Free AI Based Comparables for Cook County Property Tax Appeals. Coming soon: DuPage, Lake & Will counties.

This website provides free AI-based comparables to help real estate owners in Cook County appeal their property taxes.

The novelty of this approach is that it uses more data (100 factors) and a more sophisticated algorithm. It also shows if any of the neighbors have been successful with their previous appeals and it displays their agents/lawyers.

If you do not know your Cook County PIN, you can find it here.

To note:
  • This only works with Residential & Condominium PINs (not Commercial).
  • Comps are provided across entire Cook County and there are no constraints on same township, tax code or property class. In other words, the most similar might be in a different township, etc.
  • Certain cookies are required. If you disable them, the site will not function. Consent Preferences
  • This is not tax advice.

We hope you find our service helpful and that it makes the process of appealing your property taxes a little bit easier. If you have any questions or feedback, please don't hesitate to contact us.
