How it works | Fair Check Utah

The process, step by step

Your county record

We pull your home's official record from the county: the 2026 assessed value, square footage, year built, lot size. Straight from the source, seconds after you apply.

Real sales, not estimates

We pull actual closed sales of comparable homes around yours. Utah is a non-disclosure state: sale prices are not public record, which is why homeowners, and most national appeal services, cannot build this case. Access to real sale prices is the entire game.

The honest comparison

A valuation model we test against real sales, county by county, compares your assessment to the evidence. We publish our own error rates to ourselves and refuse to screen in neighborhoods where the model cannot prove itself. If you bought recently, your own purchase price gets checked first: the county's rules accept it as the strongest evidence there is.

Your verdict, either way

About one home in seven has a real case. If yours does, you see your estimated five-year savings and your options for acting on it. If it does not, we say so plainly and show you the value range that proves the county right. We never sell an appeal we do not believe in.

If you qualify and want us to handle it

We build the evidence packet, write the argument in the county's own review terms, recommend the number to ask for, show you everything for approval, file before September 15 as your authorized representative (one signature from you, no notary), and track it to the county's final decision. Flat fee, shown with your results. If the county gives you no reduction at all, the full-service fee comes back in full.

One correction, five years of savings

Property tax mistakes compound. The county builds next year's value on top of this year's, so a high number left alone keeps costing you. Fixing it once resets the base.

If an appeal saves you

$250 per year

$1,250

estimated over the next five years

Why the fix sticks. Utah law has a name for a home that wins its appeal: qualified real property. If the county wants to raise a corrected value beyond normal market growth without physical changes to your home, the burden of proof is on the assessor, not on you.

So this is a one-time fix with a five-year tail. That is why we charge one flat fee instead of taking a percentage of your savings, and why there is no subscription.

What the work looks like

Two fragments from a sample case file. Yours is built from your home's county record and the actual recent sales around you.

From the written argument (full service)

Why the assessment overstates the value

The county's 2026 value works out to $225 per square foot. Four sales of comparable homes in the same subdivision closed between September 2025 and January 2026 at $195 to $204 per square foot, each within a quarter mile of the subject and within 10 percent of its size. Applied to this home's county-recorded 2,405 square feet, the sales evidence supports a value of…

Built to answer fast

The check runs on county records and recent sale data, start to finish, and you watch it happen live on your results page. Most checks come back the same day, many within minutes.

Pulling your county record

Assessed value, square footage, lot, year built, straight from the county.

Pulling recent sales around you

Actual closed prices of comparable homes, the evidence Utah counties ask for.

Running the numbers

The same value model we test against real sales, county by county.

Your answer

You qualify with an estimated savings band, or the number is fair and we show you why.

The guarantee, in plain words

It lives on the full-service option, because that is where we control the work.

If we file for you and the county's final decision gives you no reduction at all, our fee comes back in full. A partial reduction counts as a win, because it saves you money every year from now on.

We verify every outcome against the county's own record, and we send you the result either way, with the math on what you are saving.

The longer answers

Who actually files the appeal?: Either you (with our evidence in hand and a worksheet showing exactly where to write what), or us, as your authorized representative. Utah counties explicitly support representative filing: you sign one authorization, no notary, and everything else including the county's questions comes to us.
What evidence do counties accept?: Their own published standards: 3 to 5 comparable sales close to the January 1 valuation date, a recent purchase of the property itself, or a professional appraisal. We build the comparable-sales case, push for five comps when five defensible ones exist, and use your own purchase when you have one, because it is the strongest evidence of all.
What if my home is newly built?: New construction is valued as of its January 1 construction state, which finished-home sales cannot argue against. If you bought or built for less than the county's value, your closing documents can, and we will tell you exactly that in your results.
How do you know your model is right?: We test it the hard way: hide the sale price of homes that really sold, predict them blind, and score the miss. Where it cannot prove itself within our error standard, we refuse to use it and rely on purchase evidence instead. That discipline is why our verdicts are honest in both directions.
What happens after filing?: The county assessor reviews the evidence and mails a recommendation, usually within several weeks. Most appeals settle right there. Declining a recommendation leads to a short informal hearing; if one is ever needed, everything gets prepared and you will know exactly what to expect. Final decisions land by late fall, in time for the November bill.
Is my information safe?: We only email you about your own home unless you opt into updates, we never sell your information, and the check itself uses public county records plus licensed real estate data.
