Count Your Ownership Share On A Bank Statement — The Quick Read: Ownership percentage only matters on business bank statements, never on personal ones. Underwriters take a business account’s eligible deposits, apply an expense ratio, then multiply the net figure by the borrower’s ownership percentage before dividing by the number of statement months. Most wholesale bank statement programs draw the line at 25% ownership — below that, the business account generally can’t be used at all, no partial credit. A third-party document, not the borrower’s word, has to confirm the percentage before any of this math runs.
Key Takeaways
- Personal account deposits count at 100% with no ownership math applied. Business account deposits always run through both an expense ratio and an ownership percentage.
- A 25% ownership floor is the common convention across most wholesale bank statement programs, though a few set the bar higher.
- Ownership has to be verified by an operating agreement, K-1, or CPA letter — not just claimed on an application.
- Falling below the ownership floor typically shuts the business-statement door entirely, rather than prorating a smaller credit.
- Investors who can’t cleanly document a fractional ownership stake often find the subject property’s rent, not personal deposits, is the simpler path to qualify — that’s what a DSCR loan does instead.
The Setup: Why Ownership Percentage Even Enters the Picture
A bank statement loan replaces traditional personal-income documentation with 12 or 24 months of deposit history. That works cleanly for a sole proprietor with one business account. It gets complicated the moment two or more people share ownership of the entity generating those deposits.
Underwriters can’t hand a 40% partner credit for 100% of a shared account’s deposits. Someone else owns the other 60%, and that income belongs to them, not to the borrower alone. So the moment a business bank statement becomes the documentation source, ownership percentage becomes a required input in the qualifying-income formula — not an optional detail.
This issue shows up almost entirely on the personal-financing side. Think of a primary residence, a second home, or any purchase still underwritten on the borrower’s personal or business income — not on a rental property’s own rent. Picture two founders running an identical business with identical gross deposits. They can end up with very different loan amounts, purely because one owns 60% of the entity and the other owns 15%.
Key Terms Defined
Ownership percentage: the borrower’s documented share of a business entity, expressed as a percentage — the number that gets multiplied against net qualifying deposits.
Expense factor (or expense ratio): a fixed haircut applied to gross business deposits to estimate how much of that money is actual profit versus pass-through business expense, before ownership percentage is applied.
CPA letter: a signed statement from a certified public accountant or enrolled agent confirming a borrower’s ownership stake and, sometimes, an actual expense ratio in place of the fixed default.
Business-purpose loan: a loan made for an investment or business reason rather than to buy a home to live in — DSCR loans fall into this category and are reviewed differently from a standard owner-occupied mortgage.
Reserves: liquid funds a borrower must show, beyond the down payment and closing costs, to cover a set number of months of the housing payment.
The Mechanics, Step by Step
1. Confirm the account type first.
Personal account deposits qualify at 100%, with no expense factor and no ownership math applied at all — since these funds are already treated as fully belonging to the borrower. Business account deposits are the ones that trigger everything below. If a borrower’s income is entirely personal-account deposits — even from a business owner who simply pays themselves and deposits the check personally — ownership percentage never enters the calculation, since there’s no expense factor and no ownership haircut to apply in that scenario.
2. Get the ownership percentage documented by a third party.
An underwriter won’t accept a borrower’s stated ownership share on its own. Across the wholesale programs Lendmire’s team places files with, acceptable proof includes an operating agreement, a K-1 or Schedule G, or a CPA/tax-preparer letter confirming the actual percentage. Articles of incorporation or an active business license typically round out the file, confirming the entity itself is real and operating.
3. Check the ownership floor before doing any math.
Programs in the wholesale bank statement space commonly draw the self-employment line at 25% ownership, an approach that borrows its structure from agency underwriting conventions — Fannie Mae’s Selling Guide treats anyone with a 25% or greater stake as self-employed for income-documentation purposes. Non-QM lenders aren’t bound by that agency rule, but the same 25% convention shows up repeatedly as a practical cutoff. Under that threshold, the business account generally can’t be used as a qualifying-income source at all — it’s a hard gate, not a smaller prorated credit. Some programs set the bar even higher, requiring 50% ownership before a business account counts.
4. Apply the expense factor to gross deposits.
Across the network’s twelve- and twenty-four-month bank statement programs, the fixed expense ratio typically runs 20% for a service business with no employees, 40% for a business with one to five employees, and 50% for a business with six or more employees or any product-based business. An accountant-provided ratio can substitute for the fixed default, and a profit-and-loss method is available too, capped at 80%.
5. Multiply the net figure by ownership percentage, then divide by the statement months.
Gross deposits minus the expense factor equals net business income. That net figure gets multiplied by the borrower’s documented ownership percentage, then divided by 12 or 24, depending on the statement period used. The result is monthly qualifying income.
6. Transfers from the borrower’s own business count differently.
Say a borrower moves money from their business account into a personal account. Those transfer deposits count at 100% on the personal side. There’s no expense factor and no ownership haircut. Why? The money has already effectively gone to the individual.
Where This Goes Wrong
A minority ownership stake is the single most common derailment point on a co-owned bank statement file. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. That’s a different outcome than most borrowers expect walking in.
Unverified ownership is the second failure mode. A borrower who never formalized an operating agreement, never took a K-1, and can’t get a CPA letter turned around fast enough will stall a file with strong cash flow sitting right there in the statements, because the percentage itself can’t be confirmed by a third party.
Some deposit sources are ineligible no matter what the ownership math says. Day-trading proceeds, distributions from limited partnerships, and income tied to a small residential rental portfolio held in fewer than five units can all land in the same “ineligible” bucket regardless of how clean the ownership documentation looks.
And a P&L-based shortcut doesn’t skip the ownership step — it just moves it. Even where a CPA-prepared profit-and-loss statement replaces a full deposit review, the ownership percentage is still applied to the P&L’s net income figure before that number becomes qualifying income.
Who This Fits — And Who It Doesn’t
This math works cleanly for a majority owner — someone at 51% or higher — with a documented cap table, a business that generates consistent monthly deposits, and access to a CPA who can turn around a letter without delay. It also fits a sole owner with no partnership complexity at all, where the ownership question never really arises.
It fits less well for a minority partner in a multi-owner LLC, S-corp, or partnership who can’t clear whichever ownership floor a given program uses — commonly 25%, sometimes 50%. It also fits poorly for anyone whose only income evidence is passive or portfolio-source deposits that most programs treat as ineligible regardless of ownership percentage.
For high earners whose traditional personal-income documentation understate real income — founders, physicians, attorneys, and business owners who write off aggressively — the wholesale bank statement path Lendmire arranges through select programs runs from roughly $300,000 up through $30,000,000, split across a portfolio non-QM program that carries files to $6,000,000 and a separate bank portfolio ladder that carries twelve-month-statement files to $30,000,000 on its own leverage bands — 65% loan-to-value to $5,000,000, 60% to $10,000,000, and 55% up to $30,000,000. Leverage on a primary residence steps down as the loan size climbs — well above 80% on smaller balances, tightening through the mid-single-digit millions, then moving to case-by-case underwriting above $4,000,000. Credit floors sit around 660 on the portfolio program and climb to 700 above the program’s super-jumbo threshold. Debt-to-income can run as high as 50%, and reserve requirements scale with loan size — 3 months on smaller balances, 6 months into the mid range, and 9 months above that. None of these figures are guaranteed for any individual file; every parameter here reflects select wholesale-program guidelines, subject to full underwriting.
When the Rental Property Itself Solves the Problem
An investor who owns a rental property with partners — and can’t cleanly document a fractional ownership share of the business account tied to that partnership — often finds a much simpler path by financing the property itself rather than their personal income. DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
A DSCR loan mainly looks at one thing: does the property’s rental income cover the payment? This is subject to lender guidelines. Lenders don’t check the borrower’s personal or business bank deposits. They also don’t calculate any ownership percentage of a business. Instead, they compare the property’s rent against its monthly payment. That ratio drives approval — not who owns what share of a LLC’s operating account. A ratio of 1.00x means rent and payment roughly break even. On many files, that 1.00x figure is a select-program floor, not a universal standard. Some lenders in the network will accept ratios below that, though they’ll generally adjust the leverage and terms.
This is worth thinking through carefully if you’re an investor building a portfolio with co-owners. Trying to document a 20% or 30% stake in a partnership’s operating account for a bank statement loan on a different property can cause a lot of friction. It’s often simpler to just finance the rental property itself, based on its own rent coverage. Lendmire’s complete DSCR loans guide explains how that property-level qualification actually works. It’s a useful comparison to the ownership-percentage mechanics covered here. Are you weighing both paths at once — say, a bank statement refinance on a primary residence and a DSCR purchase on an investment property? You can also read how payroll deposits into a personal account count toward qualifying income. That mechanic works independently of the ownership-percentage question.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
This article is for general information only. It isn’t legal or tax advice. If you’re weighing ownership documentation, entity structure, or how a business interest affects loan qualification, talk to a qualified attorney or CPA about your own situation before acting.

Frequently Asked Questions
Does having signing authority on a business account mean I can use its deposits?
No. Account access and legal ownership are two different things. Underwriters tie eligibility to a documented ownership percentage confirmed by a third party — an operating agreement, K-1, or CPA letter — not to who can move money in and out of the account day to day.
What if my ownership percentage isn’t written down anywhere yet?
That’s a common stall point. Without a formal operating agreement, K-1, or CPA letter confirming the exact percentage, an underwriter has nothing to apply the formula to, even if the deposit history looks strong. Getting that documentation formalized before submitting the file usually prevents a mid-process delay.
Can I get partial credit if I own less than 25% of the business?
Generally no. Most wholesale bank statement programs treat sub-threshold ownership as disqualifying for the business-statement path entirely, not as a smaller, prorated credit. A few programs set the floor even higher, at 50%.
Does this ownership math apply to a DSCR loan on a rental property?
No. DSCR lender review runs on the subject property’s rent-to-payment coverage, not on the borrower’s personal or business bank deposits, so the ownership-percentage-of-a-business question generally doesn’t come up on that product at all.
Do transfers from my own business into my personal account get the ownership haircut too?
No. Transfers from a borrower’s own business into their personal account are treated as personal deposits and typically count at 100%, without an expense factor or ownership percentage applied.
