More Than One Highest and Best Use
Highest and best use is not necessarily just one specific use. It is possible that several uses will
prove equally profitable. For example, two different uses may return the same net income to a
property.
Interim or Transitional Uses
A property's highest and best use may be prepared to change in the foreseeable future. The use to
which a parcel is put before its transition to a future highest and best use is known as an interim
or transitional use. An interim use typically continues for a relatively short period of time before
converting to a succeeding use. Interim uses appear in transitional areas where older uses are
yielding to new ones. For example, given appropriate zoning and growth trends, an agricultural
area on the outskirts of a city may be in transition to residential use. The current agricultural use
is an interim use. Or, an older residential district in a city may be in transition to commercial use.
The current residential use is an interim use. As a final example, in downtown areas, vacant lots
are often used for parking; however, as market conditions warrant, the lots will be developed and
utilized much more intensely. In such cases, the parking lot use is an interim use.
The total market value of a property in transition is based on both its interim and succeeding use.
The total value of transitional property is the sum of: (1) the present worth of the net real
property benefits from the interim use over the period of interim use; (2) the present worth of the
salvage value of the interim improvements, if any, at the termination of the interim use (or the
negative present worth of the cost of removing the improvements, if this exceeds the salvage
value); and (3) the present worth of the net future real property benefits from the succeeding
highest and best use.
However, an interim use may or may not contribute to current property value. An interim use
contributes to current property value if the gross income derived from the use exceeds operating
expenses related to the use. For example, an interim agricultural use of land often produces a net
return above that of unused vacant land, thereby contributing to the total market value of the
transitional property.
