A 2,400 square foot house has a master bedroom that is 10 feet × 8 feet. This would most likely be considered:
Correct Answer
B) Functionally obsolete
Why this is correct: Functional obsolescence is a loss in value due to poor design or features inadequate for modern use. An 80 sq ft (10x8) master bedroom is extremely small for a 2,400 sq ft house, failing current market expectations for size and utility. Why the other choices are wrong: 'Typical for current construction' is false; modern master bedrooms are much larger. 'Above average for the market' is the opposite; it's below average. 'Adequate for the house size' is incorrect; it's disproportionately small. Exam tip: Tiny master bedroom in a large house = functional obsolescence. Check room size proportionality.

Why the Other Options Are Wrong
Option A: Typical for current construction
An 80 square foot master bedroom is not adequate for a 2,400 square foot house by today's standards. Modern buyers expect master bedrooms to comprise a larger percentage of the total living space, typically 8-12% or more. This size would be considered substandard and would negatively impact the property's marketability and value.
Option C: Above average for the market
This master bedroom size is definitely not above average for the market. At only 80 square feet, it falls well below current market expectations for homes of this size. Above average would suggest the bedroom exceeds typical standards, which is clearly not the case here.
Option D: Adequate for the house size
This bedroom size is not typical for current construction standards. Modern building practices and buyer expectations call for much larger master bedrooms in homes of this square footage. Current construction typically features master suites that are significantly more spacious to meet contemporary lifestyle demands.
The 10% Rule for Master Bedrooms
Remember 'MASTER = Minimum 10%' - A master bedroom should be at least 10% of the total house square footage to avoid functional obsolescence. If it's significantly less, think 'FUNCTIONALLY FLAWED'.
How to use: When you see a room size question, quickly calculate the percentage of total space. If a master bedroom is less than 8-10% of total square footage, consider functional obsolescence as the likely answer.
Exam Tip
Always calculate percentages when given room sizes versus total house size - this helps identify functional obsolescence issues quickly and accurately.
Common Mistakes to Avoid
- -Confusing functional obsolescence with physical deterioration
- -Not calculating the percentage relationship between room size and total house size
- -Assuming any existing feature is 'adequate' without considering current market standards
Concept Deep Dive
Analysis
This question tests understanding of functional obsolescence, which occurs when a property feature fails to meet current market expectations and buyer preferences. Functional obsolescence can be either curable (economically feasible to fix) or incurable (too expensive to remedy). In this case, an 80 square foot master bedroom represents only 3.3% of the total house square footage, which is far below modern standards. Current market expectations for a 2,400 square foot home would typically include a master bedroom of at least 150-200 square feet or more.
Background Knowledge
Functional obsolescence occurs when a property component is inadequate or outdated compared to current market standards, causing a loss in value. It differs from physical deterioration (wear and tear) and external obsolescence (outside factors affecting value).
Real-World Application
In practice, appraisers must identify functional obsolescence to make appropriate adjustments in the sales comparison approach, as properties with outdated features typically sell for less than those meeting current market expectations.
