Cook County Assessment Appeal Tool – 6 Comps + Filing Brief ($39)

[David Green]

After my own Cook County reassessment I built a tool that finds nearby similar homes with lower building assessments per square foot.

You get:

• 1 free comparable PIN (email)
• Full set of 6 ranked PINs + a clean Residential Uniformity Brief ready for Board of Review or Assessor filing for $39

The brief includes suggested assessed value, comparison table, portal notes you can copy, and a filing checklist. It does not file the appeal or give legal advice — it just organizes the public data into something you can actually use.
