In neighborhood analysis, which factor would be considered an external obsolescence influence?
Correct Answer
C) Construction of a landfill nearby
External obsolescence refers to value loss caused by factors outside the property boundaries. A nearby landfill would negatively impact property values and is beyond the property owner's control, making it external obsolescence.
Why This Is the Correct Answer
External obsolescence refers to value loss caused by factors outside the property boundaries. A nearby landfill would negatively impact property values and is beyond the property owner's control, making it external obsolescence.
Why the Other Options Are Wrong
Option A: Outdated kitchen in the subject property
An outdated kitchen represents functional obsolescence, not external obsolescence, because it relates to the property's internal design and layout features that can be updated or modernized by the property owner.
Option B: Functional layout problems
Functional layout problems are classified as functional obsolescence since they involve the property's internal design efficiency and floor plan issues that affect the property's utility and desirability from within.
Option D: Deferred maintenance on the subject
Deferred maintenance represents physical deterioration or physical depreciation, as it involves the property's physical condition and maintenance issues that can be addressed through repairs and upkeep by the property owner.
The PFE Boundary Rule
Remember PFE: Physical (inside property - wear/tear), Functional (inside property - design flaws), External (outside property boundaries). Think 'External = Outside the fence' - if you can't fix it from inside your property boundaries, it's external obsolescence.
How to use: When you see a depreciation question, ask yourself: 'Is this factor located inside or outside the property boundaries?' If it's outside and beyond the owner's control (like a landfill, airport noise, or economic decline), it's external obsolescence.
Exam Tip
Look for keywords indicating location and control - external obsolescence factors are always outside the property and cannot be fixed by the individual property owner, while physical and functional issues can typically be addressed through renovation or repair.
Common Mistakes to Avoid
- -Confusing functional obsolescence with external obsolescence when the issue involves property design or layout
- -Misclassifying curable vs. incurable depreciation - external obsolescence is typically incurable
- -Failing to recognize that external factors must be outside the property boundaries to qualify as external obsolescence
Concept Deep Dive
Analysis
External obsolescence is one of three types of depreciation in real estate appraisal, representing value loss caused by factors outside the property boundaries that are beyond the property owner's control. Unlike physical deterioration (wear and tear) or functional obsolescence (design flaws), external obsolescence stems from neighborhood or environmental influences that negatively impact property desirability and value. This type of depreciation is typically incurable because individual property owners cannot remedy the external conditions causing the value loss. External obsolescence factors include environmental hazards, economic decline in the area, traffic congestion, incompatible land uses, and other locational disadvantages.
Background Knowledge
Appraisers must understand the three types of depreciation: physical deterioration (wear and tear), functional obsolescence (design deficiencies), and external obsolescence (outside influences). This classification system is essential for the cost approach to value, where appraisers estimate reproduction/replacement cost new and then subtract all forms of depreciation to arrive at the depreciated value.
Real-World Application
When appraising a home near a newly constructed waste treatment facility, the appraiser would research comparable sales before and after the facility's construction to quantify the external obsolescence impact on property values, as this environmental factor is permanent and beyond any individual homeowner's ability to remedy.
