College Grove Property Market Context
The property tax picture in College Grove is shaped as much by Tennessee statewide policy as by anything unique to a city.
Tennessee market character
Tennessee reassesses on a 4-6 year cycle (varies by county), and residential property is assessed at 25% of appraised value. Nashville, Knoxville, and Chattanooga have all posted strong gains with aggressive mass appraisal updates.
How Tennessee handles appeals
Tennessee homeowners appeal first to the county assessor (informal), then the County Board of Equalization, then the State Board of Equalization. The state publishes Assessment Appeal guidelines that make the process accessible.
When to file in College Grove
Informal appeals run through May. County Board deadlines vary but most fall in early-to-mid June.
