O'Connor & Associates

O'Connor & Associates has been challenging property assessments in Houston and across Texas since 1974. As one of the state's largest property tax consulting firms, we've saved clients over $2 billion in property taxes through strategic appeals and assessment reductions. Our Houston office brings decades of local market expertise to residential and commercial property owners throughout Harris County. We understand the complexities of Texas assessment law and have the resources to handle everything from single-family homes to major commercial portfolios with equal attention to detail.

We provide full-service property tax consulting including assessment protests, valuation analysis, appraisal district hearings representation, and litigation support when necessary. Our services cover all property types: residential homes, office buildings, retail centers, industrial facilities, apartments, and specialized properties like hotels and healthcare facilities. Our team conducts thorough market studies, prepares detailed evidence packages, and represents clients before Harris County Appraisal District review boards. We also handle state-level appeals to the Texas State Office of Administrative Hearings and provide ongoing assessment monitoring services. For complex commercial properties, we offer specialized services like income approach analysis and highest and best use studies.

We start with a complimentary property assessment review to identify potential savings opportunities. Our analysis includes market research, comparable sales studies, and assessment methodology review. If we find grounds for appeal, we'll present a detailed proposal with projected outcomes. Once retained, we file all necessary protests, gather supporting evidence, and prepare comprehensive cases tailored to your property type. We represent you at all hearings and handle appeals to higher levels if needed. You'll receive regular progress reports and copies of all filings. Most cases conclude within the protest year, though complex matters may extend longer.

Our Houston office serves Harris County and surrounding areas including Fort Bend, Montgomery, Brazoria, and Galveston counties. We maintain active practices throughout Texas and handle large commercial portfolios statewide. Our local team understands Houston-area market conditions and assessment practices.
