About AppealDesk
AppealDesk is a property tax appeal evidence service. For a flat $49 fee, we generate a complete appeal packet for any residential property in the United States — comparable sales analysis, county-specific filing instructions, and a pre-written cover letter, delivered to your inbox in minutes.
The problem we solve is simple: according to the National Taxpayers Union Foundation, roughly 30-60% of all residential properties in the U.S. are overassessed. That means millions of homeowners are paying more in property taxes than they should be. Yet fewer than 5% ever file an appeal — not because the process is hard, but because most people don't know where to start or what evidence to bring.
AppealDesk closes that gap. We pull comparable sales data, verify assessment ratios against IAAO standards, and generate filing instructions specific to your county's appeal board. The entire process takes minutes, not days — and you keep 100% of your savings.
Who Built This
Rob Hartley — Founder
I'm a financial analyst with over 20 years of experience in data analysis and financial modeling, based in Nashville, Tennessee. My career has been spent turning raw numbers into actionable insights — skills that translate directly to property tax appeals, where the outcome depends on presenting the right comparable sales data in a way that's clear and defensible.
A few years ago, I found out my own home was overassessed by $87,000. I went through the appeal process, won, and saved over $1,800 a year — but the experience was frustrating. The data I needed was scattered across county websites, the forms were confusing, and it took me weeks of evenings to put together something I felt confident filing.
I kept thinking: this should take 15 minutes, not 15 hours. The comparable sales data exists. The filing rules are public. The cover letter is the same structure every time. So I built AppealDesk — a tool that does in minutes what took me weeks.
Every packet we generate uses the same approach I used for my own appeal: recent comparable sales within a tight radius, an assessment ratio check, and clear instructions for your specific county. No subscriptions, no percentage of savings, no upsells. Just $49 and the evidence you need.
How We Build Your Evidence
Every AppealDesk packet follows the same methodology that professional property tax consultants use — but at a fraction of the cost and delivered in minutes instead of weeks.
Comparable Sales Analysis
We source recent sales of similar homes near your property — matched by square footage, lot size, year built, and distance. These comps are the foundation of any successful appeal. County assessors rely on the same data; we just make sure the comps selected actually support your case.
Assessment Ratio Verification
Each state has its own assessment ratio — the percentage of market value used to calculate your assessed value. Ratios range from 4% in South Carolina to 100% in states like Texas and California. We verify your county's ratio against published standards and flag discrepancies that could be costing you money.
County-Specific Filing Instructions
Every county has its own appeal process, deadlines, and forms. We generate step-by-step instructions for your exact county — including the filing method (online, mail, or in person), required documents, and what to expect at each stage. We currently cover over 3,100 counties across all 50 states.
Pre-Written Cover Letter
Your packet includes a professional cover letter addressed to your county's assessment review board. It summarizes the comparable sales evidence, states the requested reduction, and uses the correct terminology for your state — whether that's "protest" in Texas, "grieve" in New York, or "appeal" in most other states.

Savings you keep
The average successful appeal saves homeowners over $1,000 per year, according to the Lincoln Institute of Land Policy. That savings compounds every year until the next reassessment — meaning a single successful appeal can save thousands over the life of your ownership.
What AppealDesk Is (and Isn't)
We believe in being upfront about what we offer. AppealDesk is a DIY evidence tool. We provide the data and documentation; you file the appeal yourself. Here's what that means in practice:
What we are
- ✓A property data analysis service
- ✓A source of comparable sales evidence
- ✓A filing instruction generator for 3,100+ counties
- ✓A flat-fee service — $49, no surprises
What we are not
- ✗Not a law firm or legal counsel
- ✗Not a certified appraisal
- ✗Not a full-service representation firm
- ✗Not a percentage-of-savings model
For most homeowners, the DIY approach is all you need. According to the IAAO, 97% of property tax appeals are resolved through informal review or by mail — no hearings, no courtrooms. You submit your evidence, the county reviews it, and you get a decision. If you want to understand the full range of options, see our comparison of appeal services.
