Your parcel is scored against comparable sales, assessment history, and owner-level portfolio data to produce an over-assessment estimate and a modeled win probability.
Property tax appeals · Nationwide screening
Every other appeal firm waits for you to get angry at a notice and go shopping. We work the other direction: we screen nearly 122 million mapped parcels against comparable sales and assessment data, identify the over-assessed ones, and bring you a finished evidence packet before your filing window closes.
15% of first-year savings. No fee unless your assessment comes down.
Reactive. Deadline-driven. Priced for scarcity.
Proactive. Calendar-driven. Priced on our tech margin.
Your parcel is scored against comparable sales, assessment history, and owner-level portfolio data to produce an over-assessment estimate and a modeled win probability.
We generate a jurisdiction-specific evidence packet: the comparable set, the indicated value, the assessed value, and the dollar savings we intend to argue for.
You see the packet and the fee before anything is filed. If the case is weak, we tell you and we do not file. No retainer, no minimum, no signature to see the number.
We file as your authorized agent where the state allows it, and through a licensed local attorney, broker, or registered consultant where the state requires one.
Proof
Most firms in this category start with an office and hire analysts. We started with the data. Below is the actual state of the parcel layer behind RefundSnap, from an exhaustive county-by-county census of our production database on August 31, 2026 — every one of 3,243 county codes counted individually, not estimated. Of those codes, 1,820 counties carry real depth and hold 99.7% of the parcels below; the rest are thin boundary-spillover rows we count honestly but do not claim as county coverage.
Parcels mapped per state from the August 31, 2026 county census, after correcting 89 counties that had been attributed to a neighbouring state. All 51 jurisdictions are in the database; the ten deepest are shown here.
Mapping a parcel and being able to appeal it are two different things, so we report them separately. Assessed values are strongest in Florida (10.31M appeal-ready of 10.44M mapped), Texas (8.37M of 10.99M), North Carolina (5.59M of 5.86M), New York (4.63M of 5.91M) and Wisconsin (3.14M of 3.51M). They are effectively absent in Ohio (1,983 of 6.21M), Iowa (22 of 4.65M), Pennsylvania (26 of 4.08M), Virginia (74 of 3.82M) and Indiana (0 of 3.60M), and thin in California, where 1.39M of 8.10M mapped parcels carry a value. Those states are our active build queue. We would rather show you the gap than average it away.

Deadline and reassessment sources: California BOE rules for tax agents, appeal deadlines by state, protest deadline guide, Mass.gov real estate tax appeals, Texas TDLR property tax consultants, Tax Foundation reassessment provisions. National parcel universe for the coverage percentage: Regrid (160.8M assembled) and ReportAll (161.1M); LightBox puts nationwide coverage above 150M. Our own parcel, owner and value counts come from an exhaustive county-by-county census of our production database on August 31, 2026 — all 3,243 county codes counted individually. They are not estimates, and not third-party figures. We report parcel depth rather than a county headcount on purpose: 1,700 counties hold 5,000 or more parcels each and account for 121,460,511 of the total, while 1,412 county codes hold fewer than 100 parcels each — 2,867 rows combined, almost entirely parcels that straddle a county line and were published by the neighbouring assessor. Counting those codes as covered counties would overstate our footprint, so we do not.

For comparison, the national firms in this category typically charge 25–40% of savings. In states that require a licensed attorney, broker, or registered consultant to file, your engagement is with that licensed professional and the headline rate reflects their fee schedule.
Screening is nationwide from day one. Who signs the filing depends on state law, and we would rather say so up front than discover it at a deadline.

Non-attorney agent representation is permitted at the assessment-appeal level. We file as your authorized agent of record.

All remaining states
Your parcel is scored and monitored. If the case is strong, we either place it with a vetted local professional or hand you the evidence to file yourself.
Tell us where the property is. We will pull it from the screener, tell you whether the assessment looks high, and give you the filing deadline that applies to you. No cost, no obligation, no contract to see the number.
