How is My Estimated Market Value Established?

The Valuation Process


The Assessor's Office estimates market value and classifies more than 29,000 residential, agricultural and commercial parcels each year for property tax purposes. The estimate of market value is as of January 2nd of each year for taxes payable in the following year (Example: January 2, 2018, estimated market value is established for taxes payable in 2019).

Estimate Market Value


The estimated market value should be the most probable sale price of a property in terms of money in a competitive and open market assuming that a buyer and seller are acting prudently and knowledgeable, allowing sufficient time for the sale and assuming that the transaction is not affected by undue pressures.

Classification of Property


The Assessor's Office determines the classification, or use, of each parcel. For instance, property may be residential homestead (owner-occupied), residential non-homestead, apartment, or commercial. Each classification is taxed at a different percentage of market value as set by state statutes.

Each year there are a number of steps followed in order to determine an estimated market value and the classification of property.

View Property


Value and classification of real estate must be established on January 2nd each year. The Assessor’s Office works throughout the year to estimate the market value of each property for the following January 2nd assessment.

New Construction


Any property that had a building permit issued is viewed and its new value estimated for January 2nd following the construction.

Gather Data


Appraisal staff attempt to view the interior and exterior of your property to collect property characteristics used in estimating market value. They list all items that have an impact on market value, such as size, age, quality, basement finish, and extra features, such as fireplaces, walkout basements, etc.

Compute Value


The property characteristics and actual sales information are entered into a mass appraisal system. An estimate of market value is computed based on this information and reviewed by a county appraiser. The estimated market value should be close to the amount the property would sell for if placed on the open market.

Analyze Sales


Each year the Assessor analyzes all sales of property in each jurisdiction. Sales in a 12-month time period before the January 2nd assessment date, (from October 1 to September 30) are reviewed to find out what properties have sold for on the open market. These sales are used, as a guide to help determine what similar properties would likely sell for if they were placed on the market.

The State Board of Equalization requires the overall ‘level of assessment’ to be between 90-105% of market value. Goodhue County consistently meets the State Board’s requirement.

Mail Notices


The Assessor’s Office mails a Value and Classification Notice to each property owner in March of each year. The estimated market value established on January 2nd of each year forms the basis for the following year's tax. For example, the value and classification on January 2, 2017 affect the taxes payable in 2018.

If you feel your valuation and property classification are correct, it is not necessary to contact your assessor.
