Valuation is the process of estimating the value or fair price of real property. There are several purposes for valuation including buying or selling property, taxation, rent fixation, securing loans, and determining compensation amounts. Valuation methods include the rental method, profit-based method, and depreciation method. The rental method capitalizes the net annual income from rent by multiplying it by the years' purchase value. The profit-based method values properties like hotels based on capitalizing the net annual profit. Depreciation is also considered to account for the aging and deterioration of structures over time.
