Sales Ratio Studies

field_block:node:landing_page:body

The law requires assessors to value property at its most likely selling price. This “estimated market value” divided by the actual sale price equals the Sales Ratio. The Minnesota Department of Revenue uses this ratio to do studies that ensure uniformity and quality of assessments and equalize state aid distribution.

Study [+]

This study compares real estate sales prices to market values calculated by assessors to measure the overall accuracy of their appraisals. The State Board of Equalization and the Minnesota Tax Court use the study results to ensure property assessments are consistent across the state. The Sales Ratio Study is published every year in June. The study uses sales from Oct. 1 through Sept. 30. For example, the 2018 study is based on sales that occurred from Oct. 2017- Sept. 2018.
