How To Use A Bank Statement Loan On Commission Income

The Quick Read: A bank statement loan lets a commission earner qualify on deposit history instead of traditional personal-income documentation, which matters because commission income often looks smaller on paper than it does in the bank. The lender averages 12 or 24 months of deposits, applies an expense factor if the money lands in a business account, and builds a qualifying income number from what’s left. For a rental purchase, the same borrower may skip this path entirely and qualify on the property’s rent instead.

Key Terms Defined

Bank statement loan — A non-QM mortgage that verifies income through 12 or 24 months of bank deposits rather than W-2s or tax transcripts.

Expense factor — A percentage deducted from business account deposits before the remainder counts as qualifying income, meant to account for the cost of running the business.

DSCR (debt service coverage ratio) — A measure of whether a rental property’s income covers its own housing payment, used on business-purpose investment loans instead of personal income.

Business-purpose loan — A loan made to buy, refinance, or improve a non-owner-occupied rental property, which sits outside the consumer repayment-capacity rule entirely.

Repayment-capacity/qualified-mortgage — The federal rule requiring a lender to verify a borrower can repay a loan using reliable income or asset records before making a consumer mortgage.

The Setup: Why Commission Income Needs Its Own Path

Commission earners face a documentation problem that salaried workers don’t. A real estate agent, insurance producer, or outside sales rep can move a large amount of money through their accounts each year, while showing a much smaller number on their tax return. That’s because commission-based businesses carry real deductible costs — marketing, mileage, licensing fees, and split payments to a brokerage.

A tax-return-based mortgage measures net income after every one of those deductions. A bank statement loan measures what actually lands in the account, averaged over time. For a commission earner whose write-offs are legitimate but heavy, that gap can decide whether a purchase or refinance goes through.

The federal consumer-finance regulator’s repayment-capacity and Qualified Mortgage rule requires lenders to verify a borrower’s income using reasonably reliable records when making a consumer mortgage. Tax transcripts are one accepted method, but not the only one. Bank statement programs exist because non-QM lenders can build that verification around deposit history and expense documentation instead. The lender’s underlying determination still has to be made in good faith. The full regulatory text lists several acceptable verification methods. Deposit analysis fits within that framework — it’s not working around it.

The Mechanics, Step by Step

The process runs in a fixed order, and skipping a step is usually what causes a file to fall apart later.

Step 1 — Pick the documentation window. Most programs in Lendmire’s wholesale network ask for 12 or 24 consecutive months of statements, though the strongest bank-portfolio ladder in this guideline set runs strictly on 12 months. Underwriters review every statement page by page, looking for a consistent deposit pattern rather than a single strong month.

Step 2 — Route the deposits correctly. Where commission money lands changes the math. Deposits into a business account typically get reduced by an expense factor before they count — 20% for a service business with no employees, 40% for a business with one to five employees, or 50% for a business with six or more employees or any product-based business, in the guidelines this article works from. Deposits into a personal account are generally averaged more directly, without that same deduction, because a personal account isn’t presumed to carry the same operating overhead. Transfers from the borrower’s own business into a personal account count in full.

Step 3 — Strip out anything that isn’t recurring income. Loan proceeds, one-time transfers, and unusual lump deposits get excluded before the average is calculated. The goal is a repeatable number, not gross account activity.

Step 4 — Bring in a CPA letter or P&L if it helps. A licensed tax preparer can certify the business’s actual expense ratio in writing. Where the program allows it, that certified ratio can replace the default factor — sometimes producing a stronger qualifying-income number than the flat percentage would. Some programs also accept a preparer-signed profit-and-loss statement as a supporting or alternate path alongside statements, with that path capped under the program’s guideline at an 80% qualifying-income allowance under the P&L method.

Step 5 — Reserves and debt-to-income get checked separately. The qualifying income figure feeds into a standard debt-to-income calculation, capped at 50% in most files this article’s guidelines cover, while reserves are evaluated on their own track — typically three months of payments on smaller loan amounts, stepping up to six and then nine months as the loan size grows, plus additional months per financed rental property.

Step 6 — The trend test. Underwriters run the trailing three- and six-month deposit trend against the full 12- or 24-month period to see if income is rising, flat, or falling. A commission earner whose recent months are trending up gets treated very differently from one whose recent months are sliding, even when the long-run average looks identical.

Documentation completeness matters as much as the income level itself. In one securitized non-QM pool, a loan was flagged specifically because the file was qualified on a 12-month business bank statement program but was missing a required month — the statement set wasn’t actually 12 consecutive months, and that gap, not the borrower’s income, was the defect that surfaced. A missing month is a mechanical failure, not a judgment call, and it’s worth double-checking before a file goes to underwriting.

Personal Account or Business Account? The Choice Isn’t Neutral

Where commission deposits land can change the qualifying income number, sometimes by a meaningful margin. Money in a business account is generally assumed to carry operating costs, so an expense factor comes off the top before the rest counts. Money in a personal account isn’t assumed to carry that same overhead, so it’s often averaged more directly. That difference is set by the individual program’s guidelines, not by a uniform industry rule, and it’s one of the first things worth asking about before choosing which account a commission check should hit.

W-2 Commission vs. 1099 Commission: Not the Same File

A commission earner who receives a W-2 and one who works as a true 1099 contractor face different tax dynamics — and that difference has gotten sharper in recent years. The Tax Cuts and Jobs Act eliminated unreimbursed employee business expense deductions for most W-2 workers under IRC Section 67(a) and 67(h), for tax years beginning after 2017. In practice, a W-2 commission employee’s reported wages are no longer suppressed by a personal deduction for mileage, tools, or client entertainment the way they were before that change.

That means the “tax return understates cash flow” problem is now concentrated much more heavily in true 1099 and Schedule C commission earners, who can still deduct ordinary business expenses. A W-2 commission employee whose pay stubs already reflect close to their real earning power may not need a bank statement path at all — pay stubs and W-2s might solve the problem more directly. A 1099 commission earner whose Schedule C shows a fraction of their deposit activity is usually the stronger candidate for deposit-based qualification.

Multiple commission sources add friction either way. A borrower drawing commissions from several different payers has more moving parts for an underwriter to reconcile, since each stream’s continuation and consistency needs separate support in the deposit history.

The Business-Purpose Fork: When DSCR Replaces the Question Entirely

Here’s what most commission earners who also invest in rental property miss. Say a loan is genuinely for business — buying, refinancing, or improving a non-owner-occupied rental. In that case, it can skip the consumer income-verification rules entirely. Reg Z has a business-purpose exemption. It says an extension of credit made mainly for a business, commercial, or agricultural purpose doesn’t need to follow the consumer Ability-to-Repay rule. A non-owner-occupied rental counts as a business purpose, even if it’s just a single unit.

That’s why a DSCR loan can work differently: it qualifies mainly on the property’s own rent covering its payment — subject to lender guidelines — instead of running the borrower’s commission income through deposit analysis at all. For an investor who is both a commission earner and a landlord, the practical move is often to plan financing in steps: use a bank statement program for the owner-occupied purchase, and let rental purchases run on DSCR math instead. Lendmire’s DSCR loan versus bank statement loan comparison walks through that choice in more depth. The complete DSCR loans guide covers how property-income qualification works from start to finish. Commission earners with other non-traditional income streams sometimes face a similar documentation choice. Lendmire’s coverage of using K-1 income on a super-jumbo file is a useful comparison for borrowers weighing more than one alternative-income path at once.

What Can Go Wrong

Bank statement lending on commission income isn’t a shortcut, and treating it like one is where files stall.

Non-QM doesn’t mean no underwriting. It means the loan doesn’t meet Qualified Mortgage standards — the deposit-analysis process itself is granular, month by month, and a borrower who assumes “alternative documentation” means “less scrutiny” is usually surprised by how detailed the review gets.

Account routing can cut both ways. Treating gross business deposits as pure profit overstates income; applying a flat expense factor without ever exploring a CPA-certified alternative can understate it. Both mistakes are avoidable, but only if the borrower knows to ask.

The two-year history convention is common but not universal. It’s a lender guideline, not a statute, and different non-QM programs set their own seasoning requirements — which is part of why a bank statement path exists as an alternative in the first place.

A missing statement is a real defect. As the securitized-pool example above shows, an incomplete 12- or 24-month set — not a weak income level — is enough to sink a file on documentation grounds alone.

Loan Sizes and Leverage: What the Range Looks Like

Loan amounts on the bank statement path used for this article’s guideline set run from $300,000 to $30,000,000 across two separate wholesale programs — a portfolio non-QM bank-statement program carrying files to $6,000,000, and a bank portfolio program that carries 12-month-statement files as high as $30,000,000 on its own ladder: 65% loan-to-value to $5,000,000, 60% to $10,000,000, and 55% up to $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower.

Leverage on a primary residence steps down as the loan amount grows: roughly 90% at $300,000 to $1,000,000, 85% up to $1,500,000-$2,000,000, 80% into the $2,000,000-$3,000,000 range, and 75% at the top credit tier up to $3,500,000-$4,000,000, with everything above $4,000,000 reviewed case by case before submission rather than quoted as a flat ceiling. Second homes and investment properties generally run about five points lower at every size band, since they carry more risk than an owner-occupied purchase.

Credit floors run at 660 on the portfolio program and step up to 700 above the super-jumbo line — $3,500,000 on a primary residence, $3,000,000 on a second home or investment property. Reserve requirements scale with size too: three months of payments to $500,000, six months to $1,500,000, and nine months above that, with additional months required per financed rental property. Cash-out is capped at $1,500,000 in proceeds above 60% loan-to-value on the portfolio program. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

The strongest files under this article’s guidelines pair a clean 12- or 24-month deposit trend with a CPA-certified expense ratio, plus reserves that clear the required minimum with room to spare. A commission earner whose income is flat or rising tends to have a much easier path through underwriting than one whose recent months are down, even slightly.

Who This Fits and Who It Doesn’t

A bank statement loan tends to fit a commission earner whose traditional income documents understate their real cash flow, because of legitimate business deductions. It also fits best when deposits are steady or growing, and income lands mostly in one or two accounts that are easy to trace. It fits especially well for a 1099 or Schedule C commission earner, since that’s exactly where the Tax Cuts and Jobs Act widened the gap between reported income and actual deposits.

It fits less well for a W-2 commission employee whose pay stubs already reflect close to their real income, since a traditional documentation path may qualify them just as easily with less paperwork. It also fits less well for someone whose commission income just started, whose deposits are trending downward, or whose statement history has gaps — all three are exactly the weak points underwriters test for.

For the same borrower buying a rental property rather than a home to live in, the more direct path is often the property’s own income rather than personal deposit history at all — which is the DSCR fork described above.
