If the exterior walls of a property are rated "C4" and the roof is rated "C2," what can be concluded?

The correct answer is that the exterior walls show more physical depreciation than the roof does. In property appraisal, ratings such as "C4" and "C2" correspond to specific conditions of elements of a property, with lower numbers indicating better condition. A "C4" rating for the exterior walls signifies that they are in fair condition but have experienced significant wear and may have defects, indicating a higher level of physical depreciation. In contrast, a "C2" rating for the roof indicates it is in good condition, with only minor deficiencies, signifying less physical depreciation.

This comparative analysis of the ratings clearly illustrates that the exterior walls have greater depreciation compared to the roof, supporting the conclusion. Other choices may imply different relationships between the condition ratings or the conditions themselves that do not align with the definitions of the ratings given.
