Is there a standard commercial mortgage loan application?

While some commercial mortgage lenders will accept a form 1003, most have their own application. A form 1003 is a standard uniform mortgage application supplied by Freddie Mac / Fannie Mae. However, it is a residential application and any commercial lender that will accept it will also require other documentation to support it. While a 1003 contains a personal financial statement, it is not designed to report on the property's cash flow. An income (or operating) contains that information.
