Cost Approach Fundamentals: Principles and Key Terms
Chapter 1: Cost Approach Fundamentals: Principles and Key Terms
Introduction:
The Cost Approach is a valuation method that estimates the value of a property by summing the land value and the depreciated cost of the improvements❓. This chapter will delve into the fundamental principles underpinning the Cost Approach and define critical terminology.
- Core Principles of the Cost Approach:
1.1. Principle of Substitution:
The foundation of the Cost Approach rests on the Principle of Substitution. This principle states that a rational buyer will pay no more for a property than the cost of acquiring an equivalent substitute. In the context of the Cost Approach, the substitute is the cost of purchasing the land and constructing a new building with similar utility.
Mathematically:
Value ≤ Cost of Land + Cost of New Improvement
Example:
If a similar vacant lot costs $100,000 and constructing a comparable building costs $400,000, a buyer will not pay more than $500,000 for the existing property, assuming equivalent utility.
Experiment/Practical Application:
Conduct a market survey of recent land sales in the subject property’s area. Obtain current construction costs for similar buildings from local contractors. Compare the sum of these costs to the asking prices of comparable existing properties. Significant discrepancies may indicate factors such as depreciation or market inefficiencies.
1.2. Principle of Contribution:
The Principle of Contribution dictates that the value of each component of a property is determined by its contribution to the overall value. This applies to both the land and the improvements. The cost of an improvement doesn’t necessarily equate to its value.
Example:
An extravagant addition costing $50,000 may only increase the property’s market value by $30,000 if the market doesn’t value the added feature highly.
1.3. Principle of Balance:
The Principle of Balance emphasizes the importance of equilibrium between the various factors of production (land, labor, capital, and entrepreneurship) to achieve maximum value. In the Cost Approach, this manifests as a balance between the land value and the cost of the improvements. Over-improvement or under-improvement relative to the land can diminish value. As the provided text illustrates with residential builders, disproportionate investment in improvements relative to the land value can lead to a substantial loss upon resale.
Example:
Building a $700,000 house on an $80,000 lot may not result in a $780,000 property value because the market might perceive the improvement as excessive for the location and land value.
1.4. Principle of Supply and Demand:
While primarily associated with the Sales Comparison Approach, the Principle of Supply and Demand influences construction costs. Increased demand for construction materials and labor can drive up costs, impacting the Cost Approach. The provided text highlights the dynamic interplay between supply and demand in the broader real estate market, ultimately influencing prices and, indirectly, the cost to build.
- Key Terminology:
2.1. reproduction cost❓:
Reproduction Cost is the estimated cost to construct an exact replica of the existing improvement using the same materials, design, and construction methods, including any outdated features or inefficiencies. This is a hypothetical cost often higher than replacement cost.
Example:
To reproduce a building with asbestos insulation, you’d need to find and pay for asbestos removal and installation, even though it’s an obsolete and potentially hazardous material.
2.2. Replacement Cost:
Replacement Cost is the estimated cost to construct a building with equivalent utility using modern materials, design, and construction techniques. This typically excludes obsolete features and incorporates current building codes and efficiency standards.
Example:
Replacing a building with old knob-and-tube wiring with a new building using modern electrical wiring systems.
2.3. Direct Costs (Hard Costs):
Direct Costs are expenses directly related to the physical construction of the building. These include:
1. Materials: Lumber, concrete, roofing, plumbing fixtures, etc.
2. Labor: Wages paid to construction workers, electricians, plumbers, etc.
3. Equipment: Rental or purchase of machinery used in construction.
2.4. Indirect Costs (Soft Costs):
Indirect Costs are expenses not directly tied to the physical construction but are necessary for the project. These include:
1. Architectural and Engineering Fees: Costs for design, blueprints, and structural plans.
2. Permits and Licenses: Fees paid to local authorities for building permits.
3. Financing Costs: Interest paid on construction loans.
4. Insurance: Coverage for property damage, liability, and worker’s compensation.
5. Surveying and Legal Fees.
6. Construction Management Fees.
2.5. Depreciation:
Depreciation is the loss in value of an improvement due to physical deterioration, functional obsolescence, and external obsolescence❓❓. It is subtracted from the cost new to arrive at the depreciated cost.
Mathematically:
Depreciated Cost = Cost New - Accrued Depreciation
2.5.1. Physical Deterioration:
The loss in value due to wear and tear, age, and deferred maintenance.
2.5.2. Functional Obsolescence:
The loss in value due to inadequacies in design or features that are no longer desirable or efficient.
2.5.3. External Obsolescence (Economic Obsolescence):
The loss in value due to factors external to the property itself, such as neighborhood decline, zoning changes, or economic downturns.
2.6. Entrepreneurial Incentive (Entrepreneurial Profit):
Entrepreneurial Incentive is the profit required to motivate a developer to undertake a project. It represents the return on investment for the developer’s risk, expertise, and effort.
Mathematically (Simplified):
Entrepreneurial Incentive = Total Project Revenue - (Total Project Cost + Normal Profit)
Normal Profit is the profit rate that the market can bear.
- Mathematical Formulas and Equations:
3.1. Cost Approach Value Estimate:
Value = Land Value + (Cost New - Accrued Depreciation) + Entrepreneurial Incentive
3.2. Accrued Depreciation:
Accrued Depreciation = Physical Deterioration + Functional Obsolescence + External Obsolescence
- Practical Applications and Examples:
4.1. New Construction Appraisal:
The Cost Approach is particularly useful for valuing new or proposed construction where market data on comparable sales may be limited.
4.2. Special-Purpose Properties:
Properties with unique characteristics or limited marketability, such as schools, churches, or government buildings, often rely on the Cost Approach due to the lack of comparable sales.
4.3. Insurance Valuation:
Insurance companies use the Cost Approach to determine the replacement cost of a building for insurance purposes.
- Conclusion:
The Cost Approach provides a systematic method for estimating property value based on the cost of creating a substitute property. Understanding the underlying principles and accurately applying the key terminology are essential for effective use of this valuation method. The accuracy of the Cost Approach depends heavily on accurate cost data, realistic depreciation estimates, and a thorough understanding of the market.
Chapter Summary
This chapter introduces the cost approach to real estate valuation, emphasizing its underlying principles and key terminology. The cost approach estimates value❓ by summing the land value❓❓ and the depreciated cost of improvements. A core principle is substitution, which posits that a buyer will not pay more for a property than the cost of acquiring a comparable❓ site and constructing a new improvement. The approach is most applicable when valuing newer properties that represent the highest and best use of the land as though vacant.
The chapter highlights common errors in applying the cost approach, including inaccurate depreciation estimates, land value miscalculations, inflated quality assessments, and neglecting reconfiguration costs related to functional obsolescence. Mastery of construction techniques and costs is crucial for accurate application. The relevance and reliability of the cost approach diminish with older or substandard improvements or when the existing improvements do not align with the site’s highest and best use.
The principle of balance is also discussed, asserting that the cost of improvements must be proportionate to the site’s value. An overimprovement occurs when the investment in the building is disproportionately high relative to the land value, leading to potential losses upon resale. Key terms defined include: cost approach, direct costs, indirect costs, entrepreneurial incentive (or profit), replacement cost, and reproduction cost. The principles of supply and demand are referenced to explain how cost is related to value. The chapter emphasizes that the cost approach theoretically separates land and building values, creating unique considerations not present in the sales comparison or income capitalization approaches.
