Do you want to switch lenders? Sometimes, once a file develops holes, lenders can be reluctant to move forward even after they are repaired. I am assuming the lien issue is resolved? The attorney's closing protection letter and the title insurance binder is for this specific reason.
If your current attorney has a new title policy and CPL and now it's just the lender, let me know. I'd be glad to close it for you and do my best to meet or exceed what BofA was offering you.
