The Land & Building Method, commonly referred to internationally as the Cost Approach or the Depreciated Replacement Cost (DRC) method, is a valuation technique grounded in the economic principle that a rational buyer will not pay more for an existing property than the cost to construct a substitute property of equal utility.
The Core Formula
This approach distinctly separates the value of the land from the value of the physical structures built upon it. The basic formula is:
Key Components of the Calculation
To execute this methodology, a valuer must accurately assess three distinct variables:
- Market Value of Land: The land is valued as if it were vacant and available for its highest and best use. This is typically determined using the Sales Comparison Approach, looking at recent sales of similar vacant plots in the vicinity.
- Replacement or Reproduction Cost: The valuer must estimate the current cost to construct a building of similar utility using modern materials and current construction standards (Replacement Cost), or an exact replica of the existing structure (Reproduction Cost). This includes direct material and labor costs, as well as indirect costs like permits, architectural fees, and standard contractor profit margins.
- Accrued Depreciation: Because the existing building is rarely brand new, the estimated construction cost must be reduced by its depreciation. This includes physical deterioration (wear and tear), functional obsolescence (outdated design features), and economic obsolescence (external factors like zoning changes or declining neighborhood conditions).
When is this Method Used?
The Land & Building Method is particularly crucial for valuing specialized or unique properties that do not frequently change hands in the open market, meaning comparable sales data is scarce. This includes properties like schools, hospitals, religious institutions, custom-built industrial manufacturing plants, and brand-new constructions.
