Appraisals and Valuations

“Fair, Accurate and Uniform”

The Appraisal Department’s goal is to equally tax residents by utilizing a process defined as mass appraisal.

  • Mass Appraisal is defined as the process of valuing a universe of properties as of a given date using standard methodology, employing common data, and allowing for statistical testing.

The Trumbull County Auditor’s office routinely collects data that is verified from multiple sources. You may have seen a door hanger or been sent a letter requesting certain important information that may assist the Appraisal Department in recording accurate information from the taxpayers. The department collects data from many avenues to ensure that a fair market value for your property will be assessed. Avenues such as:

  • Field Verification
  • Pictometry or Aerial photography
  • Owner submitted sale/value information i.e. fee appraisal, settlement statement or purchase agreement
  • Local auction results
  • MLS (Multiple Listing Service) data verification

Generally, our State Licensed/Certified Appraisal staff does not have the ability to enter the home. Fee appraisers (bank or single property); on the other hand usually have total access. Our staff appraisers vary in many ways than fee appraisers which are illustrated below:

144,000 properties 1 property

Inspection - Most Exterior only Inspection - Interior and Exterior usually required
2 1/2 years to complete 2 - 3 days turnaround
Equalization with other properties No equalization
Testing of results required No testing necessary
About $15 to $25 per property Roughly $500 for residential property; more for commercial property

The appraisal department must tax the property according to the fair market value. Ohio law requires that a property’s value be established for tax purposes using a uniform approach that produces a fair estimate of what the property would sell for on the open market.
