Bank Statement Loan With a Business Partner: What Counts?
The question people search but rarely ask out loud
“I own half the business with a partner. Do they have to sign anything or show their credit, and will the lender count all the deposits or just my half?”
Bank Statement Loan With a Business Partner: What Counts, and Does Your Partner Have to Know?
Half the business is yours, and every deposit lands in an account you share with someone else. That raises questions most owners never say out loud: does my partner have to sign, will they see my finances, and does the lender count all of it or only my half? Here are straight answers.

What you usually hear, and the honest answer
This question usually comes up late in a first call, after the easy stuff. A business owner has been explaining their deposits, and then they pause. The account is not only theirs. A partner, a sibling, an old college roommate or a spouse owns part of it. Suddenly the worry is less about the loan and more about the relationship. Will my partner have to get involved? Will they see my credit? Will the lender take half my income away because the business is shared?
Those are fair worries, and they have practical answers. A shared business does not make a shared mortgage. It does mean the file has to show who owns what, how the money moves, and which part of the business income belongs to you. Get those three things clear and the rest is ordinary underwriting.
Your Partner Is Not Your Co Borrower
Start with the part that matters most to the relationship. Owning a company together is not the same as borrowing together. Your business partner does not sign your note, does not go on title to your home, and does not have their credit pulled for your loan simply because they co own the business with you. The only people on a mortgage are the people applying for it.
What a lender does care about is the business itself, because the business is where your income comes from. If you share an account, the statements will show the whole company's money, not only yours. That is normal. The job is to translate those statements into the part that is fairly yours, and to document that you have the right to use them in your file.
The IRS has a simple way of describing this kind of company. Its partnership page says "A partnership is the relationship between two or more people to do trade or business." The partnership files an information return on Form 1065, does not pay income tax itself, and passes profits or losses through to each partner on a Schedule K1. S corporations work in a similar pass through way, filing Form 1120S and sending each shareholder a K1. That paper trail is useful, because it already states your share.
How Your Share Shows Up in the File
Different business setups leave different documents behind. Here is how the common ones compare, and what each tends to mean on a bank statement loan versus a full doc conventional loan. Program details on our side are confirmed per file.
| How the business is set up | What the IRS sees | Bank statement loan (our program) | Conventional (Fannie Mae standard) |
|---|---|---|---|
| Partnership or multi member LLC taxed as a partnership | Form 1065; each owner gets a Schedule K1 | Business deposits over a set number of months, an expense factor of 10% to 50% by industry and CPA, and your ownership share documented | Personal and business returns, usually two years, read through Form 1084; 25% or more ownership counts as self employed |
| S corporation with two or more shareholders | Form 1120S; each shareholder gets a K1, often plus W2 wages | Same deposit based read, with your share and any W2 wages reviewed per file | Returns and K1 through Form 1084, plus wages |
| Spouses who own the business together | Depends on how the business files; ask your CPA | Both spouses can apply together or one can apply alone; ownership share still documented | Same two year return standard for each owner who is self employed |
| You own less than 25% | Usually a K1 for your share | Reviewed per file; tell us your share on the first call | Under 25% is not treated as self employed in Fannie Mae's guide |
Notice the theme. Every row comes back to one number: your percentage. If you are not sure of it, or if the operating agreement and the tax returns say different things, fix that first. A lender cannot guess at ownership, and your CPA or attorney is the right person to make sure the documents match reality.

Worked Example: Two Partners, One Scottsdale Design Firm
Example numbers, not market data and not a quote. Two partners each own 50% of an interior design firm in Scottsdale. All revenue lands in one business checking account. One partner wants to buy a $600,000 home with 20% down. If you are shopping in the same area, our page on financing a home in Scottsdale has local detail.
| Line | Example figure | What it means |
|---|---|---|
| Average monthly business deposits | $40,000 | Money into the shared account, after removing transfers between the owners' own accounts |
| Expense factor | 40% | Inside our 10% to 50% range; the real figure depends on industry and CPA |
| Business income after the factor | $24,000 a month | $40,000 less 40% |
| Applicant's ownership share | 50% | From the operating agreement and K1 |
| Example income for the applicant | $12,000 a month | Illustrative only; the exact method is confirmed on the file |
| Example loan and payment | $480,000 at an example 8.18% | About $3,582 a month principal and interest over 30 years |
The example rate is one point above the Freddie Mac survey's 30 year fixed average of 7.18% for the week of November 5, 2026. That survey figure is a benchmark only, not a Pillar Mortgage Group rate. The point is the shape of the math, not the rate.
Now the conventional side of the same firm. Say the applicant's K1 shows $90,000 of ordinary income for the year after the firm's legitimate deductions, which works out to $7,500 a month before any other adjustments Form 1084 makes. Same business, same partner, two very different income pictures. Neither is wrong. One reads the deposits; the other reads the return after the write offs your CPA took because they were real business costs.
This is where Blake's recurring question comes back: do the tax savings from those deductions outweigh the extra interest on a bank statement loan? For partners the answer is personal, because each partner's tax picture is different even inside the same company. Run your own figures in the calculator below, then take the result to your CPA.

2. Tax savings vs the extra cost of the loan
At these numbers, your tax savings exceed the extra interest by $11,931 a year.

Illustrative only. Not tax advice, not a quote, not an approval and not a commitment to lend. Default values are placeholders, not Pillar Mortgage Group rates or terms; enter the rates you were actually quoted. Step 1 divides your taxable net income by 12 and your deposits after the expense factor by 12; real underwriting averages your history and lenders set the expense factor (10% to 50% at Pillar Mortgage Group, depending on industry and your CPA). Step 2 compares the interest paid on a 30 year fixed at each rate over the years you enter and ignores points, fees, down payment and reserve differences. Only legitimate deductions your CPA supports belong in this math. Talk to your CPA about taxes and to us about the loan.

What Most Lenders Won't Tell You
Transfers between owners can look like income, and they are not. If you and your partner move money between the business account and your personal accounts, those transfers have to be separated from real customer deposits. Label them before anyone asks. It keeps the income honest and saves a round of questions.
Business debts can follow you even when your partner's credit does not. Fannie Mae's guide makes the point plainly for conventional loans: when a business owner's income is not being used, the business debts can still land in the debt to income math. Know what loans, leases and cards are in your name personally before we run numbers.
Your partner may hear about it, even if they never sign. If a file needs a short letter about the shared account, or a copy of the operating agreement, someone in the business may need to provide it. Most owners would rather have that conversation on their own terms, early, than get surprised by a document request in week two.
A partnership dispute is an underwriting problem. If ownership is being renegotiated, a buyout is pending or a partner is leaving, the numbers can change mid file. Tell us. We would rather wait a month than build a loan on a share that is about to move.
The cheapest path is sometimes the full doc loan. If your K1 already supports the payment, a conventional loan may cost less over time. We price both and say so when full doc wins.
Who This Is Not For
A bank statement loan is not the right fit if your returns already qualify you comfortably, if you own a small slice of the company and draw a W2 wage that tells the whole story, or if ownership is in the middle of changing hands. It is also never a reason to move money around to make deposits look bigger. Deposits should reflect real business revenue. If anything about your filing or ownership feels unclear, talk to your CPA or attorney before you apply.
Conversations to Have With Your Partner and Your CPA First
Owners who move fastest through a file do a little homework with the two people closest to the business.
With your partner: agree on how you will handle any request for account information, decide who keeps the statements, and confirm that the operating agreement on file is the current one. You do not need to share your personal credit, your purchase price or your loan terms. You only need to agree on the business side.
With your CPA: confirm your ownership share as it appears on the returns, ask what expense ratio fits your industry and your company, and ask whether owner distributions, draws and transfers are recorded cleanly. A CPA who understands the plan can also tell you how the tax picture compares across a bank statement loan and a full doc loan. That comparison is theirs to make. Our part is showing what each picture does to the loan.
With yourself: decide how long you expect to keep the home and the loan. Partners often have exit plans for the business that affect the house too. A buyout, a sale of the firm or a new partner can all change the income a lender would see later.
Keeping a Shared Account Clean
The easiest bank statement files from partnerships share a few habits. Customer revenue goes into one business account. Owner draws go out on a regular rhythm and are labeled. Personal spending stays in personal accounts. Large one time deposits, such as a loan from a partner or an equipment sale, come with a short note. None of this is complicated, and all of it helps an underwriter see the true business.
If the account is messy today, do not panic and do not rush to rearrange it right before applying. Changes that appear suddenly can raise more questions than they answer. Instead, tell us what the account looks like, and we will tell you which months read cleanly and what explanation the rest will need. Our average close runs about 18 days, as fast as 10 when the file is ready.

Frequently asked questions
Does my business partner have to sign my mortgage?
No. Owning a business together does not make your partner a borrower on your home loan. Only the people applying for the mortgage sign the note. Some files ask a co owner for a short letter or document about the shared business account, and we tell you up front if yours does.
Will the lender count all the deposits or only my share?
The income that counts is tied to your ownership share of the business, documented by your operating agreement and returns, with the exact method confirmed on your file. Transfers between owners are separated from real business revenue.
Will my partner's credit affect my bank statement loan?
Your partner's personal credit is not pulled for your loan just because you co own the business. Business debts that are in your own name can still count in your debt to income, so tell us about them early.
Can I get a bank statement loan if I own less than 25% of the business?
Under 25% is not treated as self employed in Fannie Mae's guide, which usually means your income is documented a different way, such as wages or a K1. Tell us your share on the first call and we will show which path fits.
Can my spouse and I use our jointly owned business to qualify?
Yes, you can apply together or one of you can apply alone. Either way the ownership share is documented. Talk to your CPA about how the business files; this is not tax advice.
Is a bank statement loan cheaper than a conventional loan for partners?
It depends on the numbers. A bank statement loan usually costs more in interest, while your legitimate deductions may lower your taxes. Compare both with the calculator, then review the result with your CPA.
