A registered valuer is conducting a cost approach valuation on a 15-year-old commercial building. The replacement cost new is $2,000,000, and the total depreciation is estimated at 25%. The land value is $800,000. What is the total property value?
Correct Answer
B) $2,300,000
Using the cost approach: Depreciated building value = $2,000,000 × (1 - 0.25) = $1,500,000. Total property value = Land value + Depreciated building value = $800,000 + $1,500,000 = $2,300,000. The cost approach is particularly useful for newer or special-purpose properties.
Why This Is the Correct Answer
Option B ($2,300,000) correctly applies the cost approach formula. The calculation starts with the replacement cost new of $2,000,000, applies 25% depreciation to get the depreciated building value of $1,500,000 ($2,000,000 × 0.75), then adds the land value of $800,000. This gives the total property value of $2,300,000 ($1,500,000 + $800,000). This method follows established valuation principles and correctly separates land value (which doesn't depreciate) from building value (which does depreciate over time).
Why the Other Options Are Wrong
Option A: $2,200,000
Option A ($2,200,000) appears to result from an error in the depreciation calculation or land value addition. This figure is $100,000 less than the correct answer, suggesting either the depreciation was miscalculated or the land value was incorrectly reduced. The cost approach requires precise calculation of each component.
Option C: $2,500,000
Option C ($2,500,000) incorrectly adds the full replacement cost new to the land value without accounting for depreciation. This calculation would be $2,000,000 + $800,000 - $300,000 = $2,500,000, but fails to properly apply the 25% depreciation to the building component, overstating the property's value.
Option D: $2,800,000
Option D ($2,800,000) represents the sum of the full replacement cost new plus land value without any depreciation deduction ($2,000,000 + $800,000 = $2,800,000). This completely ignores the 25% depreciation factor, significantly overstating the property value and violating fundamental cost approach principles.
Deep Analysis of This Valuation Question
This question tests understanding of the cost approach to property valuation, one of three primary valuation methods used by registered valuers in New Zealand. The cost approach calculates property value by determining the cost to replace the building new, then deducting depreciation to reflect the building's current condition, and adding the land value. This method is particularly relevant for newer properties, special-purpose buildings, or when comparable sales data is limited. The calculation requires understanding that depreciation reduces the building's value from its replacement cost new, while land typically doesn't depreciate. This approach aligns with valuation standards under the Property Law Act and professional valuation practices. The method provides a logical framework for determining value based on the principle that a rational buyer wouldn't pay more for a property than the cost of acquiring equivalent land and constructing a similar building, adjusted for the existing building's condition and age.
Background Knowledge for Valuation
The cost approach is one of three primary valuation methods recognized in New Zealand property valuation, alongside the sales comparison and income approaches. Under this method, property value equals land value plus depreciated building value. Depreciation accounts for physical deterioration, functional obsolescence, and economic obsolescence that reduce a building's value over time. Registered valuers must hold appropriate qualifications and follow professional standards when conducting valuations. The Property Law Act 2008 and valuation standards require accurate, defensible valuation methods. This approach is particularly useful for newer buildings, special-purpose properties, or when market data is limited.
Memory Technique
Remember 'LAND + BUILD = VALUE' where BUILD = Replacement Cost × (1 - Depreciation Rate). Think of it like buying a used car: you pay for the 'land' (the registration/title) plus the 'build' (the car's current value after depreciation from new).
When you see cost approach questions, immediately identify the three components: Land value (stays the same), Replacement cost new (the starting point), and Depreciation rate (reduces building value). Apply the formula: Land + (Replacement Cost × (1 - Depreciation)) = Total Value.
Exam Tip for Valuation
For cost approach questions, always separate land and building values. Calculate depreciated building value first by multiplying replacement cost by (1 minus depreciation rate), then add land value. Double-check your depreciation calculation - 25% depreciation means the building retains 75% of its value.
Real World Application in Valuation
A registered valuer is assessing a 10-year-old medical centre for mortgage security purposes. Comparable sales are limited due to the specialized nature of the building. Using the cost approach, they determine it would cost $1.5 million to build today, estimate 20% depreciation due to wear and functional changes in medical practice, and value the land at $400,000. The final valuation of $1.6 million ($1.5M × 0.8 + $400K) provides the lender with a defensible value based on replacement cost principles.
Common Mistakes to Avoid on Valuation Questions
- •Adding full replacement cost without deducting depreciation
- •Applying depreciation to both land and building values
- •Confusing depreciation rate with remaining value percentage
