Must You Disclose a Prior Appraisal in a Cook County Board of Review Appeal?

A taxpayer submitting an appraisal to the Cook County Board of Review should expect the Board to examine other recent valuation work for the property. Under current Rule 19, taxpayers must disclose and submit appraisals or other estimates of value prepared within three years before the January 1 lien date, regardless of whether they were created for financing, estate, insurance, management, or another purpose.

The requirement prevents an appeal from presenting one valuation in isolation while omitting a recent report that reached a different conclusion. A prior appraisal does not automatically decide the assessment, but it must be identified and addressed when the rule applies.

Which prior appraisals must be disclosed?

The Cook County Board of Review official rules require disclosure of an appraisal or other estimate of value prepared within the three years before the January 1 lien date. The stated examples include financing, estate, and insurance reports, but the rule is not limited to those purposes.

The key questions are when the report was prepared, what property and interest it valued, the effective valuation date, and whether it is an appraisal or another estimate of value. Owners should inventory reports early rather than waiting until the evidence deadline.

Does a bank appraisal count?

A financing appraisal is expressly included in the Board’s rule. Even if the bank ordered the report and the owner did not choose the appraiser, the report may be part of the required disclosure. The intended use of the appraisal does not make it irrelevant to the filing obligation.

Obtain a complete copy when possible, including the certification, assumptions, property description, comparable data, photographs, and valuation approaches. A summary page or remembered value is not enough to evaluate how the report relates to the appeal.

What if the prior appraisal value is higher than the requested value?

A difference should be explained, not hidden. The reports may use different effective dates, property rights, occupancy assumptions, conditions, renovation plans, income data, or market evidence. A financing appraisal may also serve a different intended use. Those differences can matter, but they need to be identified specifically.

An appeal brief should explain why the current evidence better reflects the relevant January 1 value or why a prior conclusion should receive different weight. A bare assertion that the earlier appraisal was for the bank is unlikely to resolve a material conflict.

What if the prior appraisal value is lower?

A lower prior value may support the appeal, but it still needs to be evaluated for date, scope, assumptions, and property interest. A report can be favorable in amount yet weak for the tax-year question. The most useful submission connects the report’s evidence to the requested assessment rather than relying on the conclusion alone.

What appraisal standards does the Board require?

Rule 19 states that submitted appraisals must comply with USPAP, Illinois appraiser licensing law, and recognized valuation principles. The appraiser should be competent in the property type. The report should identify the subject and comparable PINs, use relevant market data, and include a highest-and-best-use analysis as of the January 1 lien date.

The rule also addresses dated photographs, maps, cap rates, income-approach analysis for many income-producing properties, and PDF submission. Compliance does not guarantee that the Board will accept the conclusion; the assigned analyst determines the report’s weight case by case.

How should commercial owners organize recent valuation reports?

Create a three-year inventory before the appeal is drafted. Include appraisals, broker opinions, internal valuations, insurance estimates, estate work, purchase-related reports, financing analyses, and any other document that may qualify as an estimate of value. Record the author, report date, effective date, purpose, property interest, value conclusion, and location of the complete file.

Then compare each report with the proposed appeal evidence. Flag differences in building area, rent, vacancy, expenses, capitalization rates, renovations, lease-up assumptions, highest and best use, and parcel coverage. Resolve factual inconsistencies before filing.

Does the disclosure rule apply only to commercial property?

Rule 19 is not written solely for commercial property, but the issue is especially common in commercial appeals because owners may commission reports for loans, acquisitions, estate planning, insurance, or internal asset management. Residential owners with recent appraisals should also review the rule rather than assume the report can be omitted.

What happens if a prior appraisal is not disclosed?

The Board’s rule states that failure to disclose required reports may result in exclusion of the appraisal submitted with the appeal. More broadly, an incomplete record can undermine credibility and prevent the reviewer from understanding material differences among valuations.

That risk is a reason to begin evidence review early. It is not a reason to avoid a meritorious appeal. A complete submission can acknowledge a prior report, explain its purpose and assumptions, and show why the requested assessment follows from the relevant evidence.

When should the disclosure analysis happen?

Perform it before the complaint and evidence are finalized. The township complaint deadline and evidence deadline may be different, and late evidence is generally not accepted without a recognized exception. Waiting until the final day can leave no time to obtain a report or reconcile conflicting data.

Use the Cook County deadline tracker to identify the current filing stage, then confirm the official Board calendar and rules.

How can an attorney help with prior appraisal disclosure?

Counsel can determine which reports appear responsive to the current rule, coordinate with the appraiser, align the property and PINs, and explain differences in dates, rights, assumptions, and evidence. The goal is a candid record that supports the requested assessment without overstating what any one report proves.
