What evidence does Cook County Tax Appeal, LLC use?
A successful appeal in Cook County requires more than just a list of nearby homes. At Cook County Tax Appeal, LLC, we build a complete evidence package for every property we represent. Our data-driven approach includes:
Algorithm-Selected Comparables: We use special software to search the Cook County Data Store. This helps us find the best "comparable" properties that show your over-assessment.
CPA-Certified Valuation Reports: Our financial experts create detailed reports that are very important to the Board of Review.
Attorney-Led Legal Arguments: Our legal team creates a formal brief. We cite Cook County Assessor guidelines and important case law to support your reduction.
Commercial Financial Modeling: For commercial and industrial assets, we use advanced financial modeling. This helps us identify differences in income and expenses that traditional tools often miss.
Market Analysis:
We offer information on current market trends and local data. This helps show a lower market value for your property.
The Hands-Off Experience: When you pre-register through our portal, you don't have to gather any of this yourself. We handle everything. This includes checking the Board of Review Dates and filing the final appeal with all the evidence.
