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
B) Functional obsolescence
Why this is correct: Functional obsolescence is an impairment due to inadequate or outdated design features that reduce utility. One bathroom, poor bedroom access, and a kitchen with no counter space are all design/layout deficiencies that fail to meet modern market expectations. Why the other choices are wrong: 'External obsolescence' is wrong; that is caused by factors outside the property like a nearby nuisance. 'Physical deterioration' is wrong; that refers to tangible wear, tear, or damage (e.g., a leaky roof). 'Economic obsolescence' is wrong; that is a loss from external economic forces (e.g., plant closure). Exam tip: Functional obsolescence = bad design. If the problem is about layout, flow, or outdated features, it's functional.

Why the Other Options Are Wrong
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Look for keywords like 'layout,' 'design,' 'inadequate facilities,' or 'outdated features' to identify functional obsolescence questions quickly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

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 Functional obsolescence specifically refers to a loss in value due to design deficiencies, outdated features, or layouts that don't meet current market standards and buyer expectations.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.
