Remember that mortgage lenders are in the business of making money by making loans. If you have provided complete and accurate documentation you are one step closer to getting your home.
Do not be concerned if your lender comes back with more questions or wants additional documents. This is not unusual and does not mean that you are being rejected. For that reason it is to your advantage to remain available for communication from the time you file for the loan until you get the decision. Whatever information the lender wants, make sure that you quickly provide everything asked for.
