Two clients both describe themselves as “self-employed.” One is a management consultant who invoices a handful of corporate clients and receives 1099s each January. The other owns a medical spa with six employees, a commercial lease, and monthly payroll. Both can be excellent candidates for a bank statement loan — but the underwriting path for each looks meaningfully different, and treating them the same way is one of the more common mistakes that slows these files down.
The Problem: “Self-Employed” Isn’t One Category
A 1099 contractor’s bank deposits are usually a reasonably clean proxy for income — client payments come in, personal or minimal business expenses go out, and there’s little noise in the account. A business owner’s bank statements tell a much messier story: gross revenue deposits sit alongside payroll runs, vendor payments, rent, inventory purchases, and owner draws, all mixed into the same account or spread across several. Applying a single expense factor to both without understanding the difference either overstates the contractor’s qualifying income or understates the business owner’s — and either mistake creates problems later in underwriting.
The Solution: Match the Documentation Path to the Business Structure
For a 1099 contractor with no employees and minimal overhead, many bank statement loan programs will use personal bank statements and apply a lighter expense factor — sometimes as low as 10–15% — since there’s little business expense to account for. For a business owner running a company with real operating costs, lenders typically require business bank statements and apply a standard expense factor, often a flat 50%, to back into a realistic net income figure after accounting for the cost of running the business. Some programs allow a business owner to use a CPA-prepared profit-and-loss statement alongside bank statements to support a lower expense factor than the default, if the business genuinely runs leaner than 50% overhead.
Ownership percentage matters too — a borrower who owns 100% of the business can use its full deposit history, while a borrower who owns 50% of a partnership typically has their qualifying income calculated on a pro-rata basis, reflecting only their share of the business’s cash flow.
What This Looks Like in Practice
The management consultant deposits an average of $42,000 a month into a personal account with almost no business expense running through it. Using a 15% expense factor, that produces roughly $35,700 in monthly qualifying income — a figure close to the account’s actual deposits, since there’s little overhead to discount. The medical spa owner deposits an average of $210,000 a month in gross business revenue, but with six employees, a commercial lease, and supply costs, a standard 50% expense factor produces $105,000 in monthly qualifying income — a more conservative number, but one that still dramatically outperforms what her tax returns show after equipment depreciation and other deductions. Applying the medical spa’s 50% factor to the consultant’s account would have understated his qualifying income by more than $5,000 a month; applying the consultant’s 15% factor to the spa owner’s account would have wildly overstated hers.
Why This Matters for Advisors
When a client’s business structure and expense profile are understood upfront, the pre-qualification number a client hears in the first conversation is far more likely to hold up through underwriting — which matters enormously once they’re in a competitive offer situation. It also affects which lender is the right fit, since not every bank statement loan program handles complex, multi-owner, or high-overhead businesses the same way.
If you have a self-employed client planning a purchase or refinance, it’s worth understanding whether they function more like a contractor or a business owner before setting expectations on qualifying income. I’m happy to walk through the numbers on any client’s specific structure.
