O'Connor & Associates review · 2026
O'Connor reviews: what O'Connor actually costs in 2026
O'Connor & Associates is a legitimate, long-established Texas property tax firm with decades of ARB and litigation experience, and it charges nothing upfront. Its residential fee is about half of your first-year tax savings. The detail most comparisons get wrong: that fee does not recur. You pay it once, in the year they win a reduction, not every year afterwards. That makes O'Connor genuinely cheaper than a recurring-percentage service like Ownwell if you hold the house for years, and considerably more expensive than a flat-fee packet in the year you appeal. Which is right for you depends entirely on how long you plan to own the home.
What 5 years of protests costs you
Drag to your annual tax savings. Contingency firms charge a cut of your savings every single year. We charge a flat fee and you keep all of it.
Assumes you protest every year for 5 years: our $49 protest kit each year, Ownwell at a contingency fee starting at 25% of savings per year (ownwell.com pricing example, retrieved June 2026), and O'Connor at 50% of current year savings per their published residential terms (poconnor.com, retrieved June 2026). Ownwell's rate varies by region, so we use their own 25% example as the conservative case.

Is O'Connor legit? Yes, without qualification
O'Connor & Associates has operated in Texas for decades, handles residential and complex commercial property at scale, and has real experience in front of appraisal review boards and in litigation. It charges no upfront fee and states plainly that you pay nothing unless it reduces your taxes. There is no legitimacy question here, and anyone telling you otherwise is selling something. The only question worth asking is what the fee costs you against the alternatives.
The part other comparisons get wrong
O'Connor takes about half of your FIRST-YEAR savings. Many comparison pages, including some written by its competitors, imply that cut repeats annually. It does not. On a $1,155 annual reduction you pay roughly $578 once. Ownwell, at 25% in Texas, takes about $289 every single year you keep the reduction. Over five years that is roughly $578 to O'Connor against roughly $1,444 to Ownwell. Over a long hold, the firm with the scarier headline percentage is the cheaper one.
Where the flat-fee packet wins, and where it does not
Our packet is $49 once and you keep every dollar of the reduction, so on the same $1,155 saving you are about $529 ahead of O'Connor in year one and further ahead every year after. That is the honest case for doing it yourself. The honest case against: you file it, you attend the hearing, and you argue it. O'Connor does all of that for you, and for an owner who will not show up to an ARB hearing, a reduction won by someone else beats a packet that stays in the inbox. If you want it handled rather than done yourself, a contingency firm is the right answer and we would rather tell you that than sell you a PDF you will not use.

Common questions
Is O'Connor & Associates legit?
Yes. O'Connor is a long-established Texas property tax firm with decades of appraisal review board and litigation experience, handling both residential and commercial property. It charges no upfront fee and bills only when it wins a reduction.
How much does O'Connor charge for a property tax protest?
About half of your first-year tax savings, with no upfront cost. Critically, that fee does not recur: you pay it in the year a reduction is won, not every year you keep it. On a $1,155 annual reduction that is roughly $578, one time.
Is O'Connor cheaper than Ownwell?
Over a multi-year hold, usually yes. O'Connor takes about 50% of first-year savings once. Ownwell takes 25% in Texas every year you keep the reduction. On a $1,155 saving that is about $578 total to O'Connor versus about $1,444 to Ownwell over five years.
Should I use O'Connor or file the protest myself?
If you will genuinely file and attend the hearing, a $49 flat-fee packet leaves you about $529 better off in year one on a typical reduction, and more each year after. If you will not show up to a hearing, a contingency firm that does the work is worth its cut, because a reduction someone else wins beats a packet you never file.
