A guide to reviewing your property assessment using publicly available data

Property taxes are based on the value assigned to your property by your local appraisal district. If that value is too high compared to similar homes in your area, you may be paying more in property taxes than necessary.

When this happens, homeowners may have the opportunity to file a property tax appeal.

Signs Your Property Might Be Overvalued

Here are some common indicators that your assessed value may be too high.
