Anoka County City of Lino Lakes 3 Sales Statistics Defined We have the ability by using statistical analysis to test the accuracy of the assessment. We use these statistics to ensure equity between properties at the neighborhood, municipal and county levels. The Minnesota Department of Revenue also uses these same techniques to test for equity between counties. The primary statistics used are: Median Ratio: This is a measure of central tendency that is the midpoint of a group of sales ratios when arrayed from low to high. The median is a useful statistic as it is not affected by extreme ratios. Aggregate Ratio: This is the total market value of all sale properties divided by the total sale prices. It, along with the mean ratio, gives an idea of our assessment level. Within the city, we constantly try to achieve an aggregate and mean ratio of 94% to 95% to give us a margin to account for a fluctuating market and still maintain ratios within state mandated guidelines. Also referred to as the Weighted Mean. Mean Ratio: The mean is the average ratio. We use this ratio not only to watch our assessment level, but also to analyze property values by development, type of dwelling and value range. These studies enable us to track market trends in neighborhoods, popular housing types and classes of property. Coefficient of Dispersion (COD): The COD measures the accuracy of the assessment. It is possible to have a median ratio of 93% with 300 sales, two ratios at 93%, 149 at 80% and 149 at 103%. Although this is an excellent median ratio, there is obviously a great inequality in the assessment. The COD indicates the spread of the ratios from the mean or median ratio. The goal of a good assessment is a COD of 10 to 20. A COD under 10 is considered excellent and anything over 20 will mean an assessment review by the Department of Revenue. Price Related Differential (PRD): This statistic measures the equality between the assessments of high and low valued property. A PRD over 100 indicates a regressive assessment, or the lower valued properties are assessed at a greater degree than the higher. A PRD of less than 100 indicates a progressive assessment or the opposite. A perfect PRD of 100 means that both higher and lower valued properties are assessed exactly equal. Appeals Procedure Each spring Anoka County sends out a property tax bill (based on the prior year assessment) along with the Notice of Valuation and Classification. Three factors that affect the tax bill are: 1. The amount your local governments (town, city, county, etc.) spend to provide services to your community; 2. The estimated market value of your property; 3. The classification of your property (how it is used). The assessor determines the final two factors. You may appeal the value or classification of your property as described on the next page.
