A house with only one bathroom and three bedrooms suffers from:

Correct Answer

A) Curable functional obsolescence

The inadequate number of bathrooms relative to bedrooms represents functional obsolescence that can typically be cured by adding another bathroom, provided the cost to cure is less than the value added.

Answer Options
A
Curable functional obsolescence
B
Incurable functional obsolescence
C
Physical deterioration
D
External obsolescence

Why This Is the Correct Answer

The inadequate number of bathrooms relative to bedrooms represents functional obsolescence that can typically be cured by adding another bathroom, provided the cost to cure is less than the value added.

Why the Other Options Are Wrong

Option B: Incurable functional obsolescence

Incurable functional obsolescence refers to deficiencies that cannot be economically corrected because the cost to cure exceeds the value added. Adding a bathroom to a three-bedroom house is typically economically feasible and would add significant value. The deficiency can usually be cured by converting existing space or adding an addition, making this curable rather than incurable functional obsolescence.

Option C: Physical deterioration

Physical deterioration refers to the actual wear and tear or physical breakdown of building components due to age, use, or lack of maintenance. The bathroom deficiency is not a physical condition problem but rather a design or layout inadequacy that affects the property's functionality and marketability.

Option D: External obsolescence

External obsolescence (also called economic obsolescence) is caused by factors outside the property boundaries that negatively impact value, such as nearby industrial facilities, traffic patterns, or neighborhood decline. The bathroom deficiency is an internal design issue within the property itself, not an external factor.

The CURE Test

CURE = Cost Under Reasonable Economics. If you can fix the functional problem and the cost is reasonable compared to the value it adds, it's CURABLE functional obsolescence.

How to use: When you see a functional deficiency question, ask yourself: 'Can I reasonably CURE this problem economically?' If yes, it's curable functional obsolescence. Adding bathrooms, updating kitchens, or improving layouts are typically curable.

Exam Tip

Look for the key phrase 'inadequate number of' or 'lacks sufficient' when identifying functional obsolescence questions, then determine if the fix is economically feasible.

Common Mistakes to Avoid

  • -Confusing functional obsolescence with physical deterioration when the issue is design-related rather than wear-and-tear
  • -Automatically assuming all functional obsolescence is incurable without considering the economics of correction
  • -Misidentifying internal design deficiencies as external obsolescence

Concept Deep Dive

Analysis

This question tests understanding of functional obsolescence and the distinction between curable and incurable forms. Functional obsolescence occurs when a property lacks features that buyers expect or has outdated design elements that reduce its utility and value. The key to determining if functional obsolescence is curable or incurable lies in whether the cost to fix the deficiency is less than the value it would add to the property. A house with three bedrooms but only one bathroom represents a clear functional deficiency that modern buyers would find inadequate, as the standard expectation is typically at least two bathrooms for a three-bedroom home.

Background Knowledge

Appraisers must understand the three types of depreciation: physical deterioration, functional obsolescence, and external obsolescence. Functional obsolescence is further divided into curable (cost to cure is less than value added) and incurable (cost to cure exceeds value added) categories.

Real-World Application

In practice, appraisers regularly encounter homes with bathroom-to-bedroom ratios that don't meet current market expectations. They must determine if adding bathrooms is economically feasible by comparing construction costs to the value increase reflected in comparable sales of similar homes with adequate bathrooms.
