Estimating Market Value
To estimate the market value of your property, the assessor generally uses three approaches.
The first approach is to find the 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 is usually considered the most important in determining the value of a residential property.
The second approach 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 the improvement is not new, appropriate amounts for depreciation and obsolescence would be deducted from the replacement value. The value of the land then would be added to arrive at a total estimate of the value. An Iowa Real Property Appraisal manual issued by the Department of Revenue is used in the cost approach.
The third approach is 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.
