The short answer
A bank-statement mortgage estimates self-employed income from deposits over a lender-defined period instead of from tax returns. Your total deposits are not your qualifying income: transfers, loans, refunds, and non-business items are removed, and the lender applies an expense assumption or uses documented expenses. Credit, down payment, reserves, business history, and the property are still reviewed. Compare it with tax-return qualification before choosing.
Who usually looks at this option?
Business owners whose tax returns show lower net income than the business actually supports, often because of legitimate deductions, depreciation, or a recent growth year. If your returns already qualify you comfortably, a standard loan may cost less and is worth pricing first.
Why your deposits are not your income
The lender starts with deposits, then removes anything that is not earned business revenue. That commonly includes transfers between your own accounts, loan proceeds, credit-card advances, tax refunds, and one-time items such as the sale of equipment. Large or unusual deposits may need a written explanation and supporting records.
Next comes expenses. Some lenders apply a standard expense factor to business deposits; others use a CPA- or tax-preparer-prepared profit-and-loss statement or a documented expense ratio. The method varies by lender and business type, so the same statements can produce different qualifying income at different lenders.
Programs may accept business statements, personal statements, or both, with different treatment for each. Mixing business and personal spending in one account can make it harder to identify which deposits qualify as income.
How many months of statements are needed?
Lenders set their own look-back period. Twelve or 24 consecutive months are common examples, but they are program choices, not a universal rule. A shorter period can help when recent income is stronger; a longer one can smooth out seasonal swings. Either way, a declining trend is likely to draw questions.
What else does the lender check?
- Ownership. Your percentage of the business, which can affect how much of its income counts.
- History. How long the business has operated and whether income is stable or growing.
- Credit and debts. Payment history and existing obligations, including business debts you guarantee.
- Down payment and reserves. Often more than a comparable agency loan, and sourced from verifiable accounts.
- Property and occupancy. Type, value, and how you will use it.
Should you compare tax-return qualification?
Yes. I would run both. Tax-return qualification may offer lower pricing and more program choice if the numbers work. A bank-statement loan can open a path when they do not, usually at a higher cost. Also consider your plans: amending returns or changing deductions only to qualify can have tax consequences, so ask your tax professional before making that decision.
Prepare before you apply
- Complete monthly statements for every account the business uses, with all pages.
- Notes explaining large deposits, transfers, and seasonal patterns.
- Proof of ownership percentage and how long the business has operated.
- Recent tax returns for the side-by-side comparison.
- A target payment you are comfortable with, not only the maximum you might qualify for.
