I took my first appraisal course in the mid 1980's, before licensing and all the bank failures, given by the Appraisal Institute and both instructors (it was two weeks, 9a-5p, Mon. thru Fri. and they took turns) were MAI's.
While I do not place MAI's on some untouchable pedastel, in those days when you did not need a license, only the very serious about the profession bothered to do all the work necessary to get the designation.
ANYWAY, we were taught that no matter in what form the value is given, the responsibility, research and due dilligence is the SAME.
In other words, no matter whether the value is given to your client on the back of an old envelope or a forty page narrative, it is the responsibility of the appraiser to do ALL THE WORK/RESEARCH necessary to come up to an accurate value.
Your client may only want a one-sentence letter of value, with no description of the neighborhood. HOWEVER, if the site is in a flood zone, or has easements running through it, or anything else that will impact value, you are required to take that into consideration.
The Long and Short of it is: no matter what the client "Basically" needs, your research is the same. The charge should be the same. ALL clients think that the shorter the report, the less work therefore the less fee charged. That's why they keep asking for less and less information and shorter and shorter reports.
Rest assured that if you skip any of the valuation process, Murphy's Law will take over, and that is the report that will wind up getting turned in to the State Board.
The way to discourage the "Basically, I need..." request is to say: "The fee is the same, no matter what you need, because I have to do the same research as a full appraisal" . They will hang up and call the next "sucker".
As far as "BPO's", the brokers THINK they are "bulletproof" because they are hiding behind the fact that the value they give is NOT an appraisal, and NOT allowed to be called an appraisal. As soon as a few get sued over an incorrect value and the word gets around, they will either stop doing them, or demand more money because they will have to do a more thorough job (it's called an appraisal, Mr. Realtor !!!)
Does anyone out there remember hearing that the research is the same, no matter the type of report????
