The concept of highest and best use is seen as a basic and integral part of market value appreciation. It is defined as the determination of the most probable use of an immovable property, which is physically possible, financially feasible, permitted by law, and brings the property to its highest value. The use that is not permitted by law and is not physically possible cannot be considered as the best use with high efficiency. This method allows appraisal in many areas, such as the effects of attrition and obsolescence in buildings, optimal improvement (reclamation) and renovation of land, and the granting of optimal zoning rights to parcels in zoning practice. In markets where there is a serious imbalance between supply and demand, or where there is an excessive fluctuation, the most highest and best use of property may be a right that can be used in future years.
