You really, really should let a lawyer at least review the docs. I'm not YOUR lawyer, but I am a real estate litigation attorney and this is the space I work in day in and day out (a big part of my practice is nationwide large commercial mortgage foreclosures - think malls, office towers, etc. all across the county). I can't tell you how many times we run into issues with foreclosure or enforcement because the documents aren't done right. The docs we have the most problems with are the "Laser Pro" and other computer-generated form documents that non-lawyers (like smaller banks or title companies) generate, fill in the blanks, and sign. They're objectively terrible documents, rarely prepared truly correctly, and it frequently costs the Lender more money for us to fix the issues than it would have to just do it right on the front end. Banks get away with it because of their high volume, relatively low default rates, and the occasional screw up just gets swallowed up by the high volume of ones where the loans never default. But you don't have the benefit of a huge number of loans to offset a bad one.
Escrow agents are usually NOT lawyers (at least not practicing ones). Yes, they see financing documents all the time, and usually have some understanding of the basics (esp on the mortgage itself), but they rarely understand all the nuances, etc. That's just not their job. All they care about is insuring that the Mortgage creates a valid lien. They don't care of the other terms in your documents are well done, enforceable, etc.
