With a letter of attestation, something fairly new from fannie, i think the lender doesn't understand that this is in leau of the appraiser re inspecting. They don't need the appraiser, period. That is the purpose of this attestation which is mainly used for simple items. The appraiser request is like a double positive, but without paying the appraiser. I would do it for my direct clients for free, if they asked. They all treat me very well. But that is a business decision.
That being said, where does it say that is has to be on a 1004d form. Since we are allowed to revise the appraisal anytime with a new signature date, then you can put that in the original appraisal with the proper statements. Some of you try to act like appraiser rules perfectionists.
