AppealKit vs Ownwell

If you think your home is assessed for more than it's worth, you have two very different ways to do something about it. You can hand the whole thing to a company that files, negotiates, and shows up to the hearing for you — and takes a cut of whatever they save you. Or you can build a hearing-ready appeal yourself with a tool that charges one flat fee and lets you keep every dollar of the result.

AppealKit is the second kind. Ownwell is the first. This page lays out the honest trade-offs so you can pick the one that actually fits your situation — including the cases where a done-for-you service is the better call.

Bottom line: For a homeowner who's willing to spend a little effort and wants to keep every dollar of their savings, AppealKit is the strong default. You pay one flat fee, you keep 100% of the reduction, and you walk into your hearing with the per-comparable adjustment grid that boards actually reward — instead of handing a recurring percentage of your savings to a service year after year. If you'd rather the whole thing be off your plate and don't mind paying a cut for that convenience, Ownwell is a fair fit. But for the mainstream homeowner who can put in a few hours, the flat-fee, keep-it-all route is the one we'd point you to.

A quick note before we start: AppealKit is a tool, not your representative, and nothing here is legal or tax advice. We'll also be careful to label what we know about Ownwell as what their site said when we last reviewed it — pricing and policies change, so verify anything that matters to you on their site directly.

What's the core difference between AppealKit and Ownwell?

It comes down to who does the work and how you pay for it.

Ownwell is a done-for-you service. As of 2026-06-24 (per Ownwell's site), you give them your address, answer some questions, and their team handles the end-to-end process: filing the paperwork, building the evidence, negotiating with the county assessor, and attending appeal hearings on your behalf. You don't prepare a presentation or learn your local board's rules. In exchange, they charge a contingency fee — a percentage of your first-year tax savings — with no upfront cost. If they don't reduce your bill, their site says you pay nothing.

AppealKit is a flat-fee, self-service tool. You build the appeal yourself, but you're not starting from a blank page. AppealKit produces a hearing-ready packet — a per-comparable adjustment grid plus the official application your county uses — so you walk in with the same kind of evidence an assessment appeals board expects to see. You pay one flat fee, and you keep 100% of whatever you save. There's no percentage taken off the top.

That's the whole fork in the road: pay a percentage of your savings to have someone else do it, or pay a flat fee and do it yourself with the evidence built for you.

How does the cost actually compare?

This is where the two models diverge the most, and the math is worth doing slowly.

A contingency fee scales with your savings. As of 2026-06-24 (per Ownwell's site), their worked example uses a 25% fee: if your tax bill drops by $1,000, the fee on that reduction is $250. The bigger your reduction, the bigger the fee — and on a high-value home with a large over-assessment, exactly the case where an appeal is most worth doing, the percentage can add up.

Here's a fair illustration with round numbers (an example, not a quote for either company): say your appeal lands a $2,000 reduction in your annual tax bill. Under a 25% contingency fee, that's roughly $500 taken off your savings — leaving you $1,500. With AppealKit's flat fee, you keep the full $2,000. And the contingency math doesn't necessarily stop after one year: if a service re-files and protects that lower value in future years, the percentage cut can recur, so a single $2,000 win could mean ~$500 again next time. A one-time flat fee doesn't.

A flat fee doesn't scale with your savings. With AppealKit you pay the same flat fee whether your appeal saves you $400 or $4,000, and the savings are entirely yours to keep — this year and the next.

The honest counterpoint: if your reduction turns out to be small or uncertain, a contingency service's "only pay if you save" structure caps your downside — a small fee on a small saving, and nothing at all if the appeal fails. For a borderline case where you're not sure there's much to win, no-win-no-fee can genuinely be the safer bet. And a free check costs you nothing either way. Which brings us to the real question.

Who actually does the work — and do you want to?

With Ownwell, the answer is "they do," and for a lot of people that's the entire appeal of a service like theirs. Per their site (as of 2026-06-24), they handle filing, evidence, negotiation, and hearing attendance — and their materials describe a DIY appeal as taking several hours to well over a dozen, which is a fair description of doing it cold, with no tools.

AppealKit's answer is "you do, but most of the hard part is built for you." The genuinely hard part of a residential appeal isn't the filing — it's the evidence. The most common reason a homeowner's appeal gets dismissed is using raw, unadjusted comparable sales: a list of houses that sold nearby without accounting for the differences between them and yours. Assessment boards expect adjusted comparables.

That's exactly what AppealKit builds: a per-comparable adjustment grid that adjusts each comp up or down for square footage, bedrooms and baths, lot size, condition, and the other real differences, so you're comparing like with like. This is the same comparable-sales method assessors and appeals boards use, and California's State Board of Equalization specifically endorses the adjusted-comparable approach for residential appeals (BOE Publication 30, Residential Property Assessment Appeals). So while you're the one who files and, if it goes that far, speaks at the hearing, you're doing it with the kind of evidence that gets taken seriously — not winging it.

The real question isn't "can I do this?" It's "do I want to be involved, or do I want it off my plate entirely?"

What do you actually get from each?

Ownwell gives you a hands-off outcome: per their site, a team that runs a market analysis, files, negotiates, and attends hearings, plus adjacent services like exemptions filing, insurance shopping, and bill reduction. The deliverable is the result, not a document you control.

AppealKit gives you the artifacts: a free check that tells you — with no account and no email — whether you actually look over-assessed, and then a complete appeal kit (the adjustment grid plus the official application) that's yours to file. The deliverable is the evidence and the paperwork, and you keep all of it.

What about coverage?

This is a real point in Ownwell's favor today. As of 2026-06-24 (per Ownwell's site), they operate across a number of states — including Texas, California, New York, Florida, Georgia, Washington, Colorado, and Illinois — for both residential and commercial properties. If you own properties in several states, a single service spanning all of them is genuinely convenient.

AppealKit is focused on do-it-yourself residential appeals and is rolling out market by market (starting with San Francisco). If your county isn't covered yet, a national service may reach you and a DIY tool may not — that's an honest limitation, not a footnote.

One coverage nuance worth knowing regardless of which route you choose: in most states, filing an appeal can't raise your assessment, but per Ownwell's own site, Georgia and Washington are exceptions where a contested value can be reassessed upward. If you're in one of those states, that risk exists no matter who files — understand it before you start. (Confirm the rules for your specific county; this isn't legal advice.)

Who should choose AppealKit vs Ownwell?

Choose AppealKit if you're the mainstream homeowner with a single residence who can put in a few hours and wants to keep all of your savings:

• You want to keep 100% of your reduction and pay one predictable flat fee instead of a recurring cut of your savings.
• Your potential reduction is large enough that a percentage fee — possibly year after year — would sting.
• You're willing to file and, if needed, speak for a few minutes at a hearing — especially once the hard evidence is built for you as a board-ready adjustment grid.
• You want to find out whether you even have a case before spending a dollar or handing over your property and contact information.

For most homeowners with one home and a few hours to spare, this is the better deal: you do the visible-but-manageable part, and you keep what you save.

Choose a done-for-you service like Ownwell if you'd rather not touch it at all:

• You want the whole thing off your plate and are comfortable paying a percentage of your savings for that convenience.
• You own multiple properties, or properties across several states, and want one relationship covering all of them.
• The idea of presenting evidence at a hearing is a dealbreaker for you.
• Your reduction is small or uncertain and you'd rather pay nothing unless it works.
• Your county isn't somewhere a DIY tool currently operates.

There's no universally right answer, and the contingency model exists for good reason — plenty of homeowners happily trade a slice of their savings for never thinking about it. But if you're willing to do a little, the flat-fee DIY route keeps the whole reduction in your pocket and your data in your hands. Either way, start with the free check: it costs nothing, needs no account or email, and tells you whether an appeal is even worth your time before you commit to anything.

FAQ

Is AppealKit cheaper than Ownwell? It depends on your savings. AppealKit charges one flat fee and you keep 100% of your reduction. Per Ownwell's site (as of 2026-06-24), they charge a contingency fee — a percentage of your savings, with no upfront cost. The larger your reduction, the more a flat fee favors you; on a small or uncertain reduction, a contingency fee caps your downside. Run the free check to estimate your potential savings first.

Does AppealKit file the appeal and go to the hearing for me? No. AppealKit is a tool, not your representative. It builds a hearing-ready packet — an adjustment grid plus the official application — that you file yourself. A done-for-you service like Ownwell handles filing and hearing attendance on your behalf, per their site. If hands-off is what you want, that's the trade-off you're paying the contingency fee for.

Do I need a lawyer for either option? For most residential appeals, no. See our guide on whether you need a lawyer to appeal property tax. The comparable-sales evidence that wins residential appeals is something you can prepare yourself, and AppealKit builds it for you.

Will appealing raise my property taxes? In most states an appeal can't increase your assessment. Per Ownwell's own site, Georgia and Washington are exceptions where a contested value can be reassessed upward. Confirm the rules for your county before filing. This isn't legal advice. Our explainer on what an over-assessment is covers the basics.

What do AppealKit's comparable-sales adjustments actually do? They adjust each nearby sale up or down for the differences between that home and yours — size, beds and baths, lot, condition, age — so you're comparing like with like. Unadjusted comps are a common reason appeals get dismissed. Learn more in our comparable sales glossary entry and our guide to appealing property tax.
