Bremen Township appeals: common questions

What are the odds an appeal in Bremen Township works?

Those are township-wide rates from closed cases, not a prediction for any one property.
Should I appeal to the Assessor or the Board of Review in Bremen Township?
They are separate filings and the table above shows both. For 2025, Bremen Township sent 3,449 residential appeals to the Assessor and 5,455 to the Board of Review; 11.1% and 36.2% of them respectively moved the value. The Board of Review hears appeals after the Assessor has closed a township, so missing the first window does not end the year.
How much did assessments go up in Bremen Township?
At the 2026 reassessment the median residential assessment rose 19.2%, measured across the 40,880 class-2 properties the Assessor valued in both 2025 and 2026. That is the middle of the township, not your property: half the homes moved more.
