Self-Employed Bank Statement Mortgage Qualifier
Bank statement mortgages let self-employed borrowers qualify on deposit history rather than tax returns. Lenders take 50-75% of deposits as qualifying income.

Bank statement mortgages are non-QM (non-qualified) loans designed for self-employed borrowers whose tax returns understate true income (legitimate business deductions reduce taxable income but not cash flow). Lenders qualify you on 12 or 24 months of business bank deposits with an expense-factor adjustment, rather than on Schedule C or K-1 income. Rates run 1-3% above conventional but the option exists when tax returns won't work.
How Bank Statement Underwriting Works
Lenders pull 12-24 months of business bank statements and total all deposits. They subtract an expense factor (default 50%, sometimes 40% with CPA letter, sometimes 30% for service businesses) to estimate net income. The result is your qualifying monthly income. Personal account deposits typically don't count unless commingled with the business — and commingling can disqualify the application entirely. Some lenders allow Profit & Loss statement underwriting as a hybrid (P&L plus statements to verify), which can produce higher qualifying income for businesses with seasonal cash flow.
Maximizing Qualifying Income
(1) Separate accounts: keep all business deposits in a dedicated business checking account. (2) Annotate transfers: large internal transfers, capital contributions, or loan proceeds should be documented so they don't skew deposit averages. (3) CPA expense letter: provide a CPA-attested letter stating actual expense ratio — some lenders accept 25-30% expense for high-margin businesses (consulting, software, professional services). (4) 12 vs 24 months: pick the period that shows higher deposits. If 2025 is your best year, 12-month underwriting captures that. If income is steady, 24-month gives more stable numbers and slightly better pricing.
