For the purpose of appraisal, land is defined as real property exclusive of improvements. Improvement is defined as anything done to land with the intention of improving its value.

In Pima County, land is valued using the Market Approach.  In this approach, value is estimated by comparing sales and adjusting them for differences in characteristics to indicate a value for the subject property.

By statute, an Affidavit of Property Value, completed by the Buyer and Seller or their agent, is required to be appended, at the time of recording, to each deed evidencing a transfer of title, or contract relating to the sale of real property.  The total consideration paid for a property, and other required information on the Affidavit of Property Value is collected, and that data is used to establish values for tax purposes.

For ad valorem purposes, a single property appraisal or “fee appraisal” is not an efficient way to establish values for the large number of properties that must be valued each year.  Therefore, the Assessor’s office determines values using a mass appraisal method.

Mass Appraisal Overview

Mass Appraisal is the process of establishing values on groups of properties as of a given date using standardized procedures and statistical testing.  Its purpose is the equitable and efficient appraisal of property for ad-valorem purposes.  This involves data collection, market analysis, valuation and quality control.

Some of the characteristics that are considered in the valuation of land are location, zoning, size, topography, flood plain, configuration and legal restrictions.

Land is most typically valued on a per square foot, per acre or per site basis.  The unit of comparison used by the assessor would normally be the same as the unit of comparison used by buyers and sellers in the marketplace for a particular type of property – i.e. residential, industrial or commercial.

In Pima County, Mobile Home/RV Parks are valued after considering cost, income and market data.  Each park is categorized into different value grades based on the number and quality of amenities, and its location, all of which affect the level and duration of income stream it is capable of generating.  In this way, similar properties are compared against each other.
