A 2,400 square foot home has only one bathroom, no dining room, and a kitchen with 1950s-era cabinets and appliances. This represents:
Correct Answer
A) Functional obsolescence
Why this is correct: Functional obsolescence is a loss in value due to outdated design, features, or layout relative to market expectations. Why the other choices are wrong: Economic obsolescence is caused by external market factors. Physical deterioration is wear and tear. External obsolescence is caused by factors outside the property. Exam tip: Functional = internal design flaws; External = outside neighborhood/economic factors.
Why This Is the Correct Answer

Why the Other Options Are Wrong
FEP Obsolescence Triangle
Remember 'FEP': Functional = Flawed design/layout, External = Environmental factors, Physical = Physical wear/damage. Think 'Function Follows Form' - if the form (design/layout) doesn't function well for modern living, it's functional obsolescence.
How to use: When you see a question about property deficiencies, ask: Is it design/layout issues (Functional)? Outside factors (External)? Or actual damage/wear (Physical)? Use FEP to categorize the problem type quickly.
Exam Tip
Look for keywords that indicate design inadequacy versus physical damage. Words like 'outdated design,' 'inadequate layout,' 'insufficient rooms,' or 'poor floor plan' typically point to functional obsolescence.
Common Mistakes to Avoid
- -Confusing functional obsolescence with physical deterioration when kitchen appliances are mentioned
- -Thinking external obsolescence applies to any negative factor rather than specifically external influences
- -Assuming all outdated features represent physical deterioration rather than design inadequacy

Analysis
This question tests understanding of the three types of obsolescence in real estate appraisal: functional, external, and physical deterioration. Functional obsolescence specifically refers to deficiencies in a property's design, layout, or features that make it less desirable compared to current market standards and buyer expectations. The key is recognizing that these are design and layout issues inherent to the property itself, not wear and tear or external factors. Understanding the distinction between these types of obsolescence is crucial for accurate property valuation and identifying sources of depreciation.
Background Knowledge
Appraisers must understand the three main types of depreciation: physical deterioration (wear and tear), functional obsolescence (design deficiencies), and external obsolescence (outside negative influences). Functional obsolescence can be either curable (economically feasible to fix) or incurable (too expensive to remedy relative to the value added).
Real-World Application
In practice, appraisers encounter functional obsolescence frequently in older homes that haven't been updated to meet modern living standards. They must estimate the cost to cure (if economically feasible) or apply appropriate depreciation adjustments when the obsolescence is incurable, directly impacting the property's final appraised value.
