What does "functional obsolescence" indicate in property appraisal?

Functional obsolescence refers to a reduction in a property's value due to outdated design features or an inefficient layout that no longer meets the current needs or preferences of buyers. This concept encompasses elements like inadequate room sizes, lack of modern amenities, or architectural styles that have fallen out of favor. Over time, as consumer preferences evolve and technology advances, properties that do not adapt can experience a decline in desirability, leading to diminished market value.

In contrast, losses in value related to changes in market demand or oversupply represent different concepts. Market demand fluctuations occur for various reasons, such as economic shifts or demographic changes, while market saturation refers specifically to an oversupply of similar properties. An increase in value due to improvements is also a different scenario altogether, focusing on enhancements that positively impact a property's appeal and functionality. Recognizing functional obsolescence is vital for appraisers as it helps provide an accurate assessment of a property's current value relative to consumer preferences and market standards.
