Final answer:
Physical deterioration of a property is associated with ordinary wear and tear, resulting from the natural aging process and use. Eccentric design, changing function, and obsolescence may influence property value but don't cause physical decay. Planned obsolescence and capital flight can also impact property usage and lead to neglect.
Step-by-step explanation:
The physical deterioration of a property is most commonly associated with ordinary wear and tear. This is the gradual decline in a property's condition due to everyday use and exposure to the elements. While eccentric design, changing function, and obsolescence can affect a property's value or functionality, they are not directly related to the physical decay of the property's structure. Ordinary wear and tear results from the natural aging process of materials and the normal use of the property by its occupants. For example, as buildings age and materials like wood or masonry are exposed to weather, they will naturally decay. Regular maintenance can slow this process, but cannot stop it entirely. Planned obsolescence, another concept related to deterioration, is more about designing products with a limited useful life, encouraging consumers to replace them sooner than they might due to actual physical wear. Examples include nylon stockings that get runs quickly or technological devices that become outdated due to new advancements. Capital flight can also contribute to deterioration, as people move away from aging buildings, leading to neglect and decay.
