If a property is built using inferior grade building materials, this would most likely result in:

When a property is constructed using inferior grade building materials, it primarily affects its overall quality and longevity, leading to functional obsolescence. This term refers to a decrease in a property's value or utility due to factors that make it less desirable or less functional compared to similar properties. Inferior materials can result in various issues, such as shorter lifespan, higher maintenance costs, or inadequate performance in terms of insulation, durability, and aesthetic appeal.

Over time, these issues may cause the property to be less attractive to potential buyers or tenants, thereby reducing its market value and negatively impacting its overall appeal. In contrast, the other options suggest positive outcomes or misinterpretations of the impact of poor materials, which doesn't align with the logical consequences of using inferior building materials.
