||Assessors must revalue real property at least once every four years. In some counties, properties are revalued each year and require physical inspection at least once every six years. If your appraised real property value changes, you will receive a "change of value notice" from your local county assessor that lists the old and new appraised value of land and improvements. The frequency of changes in value to your property depends on your county's revaluation cycle. If you do not agree with the appraised value of your property, you are encouraged to contact your local county assessor's office.
