Which of the following is NOT a method used for estimating site value?

The environmental impact assessment is not a method used for estimating site value in real estate appraisal. Instead, it is a process that evaluates the potential effects of a proposed project or development on the environment, including factors such as air and water quality, wildlife, and cultural resources. While it may influence land development and use decisions, it does not provide a direct estimate of the financial value of a site.

In contrast, the other methods listed are commonly employed to determine site value. The land residual method calculates site value based on the income generated by the property after deducting the costs associated with improvements. The sales comparison method estimates value based on the recent sale prices of comparable properties, providing a market-supported valuation. The ground rent capitalization method focuses on the income derived from leasing land and capitalizes that income to estimate the land's worth. Each of these methods is inherently linked to deriving a monetary value for a site within the context of real estate appraisal, highlighting the distinction between them and environmental impact assessments.
