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.

O’Connor measures its success in client property tax savings, not billings. Our goal is to save clients $1 billion annually.
With over 200 property tax experts, many of whom have worked with us for 10+ years, O’Connor has the expertise to help with your property tax questions and appeals. We literally wrote the books on property tax reduction:
- Mass Appraisal for Commercial – What Every Commercial Property Owner Should Know!

The steps to appeal are complicated and may seem like too much work, but when O'Connor represents your property for appeal, we handle the details. We provide a property tax reduction service to residential homeowners in exchange for a contingency fee of 30 percent of all property taxes saved through administrative hearings or judicial appeal, for that tax year.
