The "basic" differences in the report "forms" are that more information is required on the "form". Notice the "". A lot more details are filled in. Doesn't NECESSARILY mean that more details are gathered. The BIG difference is in the definition of value. ORDINARILY (meaning not always) when performing a "current market value" appraisal (for whatever reason) you are developing an opinion based on the "most probable sale price a ..." - when doing MOST relocation appraisals you are developing an opinon of the "most probable selling price", appears to be a play on words but SOMETIMES is not. I'm not trying to be difficult, I'm just trying to state the differences CLEARLY so someone doesn't take off for outer space. In a market where everything is selling in a few hours, there PROBABLY won't be much, if any, difference between the two. If you are in a "stable" market with slight appreciation there MIGHT be a slight difference. If you are in a "sluggish" market and so on and so on. Bottom line, it all depends on what you are appraising when. Could be a "little more work" could be A LOT more work. The fee, in MY opinion, is justly higher for relocation appraisals across the board for those times when you break your back, other times you make the "gravy" (never happened to me that often). Besides, if you just TRY and give the relo companies a "sliding scale" you can GUESS what will happen.
