What actually wins a commercial property tax appeal

The bar you have to clear

In In re Appeal of AMP, Inc. (1975) the Supreme Court of North Carolina set the test still used today. Assessments are presumed correct. To rebut that, the owner needs competent, material and substantial evidence that the county used an arbitrary or an illegal method of valuation, and that the assessment substantially exceeded true value. Ten years later, in Southern Railway, the Court added the other half: once the owner does that, the county has to show its own method produces true value.

The Board is not asking whether the tax is fair. It is asking what the property would sell for.

Evidence that moves a Board

The income the property actually earns

Buyers of income property pay for income. A county mass appraisal applies market rents, vacancy and expense ratios across a class of property. Your rent roll and operating statements show what this building earns, and where it differs from the county’s assumptions, that is usually the case.

Sales that are genuinely comparable

Arm’s-length sales of similar property near the revaluation date. Not foreclosures, not sales between related parties, not a portfolio deal with one building’s price backed out by guesswork.

What the county does not know

Deferred maintenance, a roof at the end of its life, functional problems with the layout, environmental issues, a tenant on a below-market lease that runs for years. Mass appraisal rarely sees any of it.

Someone who can explain it

A Board hears a lot of owners who are unhappy with their bill. It listens differently to a credentialed appraiser walking through sales, income and adjustments the way the county’s own staff would.
