According to Durham County's property value appeal guidance, when you buy a house in Durham County, the property tax bill doesn't follow your purchase price. It follows an appraisal the county finished for January 1, 2025. Between reappraisals, North Carolina doesn't allow the county to raise or lower a parcel's tax value except in a few cases, such as a zoning change or a change to the property itself, like adding or removing a structure. Durham's next reappraisal takes effect January 1, 2029.
So whoever buys this fall takes on a number set nearly two years ago, and it will stay in place for more than two more. That number got a lot of attention in 2025. It drew a record wave of appeals, and the results were uneven in ways that matter to anyone pricing a single-family home today.
A record jump, then a record pushback
The 2025 revaluation was Durham's first since 2019. The News & Observer reported average assessed-value increases of 71% countywide and 75% inside city limits, and noted that individual owners' increases varied widely around those averages.
Owners pushed back. INDY Week reported in June 2026 that Durham County Tax Administrator Keyar Doyle cited a record 10,533 appeals. The Board of Equalization and Review, a six-person board, granted enough of them to remove $4.4 billion in assessed value from the county's tax rolls. For the City of Durham, that came to $9 million in lost revenue. The city proposed freezing merit raises for employees and eliminating nine staff positions to close the gap.
The total is less important to a buyer than who got the reductions.
Where the $4.4 billion went
INDY Week analyzed records for more than 10,000 appeals. Commercial properties made up 12% of appeals but received 93% of the reduction in assessed value. Commercial apartments were the biggest single share at 39%. An IBM-occupied data center campus received a $337 million reduction, the largest of any single property. Blue Heron, the firm behind the Ninth Street shopping center anchored by Harris Teeter, received a $15 million reduction. Doyle told the City Council that commercial properties filed more appeals and won larger sums than anyone had expected.
Residential owners filed far more appeals but saw different results:
- The board granted reductions in 83% of commercial cases and 65% of residential cases.
- The lowest-valued residential properties won a reduction 54% of the time. The highest-valued commercial properties won 95% of the time.
- Residential appeals reduced assessed value by $319 million in total, and $153 million of that went to landlords, investors and developers.
- Single-family homeowners paid close to half of the county's property taxes but received about 1% of the dollars returned through appeals.
For a buyer, this means the January 2025 values were corrected unevenly. Most of the downward corrections went to commercial property and investor-owned homes. Assessments on owner-occupied single-family houses mostly stayed as the county first set them.
Why a house next to new construction deserves a closer look
INDY Week also pointed to research from the University of North Carolina's School of Government and DataWorks showing that residential properties are more likely than commercial ones to be overassessed. The paper described a pattern specific to Durham. Sleek new builds often sit right next to aging homes, and waves of construction or renovation can push up the assessed values of the more modest houses nearby.
Durham buyers compare exactly these homes. If you're looking at an older house on a street that has seen infill, the assessed value on the county record could be a little high or quite high for that particular house. Unless the previous owner appealed and won, that value is still on the record, and the tax bill comes with the house.
What the rates do to that number
A higher assessment matters because of the rate applied to it. On June 8, 2026, Durham County adopted a FY2026-27 rate of 57.92 cents per $100 of assessed value. That is 2.50 cents higher than the FY2025-26 rate of 55.42 cents. The 2025-26 rate itself was 3.50 cents above the revenue-neutral rate of 51.92 cents.
Durham City Council kept the city rate at 43.71 cents for FY2026-27. City budget materials put the revenue-neutral rate after the revaluation at 38.23 cents.
Adding the two gives a combined 101.63 cents per $100 for an address inside city limits this fiscal year. At that rate, each $10,000 of assessed value adds about $102 to the annual bill. Suppose two houses are listed at the same price, and one is assessed $40,000 higher because of nearby construction. The higher-assessed house costs roughly $400 more a year, every year until the 2029 reappraisal.
| Durham County | City of Durham | |
|---|---|---|
| FY2025-26 adopted rate | 55.42¢ | 43.71¢ |
| Revenue-neutral rate after the 2025 revaluation | 51.92¢ | 38.23¢ |
| FY2026-27 adopted rate | 57.92¢ | 43.71¢ |
The market has given buyers more time to check
Market conditions this fall make that check easier to fit in. In August 2026, Durham County's median sale price was $426,250, up 1.5% year over year, and the median home took 28 days to sell. In the Durham Regional Association of Realtors August data, days on market were up 12.0% from a year earlier, active inventory was up 16.3%, and months of supply were up 27.2%. Inside Durham city limits, the August median was $424,990 with 30 days on market.
For comparison, the county's median was $399,000 in January 2025, the same month the current tax values took effect. Those are monthly medians across different sales, not the same houses resold. Still, they suggest the overall market hasn't dropped below the 2025 snapshot. Prices are rising slowly and supply is growing. When more homes are listed and each sits a little longer, buyers usually have time to pull a parcel record and compare it with similar homes before they write an offer.
How an appeal works in a year without a reappraisal
Many buyers assume their purchase price will fix an assessment that looks high. Durham County's standard is narrower than that. An owner may appeal if the appraised value is substantially higher or lower than what the property could reasonably have sold for on January 1, 2025. A 2026 or 2027 market value isn't the test. The question is the 2025 value.
Here is the process as Durham County describes it:
- Review the property data and comparable sales in the county's Tax Help portal. To discuss the value with appraisal staff, call 919-560-0300. An informal review usually takes 30 to 120 days.
- If you reach an informal agreement, it is only a recommendation. The Board of Equalization and Review approves the value and makes the final decision at the county level.
- A formal appeal has to be filed before the board stops accepting appeals for the year. In 2026, the deadline was 5:00 p.m. on June 17. The county says the dates change from year to year, so check the 2027 schedule when it is published.
- The board may accept a late application through December 31, but that is at its discretion and not an extended deadline.
None of this is tax or legal advice. For questions about a specific parcel, contact the county tax office or a qualified professional.
"Real property appeals must be filed before the Board of Equalization and Review adjourns from the taking of appeals for the year." That line is from Durham County's appeals page.
Why 2029 matters more than it used to
According to Durham County's FAQ, under state law, counties have to reappraise at least every eight years. Durham has moved to a shorter cycle, which the FAQ says reduces inequity and unpredictable swings in value. The gap between 2019 and 2025 produced the 71% average jump. With four years between 2025 and 2029, the next reset should be smaller. It also means a buyer this fall will pay taxes on the current assessment for at least two more fiscal years before the county reappraises.
FAQ
Does buying a house change its tax value in Durham? No. Between reappraisals, the county can change a parcel's value only in limited cases, such as a zoning change or physical changes to the property. A sale isn't one of them.
Can I appeal right after closing? Yes. Owners can appeal in any year, but the appeal has to show what the home could have sold for on January 1, 2025, and it must be filed before that year's Board of Equalization and Review deadline.
Did residential appeals succeed in 2025? Often, yes. INDY Week found the board granted reductions in 65% of residential cases, compared with 83% of commercial cases.
