How it works | Fair Check Utah

Five steps

Your county record

Assessed value, size, year built, straight from the county.

Real sales

Actual closed prices of homes like yours. Utah keeps them off the public record; we have them.

The comparison

Our tested value model puts the county's number against the sales. Bought recently? Your price counts first.

Your verdict

A straight answer either way. We never sell an appeal we do not believe in.

If you qualify

File it yourself with our evidence, or we build, file, and track the whole appeal for you.

One fix, five years of savings

If an appeal saves you

$250 per year

$1,250

estimated over the next five years

The fix sticks. Next year's value builds on this year's. Correct it once, and Utah law puts the burden of proof on the assessor to raise it again.

One flat fee. No percentage of your savings. No subscription.

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…

Why most people never appeal

The county will never call to tell you it guessed high.

Fair questions

What does the check cost?: Nothing, whichever way it comes out.
Is this legal?: Yes. Utah law allows representative filing and sales-evidence estimates (Utah Code 59-2-1017).
I just bought my home. Worth checking?: Especially then. Your own price is the strongest evidence a county accepts.
Does a lower assessment hurt me when I sell?: No. Buyers use market comps, not the tax value.
Who actually files?: You, with our worksheet. Or us, as your authorized representative: one signature, no notary.
What evidence do counties accept?: 3 to 5 comparable sales, your own purchase, or an appraisal. We push for five comps when five exist.
What if my home is newly built?: Finished-home sales cannot argue against a construction-state value. Your closing documents can.
How do you know the model is right?: We test it blind against real sales, county by county, and refuse neighborhoods where it cannot prove itself.
Will I have to go to a hearing?: Almost never. Most appeals settle on the written evidence.
Is my information safe?: Never sold. Unsubscribe any time.
