What is Market Value?

Market value of a property is an estimate of the price that it would sell for on the open market on January 1st of the year of assessment. This is often referred to as the “arm’s length transaction” or “willing buyer/willing seller” concept.

To be considered market value, the following conditions would apply:

How does the Assessor estimate Market Value?

To estimate the market value of your property, the Assessor generally uses three approaches.

  1. The first approach is to find properties that are comparable to yours which have sold recently. Local conditions peculiar to your property are taken into consideration. The assessor also uses sales ratio studies to determine the general level of assessment in a community, in order to adjust for local conditions. This method generally referred to as the MARKET APPROACH and usually considered the most important in determining the value of residential property.

  2. The second approach is the COST APPROACH and is an estimate of how many dollars at current labor and material prices it would take to replace your property with one similar to it. In the event improvement is not new appropriate amounts for depreciation and obsolescence would be deducted from replacement value. Value of the land then would be added to arrive to the total estimate of value.

  3. The INCOME APPROACH is the third method used if your property produces income such as an apartment or office building. In that case, your property could be valued according to its ability to produce income under prudent management; in other words, what another investor would give for a property in order to gain its income. The income approach is the most complex of the three approaches because of the research, information and analysis necessary for an accurate estimate of value. This method requires thorough knowledge of local and national financial conditions, as well as any developmental trends in the area of the subject property being appraised since errors or inaccurate information can seriously affect the final estimate of value.

Why Values Change

After properties have been appraised, the values are analyzed to ensure accurate & equitable assessment. Iowa State law requires that all real property be reassessed every two years. The current law requires the reassessment to occur in odd numbered years. Changes in market value as indicated by research, sales ratio studies and analysis of local conditions as well as economic trends both in and outside the construction industry are used in determining your assessment.

If you disagree with the assessorís estimate of value, please consider these two questions before proceeding, as outlined below:

  1. What is the actual market value of my property?
  2. How does the value compare to similar properties in the neighborhood?
    1. If you have any questions about the assessment of your property, please contact the assessor’s office.
    2. A written protest may be filed with the Board of Review, which is composed of either three or five members from various areas of the assessing jurisdiction, whom are familiar with local market conditions and trends. The Board operates independently of the assessor’s office. It has the power to confirm or to adjust either upward or downward any assessment.
    3. If not satisfied with the Board’s decision, appeals may be filed with the Property Assessment Appeal Board or to district court within 20 days after adjournment or May 31st whichever date is later.
    4. If dissatisfied with a Property Assessment Appeal Board decision, the decision may then be appealed to the district court. As in the past, a property owner my appeal the Board of Review’s decision directly with the district court and forego filing with the Property Assessment Appeal Board.

Tax Levies & Assessed Values

There are a number of different taxing districts in a jurisdiction, each with a different levy. Each year the County Auditor determines for that district a levy that will yield enough money to fund the budgets that pay for schools, police and fire protection, road maintenance and other services. The tax levy is applied to each $1,000 of a property’s taxable value. The value determined by the assessor is the assessed value and is the value indicated on the assessment roll. The taxable value is the value determined by the Auditor after application of state-ordered “rollback” percentages for the various classes of property, as well as deductions for any applicable exemptions or credits, resulting in the value indicated on the tax statement. When comparing the value of your property with other properties always compare with the value on the assessment roll or the Assessor's property record cards and not the value indicated on the tax statement.

Exemptions & Credits

Iowa law provides for a number of exemptions and credits, including Homestead Credit, Military Exemption and Business Property Tax Credit. It is the property owner’s responsibility to apply for these as provided by law. If the property you were occupying as a homestead is sold, or if you cease to use the property as a homestead you are required to report this to the assessor in whose jurisdiction the property is located. For properties currently receiving the Business Property Tax Credit, changes in ownership or other changes that would affect the requirements for the credit, requires reapplication for the credit.
