The appraiser has to think about the way that most buyers usually buy a given type of property. What appraisal method do most buyers use for the type of property being valued? This generally guides the appraiser's thinking on the best valuation method, in conjunction with the available data. For instance, appraisals of properties that are typically purchased by investors (e.g., skyscrapers, office buildings) may give greater weight to the Income Approach. Buyers interested in purchasing single family residential property would rather compare price, in this case, the Sales Comparison Approach (market analysis approach) would be more applicable. The third and final approach to value is the Cost Approach to value. The Cost Approach to value is most useful in determining insurable value, and cost to construct a new structure or building.
