An appraiser is tasked with valuing a vacant lot that is zoned for commercial development. There are no recent sales of identical vacant commercial lots in the immediate area. However, there are numerous sales of improved commercial properties nearby. Which appraisal method would be most appropriate for valuing this vacant lot?
- ACost Approach
- BIncome Capitalization Approach
- CGross Rent Multiplier (GRM) Method
- DSales Comparison Approach (using improved property sales, adjusting for improvements)
Show answer & explanationAnswer & explanation
Correct answer: D. Sales Comparison Approach (using improved property sales, adjusting for improvements)
Even for vacant land, the Sales Comparison Approach is generally preferred. When direct comparable vacant land sales are scarce, an appraiser can use sales of improved properties and then deduct the value of the improvements (and depreciation) to arrive at a value for the land itself. This is often referred to as the extraction method or abstraction method, a variation within the sales comparison approach for land valuation.
Why the other options are wrong
- A. The cost approach relies on estimating the cost of improvements, which are absent on a vacant lot, making it unsuitable for valuing the land itself.
- B. The income capitalization approach values the income stream of a *developed* property, not a vacant lot.
- C. The GRM method is used for income-producing residential properties and relates price to gross rent, which is not applicable to a vacant commercial lot.
Land Valuation (Extraction Method)
The extraction (or abstraction) method is a technique used within the sales comparison approach to value vacant land when direct comparable land sales are unavailable. It involves analyzing sales of improved properties, estimating and deducting the depreciated value of the improvements, to 'extract' the residual value attributable to the land.
- A variation of the Sales Comparison Approach.
- Starts with the sales price of an improved comparable property.
- Subtracts the depreciated value of the improvements to isolate the land's value.
- Useful when direct vacant land comparables are scarce.
Memory trick: No direct land sales? Improved comps, improvements subtract, land's value exact.
