Bank Statement Loans Explained: Qualifying With 12 or 24 Months of Deposits
See how bank statement loans use 12 or 24 months of deposits to qualify self-employed borrowers, including LTV tiers, FICO minimums, and how the program works.
What a Bank Statement Loan Looks at Instead of Your Tax Return
If you run your own business, you already know the disconnect: your tax preparer's job is to legally minimize what you owe, which means your adjusted gross income on paper can look a lot smaller than what actually lands in your accounts every month. A bank statement loan is built around that reality. Instead of pulling your tax returns and running an IRS Form 4506-C transcript request, we qualify you using an average of your monthly deposits — either a 12-month or 24-month lookback, whichever window better reflects how your business actually performs.
This program is one of the more established non-QM options in our lineup, and it's worth understanding both how the math works and where the tradeoffs are before you decide whether it fits your situation.
Choosing Between the 12-Month and 24-Month Lookback
Both lookback periods are available, and the one you pick can change your qualifying income meaningfully.
- 12-month average pulls only your most recent year of deposits. If your business has grown in the last twelve months, this window usually produces a higher qualifying income than a longer lookback would.
- 24-month average blends two full years together. If last year was unusually strong but the year before was softer — or vice versa — the 24-month average smooths that out.
There's no single right answer here. A contractor who just landed a bigger commercial client might prefer the 12-month window to capture that growth. A business owner who had one slow year during a supply disruption, but has otherwise been consistent, might prefer the 24-month average so that slower year doesn't disproportionately hold back today's file. Part of what we do when you take our quiz and talk through your file is model both lookback periods and use whichever produces the stronger, more accurate picture of your income.
Personal Statements vs. Business Statements
The type of account you use to qualify changes how we calculate income:
| Statement Type | Expense Factor | What It Means |
|---|---|---|
| Personal bank statements | 0% | 100% of your average monthly deposits count toward qualifying income |
| Business bank statements | ~50% | Roughly half of deposits are treated as business overhead; the remainder counts as income |
The business-statement expense factor exists because deposits into a business account include revenue that also has to cover payroll, inventory, rent, and other overhead — costs a personal account generally doesn't carry. If you're not sure which statement type will produce the stronger qualifying number for your file, our income calculator can give you a directional estimate before you apply, and which type makes sense is worth talking through directly with your loan officer.
Credit, Loan-to-Value, and Loan Amount Guidelines
Bank statement loans require a minimum FICO score of 640. Maximum loan-to-value (LTV) scales down as the loan amount goes up:
| Loan Amount | Maximum LTV |
|---|---|
| Up to $1,000,000 | 90% |
| Up to $2,500,000 | 85% |
| Up to $5,000,000 | 80% |
This structure lets the program serve everything from a modest starter-home purchase to a larger jumbo-range file, with the down payment requirement increasing as the loan size grows.
How This Compares to a Conventional Loan
A conventional loan calculates your income directly from your tax returns, averaging two years of net self-employment income after deductions. That process rewards borrowers who show high income on paper and can work against borrowers who run their businesses tax-efficiently. A bank statement loan sidesteps that entirely by looking at cash flow instead of taxable income, which is why it has become one of the standard paths for self-employed borrowers whose returns don't tell the full story.
Reserves Are Documented Separately
The bank statements used to calculate your qualifying income are separate from the asset statements used to verify funds for your down payment, closing costs, and any required reserves. Underwriting will ask for standalone documentation of those funds, sourced and seasoned like any other mortgage file, in addition to the 12 or 24 months of deposit history used for income.
Property Use and Loan Purpose
Bank statement loans aren't limited to primary residences. The program is available for:
- Primary residences
- Second homes
- Investment properties
You can also use this program for a purchase, a standard cash-out refinance, or a delayed-financing cash-out (paying cash for a property and then recouping funds through a later mortgage). Eligible property types include single-family homes, townhomes, condos, pre-construction properties, and non-warrantable condos that wouldn't qualify for conventional financing. Eligibility extends to U.S. citizens, permanent residents, non-permanent residents on a qualifying work visa, and borrowers closing in an LLC.
The Interest-Only Option
Some borrowers on this program choose an interest-only payment structure for a set introductory period, which can be useful if you want to keep monthly cash outflow lower while reinvesting in your business or managing seasonal income swings. This isn't the right fit for every borrower, and it's a conversation worth having directly with your loan officer so you understand exactly how the payment changes once the interest-only period ends.
Who Tends to Fit This Program
Bank statement loans are typically a good starting point for:
- Business owners whose tax returns show significant deductions relative to actual cash flow
- Borrowers whose income is inconsistent month to month but strong on average
- Anyone who has been self-employed long enough to have a full 12 or 24 months of account history to document
If your income comes primarily through 1099s rather than a business bank account, our 1099 income loans program may be a more direct fit. And if most of your net worth sits in savings, investments, or retirement accounts rather than flowing through as deposits, asset-based qualification is worth a look too.
