What aspect does the inspection of the subject and comparables play?
I would expect the inspection of the subject would include the data necessary to meet the agreed upon SOW. Ditto for the comparables. I disagree with Marion that reference to MLS is sufficient, but I could be wrong and she could be right. Personally, I retain the MLS sheets in my workfile just in case.
For a residential property
1. The information about the site and the neighboring uses, as observed, would be relevant and expected
2. The information about the improvement(s), likely including a sketch w/floor plan, and an identification of the construction components, condition, and finishes; as well as any needed repairs
If the 'peer review' of the report, at a minimum shouldn't it inlude an inspection?
That depends. A "peer review" is not necessarily the same as a review for a client with a specific intended use. What is the intended use of the peer review? USPAP compliance? Then an inspection may or may not be necessary depending on the SOW of that review.
Or should the work file be so complete that a "white room" reading the workfile should be sufficient to come to the same conclusions?
Not necessarily. The workfile should be sufficiently complete such that questions regarding the report's data can be supported.
And should the report file so complete that a non-appraiser, state board investigator be able to come to the same conclusion?
Again, this depends on what the state board investigator is tasked with achieving.
If the investigator is tasked with confirming that the workfile contains the necessary information to support the conclusions as reported in the appraisal, that should be fairly straightforward (that's the requirement of the Record Keeping Rule).
If the investigator is tasked with concluding his/her own opinion of value of the subject using only the data contained within the workfile, that may be possible as well, but that's not what the workfile is intended to do (IMNSHO).
Here is the definition of Workfile found in the 2014-2015 USPAP:
From Advisory Opinion 32 (of the same USPAP Version):
Finally, an FAQ from 2014-2015:
The workfile is a compliance mechanism designed to protect the appraiser. It isn't designed (IMO) to serve as the building-blocks of some other (peer or investigator) to replicate the appraisal as I completed it. It is designed to contain the information, data, and (if necessary) outside-the-report analysis to support what I did communicate in the report (my opinions and conclusions).
While maybe some peers or investigators could take all that data and come to the same conclusion, it could be that they cannot. What I must be able to do is to take that data and support the conclusions and analysis I came to. If I can do that, my record keeping requirements are maintained.
If they want to question the credibility of my results and analysis, it isn't going to be based on a Record Keeping Rule violation, it is going to be a SR-1 violation (as in I didn't use the appropriate methodologies or techniques in concluding what I did).
Elliot-
I don't know how much of the specific situation you can share. I can appreciate it being sensitive. I assume this involves an appraiser you know or a decision that has come to your attention. Not knowing the dynamic of your state board, you may want to cautious on how much you want to explore this issue on a national forum. No problem if that is the case.
But if you can share more of the specific, it might assist in getting a more specific answer (or opinion).
