Ind. Code § 6-1.1-15-18
(c) To accurately determine market-value-in-use, a taxpayer or an assessing official may:
(2) in a proceeding concerning property that is not residential property, introduce evidence of the assessments of any relevant, comparable property.
However, in a proceeding described in subdivision (2), preference shall be given to comparable properties that are located in the same taxing district or within two (2) miles of a boundary of the taxing district. The determination of whether properties are comparable shall be made using generally accepted appraisal and assessment practices.
