Which type of depreciation is considered incurable in most cases?
Correct Answer
C) External obsolescence
Why this is correct: External (economic) obsolescence is caused by factors outside the property boundaries (e.g., bad location, economic decline). It is generally incurable because the property owner cannot control or feasibly fix the external cause. Why the other choices are wrong: Physical deterioration from short-lived items (like a roof) is curable through replacement. Deferred maintenance is curable through repair. Functional obsolescence from a superadequacy (an over-improvement) may be curable if the excess feature can be removed or modified. Exam tip: 'Incurable' often means not financially feasible to fix. External forces are typically beyond the owner's control.
Why This Is the Correct Answer
Why this is correct: External (economic) obsolescence is caused by factors outside the property boundaries (e.g., bad location, economic decline). It is generally incurable because the property owner cannot control or feasibly fix the external cause. Why the other choices are wrong: Physical deterioration from short-lived items (like a roof) is curable through replacement. Deferred maintenance is curable through repair. Functional obsolescence from a superadequacy (an over-improvement) may be curable if the excess feature can be removed or modified. Exam tip: 'Incurable' often means not financially feasible to fix. External forces are typically beyond the owner's control.
Why the Other Options Are Wrong
Option A: Physical deterioration - short-lived items
Physical deterioration from deferred maintenance is typically curable because the property owner can address maintenance issues through repairs, painting, cleaning, and other corrective actions. The cost to cure deferred maintenance is usually less than the value it adds back to the property, making it economically feasible to correct.
Option B: Physical deterioration - deferred maintenance
Functional obsolescence due to superadequacy can often be cured by removing or modifying the excessive feature, though it may not always be economically feasible. Examples include removing an extra bathroom in a small house or converting oversized rooms to more appropriate uses, making this type of depreciation potentially curable.
Option D: Functional obsolescence - superadequacy
Physical deterioration involving short-lived items is highly curable because these components (like carpeting, paint, appliances) are designed to be replaced regularly. The cost to replace short-lived items is typically much less than the value restored to the property, making correction both practical and economically justified.
External = Exit Strategy Impossible
Remember 'EXIT' - External factors require an EXIT strategy because you can't fix what's outside your property boundaries. Think of external obsolescence as problems that make you want to EXIT the property because you can't control them.
How to use: When you see a question about incurable depreciation, immediately think 'EXIT' and look for the answer choice involving external factors or conditions outside the property owner's control.
Exam Tip
Look for keywords like 'outside property boundaries,' 'neighborhood factors,' 'economic conditions,' or 'environmental factors' when identifying external obsolescence questions.
Common Mistakes to Avoid
- -Confusing functional obsolescence superadequacy with external obsolescence
- -Thinking that expensive-to-cure automatically means incurable
- -Assuming all physical deterioration is curable regardless of economic feasibility
Concept Deep Dive
Analysis
This question tests understanding of the three types of depreciation in real estate appraisal and their curability. Depreciation is categorized as physical deterioration, functional obsolescence, and external obsolescence, each with different characteristics regarding whether they can be economically corrected. The key concept is distinguishing between curable depreciation (where the cost to cure is less than the value added) and incurable depreciation (where correction is either impossible or economically unfeasible). External factors that affect property value but originate outside the property boundaries represent the most challenging type of depreciation to address.
Background Knowledge
Appraisers must understand that depreciation curability depends on whether the property owner can control and economically address the cause of value loss. External obsolescence stems from factors like neighborhood decline, environmental hazards, economic downturns, or adverse land uses that are beyond the individual property owner's control or influence.
Real-World Application
An appraiser evaluating a well-maintained home next to a new industrial facility would note external obsolescence from noise, odors, and visual impact. The homeowner cannot relocate the factory or control its operations, making this depreciation incurable and requiring an adjustment in the property's value.
