Since you already have a lender, you should be asking him/her this question. You will get the best answer to loan process questions from them.
If you are asking about the buying process of a foreclosure, again I would direct you to the professional that you are already working with. Hopefully you chose your agent because they are knowledgeable and good at what they do.
I know this doesn't sound like I am giving you anything new here, but you have already done more for yourself than most at this point. You have hired 2 professionals that are (should be) experts in their field. That's a great start.
