Meaning of Physical obsolesces:
Obsolesces negatively affect the value of the property. In other words, it reduces the value of the property. Further, obsolesces are of three types in real estate property. And these are Physical, functional, and external (Locational or economical) obsolesces. However, in this article we will discuss physical obsolesces in detail.
Physical obsolesces mean loss or decline in value of the property by usage and passage of time. In other words, physical obsolesces occur when the physical aesthetics of the property deteriorates and requires replacement or repairs. Hence, physical obsolescence generally relates to the property’s age and its use.

Every property with the passage of time and usage requires regular maintenance. However, if regular maintenance is not undertaken, then it affects the durability and longevity of the property rapidly. Moreover, there are many factors that can relate to physical obsolesces like normal wear and tear, improper design of construction, inappropriate materials and components used in the construction of the property, lack of proper maintenance by the owner, etc. Like sunlight, fire, wind, storms, floods, and earthquakes are natural factors causing damage to the property. In simple words, physical obsolesces are those damages to the property that are visible and can be identifiable. And this can be in control by regular maintenance, proper planning, and the right choice of material and construction method.
Types of Obsolesces
In this article, our focus is on the physical obsolesces of real estate/ property. However, let us at least understand the definition of other types of obsolesces too. And these are:
It occurs when a property loses its value due to its design, architecture, style, inadequate or outdated amenities, size, etc. Hence, we can say it is because of the internal factors of the property.
It happens when the price of the property deteriorates due to external factors. And these factors could be the changes in the local traffic pattern, creation or coming up of public nuisance utilities and noisy surroundings, construction of sewage plants, powerhouses, jails, etc.
Types of physical obsolesces:
Physical obsolesces can be classified into two categories,
- Curable obsolesces
- Non curable iobsolesces
Curable obsolesces mean damages to the property that is repairable and replaceable economically. The cost to repair the damaged component or part of the property does not exceed the loss in value. In other words, the gains on the value of asset/property, resulting from the repair will offset the cost to repair. Hence, the cost of repair, increase in the value of and the economic life of the property are the main factors to consider for taking decisions with regard to curable obsolesces.
Curable obsolesces includes repainting, doors and window replacement, carpet replacement, broken tiles, leakages or plumbing fixtures, wall proofing, roof repairs, deferred maintenance etc.
Incurable obsolesces are not economical to repair or replace as cost to repair exceeds the gain in value.
Such obsolesces items include structural frameworks, foundation or ceiling structure. If the foundation of the property is faulty, it would consider as incurable obsolesces. As in this situation tear down the building and start from scratch is more feasible rather than to repair.
The structural frameworks of property deteriorate at different rates, based on the length of time they are expected to last. Hence, the appraiser classifies incurable obsolesces on life expectancies of the building components as short-lived incurable obsolesces and Long lived incurable obsolesces.
Short-lived items whose expected remaining economic life is shorter than the remaining economic life of the entire structure. This includes electrical and mechanical systems, furniture, and fixtures that wear out faster than the rest of the property. This also includes items that are not yet ready to replace.
Long-lived items whose expected remaining economic life is equal to the remaining economic life of the entire structure. This includes foundation frames, roof, and floor structural, etc.
Methods of determining physical obsolesces:
There are three basic methods of calculating physical obsolescence:
- Market extraction method/Sales comparison method
- Age-Life method
- Breakdown method/Observed condition method
A) Market extraction method/Sales comparison method:
This method is particularly useful in mass appraisal. In this method, the appraiser compares property with other recently sold property having similar characteristics in size, shape, design, and in the same location. The following steps are present in the determination:
- Identify comparable sales
- Establish sale date, sale price, site area and land value.
- Adjust comparable by adding or deducting value.
- Determine net improvement value by subtracting land value from total sale price.
In addition certain limitations to the Market extraction method:
- Difficult to find appropriate comparable
- Require ample amount of data
- Less flexible compared to other methods
B) Age-Life method:
This method is also called the straight-line method as in this method effective age of the property is estimated and every year equal percent of depreciation provision is made. So that at the end of the asset life total depreciation provided for is equal to 100% cost of the property.
Similarly, it is used most of the time and easy to determine the physical deterioration. In this method, the ratio of effective life to total economic life will be calculated and multiplied by the replacement cost of the property.
The formula for Age Life Method
The following formula will give us a more clear understanding:
Percentage of depreciation = Effective age ÷ Total economic life
Dollar amount of depreciation= Replacement cost for similar new property × Percentage of depreciation
Total economic life= Effective age + Remaining Economic life
Let’s understand terminologies used in the above formula:
Effective Age of the property is determined based on the current condition of the property rather than actual age. In other words, it means how old the property looks. This directly influences with the maintenance of the property. If the property is well maintained then the effective age will be less as compared to the actual age.
Actual Age is the number of years passed from the date of structure built.
Economic life refers to the estimated period the property remains useful and contributes to the value of the property. However, the remaining economic life is the difference between economic life and the effective age of the property. Renovation and remodeling can affect the physical life and extend the remaining economic life of the property.
Reproduction or Replacement cost is the cost incurred to construct or replace the existing part or function of the improvements.
Let us understand with example:
Reproduction cost new – $ 100,000
Expected economic life – 50 years
Current effective life – 10 years
Depreciation = $100,000 * 10/50
Limitation of Age/Life method:
- It does not consider curable obsolesces separately.
- It considers the same economic life for both short-lived items and long-lived items.
i) Modified age -Life method:
This method is useful when the building has a major amount of curable physical or functional depreciation.
In this method, curable obsolesce is considered as 100% depreciable and incurable components calculated by age – life method.
The formula for estimating depreciation under the modified age life method is as follows:
Incurable depreciation =
(Replacement/reproduction cost new – cost to cure curable items) ×
Effective age ÷ Total economic life
Total depreciation= Curable depreciation + Incurable depreciation
Limitation of modified age life method:
- Although more accurate but does not allow for individual difference in remaining economic life on different components. As uses single age/life ratio for every components of improvements.
C)Breakdown method/Observed condition method:
In this method, a separate analysis of each form of depreciation (physical, functional, economical) requires to be done. In using this method one needs to judge condition and expected physical life of each component of the building including short-lived items, long lived items, curable and incurable.
Steps in Breakdown method:
- Identify curable physical deterioration and cost to cure these items established
- Estimate curable short lived physical and functional obsolesces.
- Age and life expectancy of long lived items identified and incurable physical obsolescence estimated.
- Estimating impact of external obsolescence
- Add up total depreciation and estimating property value.
Limitation of breakdown method:
- This method is complex and time consuming, hence not useful in mass appraisal.
- Requires detailed analysis and judgement concerning the condition and life expectancy of each component.
