Valuation of Property and Depreciation Methods
Valuation of property is one of the most important aspects of civil engineering, real estate management, and construction economics. It is the process of estimating the present market value of land, buildings, machinery, and infrastructure assets based on engineering, financial, and market considerations.
Property valuation plays a major role in taxation, mortgage loans, insurance, compensation, rent fixation, investment analysis, acquisition of land, and property transactions.

Introduction to Property Valuation
Valuation is the technique of determining the fair economic value of a property. The value of a property depends upon numerous engineering and economic factors including:
- Location of property
- Road width and accessibility
- Type and quality of construction
- Age of structure
- Durability of materials
- Future development potential
- Demand and supply in the market
- Availability of municipal services
- Architectural planning and aesthetics
Buildings located in commercial or prime urban areas generally possess higher market value compared to buildings located in rural or underdeveloped regions.
Purpose of Valuation
The major purposes of valuation are:
- Determination of fair market value
- Fixation of standard rent
- Assessment of taxes
- Mortgage and bank loan processing
- Insurance claim settlement
- Investment analysis
- Determination of compensation
- Property transfer and legal settlement
Important Terms Used in Valuation
1. Market Value
The probable price that a property would fetch in an open and competitive market under normal conditions.
2. Book Value
The value of a property obtained after deducting accumulated depreciation from the original cost.
3. Scrap Value
The value realized after dismantling a structure and selling the useful materials.
4. Salvage Value
The estimated resale value of a property or machine at the end of its useful life.
5. Assessed Value
The value determined by local authorities for taxation purposes.
6. Potential Value
The enhanced value arising due to future development opportunities or advantageous use.
7. Annuity
A series of equal payments made periodically at regular intervals.
Methods of Valuation
1. Rental Method
In this method, the valuation is based on the net annual rental income generated by the property.
2. Direct Comparison Method
The value of the property is estimated by comparing it with recently sold similar properties in the same locality.
3. Profit Method
This method is suitable for commercial establishments such as hotels, cinemas, restaurants, and shopping complexes where valuation depends upon profit generation.
4. Development Method
Used for properties requiring redevelopment, improvement, or future planning.
5. Depreciation Method
The present value is obtained after deducting depreciation from the original cost of construction.
Depreciation of Buildings
Depreciation is the gradual reduction in the value of a building or machinery due to aging, wear and tear, environmental effects, and technological obsolescence.
- Physical deterioration
- Weathering effects
- Poor maintenance
- Structural defects
- Economic changes
- Technological advancements
- Functional obsolescence
1. Straight Line Method (SLM)
The Straight Line Method is one of the simplest and most widely used methods of depreciation. Equal depreciation is charged every year throughout the useful life of the asset.
Advantages
- Simple and easy to understand
- Uniform annual depreciation
- Easy accounting process
Disadvantages
- Ignores interest on investment
- Not suitable for machinery with rapid depreciation

2. Diminishing Balance Method
This method is also known as the reducing balance method. Depreciation is calculated every year on the diminishing book value of the asset.
Where:
- r = annual depreciation rate
- n = age of asset in years
Advantages
- More realistic for machinery and equipment
- Higher depreciation during early years
- Suitable for industrial assets
Disadvantages
- Complex calculations
- Variable annual depreciation

3. Sinking Fund Method
In the sinking fund method, equal annual installments are deposited into a sinking fund which accumulates with compound interest. At the end of the useful life, the accumulated amount becomes equal to the depreciation amount.
Advantages
- Scientifically accurate method
- Considers compound interest
- Provides future replacement fund
Disadvantages
- Complex calculation procedure
- Requires proper investment planning

4. Quantity Survey Method
This is one of the most accurate engineering methods of depreciation calculation. In this method, each building component is separately analyzed for depreciation.
Components Considered
- Walls
- Roofing
- Flooring
- Doors and windows
- Finishing items
- Services and utilities
Advantages
- Highly accurate
- Component-wise analysis
- Suitable for important structures
Disadvantages
- Time consuming
- Requires detailed inspection
