Bank statement loans are not typical mortgages. A bank statement program is a home loan program that uses bank statements to calculate a borrower’s income. This is an alternative documentation loan type instead of using tax returns and W-2s in the qualification process. These loans are for self-employed borrowers who typically have substantial tax write-offs that make it challenging to demonstrate the necessary income to prove their ability to repay the loan. The bank statement loan programs use either personal or business bank statements to qualify borrowers.
