Property Tax Protection Program Benefits
  • No flat fees or upfront costs. No cost ever unless your property taxes are reduced.
  • All practical efforts are made every year to reduce your property taxes.
  • Never miss another appeal deadline.
  • Property taxes protested for you annually.
  • You do not have to accept the appraisal district's initial guesstimate of value.
  • We coordinate with you regarding building size / condition to avoid excess taxes.
  • Free support regarding homestead exemptions.
  • Some years are good - typically 6 to 7 out of 10 will result in tax reduction for you.
  • The other 3 to 4 years out of 10 we strike out. Most often due to people issues in the hearing process. Some years we get an easy appraiser at the informal; some years someone who is impossible to settle with.
