Exam questions using Functional Obsolescence
Every Freehold question shows why the right answer is right — and cites its source.
Which of the following is the clearest example of functional obsolescence?
A cracked foundation needing repair
A five-bedroom home with only one bathroom
A neighborhood in economic decline
Peeling exterior paint on the siding
Show answer & explanation
A five-bedroom home with only one bathroom — Functional obsolescence is a loss in value from outdated or poor design within the property itself, such as too few bathrooms for the bedroom count. Physical wear is deterioration, and neighborhood decline is external obsolescence.

Why is the cost approach typically considered less reliable when appraising a 40-year-old home in an active resale subdivision?
Estimating accrued depreciation on an older structure becomes increasingly difficult and subjective
Land cannot be valued separately from the improvements
The income approach always supersedes the cost approach for older homes
Older homes have no reproduction cost that can be meaningfully estimated by a qualified appraiser at all
Show answer & explanation
Estimating accrued depreciation on an older structure becomes increasingly difficult and subjective — As a structure ages, accurately measuring accumulated physical deterioration, functional obsolescence, and external obsolescence becomes harder and more subjective, reducing the cost approach's reliability compared with ample recent sales data.

A structurally sound older single-family home sits on a large lot in an area recently rezoned for high-density multifamily development. A developer demolishes the home to build an apartment building. This decision most directly reflects:
Functional obsolescence in the cost approach
Physical deterioration of the site
The principle of conformity
A change in the highest and best use of the land
Show answer & explanation
A change in the highest and best use of the land — When zoning and market conditions change, the highest and best use of land can shift; here the land's most profitable legal use became multifamily development, making demolition of the existing home economically rational.
