In valuation, the value of land and buildings does not remain constant over time. It may either increase (appreciation) or decrease (depreciation) depending on physical, economic, and environmental factors.
Understanding appreciation and depreciation is essential for:
Property valuation
Cost estimation
Financial planning
Urban development decisions
2.1 Definition
Appreciation is the increase in the value of land or property over time.
👉 It reflects the gain in property value due to favorable conditions.
2.2 Causes of Appreciation
1. Location Advantage
Proximity to city center, metro stations, TOD zones
Better accessibility increases value
2. Infrastructure Development
Roads, metro, water supply, sewerage
Public investments raise land value
3. Economic Growth
Increase in income levels
Higher demand for property
4. Population Growth
Increased demand for housing
Leads to higher land prices
5. Change in Land Use
Conversion from agricultural to residential/commercial
Significant increase in value
6. Government Policies
Smart city projects
TOD policies
Value capture financing
7. Scarcity of Land
Limited supply increases price
2.3 Formula for Appreciation
Future Value=Present Value×(1+r)nFuture\ Value = Present\ Value \times (1 + r)^nFuture Value=Present Value×(1+r)n
Where:
rrr = appreciation rate
nnn = number of years
Example
Present value = ₹10,00,000
Rate = 10%
Time = 2 years
Future Value=10,00,000×(1.1)2=₹12,10,000Future\ Value = 10,00,000 \times (1.1)^2 = ₹12,10,000Future Value=10,00,000×(1.1)2=₹12,10,000
2.4 Importance of Appreciation
Encourages investment
Increases wealth of property owners
Supports urban development financing
Important in TOD and land value capture
3.1 Definition
Depreciation is the decrease in the value of a building or property over time due to wear, tear, or obsolescence.
👉 Mostly applicable to buildings (not land)
3.2 Causes of Depreciation
1. Physical Deterioration
Wear and tear
Aging of materials
2. Functional Obsolescence
Outdated design
Poor layout
3. Economic Obsolescence
Decline in surrounding area
Reduced demand
4. Environmental Factors
Pollution
Flood-prone areas
5. Lack of Maintenance
Poor upkeep reduces value
3.3 Methods of Calculating Depreciation
1. Straight Line Method
Depreciation=Cost−Scrap ValueLifeDepreciation = \frac{Cost – Scrap\ Value}{Life}Depreciation=LifeCost−Scrap Value
Example
Cost = ₹10,00,000
Scrap value = ₹1,00,000
Life = 30 years
Depreciation=9,00,00030=₹30,000/yearDepreciation = \frac{9,00,000}{30} = ₹30,000/yearDepreciation=309,00,000=₹30,000/year
2. Declining Balance Method
Value=Cost×(1−r)nValue = Cost \times (1 – r)^nValue=Cost×(1−r)n
3. Sinking Fund Method
Uses compound interest principles
Funds accumulated for replacement
3.4 Importance of Depreciation
Helps determine actual property value
Important for taxation and accounting
Used in valuation and insurance
Helps in maintenance planning
Land value → usually appreciates
Building value → depreciates over time
👉 Total property value depends on:Total Value=Land Value+Building ValueTotal\ Value = Land\ Value + Building\ ValueTotal Value=Land Value+Building Value
Helps in land use decisions
Supports TOD development strategies
Influences property taxation and redevelopment
Guides investment and infrastructure planning
Land value increases due to metro (appreciation)
Old building deteriorates (depreciation)
👉 Net effect depends on balance between both
Appreciation and depreciation are fundamental concepts in valuation that reflect changes in property value over time. While appreciation enhances land value due to development and demand, depreciation reduces building value due to aging and obsolescence. Understanding both is essential for accurate valuation, investment decisions, and sustainable urban planning.
