Thank you for sharing your concern. We understand your frustration. Unfortunately, the village is not able to take any action in regards to residential property assessments.
You’ve taken the right step by filing an appeal through the Cook County Assessor. You may also want to consider asking for a re-review.
You can also file an appeal to the Illinois Property Tax Appeal Board http://www.ptab.illinois.gov/
Please note the appeals will be accepted until August 28, 2017.
