Unfortunately you may not contact the bank involved....With new regulations the banks have the upper hand and all the financials regarding the sellers are kept private......This is a lenghty process, My best advice to you is have a great relationship with your attorney and agent and express your concerns to them regarding the time factor.
Good luck to you and I hope everything goes well..
As for your question about contacting the bank directly, they are not allowed to discuss anything with you unless they have written permission from the seller.
