Commercial Costs and Depreciation Basics
- Physical deterioration
- Functional obsolescence
- External obsolescence
These are the three what?
Identify the basic components of depreciation.
This is the slow destruction (or wear and tear) of the structural components that goes on every day, from the moment a building is completed.
Physical deterioration.
1/3 major components of depreciation
The physical components of a structure simply wear out over time; they rust, rot, warp, peel, and settle. This process can be hastened by infestation—such as termites and other wood destroying insects and action of the elements—such as moisture infiltration, sun bleaching, and other forces of nature.
The impairment of functional capacity attributed to a particular property according to market tastes and standards.
Functional obsolescence.
2/3 major components of depreciation
The older a building becomes, the more likely it is to have functional obsolescence. However, it is possible to have a 50-year-old building with no functional obsolescence, while a new building may have functional obsolescence while still in the blueprint stage due to poor design.
This type of depreciation comes from outside the boundaries of the property. It is a loss in value from physical or economic causes external to the property.
External Obsolescence
3/3 major components of depreciation
The negative factor causing the loss in value is often identified as locational or economic.
In appraisal, a loss in the value of improvements from any cause; the difference between the cost of an improvement on the effective date of the appraisal and the value of the improvement on the same date.
Depreciation
The period over which improvements to real estate contribute to property value. It is usually shorter than physical life (i.e., how long the building will stand and provide shelter). The period can be extended by means of renovations or remodeling of the improvements.
Economic Life
You can have a building that is still standing (such as an old barn) but is no longer being put to use as it was intended. Its economic life is long gone, but it is still physically standing (until a strong wind comes along and topples it).
This is the estimated period over which existing improvements are expected to contribute economically to a property. What is left of the property to contribute to its usefulness.
Remaining Economic Life
The number of years that have elapsed since the construction of an improvement was completed; also called historical or chronological age.
Actual Age
The age of property that is based on the amount of observed deterioration and obsolescence it has sustained, which may be different from its chronological age.
Effective age
- Market extraction method
- Economic age-life method
- Breakdown method
These are the three primary methods of estimating what?
Accrued depreciation
This method relies on the availability of comparable sales from which you can extract the depreciation.
Market extraction method
1/3 primary methods of estimating accrued depreciation
A method of estimating depreciation in which the ratio between the effective age of a building and its total economic life is applied to the current cost of the improvements to obtain a lump-sum deduction; also known as the age-life method.
Economic age-life method
2/3 primary methods of estimating accrued depreciation
A method of estimating depreciation in which the total diminution in the value of a property is estimated by analyzing and measuring each cause of depreciation (physical, functional, and external) separately.
Breakdown method

The older a building becomes, the greater is the likelihood of it having
all of these answers.
Physical deterioration, functional obsolescence, and external obsolescence can arise over the passage of time and changes in market conditions. A building can suffer from all three forms of depreciation.
