When is the sales comparison approach most effective?

• A. When the subject has unique characteristics and no comparables
• B. When sufficient market data is available to extract and support adjustments
• C. When cost data is readily available
• D. When there are no adjustments needed

Answer: (B)

The sales comparison approach is most effective when there is enough market data from recent, comparable sales to observe how the market prices differences and to support the adjustments you make. With a solid set of comparables, you can quantify how factors like location, size, age, condition, and amenities affect price, and you can apply those observed adjustments to the subject property in a defensible way. This makes the value estimate credible because it’s grounded in actual market behavior rather than guesswork.

If market data are sparse or comparables are not truly similar, the method loses reliability because you can’t extract meaningful adjustments from the market. The cost approach would be more relevant when cost to reproduce or replace the property is the primary consideration, and the idea that no adjustments are needed ignores real market differences that typically influence price.
