The cost approach is a real estate valuation method based on the principle of substitution. It posits that a prudent buyer would pay no more for a property than the cost to acquire a similar site and construct a building of equivalent desirability and utility. The process involves three main steps: (1) estimating the value of the land as if it were vacant, (2) estimating the current cost of constructing the building and other improvements (either as a reproduction or replacement), and (3) estimating and deducting the amount of accrued depreciation from all causes. The land value is then added to the depreciated cost of the improvements to arrive at the total property value.

B. The cost to acquire land only: This is incorrect because the cost approach evaluates the total property, which includes both the land and the improvements (structures) on it.

C. The cost to construct a reproduction only: This is incorrect because it omits the value of the land, which is a critical and separate component in the cost approach formula.

D. The expenses the property is expected to produce for the owner: This is incorrect as it describes the income approach to valuation, which is used for income-generating properties, not the cost approach.

Module on Valuation Approaches, The Cost Approach: The notes define the formula for the cost approach as: Market Value = Replacement Cost New - Accrued Depreciation + Land Value. This explicitly includes both the cost of improvements and the value of the land.
