Which of the following is NOT one of the four main approaches to property valuation?

The Sales Comparison Approach is actually a subset of the Market Approach, which evaluates property value based on recent sales of similar properties in the area, while the Market Approach itself encompasses broader techniques that compare properties' market values.

The four main approaches to property valuation typically include the Cost Approach, where value is determined based on the cost of replacing or reproducing a property; the Market Approach, which estimates value based on comparable sales; and the Income Approach, which focuses on the income-generating potential of an investment property.

By recognizing the Sales Comparison Approach as part of the broader Market Approach, it becomes clear that the correct answer cannot be this option, making it evident that the question was aiming to identify one that stands apart from these established methods.
