What the next 30 minutes look like
From order to filed appeal, most homeowners finish the same day.
Your packet arrives by email
Within minutes of ordering, you get an email with your complete appeal packet attached as PDFs. No login, no portal, it's in your inbox.
Open the Evidence Packet
You see 10–20 comparable sales, real homes similar to yours that sold for less than your assessed value. Each comp shows the sale price, square footage, distance from your property, and why it supports a lower assessment.
Open the Filing Guide
Your county's exact deadline, the form you need, where to submit, and every step in order. No Googling, no guessing which office to call.
Sign the Cover Letter and submit
Your appeal letter is already written and addressed to your county. Print it, sign it, attach your evidence packet, and submit. Most counties accept mail, email, or online upload.
Done. Your appeal is filed.
The county reviews your evidence and mails you a decision, typically 4–8 weeks. If the data supports it, your assessment drops and your tax bill follows. That lower bill repeats every year until the next reassessment.

What ChatGPT Recommends
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.
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.
- They assume your 1,850 sq ft home is 2,200 sq ft because the record says so
- They value your 25-year-old roof like it is new
- They use sales from the newer section with the golf course
- They count a converted garage as a true fourth bedroom
- They ignore the busy road, drainage issue, or condition problem affecting your value
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.

Who Built This
Travis Bunn
Founder
I've spent 15 years in real estate, with a quantitative trading background before that. I've owned homes in multiple states and appealed the property taxes on every one of them, successfully. The evidence that wins is always the same: what homes like yours actually sold for, presented clearly.
AppealDesk is the system I built for my own appeals. Comparable sales analysis, filing instructions, cover letter. Ready in minutes. $49.

Frequently asked questions
What do I actually get?
A complete appeal packet: comparable sales analysis, county-specific filing instructions, and a pre-written cover letter. Just enter your property address and 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.
What we will not pretend
We cannot change your tax rate. We cannot reduce taxes if your assessment is already fair. We cannot guarantee every appeal wins.
What we can do is help you find out whether your county's number holds up under scrutiny.
That is valuable either way. If your assessment is fair, you get clarity. If it is inflated, you may have a real opportunity to reduce a bill that keeps coming back every year.
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.
If your home is fairly assessed, we'll tell you, and you still receive your full Property Tax Analysis with exemption opportunities. $49 always gets you something.
