A building with a total economic life of 50 years is currently 15 years old but has an effective age of 10 years due to recent renovations. What is the remaining economic life?
Correct Answer
B) 40 years
Remaining economic life is calculated using effective age, not actual age. With a total economic life of 50 years and effective age of 10 years: 50 - 10 = 40 years remaining.
Why This Is the Correct Answer
Option B is correct because remaining economic life is calculated by subtracting the effective age from the total economic life. The effective age of 10 years (not the actual age of 15 years) is used because renovations have improved the building's condition. Therefore: 50 years total economic life - 10 years effective age = 40 years remaining economic life. This reflects the property's actual condition and expected future utility.
Why the Other Options Are Wrong
Option A: 35 years
Option A incorrectly uses the actual age instead of effective age in the calculation (50 - 15 = 35), failing to account for the positive impact of recent renovations on the building's condition and remaining useful life.
Option C: 45 years
Option C appears to subtract only 5 years from the total economic life, which has no basis in the given information and ignores both the actual age and effective age calculations entirely.
Option D: 50 years
Option D suggests no economic life has been consumed, which would only be true if the building were brand new with zero effective age, contradicting the given 10-year effective age.
TREE Method
Total - Remaining = Effective (TREE). Just like a tree's remaining life depends on its health condition, not just its age, remaining economic life = Total economic life - Effective age (not actual age).
How to use: When you see economic life questions, think TREE and remember that renovations make a building 'healthier' like a well-maintained tree, so always use effective age in your calculation.
Exam Tip
Always look for keywords like 'renovations,' 'improvements,' or 'well-maintained' that signal effective age differs from actual age, and remember the formula: Remaining Economic Life = Total Economic Life - Effective Age.
Common Mistakes to Avoid
- -Using actual age instead of effective age in the calculation
- -Confusing effective age with remaining economic life
- -Assuming renovations don't impact the economic life calculation
Concept Deep Dive
Analysis
This question tests the critical distinction between actual age and effective age in real estate appraisal, specifically how renovations and improvements can extend a property's useful life. The concept of remaining economic life is fundamental to the cost approach and depreciation calculations. Understanding that effective age reflects the property's condition relative to its actual chronological age is essential for accurate valuation. The calculation always uses effective age because it represents the property's true functional condition, not just how many years have passed since construction.
Background Knowledge
Effective age represents the age of a building based on its condition and utility, which can differ from actual age due to maintenance, renovations, or neglect. Total economic life is the period over which a building is expected to contribute to property value, while remaining economic life is the future period of economic utility.
Real-World Application
An appraiser evaluating a 20-year-old office building that underwent major HVAC and facade renovations would assign it an effective age of perhaps 10 years, meaning it has more remaining economic life than its actual age would suggest, directly impacting the depreciation calculation in the cost approach.
