I'll go along with Randy 110%! My question is what is the purpose of the review?
If it's to see if a form is correctly filled out, as explained above. If you can develop a checklist and train someone to look at exact steps, it may make your job easier.
If the process also includes fair lending, a credit or credit review officer might be better. Although you know underwriting, unless you are actively in the loop, there could be similarly situated loans where a more experienced loan officer (with greater authoirity) made, or exceptions to policy where your application was denied but a less qualified borrower was approved. Those are the ones that sneak up on you, especially that with all the data reported via HMDA-LAR, the regulators can do an electronic fair llending review of your loans and you have no knowledge it's going on.
