For assessments made before January 1, 2024, the assessor shall exercise particular care so that personal property as a class on the assessment rolls bears the same relation to statutory value as real property as a class. To assist the assessor in determining the true relationship between real estate and personal property the department of revenue shall make available to local assessors information including figures indicating the relationship between personal property and real property on the last assessment rolls.
