Real comparable sales, an honest verdict, and a board-ready letter — you keep 100% of what you save. The only appeal tool that tells you when NOT to file.
Your property tax bill might be too high — and most homeowners never check.
Launching in Pennsylvania first — fully tuned to PA's Common Level Ratios and county appeal boards, with more states on the way. (You can explore the app anywhere; paid analysis runs only in fully supported states.)
Assessments are often wrong, but few owners ever challenge them. PROppeal's evidence engine helps you find out if your home is over-assessed and build a strong, board-ready appeal — and you keep 100% of what you save. No contingency fees. No subscription.
LOWER YOUR PROPERTY TAXES
If your home is assessed for more than it's worth, you're overpaying every year — and it doesn't correct itself. PROppeal builds your case the way the pros do: real comparable sales, size adjustments with the math shown, and a board-ready appeal letter with the evidence table your county expects.
A REAL EVALUATION ENGINE — NOT A GUESS
At the core of PROppeal is an evidence engine that does the work: it pulls recent comparable sales near your home from licensed property data, adjusts each one to your home's size, and gives you an honest read on whether the evidence supports a lower value. If it doesn't, PROppeal tells you — so you never waste a filing on a weak case.
HOW IT WORKS
1. Add your home. Enter your address and the assessed value from your notice — PROppeal pulls your property's details and county rules from there.
2. Find real comps. The evidence engine pulls recent comparable sales near your home — actual sold prices, not online estimates.
3. See your case honestly. It adjusts the comps to your home's size and tells you whether they support a lower value — even when they don't.
4. Generate your letter. A professional, board-ready appeal letter built on your evidence, with a comparable-sales table and a size-adjusted value.
5. File and track it. Export the PDF, file with your county, and log how it turns out.
WHY PROppeal
- Real comparable sales, not guesses. Built on licensed property data and recent sold prices — the evidence review boards actually weigh.
- Size-adjusted, like an appraiser. Each comp is normalized to your home's square footage, with the math shown — not hand-waved.
- An honest case check. If the evidence doesn't support an appeal, the engine says so, so you don't waste a filing.
- Keep 100% of your savings. Appeal companies take a cut of your first-year savings. PROppeal is a simple one-time credit per appeal — no subscription, no contingency fee.
- Track your outcome. Log whether your appeal won and what you saved, and pick up next year right where you left off.
A SMARTER WAY TO CHALLENGE AN UNFAIR ASSESSMENT
Property taxes are one of the largest ongoing costs of owning a home, and assessments are frequently too high. PROppeal puts real data and an honest evidence engine in your pocket — so you can lower your bill, keep your money, and do it with confidence.
Lower your property taxes. Keep what you save. An honest read on your case, either way.
