The basics
What a bank statement loan is
A bank statement loan is a mortgage for a self-employed borrower. Instead of tax returns, the lender looks at the deposits in your bank statements over one or two years of consecutive months and works out a monthly income from them.
It can help when your tax returns show less income than your business really brings in, for example after write-offs. Your credit, your housing payment history, the money for the down payment and savings, the appraisal and your debts compared with your income are all still checked.
These loans are not sold to Fannie Mae or Freddie Mac, so each program sets its own rules. For a home you live in, the lender must still make a good-faith decision that you can repay the loan.
