ValuationDepreciation_obsolescenceHARD

A valuer is assessing a 20-year-old industrial building for mortgage security purposes. The building has significant functional obsolescence due to low ceiling heights that don't meet current industry standards. How should this be addressed in the summation approach?

Correct Answer

C) Deduct both physical depreciation and functional obsolescence

In the summation approach, both physical depreciation (due to age and wear) and functional obsolescence (due to outdated design features like inadequate ceiling heights) must be deducted from replacement cost. This ensures the valuation reflects the building's reduced utility compared to modern standards.

Answer Options
A
Deduct physical depreciation based on age alone and ignore the design issue
B
Make no deduction for the ceilings, since they were built to plan
C
Deduct both physical depreciation and functional obsolescence
D
Use the original construction cost with no adjustment for age or design

Why This Is the Correct Answer

The building has two separate losses: wear from 20 years of age, and reduced utility because its ceilings no longer suit modern industrial users. The summation approach deducts both, physical depreciation and functional obsolescence, from replacement cost.
