The process

From first look to final reduction

01
Preliminary review
Public assessment data is run against current market benchmarks. If the numbers suggest over-assessment, a full income analysis is warranted - at no cost to find out.
No cost, no commitment
02
Income analysis
A full direct capitalization analysis is performed using your actual rent roll and expense data, normalized to market. This is the standard Michigan Tax Tribunal methodology, prepared by a MAI-credentialed consultant.
MAI-credentialed valuation
03
MTT petition
If the analysis supports an appeal, a formal petition is filed with the Michigan Tax Tribunal by the May 31 deadline. Michigan commercial owners may bypass the Board of Review entirely.
Attorney-filed petitions
04
Settlement
The large majority of cases settle before a formal hearing. Fees are contingency-only - a percentage of actual tax savings achieved. No reduction means no fee, ever.

Why 2026 matters

Proposal A creates a compounding problem for commercial owners.

Under Michigan's Proposal A, taxable value is capped at 5% or CPI annually - but resets to assessed value at every ownership transfer. Properties that haven't been appealed since acquisition frequently carry assessed values that no longer reflect current market conditions. Detroit's effective mill rate of approximately 85 mills amplifies every dollar of over-assessment into significant annual cash cost. The May 31 MTT deadline is absolute - no extensions, no exceptions, no retroactive remedies.
