Which of the following is not one of the four Develop Cost Methods?

The Market Approach is not one of the four Develop Cost Methods. The reasoning behind this is that the Market Approach focuses on assessing the value of property based on the prices of similar properties that have been sold recently, rather than directly calculating costs associated with the development of the property itself.

In contrast, the Quantity Survey method estimates costs based on detailed measurements and the cost of materials and labor for the project. The Trended Original Cost method takes into account the original cost of the property and adjusts it for inflation or depreciation over time. Comparative Unit method assesses costs based on per-unit measures, such as cost per square foot, derived from similar projects.

Each of these methods is focused on cost estimation related to development, whereas the Market Approach seeks to infer value from the marketplace, positioning it outside the scope of development cost methods.
