four-week period.  

In late July all property owners received new valuations for their properties from the Cook County Assessor. These valuations will stay in place for a three-year period and were based on sales activities in the prior three years. The average assessment increase in Northfield Township was 24%.

Assessing professionals at the Township are available to meet one-on-one with residents to review their properties’ unique situations. An in-house computer system is utilized to find comparable properties to determine whether the owner has a valid case to file an appeal. Staff can then give guidance on how to proceed in the most effective manner.

For further information call (847) 724-8300 to speak to a member of the Northfield Township Assessor’s Department.
