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.
  • 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. Let us know how to improve or if you want custom (with specific factors as constraints) comparables.
