Adfinet has Fannie for free (you gotta register).
Freddy has a pretty steep entry fee - I think it is in the range of 700-800 smackeroos and there IS no other source of which I am aware. You can elect to pay the hefty price and be in compliance OR...
I have asked cleints who insist on Freddie forms to provide the appraiser portion of the guidelines. None of THEM had a copy.
Absent that information: I have performed exactly two report with full disclosure not only verbally IN ADVANCE to the client, but also stated in the report, that the guidelines were unavaible from the client, any of my local peers, nor in a timely manner from any other REASONABLE source, and so the appraisal was performed to Fannie Guidelines. Called it a scope issue and went on my way. Client was happy, and with that much disclosure and due dilligence in attempting to acquire the guidelines I think I was covered
In any case with exactly two orders in the last 4 years I wasn't going to pay that much for a 'non-appraisal' -- "Its a house and it's there" kinda form.
