Terms of Service, Delivery & 100% Refund Policy

Effective Date: October 21, 2026

1. Scope of Service (Self-Guided / Pro Se Data Research)

Cook County Tax Appeals provides residential comparable property assessment uniformity and comparable sales research packets ("Evidence Packets") for properties located in Cook County, Illinois. Our Evidence Packets are prepared solely for the property owner's own self-represented (pro se) filing with the Cook County Assessor's Office or the Cook County Board of Review.

No Legal Representation or Appraisal: Cook County Tax Appeals is not a law firm, does not employ attorneys to represent customers, does not file appeals on behalf of third parties, and does not provide legal advice or certified real estate appraisals. The homeowner remains solely responsible for submitting their own appeal prior to their township's official filing deadline.

2. Pricing & Digital Delivery

  • Standard Residential DIY Appeal Evidence Packet ($49.00 USD one-time flat fee): Covers 1 Cook County Class 2 single-family, townhome, or condo PIN. Delivered digitally via email and secure web/PDF report link within 12 hours of purchase (typically within 1–2 hours).
  • Multi-Unit (2–6 Flats) & Priority Rush Appeal Evidence Packet ($79.00 USD one-time flat fee): Covers Class 2-11 (2-to-6 unit apartment buildings), multi-PIN residential properties (up to 3 associated PINs), or priority 2-hour rush delivery.

There are no recurring subscriptions, hidden fees, or contingency percentages.

3. 100% Reduction-Case Money-Back Guarantee & Refund Policy

We stand behind our comparable data analysis with a straightforward refund policy:

  • No-Comp / Fairly-Assessed Full Refund: If we audit your property's Assessor Neighborhood Code and Property Class and cannot identify at least three (3) comparable properties assessed at a lower building $/sq ft (or comparable sales supporting a lower market value), we will notify you and issue a 100% full refund of your $49 or $79 payment.
  • Satisfaction & Cancellation: If you request a cancellation before your Evidence Packet is delivered, or if there is any factual error in your packet that we cannot promptly correct, you are entitled to a full refund upon emailing marisol@placeholderdomainname.com or calling (312) 847-1916.
  • Outcome Disclaimer: Assessment reduction decisions rest within the statutory discretion of the Cook County Assessor and the Cook County Board of Review. While our packets follow county uniformity standards, no specific dollar reduction can be guaranteed by any party.
