Final answer:
The factor that influences value by considering a property's function is the functional use, where form follows function in design and economic value assessment. An efficiently functioning property is of higher value due to its effective service and operation.
Step-by-step explanation:
The factor that influences value by considering the property's function refers to the functional use of the property. The functionalist perspective in architecture, for instance, dictates that form follows function, meaning the design of a building or any property primarily depends on its intended use. For example, a warehouse is designed to efficiently store goods, whereas a house is designed to meet living needs.
In this context, certain economic principles also apply. When assessing the economic value of a property, one must consider its function in terms of how well it serves its intended purpose and the efficiency of its operation. Similarly, in the broader economic landscape, functions often relate to cause and effect, affecting the movement of goods and services and ultimately the health of the economy.
