Why appeals work
Counties use mass appraisal — a formula applied to thousands of properties at once. Errors are inevitable. According to the National Taxpayers Union Foundation, 30–60% of residential properties are overassessed.
Your assessment is just an estimate. State law gives you the right to challenge it with evidence.
Most homeowners never check — they assume the county got it right. Research from the International Association of Assessing Officers shows fewer than 5% ever file an appeal. That's why overassessments persist year after year.
The fix is simple: show comparable sales that prove a lower value. If the data supports it, the county adjusts.

Three things that stop homeowners from filing
None of them should.
“What if my taxes go UP?”
They won't. In the vast majority of states, an appeal can only lower your assessment or leave it unchanged. The assessor reviews only what you challenge — they can't raise it as a result of your appeal.
“Will I have to go to a hearing?”
Almost certainly not. 97% of appeals are resolved by mail or informal review — no hearings, no courtrooms, no face-to-face confrontation. You submit your evidence, the county reviews it, and you get a decision.
“Is this actually worth $49?”
Tax consultants charge $300–$500 for the same analysis. Ownwell takes 25–35% of your savings every year. AppealDesk is a flat $49 — you keep 100% of every dollar saved. Even a modest reduction pays for itself 10× over.
Who Built This
Rob Hartley
Founder
After twenty years as a financial analyst, I'm used to spotting when numbers don't add up. My county assessed my home at $87,000 more than comparable sales in my neighborhood. I pulled the data, built the evidence, and won my appeal. $1,400 a year back in my pocket.
I built AppealDesk so you don't have to spend three weeks doing what I did. Comparable sales analysis, filing instructions, cover letter. Ready in minutes. $49.

Frequently asked questions
How does AppealDesk work?
You enter your property address, and we generate a complete appeal packet with comparable sales analysis, county-specific filing instructions, and a pre-written cover letter. Everything is delivered to your email within minutes.
What if my property isn't overassessed?
We'll tell you. If our analysis shows you're assessed at or below market value, we'll explain why and recommend against filing. You still receive the full analysis so you understand your property's position.
What if I lose my appeal?
Nothing happens. Your assessment stays the same. There's no penalty for filing, and your taxes cannot be raised as a result of your appeal. The only risk is the time it takes to file.
Do I need a lawyer or consultant?
No. Property tax appeals are designed for homeowners to file themselves. Your packet includes step-by-step instructions written for your specific county. Most appeals are resolved without a formal hearing.
How much can I save?
It varies by property and county. National data shows successful appellants save between $539 and $1,346 per year on average. Some save significantly more, especially on higher-value properties.
Do you take a percentage of my savings?
No. You pay $49 once and keep 100% of any tax reduction you receive. We never take a cut of your savings, and there are no recurring fees.
This is the year you stop overpaying.
Every year you don't appeal, you lock in an inflated baseline. The cost of waiting isn't $0 — it's every dollar you've already overpaid.
