If you’re searching for:

- “Ownwell vs O’Connor”
- “property tax protest cost”
this article will provide you with the data and insights to help you decide. Let’s look at actual Harris County protest data and break it down objectively.
2025 Protest Volume & Success Rates (All Property Types)
| Company | 2025 Protests | 2025 Reductions | 2025 Success % |
|---|---|---|---|
| O’CONNOR & ASSOCIATES | 74,394 | 65,549 | 88% |
| OWNWELL INC | 67,397 | 61,430 | 91% |
| BETTENCOURT TAX ADVISORS | 17,981 | 15,474 | 86% |
| RAINBOLT & COMPANY | 12,804 | 11,622 | 91% |
| RESOLUTE PROPERTY TAX | 11,790 | 10,130 | 86% |
| ADVALOREMTAX.NET | 11,619 | 9,750 | 84% |
| NOVOTNY AND COMPANY | 10,011 | 8,740 | 87% |
| TEXAS TAX PROTEST | 7,642 | 6,371 | 83% |
| ELLIOTT-WELLMAN | 6,762 | 6,157 | 91% |
| RYAN LLC | 6,025 | 5,491 | 91% |
| HARDING & CARBONE | 5,256 | 4,559 | 87% |
| AD VALOREM ADVISORS | 5,064 | 4,733 | 93% |
These firms handle tens of thousands of protests every year. High success rates look impressive. A success rate only tells you that some reduction occurred, not how large it was. But here’s the critical point:
Success Rate Is Not a Guarantee of Maximum Reduction
A 90% success rate simply means a reduction occurred in 9 out for 10 protests. It does not tell you:
- Whether the reduction was the maximum possible
- Whether unequal appraisal was fully analyzed
- Whether the homeowner’s specific condition issues were argued
- Whether you could have achieved the same (or better) result yourself
A small reduction counts as a “win”.
What Long‑Term Data Shows About DIY
From the broader Harris County dataset (2017–2025), DIY homeowners consistently achieve:
- Comparable or higher median reductions than agent-represented properties
- Strong success rates when properly prepared
For example:
| Year | DIY Median | Agent Median |
|---|---|---|
| 2024 | $21,733 | $13,060 |
| 2025 | $20,640 | $13,202 |
Over multiple years, DIY median reductions have exceeded agent medians. That means many homeowners who represent themselves walk away with equal—or better—reductions.
Fees Change the Equation
Most property tax protest companies charge:
- 25%–50% of tax savings (contingency)
Even if an agent gets a solid reduction, you give up a large portion of it. DIY keeps 100% of the savings. Higher net savings > higher gross savings.
Quick Comparison: Hire vs DIY
| Factor | Hire Company | DIY |
|---|---|---|
| Upfront cost | Usually $0 | Small flat fee (tools/reports) |
| Fee after win | 25–50% of savings | $0 |
| Control | Low–medium | High |
| Best for | Complex/commercial cases | Most single-family homes |
| Net savings | Reduced by % fees | Keep 100% |
Bottom Line
Professional protest companies can be helpful — especially for commercial or complex properties. But for most single-family homeowners:
- Success rates alone don’t tell the full story.
- Median DIY reductions have historically matched or exceeded agent results.
- DIY means you keep everything you save.
Protest, but protest smart.
