Assessment and market value are related—but not identical
Before challenging an assessment, a homeowner should understand the relevant valuation date, local assessment framework and whether market evidence supports a materially different value conclusion.
What we typically review
- property address and assessment information
- relevant tax year or valuation date
- assessor notices or grievance documents supplied by the client
- recent improvements or condition issues
- market sales relevant to the requested valuation date
What an appraisal can contribute
Where appropriate, the appraisal develops a market-supported opinion of value that the client can review with the assessor, attorney or tax representative handling the grievance process.
Start with the municipality's valuation framework
A tax assessment, equalized value and independent market-value opinion are related concepts, but they are not automatically the same number. Before ordering an appraisal, confirm the applicable valuation date, filing deadline, assessment information and local review procedure with the assessor or a qualified adviser. Those requirements determine whether an appraisal can address the question at issue.
The assignment analyzes the subject property and market evidence relevant to the defined date. Physical condition, location, property rights, comparable sales and unusual features may all matter. The appraiser does not file the grievance, promise a reduction or provide legal advice.
When an appraisal may be useful
An independent report can help an owner and adviser evaluate whether market evidence supports a materially different value. It is most useful when the potential issue is large enough to justify the appraisal cost and when the required timeline allows adequate research. See the assessment review guide and official links on our property resources page.
Confirm current procedures and filing dates with the responsible assessor or qualified adviser. The appraisal itself does not file a grievance.
