Tax Appeal Appraisals in Chicago Metro Area

Challenge Your Assessment with Confidence

A tax appeal appraisal is an independent, certified property valuation used as evidence to challenge a county assessor's over-inflated assessment and reduce your property tax burden in Cook, DuPage, Kane, Lake, McHenry, Will, and Kankakee Counties.

Property taxes are a significant expense for homeowners, and they are based on the county assessor's estimate of your home's value. Unfortunately, these mass-appraisal assessments are often inaccurate because the county cannot physically inspect every home. If your home is assessed higher than its actual market value, you are paying too much in taxes.

To successfully appeal your property tax assessment, you need overwhelming evidence. The most powerful tool you can bring to an appeal board is an independent, professional appraisal conducted by a certified local appraiser.

How We Help with Tax Appeals

• Thorough Inspection: We document the actual condition, features, and any negative influences affecting your property that the county may be unaware of.
• Accurate Comparables: We carefully select the most similar recent sales in your immediate neighborhood, rather than relying on automated mass data.
• Persuasive Evidence: Our reports are highly detailed and clearly explain our valuation methodology, making it difficult for the appeal board to dispute.

The Tax Appeal Process: What to Expect

Understanding the appeal timeline helps you act before your county's deadline:

1. Review Your Assessment: When you receive your Notice of Value from the county, compare the assessed value to your home's actual market value. If it appears inflated, an appeal may be warranted.
2. Order an Independent Appraisal: Contact us at 312-647-2498 or request a quote online. We schedule an inspection—typically 30–60 minutes—and deliver a certified report within 7–10 business days.
3. File the Appeal: Submit your appeal to the county board of review along with our appraisal report as supporting evidence. Deadlines vary by county but are typically within 30–60 days of receiving your assessment notice.
4. Attend the Hearing: If required, you (or your representative) present the appraisal evidence before the appeal board. Our reports are prepared to hold up under scrutiny.
