Collin Central Appraisal District
Local Appraisal District
Property owners select O’Connor to represent them in property tax protests more often than any other firm because:
- O’Connor’s aggressive approach is well aligned with the property owners’ interest. We pay the fees and costs regardless of the level of appeal. Many competitors require the property owner to pay the binding arbitration deposit or costs related to judicial appeal such as legal fees, expert witness fees and court costs. We will not ask you to pay any of the costs or fees related to your property tax protest.
- O’Connor has built relationships with appraisal district staff during the last 30 years while conducting literally millions of property tax appeals.
- O’Connor develops an extensive file for each property tax protest, often 50 to 100 pages of evidence regarding both market value and unequal appraisal. Our proprietary software tailors the evidence to a format the appraisal district prefers.
- Our experience has allowed us to compile sales and unequal appraisal data consistent with the format expected by the Collin CAD and the Collin County ARB.
