Property Tax Appeal Companies vs DIY: When to Hire Help and When to Do It Yourself
TL;DR
DIY property tax appeals are free but have lower success rates because most homeowners don't know what evidence to gather. Full-service companies like Ownwell handle everything but take 25% of savings. The sweet spot is a flat-fee evidence tool like TaxFightBack ($79) that gives you professional evidence and county-specific instructions so you can file yourself with confidence. You get the DIY savings with professional-grade preparation.
The Three Options for Appealing Property Taxes
When your property tax assessment comes in too high, you have three basic paths:
- Full DIY. Research comps yourself, build your own case, file and attend hearings solo. Cost: $0.
- Full-service company. Pay someone to do everything. Cost: 25% of savings or $500+.
- Evidence tool (assisted DIY). Get professional evidence and instructions, file it yourself. Cost: $79.
Each approach has trade-offs. The right choice depends on your confidence level, your time, and how much you expect to save.
Full DIY: Free but Risky
What You Do
You research your own comparable sales, figure out your county's appeal process, fill out the forms, gather evidence, and present your case at a hearing.
What Goes Wrong
Most homeowners who go fully DIY run into the same problems:
- Bad comps. They pick homes that aren't truly comparable, are too far away, or sold too long ago. The review board dismisses them.
- Missing evidence. They show up with a Zillow estimate instead of actual sales data. That's not evidence.
- Wrong process. They miss deadlines, file the wrong form, or don't follow their county's specific procedure.
- Weak presentation. They argue emotionally ("my taxes are too high") instead of presenting data ("these five comparable homes sold for less than my assessed value").
Success Rate
DIY appeals without professional evidence succeed roughly 30-40% of the time. Compare that to 50-60% for the overall average (which includes professionally assisted appeals) and 70-80% for well-prepared cases with strong comparable data.
When DIY Makes Sense
- You have real estate experience and know how to pull comps
- Your assessment has an obvious error (wrong square footage, extra bedroom listed)
- You've done this before and know your county's process
- The potential savings are small (under $300) and don't justify any fee
Full-Service Companies: Convenient but Costly
What They Do
Companies like Ownwell and TaxProper handle everything. They evaluate your property, build the case, file the appeal, attend hearings, and negotiate with assessors. You sign up and wait for results.
What It Costs
Most charge a contingency fee of 25% of your first-year savings. On a $2,000 savings, that's $500. NTPTS charges $500+ upfront regardless of outcome.
| Your Savings | Full-Service Cost (25%) | You Keep |
|---|---|---|
| $800 | $200 | $600 |
| $1,500 | $375 | $1,125 |
| $2,500 | $625 | $1,875 |
| $4,000 | $1,000 | $3,000 |
When Full-Service Makes Sense
- You have zero time to deal with any paperwork
- You're in a covered area (most only serve select states)
- You're willing to trade savings for convenience
- Your property has a complex situation requiring expert negotiation
Flat-Fee Evidence Tools: The Middle Ground
What They Do
Services like TaxFightBack sit between DIY and full-service. For $79, you get a professional evidence packet with AI-selected comparable sales, market analysis, and county-specific filing instructions. You file the appeal yourself, but you're armed with the same quality of evidence that full-service companies use.
What It Costs
$79 once. That's it. Your savings are your savings.
| Your Savings | TaxFightBack Cost | You Keep |
|---|---|---|
| $800 | $79 | $721 |
| $1,500 | $79 | $1,421 |
| $2,500 | $79 | $2,421 |
| $4,000 | $79 | $3,921 |
Why This Works
The hard part of a property tax appeal isn't the filing. It's the evidence. Finding the right comparable sales, analyzing them correctly, and presenting them in a format the review board expects. That's what most homeowners get wrong when going fully DIY.
A flat-fee evidence tool solves the hard part. It gives you professionally formatted comps, market data, and clear instructions. The easy part, filling out a form and submitting it, is what you handle yourself.
Think of it like doing your own taxes with TurboTax instead of hiring a CPA. The software does the hard work. You press submit.
When Flat-Fee Evidence Makes Sense
- You want professional evidence without the professional price tag
- You're comfortable spending 1-2 hours on filing
- You want to keep 100% of your savings
- You live anywhere in the US (3,100+ county coverage)
- You want to understand your own assessment and appeal
Side-by-Side Comparison

|---|---|---|---|
| Cost | $0 | $79 | 25% of savings |
| Evidence quality | Varies widely | Professional-grade | Professional-grade |

The Real Question: Is Your Time Worth $421?
The difference between TaxFightBack ($79) and a full-service company (25% on $2,000 = $500) is $421. The extra work on your end is about 1-2 hours of filing.
That means you're effectively paying yourself $210 to $421 per hour by filing the appeal yourself with TaxFightBack's evidence. For most people, that's a pretty good hourly rate.
The difference between full DIY ($0) and TaxFightBack ($79) is $79. But the jump in success rate from 30-40% (DIY) to 50-70% (with professional evidence) makes that $79 one of the best investments you can make. On an expected savings of $1,500, the expected value of professional evidence more than pays for itself.
The Verdict
For most homeowners, the flat-fee evidence model hits the sweet spot. You get the evidence quality of a full-service company at a fraction of the cost, and you keep all your savings. The filing process itself is straightforward. It's the evidence preparation that matters, and that's exactly what TaxFightBack handles for $79.
