In appraisal, there are generally 3 approaches to value - sales comparison, income, & cost.sales comparison approach is typically best and most reliable for residential real estate (4 units or less), income approach becomes more reliable for commercial properties (5+ or more residential units), and cost approach is better suited for newer builds, unique, and/or income producing properties.
