Rutherford County Assessor Rob Mitchell Launches Bid for Tennessee Comptroller, Pledging Independent Oversight
Rob Mitchell, Rutherford County's property assessor since 2012, announced a campaign for Tennessee comptroller, criticizing the current administration's handling of property classifications and appeals. The comptroller is elected by the General Assembly, which re-elected Jason Mumpower to a third term in January 2025.
RUTHERFORD COUNTY, Tenn. â Rutherford County Property Assessor Rob Mitchell announced Friday that he is seeking the office of Tennessee comptroller, a position chosen by a joint vote of the state House and Senate for a two-year term.
Mitchell, who has served as the county's assessor since 2012, said in a Nov. 6 campaign release that he wants the office to prioritize fiscal responsibility, transparency and independent oversight. The comptroller's office audits state and local government entities and oversees Tennessee's financial and administrative management.
"The Comptroller's office should serve as an independent watchdog for Tennessee taxpayers, not as a policymaking body that creates unnecessary financial burdens for local governments," Mitchell said in the announcement.
His campaign points to disagreements with the current comptroller's administration over property classifications, appeals and state authority over local assessors. Mitchell said 179 administrative hearings in Rutherford County could have been avoided through more consistent application of state law.
The dispute follows a state review of Rutherford County's assessment practices. In March 2025, the State Board of Equalization found the assessor's office out of compliance in several areas, including property classification, corrections to square-footage errors and the assessment of new construction. The board ordered the county to review property records and make required corrections.
In March 2026, the Division of Property Assessments informed Mitchell that the required steps had been completed after the county made corrections involving more than 6,000 parcels. The division said continued improvements and internal controls would be needed to remain in compliance.
Tennessee's property-assessment system assigns classifications based on how property is used. State law sets assessment percentages for different property types, while county assessors appraise and classify property. Taxpayers can appeal assessments through local and state processes, including hearings before an administrative judge.
Mitchell said his priorities would include reducing administrative costs, applying state law consistently and improving relationships with local governments.
Lawmakers re-elected Jason Mumpower to a third term as comptroller in January 2025. The next comptroller election will occur through a joint vote of the General Assembly.
