How it works

Step 1

We analyze your property

Your assessment is compared against recent arm's-length sales of similar commercial properties to determine if you're paying too much.

Step 2

We prepare and file your appeal

We generate a professional evidence package with comparable sales, market analysis, and a written brief, then file it with the Cook County Assessor.

Step 3

You save on your tax bill

Our fee is 30% of first-year tax savings, billed only if the appeal succeeds. No reduction means no charge. Zero risk.

Frequently asked questions

Is there any risk to filing an appeal?

No. Your assessment cannot be raised as a result of filing an appeal. The worst case outcome is no change. There is zero downside risk to appealing.

What does it cost?

Nothing upfront. Our fee is 30% of first-year tax savings, billed only if we successfully reduce your assessment. If we don't save you money, you pay nothing.

Typically 6-8 weeks from filing to the Assessor's decision. Filing windows are approximately 30 days per township, with 4-5 townships opening each month.

Do I need a lawyer?

Not for Assessor-level appeals. If escalation to the Board of Review is warranted, we partner with licensed Illinois attorneys at no additional cost to you.
