Lesson 5: Bank Statement Loans — When Tax Returns Don’t Tell the Whole Story
For many self-employed borrowers, there can be a significant difference between taxable income and the actual cash flow generated by their business.
That isn’t necessarily a problem with the business.
It may simply be the result of how the tax code works.
Business owners often legitimately reduce taxable income through ordinary business expenses, depreciation and other deductions. Those deductions can be valuable at tax time—but they may create a very different picture when the borrower applies for a traditional mortgage.
Conventional mortgage underwriting generally relies heavily on tax returns and the income that can be documented under agency guidelines.
But what happens when the tax returns don’t tell the whole story?
That’s where bank statement loans may provide another option.
What Is a Bank Statement Loan?
A bank statement loan is generally a Non-QM mortgage program designed primarily for self-employed borrowers.
Instead of relying primarily on tax returns to determine qualifying income, the lender analyzes deposits shown on the borrower’s personal or business bank statements over a specified period—commonly 12 or 24 months, although programs vary.
The objective is to develop a reasonable picture of the borrower’s qualifying income based on documented cash flow.
This doesn’t mean income or employment verification disappears.
Quite the opposite.
The lender still needs to establish that the borrower has a legitimate, ongoing business and a reasonable source of income. What changes is how that income is documented and calculated.
And that distinction can make a substantial difference for the right borrower.
Personal Bank Statements vs. Business Bank Statements
One of the first questions is which bank statements should be used.
Some lenders offer programs using personal bank statements. Others use business bank statements. Some lenders have separate programs for each.
The underwriting approach can be very different.
Personal Bank Statements
With a personal bank statement program, the lender generally reviews eligible deposits flowing into the borrower’s personal accounts and determines which deposits can reasonably be considered income.
Transfers between accounts, borrowed funds and other non-income deposits generally cannot simply be counted as qualifying income.
Business Bank Statements
For a business owner whose revenue is primarily deposited into business accounts, a business bank statement program may make more sense.
But gross business deposits aren’t necessarily the same thing as personal income.
The lender generally must account for the expenses required to operate the business.
That brings us to one of the most important parts of BUSINESS bank statement lending:
the expense factor.
Why the Expense Factor Matters
Suppose a business receives substantial deposits each month.
Those deposits represent gross business revenue—but the business also has expenses.
Payroll. Rent. Materials. Insurance. Equipment. Advertising. Utilities. Transportation. Supplies.
A lender therefore may apply an expense factor to eligible business deposits to estimate how much of that revenue is available as qualifying income to the borrower.
For example, if eligible business deposits averaged $40,000 per month and a lender applied a 50% expense factor, approximately $20,000 per month might be available for income qualification, subject to that lender’s complete guidelines.
But here’s where things become interesting:
Not every lender uses the same expense factor—or even the same methodology for determining it.
Depending on the lender, program and type of business, another expense factor may be available. Some lenders may permit additional documentation from a CPA, tax preparer or other qualified third party to support the business’s actual expense structure.
The resulting difference in qualifying income can be substantial.
Bank Statements Aren’t the Only Documentation
The name “bank statement loan” can make these programs sound simpler than they really are.
The bank statements may be the primary tool used to calculate income, but lenders generally still need to verify the existence and operation of the borrower’s business.
Depending on the lender and program, that additional documentation might include:
- A CPA or tax preparer letter
- A current business license
- Verification that the business is active
- Secretary of State or other public business records
- A lender-specific business profile or business narrative
- Information about the borrower’s ownership percentage
- The nature of the business and how it generates revenue
- The length of time the borrower has been self-employed
The exact requirements can vary considerably from lender to lender.
This is another reason that simply asking whether a lender “does bank statement loans” doesn’t tell you very much.
There Isn’t Just One “Bank Statement Loan”
This is one of the most important things for borrowers—and even many real estate professionals—to understand.
A bank statement loan isn’t a single standardized mortgage product.
Through my company, I have access to more than 100 wholesale lending sources, and easily two dozen offer some form of bank statement financing.
Some use business bank statements.
Some use personal bank statements.
Some have separate programs for each.
And their guidelines can differ significantly.
Programs may differ in areas such as:
- Number of months of bank statements required
- Number of different business bank accounts that can be used
- Personal versus business statements
- Expense-factor calculations
- Allowance for NSFs (Insufficient Funds in Account-triggering a potential flag)
- Treatment of large or unusual deposits
- Business verification requirements
- Minimum credit requirements
- Reserve requirements
- Maximum loan amounts
- Down payment or equity requirements
- Property types
- Debt-to-income limits
- Length of self-employment required
Two lenders can review essentially the same borrower and reach very different qualifying results.
This is one area of mortgage lending where lender selection can matter almost as much as borrower qualification.
Who Might Benefit From a Bank Statement Loan?
Bank statement financing can be worth exploring for established self-employed borrowers whose tax returns don’t fully reflect the cash flow available to support a mortgage.
That could include:
- Small-business owners
- Independent contractors
- Consultants
- Real estate professionals
- Restaurant owners
- Contractors and tradespeople
- Medical, dental or legal professionals
- Owners of service businesses
- Entrepreneurs with substantial legitimate business deductions
A borrower doesn’t necessarily have a problem with their tax returns.
The tax returns may be completely accurate.
The issue is that taxable income and mortgage qualifying income aren’t always the same thing.
Does Non-QM Automatically Mean a Much Higher Rate?
No.
This is another misconception worth addressing.
Non-QM financing is sometimes described as though borrowers must automatically accept a dramatically higher interest rate in exchange for more flexible underwriting.
That isn’t necessarily the case.
Pricing depends on the loan program, credit profile, loan-to-value, property, loan amount, market conditions and numerous other factors.
In some situations, I’ve seen a Non-QM bank statement loan priced only about 1/8 of a percentage point in interest rate above a comparable Fannie Mae option for the same loan scenario (FICO Credit Scores, Loan to Value, Property Type, etc.) .
That doesn’t mean every borrower will see that small a difference. Depending on the circumstances, the pricing difference can be greater.
The important point is that “Non-QM” by itself doesn’t tell you what the rate will be.
You have to compare the actual programs available to that particular borrower.
What About Jumbo Loans and Reserves?
The comparison becomes even more interesting when the loan amount is above the applicable Fannie Mae and Freddie Mac conforming loan limits.
Jumbo financing has its own underwriting standards, and reserve requirements can be substantial depending on the lender, loan amount and borrower profile.
A Non-QM lender isn’t automatically more restrictive.
In fact, there are situations where a Non-QM bank statement program may require fewer reserves than a competing traditional jumbo program.
That can make a meaningful difference.
A borrower may have excellent cash flow and substantial assets but prefer not to maintain the level of post-closing reserves required by a particular jumbo lender.
Once again, the appropriate comparison isn’t simply:
Conventional = better. Non-QM = more expensive.
The real comparison involves the complete financing package:
Rate. Income calculation. Down payment. Reserves. Credit requirements. Documentation. Loan amount. Property. And the borrower’s overall financial objectives.
A Common Mistake: Waiting Until You’re in Contract
Self-employed borrowers should ideally evaluate their financing options before making an offer on a property.
Bank statement underwriting can uncover issues that aren’t obvious from simply looking at account balances.
A lender may question:
- Large or unusual deposits
- Transfers between accounts
- Declining deposits
- Significant fluctuations in business revenue
- Overdrafts or NSF (insufficient-funds activity)
- Commingling of business and personal funds
- Whether deposits actually represent business revenue
- Whether the proposed expense factor is appropriate for the business
- Whether the business and self-employment history can be adequately verified
The earlier these issues are identified, the more opportunity there is to determine which lender and program may be the best fit.
Why Shopping the Guidelines Matters
With conventional lending, borrowers often focus heavily on the interest rate.
With bank statement financing, the underwriting methodology may need to come first.
A lender offering a slightly lower rate doesn’t help if its income calculation prevents the borrower from qualifying.
Another lender might interpret the same bank statements differently, use a more appropriate expense factor, require fewer reserves or have business-verification requirements that better fit the borrower’s circumstances.
That’s one of the advantages of working with a mortgage broker who has access to multiple Non-QM lending sources.
The question isn’t simply:
“Who offers a bank statement loan?”
The better question is:
“Which bank statement program fits this borrower, this business and this property?”
San Francisco and Bay Area Borrowers
This can be particularly important in the San Francisco Bay Area.
Our market includes many entrepreneurs, consultants, real estate professionals, small-business owners and other self-employed borrowers whose financial situations don’t always fit neatly into conventional underwriting formulas.
At the same time, Bay Area property values frequently push borrowers into jumbo loan territory.
A borrower may have strong cash flow, substantial assets and a successful business but still have difficulty qualifying under a traditional tax-return analysis—or may find that the reserve requirements of a particular jumbo lender aren’t the best fit.
That doesn’t automatically mean the borrower can’t obtain attractive financing.
It may mean we need to look at the income—and the available lenders—differently.
The Broker’s Edge
Bank statement lending is a good example of why mortgage lending isn’t simply about finding the lowest advertised rate.
When numerous lenders offer different versions of the same general product, understanding the guidelines becomes critical.
Sometimes the solution is a personal bank statement program.
Sometimes it’s a business bank statement program.
Sometimes another Non-QM income-documentation method is better.
And sometimes, after reviewing everything, conventional or traditional jumbo financing still wins.
The objective is not to force the borrower into a particular loan category.
It’s to identify the financing structure that makes the most sense for the borrower’s actual circumstances.
Because sometimes the question isn’t whether a borrower earns enough money.
It’s how the lender is allowed to document it.
Coming Next — Lesson 6: DSCR Loans — When the Property’s Income Does the Qualifying
Bank statement loans offer an alternative way to document the income of a self-employed borrower.
But what if we’re financing an investment property and the borrower’s personal income isn’t the primary focus at all?
That’s where Debt Service Coverage Ratio—or DSCR—loans enter the picture.
Instead of qualifying primarily on the borrower’s W-2s, paystubs or tax-return income, a DSCR lender looks at the income generated by the investment property and compares it with the property’s required debt obligations under the lender’s guidelines.
In Lesson 6, we’ll explore:
- What a DSCR loan is
- How the Debt Service Coverage Ratio is calculated
- How rental income is determined
- What happens when the DSCR is below 1.00
- Purchase versus refinance transactions
- Long-term rentals versus short-term rentals
- Loan-to-value, reserves and credit requirements
- Why DSCR guidelines can vary significantly between lenders
- When DSCR financing may make more sense than conventional investment-property financing
For real estate investors, the question can change considerably.
Instead of asking:
“How much income does the borrower personally show?”
The more important question may become:
“Does the property generate enough income to support the loan?”
That’s where we’ll go next.
