I'm not sure that a lawyer could tell you anything from the closing documents at signing about where the loan will end up.  The closing package is a classic "take-it-or-leave-it" proposition that typically isn't available for a thorough review until shortly before the borrower is ready to sign (so much for the RESPA compliance for lenders).  While I support the idea of borrowers having attorneys review their loan on their behalf, I don't know how an attorney could make it either economically, practically or ethically viable, given the industry's actual practices which make a fetish out of formal, but meaningless, disclosures, yet deny borrowers the two things that would enable them to understand what their doing: time and the ability to bargain on ALL of the key terms.

On the ethics matter, how would an ethical attorney advise her client on the lender not providing documents in advance on the one hand, and then telling the borrower that the documents have to be signed today, or no deal?    This kind of representation is more than a matter of paying an attorney a few bucks.
