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.
