The document discusses the concepts of value, price, and cost as they relate to real estate valuation. It defines value as the worth or utility of a property, which is measured by price under normal market conditions of supply and demand. Cost refers to what is required to build an asset, which may be more or less than the property's value depending on market factors. The document also outlines different types of property values and notes that the appropriate valuation method depends on the purpose and must account for legal and macroeconomic influences.
