My answer is like a lot of the questions in the appraisal industry, “it depends”. When business is slow, I go on the MLS and build a database of the main adjustments; GLA by property type, price range and market, baths, pools, porches, etc. These are the adjustments I do first. For things like location, quality and condition, they are always by matched pairs with the comps I have. Market adjustments (previously called “time” adjustments, which is wrong) I derive from the 1004MC development. I develop it even with clients who don’t want it. I just keep it in the appraisal file. The reason for this is a ranch in a market may be increasing, decreasing or stable where a colonial may not.
So, yeah, some adjustments I carry over and some are unique to the property, price range or market.
