To dispute the assessed value of your property, start by reviewing the assessment notice sent by your local tax assessor. Check whether the assessor has made any errors, such as using incorrect property details (e.g., square footage or the number of rooms). Next, compare your property with similar homes in your area (called "comparables" or "comps") to ensure the assessed value aligns with the market value of similar homes. If you believe there is a significant discrepancy, you can file an appeal with your local tax assessor’s office, providing evidence of overvaluation, such as a professional appraisal, or comparable sales data. An in-person hearing may be required to present your case.
