O'Connor Associates worked with the Collin County Assessor to reduce our assessed property values, which led to reduced property taxes.

I appreciate your correspondence regarding the county home tax initiative. Your e-mails described the process and eventual results. I must admit that I know little about the process and Intend to get up to speed with the various elements.

I have used O’Connor and Associates for three houses. They communicate well and it’s a streamlined, painless process for me. I only pay if they are able to get a reduction in my appraised value.

Notified O'Connor & Associates that I wanted to engage them to protest my property taxes. One email and off they went. They were able to get a significant reduction in my taxes! Thank you!
