Put me in with the scope of work guys. I am on the probate list in one of my counties and all they want from a reporting standpoint is the value and signature on the inventory sheet. When I first started I asked about the extent of the inspection (interior or exterior) and was told to just do the best I can. I have never had any follow up questions, but for what it is worth, I do keep a file with comp info, worksheet, etc.. I also take the time to do it right because it is the right thing to do, I am putting my signature on it, and the heirs may depend on it for other matters. Unfortunately this is in a county with mostly acreage sites and a wide variety of home styles, quality, etc,.
You should be able to do a large volume of similar scope work in a conforming/urban area with 6 comps within 3 blocks and in an area you have been doing for 20 years. Especially if you are able to batch them up so you are in a small section of town on any given day and do those areas enough that you were there for 6 appraisals last week, 4 the week before, 5 the week before that........
There used to be an old saying. "I knew what it was worth when I pulled into the driveway, The hard part is proving it." 15 a day even under the limited scope does not sound like there is much proving going on, but I suppose I could give them the benefit of the doubt that they are using a qualified assistant to compile data and fill out the paperwork so all the appraiser has to do after the inspection is the mental work and some basic calculations.
