I have always kept a copy of the plans and specs in the workfile. I realize that many appraisers just take a photo and then give them back.. Maybe this is ok but I prefer a legible copy. Here is my question Is it a requirement to keep plans and specs in your workfile for the 5 year time length? I have always thought that it was and have kept them, I have a bank telling me otherwise. I didn't hit the number and the borrower wants them back.
