A single-family residence has 4 bedrooms but only 1 bathroom, while the market standard for similar homes is 2.5 bathrooms. This deficiency represents:
Correct Answer
B) Functional obsolescence - curable
The inadequate number of bathrooms relative to bedrooms represents functional obsolescence that is typically curable because additional bathrooms can be added, and the cost to cure is usually less than the value added.
Why This Is the Correct Answer
The inadequate number of bathrooms relative to bedrooms represents functional obsolescence that is typically curable because additional bathrooms can be added, and the cost to cure is usually less than the value added.
Why the Other Options Are Wrong
Option A: Physical deterioration
Physical deterioration refers to the actual wear and tear or damage to existing components of a property, such as a leaking roof or worn flooring. The bathroom deficiency is not about the condition of existing bathrooms but rather the inadequate number of bathrooms relative to market expectations.
Option C: Functional obsolescence - incurable
Functional obsolescence would be incurable if the cost to add bathrooms exceeded the value that would be added to the property. However, adding bathrooms to a 4-bedroom home is typically economically feasible and adds significant value, making this a curable deficiency.
Option D: External obsolescence
External obsolescence refers to factors outside the property boundaries that negatively affect value, such as proximity to a landfill, airport noise, or economic decline in the area. The bathroom deficiency is an internal design issue, not an external factor.
The FIX-IT Test
F-unctional obsolescence is I-nternal, X-tra features missing. If you can reasonably FIX IT and add value, it's curable; if fixing costs more than the value added, it's incurable.
How to use: When you see a property missing expected features (bathrooms, bedrooms, modern layouts), think 'Can I FIX IT profitably?' If yes, it's functional obsolescence - curable.
Exam Tip
Look for keywords like 'inadequate,' 'insufficient,' 'lacks,' or 'below market standard' - these often indicate functional obsolescence. Then determine curability by considering if the fix is economically feasible.
Common Mistakes to Avoid
- -Confusing functional obsolescence with physical deterioration when existing features are in poor condition
- -Assuming all functional obsolescence is curable without considering the cost-to-cure versus value-added analysis
- -Misidentifying internal design deficiencies as external obsolescence
Concept Deep Dive
Analysis
This question tests understanding of the three types of obsolescence in real estate appraisal: functional, physical, and external. Functional obsolescence occurs when a property lacks features that buyers expect or has outdated design elements that reduce its utility and value. The key distinction is whether the obsolescence is curable (economically feasible to fix) or incurable (too expensive to remedy relative to the value gained). In this case, having only 1 bathroom for a 4-bedroom home creates a functional deficiency that impacts the property's marketability and utility.
Background Knowledge
Appraisers must understand the three types of obsolescence to properly adjust comparable sales and estimate depreciation. Functional obsolescence specifically relates to design deficiencies or outdated features that reduce a property's utility compared to current market standards.
Real-World Application
In practice, appraisers frequently encounter homes with bathroom-to-bedroom ratios below market expectations. They must determine the cost to cure (add bathrooms) versus the value increase to properly adjust comparable sales and estimate the subject property's value.
