A single-family residence has only one bathroom, bedrooms that can only be accessed through other bedrooms, and a kitchen with no counter space. These issues represent problems with:

Correct Answer

C) Functional obsolescence

These layout and design deficiencies represent functional obsolescence, which occurs when a property lacks utility or desirability due to outdated design, inadequate facilities, or poor layout that doesn't meet current market expectations.

Answer Options
A
Physical deterioration
B
External obsolescence
C
Functional obsolescence
D
Economic obsolescence

Why This Is the Correct Answer

These layout and design deficiencies represent functional obsolescence, which occurs when a property lacks utility or desirability due to outdated design, inadequate facilities, or poor layout that doesn't meet current market expectations.

Why the Other Options Are Wrong

Option A: Physical deterioration

Physical deterioration refers to actual wear, tear, and decay of building components due to age, use, and exposure to elements. The issues described (poor layout, inadequate facilities) are design problems, not physical damage or deterioration of materials.

Option B: External obsolescence

External obsolescence involves factors outside the property boundaries that negatively impact value, such as nearby industrial facilities, traffic, or economic decline in the area. The problems listed are internal design issues within the property itself.

Option D: Economic obsolescence

Economic obsolescence is essentially the same as external obsolescence - it refers to value loss due to external economic factors beyond the property boundaries. The bathroom, bedroom access, and kitchen issues are internal functional problems, not external economic influences.

FEP Method

Function-External-Physical: Function = design/layout problems INSIDE the house; External = problems OUTSIDE the property boundaries; Physical = actual wear/damage you can SEE and TOUCH

How to use: When you see a question about property problems, ask: Is it a design/layout issue (Function)? Is it caused by something outside the property (External)? Is it physical wear you can touch (Physical)?

Exam Tip

Look for keywords like 'layout,' 'design,' 'inadequate facilities,' or 'outdated features' to identify functional obsolescence questions quickly

Common Mistakes to Avoid

  • -Confusing functional obsolescence with physical deterioration when both involve the building itself
  • -Thinking external obsolescence only refers to economic factors rather than any external negative influence
  • -Assuming all problems in older homes are automatically physical deterioration rather than design obsolescence

Concept Deep Dive

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 a loss in value due to design deficiencies, outdated features, or layouts that don't meet current market standards and buyer expectations. The key is recognizing that these are inherent design flaws in the property's layout and functionality, not wear-and-tear or external factors. Understanding the distinction between these types of value loss is crucial for accurate property valuation and identifying appropriate adjustment methods.

Background Knowledge

Appraisers must distinguish between three main types of depreciation: physical deterioration (actual wear and damage), functional obsolescence (design deficiencies and outdated features), and external obsolescence (negative external influences). Each type requires different valuation approaches and potential remedies.

Real-World Application

In practice, appraisers encounter functional obsolescence when comparing older homes with poor layouts to newer homes with open floor plans, master suites, and modern kitchens. They must quantify the value loss and determine if renovations would be economically feasible to cure the functional issues.
