About the Union Property Market
Union is a city located in Cass County, Michigan. Every property inside the Union city limits is assessed by the Cass County assessor, which applies Michigan property tax rules uniformly across the county.
Because Union property values are set at the county level, the same assessment rules apply to homes throughout the city. Homeowners who believe their Union home is over-assessed have the right to file a appeal directly with Cass County.
Michigan allows the assessor to defend or adjust the assessed value during a appeal, so Union homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Union Property Market Context
The property tax picture in Union is shaped as much by Michigan statewide policy as by anything unique to a city.
Michigan market character
Michigan caps annual increases on the "Taxable Value" of your home at the lesser of 5% or inflation (Proposal A), but uncaps the value when the property sells. That means newly purchased homes often see dramatic assessment jumps, which is where most successful protests happen.
How Michigan handles appeals
Michigan homeowners appeal first to the local Board of Review in March, then the Michigan Tax Tribunal. Small-claims cases are simple and effective.
When to file in Union
Board of Review meets in March, and this is the only window to appeal the assessed value for the year. Tax Tribunal filings follow by July 31.
Common Union Property Types
Union homeowners typically file protests across these property categories:
Single-family homes
The most common residential type and the dominant protest category.
Condominiums
Common in denser parts of the city and near employment centers.
Townhouses
Attached-home neighborhoods in newer subdivisions.
Small multi-family
Duplexes and 2-4 unit buildings assessed as income property.
Commercial
Retail, office, and small commercial along major corridors.
ProtestMax supports all of the above property types in Union. Each appealpacket is tailored to the property's classification and uses comparable sales from Union and surrounding Cass County neighborhoods.
