What Is a Bank Statement Loan?

A bank statement loan is a non-QM (non-qualified mortgage) program designed for self-employed borrowers, 1099 contractors, and small-business owners whose tax returns understate their true cash flow due to legitimate business write-offs. Instead of W-2s and tax returns, lenders calculate qualifying income from 12 or 24 months of personal or business bank statements — typically counting 50% of total deposits as income (the other 50% covers business expenses). Bank statement loans charge 1–2% above conventional rates, allow up to 50% DTI, and accept LTVs up to 90% with strong credit. They are not government-backed, not Fannie/Freddie eligible, and held on the lender's portfolio or sold to non-QM aggregators (source: CFPB Ability-to-Repay, Fannie Mae).

How Lenders Calculate Qualifying Income

Personal bank statements: Average monthly deposits × 100% (no expense haircut, but only personal account transfers from business count). Business bank statements: Average monthly deposits × (100% – expense ratio). Standard expense ratio is 50%; a CPA letter or P&L can reduce it to 25–35% for service businesses with low overhead. Some lenders use a hybrid 1099-only program counting 90% of 1099 income with no expense ratio. Recurring transfers between owned accounts are excluded. Cash deposits over a threshold ($1,000–$2,500) may be excluded as unverified. The qualifying income then drives DTI: max 50% means total monthly debt (mortgage PITI + other debts) cannot exceed 50% of qualifying income.

Bank Statement Loan vs Conventional vs DSCR

Bank statement: Self-employed primary residence. 1–2% rate premium. 10–15% down typical. Verifies via deposits. Conventional: Standard W-2 or 2-year tax return self-employed (Form 1084 averaging). Lowest rate. Tax returns must show enough income net of write-offs. Difficult for newly-self-employed or heavy-deduction businesses. DSCR (Debt Service Coverage Ratio): Investment property only. Qualifies on rental income vs mortgage payment, no personal income docs. Most flexible for landlords. Asset depletion: Liquid assets divided over loan term as imputed income. Best for retirees with large savings but low ongoing income. Each program serves a distinct borrower; bank statement is specifically the gap-filler for self-employed primary-residence purchases.

2026 Bank Statement Loan Rate Environment

As of early 2026, conventional 30-year fixed rates sit around 6.75–7.25% and bank statement loans price at 7.5–9.5% depending on credit score, LTV, statement period (12 vs 24 months), and lender. The premium reflects portfolio risk and a smaller secondary market. Borrowers with 720+ FICO and 25%+ down can access the lower end. Going from 12-month to 24-month statements typically saves 0.25–0.5% on rate. Buying down with discount points is common; a 1-point buydown often returns 0.25% rate reduction, payback ~4–6 years. See our discount points calculator to evaluate buydowns.

Who Should Use a Bank Statement Loan

Bank statement loans fit borrowers who: (1) have been self-employed 2+ years (some lenders accept 1 year), (2) show consistent monthly deposits without major gaps, (3) take large legitimate tax deductions that depress AGI, (4) have 700+ FICO and 10–25% down, and (5) want to buy or refinance a primary residence or second home. They are not appropriate when conventional financing works — the rate premium costs $50,000–$150,000 over the loan life on a typical $500K mortgage. Always run conventional first; use bank statement only when tax-return income falls short. Compare with our DTI calculator, payoff vs invest, and no-closing-cost refi.
