Every few years in Guilford County, like clockwork, the reassessment notices go out — and a lot of property owners have the same reaction: There’s no way my property is worth that.

What follows is a quiet but very real surge in activity that most people don’t see – appeals filed, evidence gathered, hearings scheduled, and homeowners and business owners trying to make their case that the county got it wrong.

And here’s the thing: sometimes they do.

The good news is that a property tax appeal in North Carolina isn’t some mysterious insider process reserved for attorneys and appraisers. Regular people win some of these appeals every year. However, they don’t win by complaining about taxes being too high. They win by showing that the value is wrong.

There’s a difference — and it’s everything.

In North Carolina, including Guilford County, the process starts with an informal review through the county’s tax office.

If that doesn’t resolve it, the appeal can go to the county’s Board of Equalization and Review, and beyond that to the state’s Property Tax Commission in Raleigh.

At every stage of the process, the burden is on the property owner to show that the county’s number isn’t supported by the facts.

There are three ways people tend to win.

The first is by knocking out a bad sale that the county relied on. Sometimes assessors use a recent sale to support a value –  however, not all sales are created equal. If the property was transferred between family members, sold under pressure in a foreclosure or short sale, bundled into a larger deal, or included personal property like furniture or equipment, then it might not reflect true market value. If you can show that the sale wasn’t arm’s length, you’ve taken away one of the county’s key supports.

The second is proving that the condition of the property is worse than the county is assuming. Mass appraisal system participants don’t walk through your house. They don’t see the roof that needs replacing, the HVAC system on its last leg, or the water damage in the crawlspace. But a buyer would – and a buyer would lower their offer accordingly. That’s where photos, contractor estimates, and inspection reports come in. Vague claims that a property “needs work” don’t carry much weight. But documentation does.

The third is identifying errors in the county’s own records or valuation model. Sometimes the county has the wrong square footage, lists finished space that isn’t actually finished, assigns the wrong effective age or applies land values that don’t match the neighborhood. These aren’t dramatic mistakes  –  but they can add up. And once you start pointing them out, the valuation can begin to look less reliable.

What matters in all of this is hard evidence: Dated photos. Written contractor estimates. Comparable sales that actually resemble the property in question — not cherry-picked high-end examples, but realistic comps that reflect similar condition and use. Copies of deeds and settlement statements. Screenshots of the county property card with errors highlighted.

This isn’t about bringing a stack of paper and hoping something sticks. It’s about building a clear, simple case that the number on the notice doesn’t line up with reality.

It also helps to keep expectations in check. The goal isn’t to prove a perfect value down to the dollar. The goal is to show that the county’s number is off enough that it shouldn’t stand.

And it’s important to stay focused on that. Arguing that taxes are too high won’t get very far. The Board of Equalization and Review isn’t there to set tax rates – it’s there only to determine value. If the value goes down, the tax bill follows. If it doesn’t, the rate discussion is happening somewhere else entirely.

There are also some common pitfalls. Relying on Zillow instead of actual sales data. Bringing too many comps instead of a few strong ones. Making broad claims without documentation. Or simply missing the deadline to file an appeal, which ends the conversation before it starts.

For Guilford County property owners, the first step is straightforward.  Pull up your property record, look at what the county says about your home or business, and start checking it against reality. If something doesn’t match, that’s where the process begins.

Listen,  the county’s revaluation system isn’t perfect – and it’s not really designed to be. It’s a mass appraisal process trying to value thousands of properties all at once. That works reasonably well overall, but it inevitably produces outliers and the onus is on the property owner to let the Tax Department know if they got it wrong.
