What factor does not directly relate to functional obsolescence?

Functional obsolescence refers to a decrease in a property's value due to functional limitations or inadequacies within the property itself. This includes aspects that impair how well the property serves its intended purpose.

Outdated design features, excessive partitions, and lack of functional space all represent internal issues that directly affect how efficiently a property can be utilized, contributing to functional obsolescence. For example, outdated design features can make a property less appealing or impractical for modern uses, while excessive partitions can hinder the flow or usability of space. Similarly, a lack of functional space can lead to a property being less desirable because it cannot meet the needs of its occupants effectively.

In contrast, location changes do not directly pertain to the internal characteristics of the property. While changes in the surrounding area can influence overall market value, they are not a reflection of the property’s functional performance or layout. Therefore, they fall outside the scope of functional obsolescence, making them the correct answer in this context.
