Devine Intervention: Shedding Light on Illinois Property Tax

When the System Misses: Why Assessments Don’t Always Match Reality


Listen Later

Episode Summary

In this episode, Attorney Nora Devine sits down with Bob Becker, a seasoned Illinois commercial appraiser, to break down the cost approach to property valuation—a key yet often misunderstood method used in property tax appeals. Bob explains how this approach differs from the sales comparison and income methods, when it’s most useful (especially for special-use properties), and the biggest challenges appraisers face when applying it. Together, they explore real-world examples—from farmland to libraries—and discuss how external factors like construction costs and local market data can influence property tax values.

This conversation sheds light on how assessors, taxpayers, and attorneys can use the cost approach more effectively to ensure fair assessments and better outcomes in Illinois tax cases.
