Which of the following factors is typically associated with economic obsolescence?

Economic obsolescence refers to a reduction in property value due to external factors that affect the marketability or desirability of the property, rather than due to the property's physical condition. The correct answer, which highlights the lack of public transportation facilities, illustrates an external factor that can significantly impact economic conditions surrounding a property.

When public transportation is lacking, it can decrease accessibility for potential buyers or renters. This can lead to reduced demand for properties in that area, resulting in lower market values. In areas where transit options are limited, people might prefer locations that offer better commuting choices, thereby diminishing the appeal of a property.

In contrast, local zoning regulations and changes in market demand are related to regulatory and market conditions but do not specifically signify economic obsolescence. Building maintenance pertains more to physical depreciation or functional obsolescence, as it addresses the structural integrity and upkeep of the property itself, rather than external economic forces. Understanding these distinctions is crucial for identifying cases of economic obsolescence in property valuation.
