Plenty of self-employed borrowers never opened a separate business account. Client payments, personal paychecks, a spouse's deposits and grocery runs all go through one checking account. That's a co-mingled account, and it changes how you build the worksheet.
First question: personal or business treatment?
Many bank-statement programs have separate rules for personal and business statements, and a lender will typically review a co-mingled account under one of them.
- Personal-statement treatment typically counts eligible deposits without a business expense factor, but the lender may want proof that business expenses are paid elsewhere, or may ask for business statements too.
- Business-statement treatment typically applies an expense factor (or a P&L or CPA-supported factor) to eligible deposits.
Which one applies, and what proof the lender wants, is a program decision. Ask before you build anything; the same statements can produce very different income.
Separate the deposits
Whichever treatment applies, not every deposit in a co-mingled account is self-employment income.
- Tag business receipts. Client payments, merchant settlements, payment-app transfers from customers.
- Tag non-business income. A W-2 paycheck, a spouse's or co-borrower's deposits, benefits. These may be counted another way or not at all.
- Tag non-income credits. Transfers from the borrower's own accounts, refunds, loan or credit-line advances, returned items.
- Note anything you can't identify for a letter of explanation instead of guessing.
Watch for business expenses in the same account
If business expenses run through the account, the lender may treat it more like a business account. Large recurring payments to suppliers, payroll services or equipment lenders are worth flagging early.
Document your work
Write down each exclusion (date, amount, description, reason) and keep the same rules every month. Clear tags make your work easier for the underwriter to follow.
FAQ
Can a borrower qualify with only a personal account?
Many programs allow personal statements. Whether a co-mingled account qualifies, and with what extra proof, depends on the program.
Should the borrower open a business account now?
That's their call and their accountant's. A brand-new account won't have the history the look-back needs, so the existing statements still matter.
Do the co-borrower's deposits count?
They may count as that person's income if documented under the program's rules. Don't fold them into self-employment income.
