What is the value increment resulting from combining properties?

The correct answer is that the value increment resulting from combining properties is known as plottage value. This concept refers to the increase in value that occurs when two or more adjacent parcels of land are combined into a single larger parcel. When properties are assembled, the resultant single parcel often has a greater total value than the individual values of the separate parcels when sold independently. This increased value can arise due to improved development opportunities, better zoning adjustments, or enhanced utility for larger projects.

In contrast, assemblage is the act of combining these properties, not the value gain resulting from it. Progression value refers to the increase in value of a property as a result of its proximity to higher-valued properties, while investment value is the worth of a property based on an investor's specific investment criteria and objectives. Thus, while these terms are related to property values, plottage value specifically describes the increase in value derived from the combination itself.
