What else do I need to do that a lawyer would do if I hired them in buying a foreclosure?

A family member's rental house was foreclosed on. I want to purchase it without a lawyer. I know the title is clean, no lien's, good structure of the home, price and contract negotiation with bank is done. Mortgage approval in the making. Closing on the end of February. I want to make sure all my t's are crossed and i's dotted. What else is needed to complete the lawyer portion of this deal.
