"Exceptions. Nonattorney Notaries who are specially trained, certified, or licensed in a particular field such as real estate, insurance, and escrow may advise others about documents in that field, but in no other."

Even though it says so in writing, I think it would be wise to use good judgement and prudence regarding how (and IF) we "advise" the borrowers about their loan documents, even if we believe we know the answer. At the expense of appearing ignorant, I have saved many closings by saying nothing more than, "Call your loan officer". Good luck.
