What is a bank statement loan?
A bank statement loan is a Non-QM mortgage that qualifies self-employed borrowers using 12 or 24 months of bank deposits instead of tax returns.
Self-employed borrowers often show a low net income on tax returns because of legitimate write-offs — depreciation, mileage, business expenses. That real tax strategy hurts when it is time to qualify for a mortgage, because conventional underwriting uses that low net number. A bank statement loan sidesteps the problem: the lender takes your total deposits over 12 or 24 months, applies an expense ratio (the share assumed to go to business costs), and uses the remainder as your qualifying income.
The expense ratio is the key variable. For a sole proprietor using a personal account it is typically 50%; for a corporation or LLC using a business account it can be as low as 10 to 25%, which means more of your deposits count as income. 24 months of statements is the industry standard and gives the most stable picture, though some lenders accept 12 months. These loans work for primary, second home, and investment property — and they pair with ITIN and jumbo programs too.
When to use a bank statement loan
Bank statement loans are the right choice when your deposits clearly show your real income but your tax returns do not.
Your tax returns understate your income
You legitimately write off depreciation, mileage, meals, home office, and business expenses — and your net taxable income drops below what you actually earn. The bank statements show the full picture.
You have 12 to 24 months of consistent deposits
Your business deposits are regular and predictable. The lender averages them over 12 or 24 months, so consistency matters more than any single month.
Your business uses a separate bank account
If you have a business checking account (Corp or LLC), the expense ratio can be as low as 10 to 25%, meaning most of your deposits count as qualifying income.
You want to keep maximizing write-offs
You do not have to change your tax strategy to qualify. The lender looks at deposits, not your tax return, so you can keep doing what your CPA recommends.
Bank statement at a glance
Bank statement loans: did you know?
A few facts that change how self-employed buyers approach qualification.
Tax write-offs are the reason it exists
Depreciation, mileage, and business expenses legally lower your taxable income — and your qualifying income under conventional rules. Bank statement loans look past the tax return to the actual cash flowing into your accounts.
The expense ratio makes or breaks it
A 50% ratio (personal account) halves your deposits as income; a 20% ratio (business account) keeps 80%. Choosing the right account and ratio can double your qualifying income on the same deposits.
24 months beats 12
24 months of statements is the industry standard and gives the smoothest income picture. 12-month programs exist but often carry slightly higher rates or stricter conditions.
Consistency matters more than totals
Underwriters exclude one-time deposits (asset sales, loan proceeds, transfers between your own accounts) and look for steady monthly income. Erratic deposits get averaged conservatively.
Pairs with ITIN and jumbo
Bank statement qualification works inside ITIN programs (no SSN) and jumbo programs (high loan amounts), so self-employed immigrants and high-earning business owners both have a path.
When bank statements are messy, P&L is the alternative
If your deposits are commingled, erratic, or hard to document cleanly, a Profit & Loss loan (CPA-prepared P&L only, no bank statements) may be a better fit. See our Profit & Loss page for when that path makes more sense.

Frequently asked questions
The lender takes your total deposits over 12 or 24 months, subtracts an expense ratio (the share assumed to go to business costs — about 50% for personal accounts, 10 to 25% for business accounts), and divides by the number of months. The result is your monthly qualifying income.
