Property tax appeal
Ownwell
Ownwell manages property tax appeals end to end, pairing local property tax consultants with its own software to build the evidence behind each protest. It serves homeowners, single-family rental investors, commercial owners and enterprise portfolios, and also takes referrals from real estate agents, mortgage servicers, property managers and lenders.
Signing up starts with an address and the Ownwell service and authorization agreements, after which the company verifies ownership and begins the appeal. Owners complete an annual property survey and can upload photos, repair estimates or comparable sales through a property portal; Ownwell files the paperwork, deals with county assessors and attends appeal board hearings. A separate tax bill service finds bills, forecasts what is owed, secures early payment discounts, monitors for delinquency and consolidates payment.
Ownwell lists appeal coverage in California, Colorado, Florida, Georgia, Illinois, New York, Pennsylvania, Texas and Washington. It reports that 88% of customers received a reduction on at least one appeal in 2025 and that customers who saved averaged $774 that year, and shows a 4.7 rating from more than 3,000 Google reviews. The tax bill management service says it is used by more than 10,000 businesses.
There is no charge until a reduction is confirmed, but the contingency rate varies by region, so check the published rate for your county before signing. Exemptions already on the property reduce the final fee, and the invoice is issued only once the taxing authority has documented the reduction.

Common questions
- How much does Ownwell charge?
- Nothing up front. Ownwell charges a contingency fee only after it reduces a property tax bill, and if there is no saving the service is free. The fee applies to the actual savings in the year appealed: at a 25% fee on a bill cut from $5,000 to $4,000, the invoice is $250. Rates are published by region.
- Why might my property assessment be too high?
- Ownwell lists the common causes as mass appraisals by counties, inaccurate comparable sales, market movements that the appraised value no longer reflects, exemptions the owner qualifies for but has not claimed, and unbuilt or unfinished improvements counted as complete.
- What happens after I sign up?
- Ownwell verifies that you own the property and begins work on the appeal. Updates on the property and the appeal status come by email, and evidence such as photos, repair estimates or comparable sales can be uploaded through your property portal at any time.
- Is appealing a property assessment legal and common?
- Yes. Ownwell states that nearly all US states and local governments allow property tax appeals, and that ensuring a property is fairly taxed is the owner's right.
- How do exemptions affect the fee?
- The contingency fee applies to actual property tax savings in the year appealed. Where a homestead, over-65 or other exemption is active, Ownwell adjusts the final fee by the discounted amount, and bills only once the taxing authority has issued a signed document proving the bill was reduced.
