Cost Approach

Definition

The Cost Approach is a method of property valuation that involves calculating the cost to replace or reproduce the property improvements, minus the physical and functional depreciation, and then adding the market value of the land. It assumes that a property’s market value is closely tied to the cost of duplicating the property.

How It Works

1. Determining the Replacement or Reproduction Cost:

   • Replacement Cost: The estimated cost to construct, at current prices, a building with utility equivalent to the existing structure but with modern materials, standards, design, and layout.
   • Reproduction Cost: The cost to construct an exact duplicate or replica of the building using the same materials and construction techniques as the original.

2. Estimating Depreciation:

   • Physical Depreciation: Loss in value due to wear and tear, age, and various other physical factors.
   • Functional Obsolescence: Decrease in value due to outdated design features or construction that is not typical for current use.
   • External Obsolescence: Reduction in property value due to factors outside the property itself, such as neighborhood decline or adverse economic changes.

3. Calculating Land Value:

   • Land value is estimated separately based on its highest and best use. Methods to determine land value include sales comparison, allocation, and land residual techniques.

4. Combining Values:

   • The derived values from the replacement cost, minus depreciation and the current land value, are added together to provide an estimate of the property’s total value.

Examples

1. Residential Home:

   • A newly constructed home in an upscale neighborhood could be appraised by adding the cost to build the home today, identified as the replacement cost, subtracting depreciation relevant to new homes, and adding the market value of the land.

2. Historic Property:

   • Using the Reproduction Cost approach, an appraiser might determine the cost to build an identical structure with the same materials and historical accuracy, subtract depreciation for wear on historical features, and then add the value of the land considering its current market use.

Frequently Asked Questions (FAQs)

Q1: When is the Cost Approach most useful?

• The Cost Approach is most useful for new constructions, special-purpose properties like schools and hospitals, and properties with few comparables.

Q2: How does depreciation affect the Cost Approach?

• Depreciation reduces the replacement or reproduction cost to account for the building’s age, condition, and functionality, ensuring a more accurate valuation.

Q3: Can the Cost Approach be used for residential properties?

• Yes, the Cost Approach can be applied to residential properties, particularly new homes and custom builds without many comparable properties for sale.

Q4: What’s the difference between replacement and reproduction cost?

• Replacement cost refers to building a new structure with similar utility using modern construction techniques, while reproduction cost involves exact duplication of the original structure, materials, and features.

Q5: Is land value included in the Cost Approach?

• Yes, the site or land value is a key component of the Cost Approach and is calculated separately before being added to the improved property’s depreciation-adjusted cost.
