About the Research Triangle Park Property Market

Homeowners who believe their Research Triangle Park home is over-assessed have the right to file a appeal directly with Durham County Tax Administration before the Varies (revaluation years) deadline.

Research Triangle Park Property Market Context
Research Triangle Park sits within North Carolina's broader property tax landscape as a city, and local assessments reflect both state rules and county-level mass appraisal practices.
North Carolina market character
North Carolina reassesses on an 8-year cycle (many counties now do 4-year cycles), and the state has seen some of the strongest appreciation in the Southeast. Charlotte, Raleigh, and Asheville markets regularly produce dramatic post-reappraisal shock.
How North Carolina handles appeals
North Carolina homeowners appeal first to the county assessor (informal), then the Board of Equalization and Review, then the North Carolina Property Tax Commission. The state is protest-friendly and clear-process.
When to file in Research Triangle Park
Informal appeals open as soon as notices mail (January-February). The Board of Equalization and Review must adjourn by May 1 in most counties, so file well before then.
