Durham sits in the same metro as Raleigh but operates as a meaningfully different submarket. The county tax cycle is on its own schedule. The employment base is anchored differently (Duke University and the health system, rather than the broader RTP tech corridor). The housing stock is older. The intown vs. suburban dynamic is more compressed because the city itself is smaller.
If you've underwritten Raleigh and assume Durham works the same way, three things will surprise you.
Durham County's 4-year reappraisal cycle
Durham County reappraised real property effective January 1, 2025. The next reappraisal will be effective January 1, 2029. Durham operates on a 4-year cycle, shortened from the North Carolina state minimum of 8 years.
The cycle math is the same as Charlotte and Raleigh: your year-1 tax is the seller's tax (adjusted for any millage changes the county approves), and the reset arrives at the next reappraisal. Combined millage for property inside the City of Durham runs approximately $1.22 per $100 of assessed value (Durham County around $0.71 + City of Durham around $0.51), or 1.22% of assessed value. This is higher than Mecklenburg or Wake, mostly because Durham County's general fund rate is higher.
Practical implication: if you're buying a Durham property in 2026, you'll have roughly three years of relatively stable taxes before the 2029 reappraisal hits. Underwrite the bump conservatively because Durham's mass appraisal has historically been aggressive at picking up market value movement.
The Duke economy: stable demand, concentrated tenant base
Durham's economy is heavily anchored on Duke University and the Duke Health System. This is a different employment story than Raleigh's broader RTP tech base.
What this means for multifamily:
- Tenant base is more stable. Duke is a major regional employer with low cyclical exposure. Layoffs are rare. Faculty, graduate students, medical residents, and Duke staff form a substantial share of intown Durham renter demand.
- Demand concentrates in submarkets serving Duke. Trinity Park, Watts-Hillandale, Old North Durham, parts of West End see Duke-adjacent tenants. East Durham serves a different demographic.
- Class A new construction has been heavy in the American Tobacco / downtown corridor. Like Raleigh's downtown, this submarket has supply pressure. Class B/C in stable neighborhoods has less.
Older housing stock means more permit-history relevance
Durham has a larger share of pre-1970 housing than Raleigh, especially in the historic neighborhoods around Duke and downtown. Older buildings mean more deferred maintenance, more retrofitted systems, and more permit history to review.
Common issues:
- Knob-and-tube wiring: more common here than in newer Raleigh stock. Insurance carriers may require remediation before writing coverage.
- Galvanized or polybutylene plumbing: similar age-driven issues.
- HVAC: window units instead of central: common in older Durham apartments. Often a value-add opportunity but also an OpEx wildcard during peak summer.
- Roofing and structural: standard older-stock concerns.
Pull the Durham County permit history and cross-reference broker renovation claims thoroughly. The city's Permits and Inspections department is also a useful source for code violations. See the full guide to checking permit history.
Insurance and climate
Durham is far inland (180+ miles from the coast) with very limited hurricane exposure beyond occasional remnant rainfall. Tornado risk exists but is modest. Insurance premiums for standard multifamily run $500-$900/door, comparable to Raleigh.
The older housing stock can push premiums higher on individual properties. Buildings with knob-and-tube electrical, or pre-1970 wood frame without modern code retrofits, may be quoted significantly above the metro average or face non-renewal.
Permit access through Durham County
Durham County's permit portal covers building permits, inspections, and code enforcement for unincorporated Durham. City of Durham permits have a separate portal. Make sure you're searching the right one based on the parcel's jurisdiction.
The standard checklist still applies
The Durham-specific items above sit on top of the general pre-offer due diligence checklist. Permit history, code violations, demographics trajectory, debt service stress test, FEMA flood zone (relevant for parts of New Hope Creek and Eno River-adjacent property) all still matter.
The Durham County tax cycle and the older housing stock are the dominant local considerations. If you've underwritten Raleigh well, Durham requires only the local adjustments above; the methodology transfers.
