A few documents are needed to get a loan file through underwriting. Some of the information will be gathered online or over the phone. A lot of it will already be stated on some documents you'll provide, like employer address which can be found on a pay stub. While the list looks long, it won't take much effort to round them up. The lists below will help you keep track. Your loan officer will also indicate which items will not be needed and also help you prioritize which items to send in first.
