You're reading too much into it, Peter. You can use an extraordinary assumption about the interior, if credible assignment results can still be developed
There are circumstances in which I do 2055s on the current form: information about what I don't see myself I take from all the sources recited in the 2055 SOW - I get all that. But I have taken the position that the requirement to verify information from "disinterested sources" that don't have an interest in the current transaction severly limits the number of properties for which verification can be obtained and relied upon.
In a refinance, it certainly isn't the owner; in a sale, it's not the buyer or seller or any of the real estate agents involved. For a refinance transaction, I might rely on a recently expired or closed listing, and verify with the listing agent, since s/he doesn't have an interest in the current transaction.
If an EA about condition or room count or functioning utilities turns out to be contrary to fact, how can assignment results be credible? The SOW says the appraiser must be able to obtain adequate information from reliable sources: if the information reflects something contrary to fact, the default presumtion is that the information wasn't adequate and/or the sources weren't reliable. Perhaps the people who use these appraisers and their shills argue that these can be done and comply with USPAP and GSE requirements, but they are the same ones telling me I can't wish away the certs, limiting conditions and SOW, and I can't EA away something that I am elsewhere bound by the SOW, certifications and limiting conditions to verify.
Regardless, to my admittedly limited way of thinking, the weight of the process - a process in which the second step (after receiving a complaint or notice or whatever) requires me to notify my E&O carrier, prepare to pony up its $1,000 deductible to defend my it - the E&O carrier - against any claim, and then try to find an attorney who understands the nuances of appraisal roulette - far outweighs anything to be gained by accepting these assignments. You may have a different thought process -

- great. I'll still let you buy me a dollop or two of McAllan's - 25 years old, preferably
