Residential Assessment Ratio (RAR)
A percentage established by the State Board of Real Property Services according to law, using the ratio of assessed value to the sales price for each usable residential sale in a recent one-year period. Ratios are then listed from highest to lowest; the midpoint (median) ratio is selected as the RAR. The RAR can be used to prove that a residential property is assessed at a higher level than other homes on the assessment roll. Your locality’s RAR indicates at what percent of full value residential properties are assessed. For example, a RAR of 20 indicates that residential properties are assessed at approximately 20 percent of their full value.
