A No Documentation loan is a mortgage in which the applicant provides a minimum of information. For example, name, address, Social Security number (so credit reports can be pulled), and contact information for an employer, if there is one.

The underwriter decides if the loan is approved based on the applicant's credit history, the appraised value of the house and size of down payment.

No Documentation loans are often ideal for the customer who wants to obtain a loan with minimal paperwork.
