Appraisal - Market value comparison approach: The majority of residential appraisals use this technique, comparing recent sales of similar properties ('comparables' or 'comps' in real estate jargon) and adding and subtracting the differences in value of the same features in the subject property. For example, if a house of the same size on the same street and in the same condition as the subject property recently sold for $200,000, but this 'comparable' had a triple garage and a finished basement and the 'subject' does not; the appraiser calculates the market value of these features (say, $12,000 in total) and deducts this amount from $200,000, giving an 'adjusted value' of $188,000. This is usually done with at least three 'comparables' and either averaged or the middle ('median') value used.
Depreciated cost approach: This technique is a supporting measurement of value used by many appraisers, whereby the land value is estimated and added to an estimate of the depreciated building value. Where there are few comparables available, relatively more weight might be given to this method.
