A bank statement loan with business partners counts only the borrower's share of the business account. The lender works out income from the account's qualifying deposits after the expense factor, then multiplies by the borrower's ownership percentage. Partners who are not on the loan may sign a letter about the account, and some programs set a minimum ownership share.
How does a bank statement loan with business partners prorate deposits?
Proration means multiplying the business's income by the borrower's ownership share, so a 50 percent owner is credited with half. On a bank statement loan, the lender first builds the business income from deposits, then prorates it. The order matters: exclusions and the expense factor apply to the whole account before the share is taken.
The reason is simple. The deposits belong to the business, and the business belongs to more than one person. If the borrower were credited with all of it, a two-owner company could qualify two borrowers for the full income at once.
The sequence
- Total the business account's deposits over the lookback.
- Remove transfers, loans, capital contributions and one-time credits.
- Apply the lender's expense factor to the qualifying deposits.
- Multiply what is left by the borrower's ownership percentage.
- Divide by the number of months for monthly income.
Capital contributions from partners
Money that a partner puts into the business is not revenue. It shows up on the statements as a deposit, often a round number with the partner's name in the description. It comes out with the other exclusions. A business that relies on partner contributions to cover payroll is a different risk from one funded by its customers, and an underwriter will notice.
Proving a partner's ownership share to the lender
A lender proves ownership share from documents that name the owners and their percentages. The usual ones are the operating agreement for an LLC, the partnership agreement, a CPA letter, or the business's tax filings, such as the K-1 each owner receives. The percentage on these documents is the one the lender uses to prorate.
Why the threshold matters
Many programs set a minimum share before a borrower can use business deposits as their own income. For agency loans, Fannie Mae's self-employed borrower guidance treats anyone with a 25 percent or greater ownership interest as self-employed. Bank statement programs set their own floors, which may differ. A borrower below the floor may need to qualify another way, such as from the draws or wages paid to them.
When the documents disagree
An operating agreement may say 50/50 while the K-1s show a different split of profits. A business may have changed owners since the last filing. Lenders use the most recent document they trust and ask for an explanation when two sources differ. Resolve the conflict before submission. A CPA letter stating the current split, with the date it took effect, is often the cleanest answer.
Ownership that changed during the lookback
A split that changed partway through the lookback raises a harder question. Suppose the borrower owned 30 percent for the first eight months and 60 percent for the last four. Some lenders prorate each month at the share that applied then. Others use the current share only if it has held for a set time. Either way, the borrower needs a dated document showing when the change happened, such as an amended operating agreement or a signed buyout.
Partner access letters on a shared business account
A partner access letter is a signed statement from the other owners that the borrower may use the business account's funds, or that taking funds will not harm the business. Programs commonly ask for one when business money is used for the down payment, closing costs or reserves, and some ask whenever a shared account is used for income.
What the letter usually says
- The business name and the account being used.
- The names and ownership shares of every owner.
- That the other owners know of the loan and consent to the borrower's use of the account for this purpose.
- If funds will leave the account, that the withdrawal will not hurt the business's operations.
- Signatures and dates from each non-borrowing owner.
Lenders word their own templates. Ask for the lender's form before the borrower drafts one.
When a partner will not sign
A partner may refuse because they do not want their name near someone else's mortgage. Without a letter, the lender may still accept the prorated income but refuse to count business funds toward reserves. Or the lender may decline the business account entirely. Find out early. A broker who learns of a reluctant partner at closing has few good options.
A 60/40 partnership's prorated deposit income
A worked example shows how proration splits the same account between two owners. The business below is a fictional two-owner contracting firm with one business checking account. Every figure is invented for illustration, and the 50 percent expense factor is an example, not any lender's rate.
Over 12 months, the account received $512,000 in credits. Of that, $20,000 was a capital contribution from the minority owner and $12,000 was an equipment loan funding. Qualifying deposits were $480,000.
| Line | Example: 60% owner | Example: 40% owner |
|---|---|---|
| Business qualifying deposits, 12 months | $480,000 | $480,000 |
| After 50% expense factor | $240,000 | $240,000 |
| Ownership share | 60% | 40% |
| Annual income credited | $144,000 | $96,000 |
| Monthly income | $12,000 | $8,000 |
Each owner can qualify on their own share. Neither can claim the $240,000. If both applied for mortgages at the same time, their credited incomes together would equal the business's estimated income, which is the point of the method.
The expense factor applies to the whole firm
The expense factor reflects the business's costs, so it applies before the split. Applying it after makes no arithmetic difference in this example, but it matters when a lender accepts a CPA expense ratio for the business as a whole. How the bank statement loan expense factor is set covers fixed factors and CPA letters.
Deposits versus profit
Proration on deposits still estimates income. It does not show how the owners actually split money. If the partnership pays the 60 percent owner a salary and leaves profits in the business, the deposit method and the owner's personal statements will tell different stories. Estimating net income from bank statements explains how deposits and debits combine into a profit estimate.
Can only one business partner apply?
Yes. One business partner can apply for a bank statement loan alone, and that is the usual case. The other owners do not join the loan, sign the note or share the debt. Their role is limited to proving ownership and, where the lender asks, signing an access letter. The borrower qualifies on their own share of the business income.
What the non-borrowing partners give
- Confirmation of the ownership split, often through the operating agreement or a CPA letter.
- An access or consent letter, when the lender's program calls for one.
- Nothing about their own credit, income or assets, in most programs.
Business debts shared among owners
A business loan that appears on the borrower's personal credit report, because they guaranteed it, may count against their DTI in full. The lender may accept proof that the business pays it. With partners, the proof needs to show the business, not the borrower personally, has been making the payments.
Will the business keep going?
A lender's question about any business is whether its income will continue. A partnership adds a question about the partners. If the other owner is leaving, a buyout is pending or the agreement allows one partner to dissolve the firm on short notice, the income may not last. Bank statement loan income continuance covers how lenders judge whether a business will keep paying its owners.
When partner draws beat prorated business deposits
Partner draws are payments from the business account into the owner's personal account. Reading the personal account instead of prorating the business one is often better when the partners take regular draws, when ownership is below the lender's floor, or when the business account is hard to read. Draws are already the borrower's share, so no proration or factor applies.
Signs the personal account is the better read
- The borrower receives a steady draw or salary from the business each month.
- The business account has large pass-through amounts, such as client deposits held for subcontractors.
- The partners do not want the business statements in someone else's loan file.
- The borrower's share is small, and the prorated income would be low in any case.
The trade-off
Draws reflect what the borrower takes, which may be less than their share of the business's income. A partnership that reinvests profits pays its owners less than it earns. In that case prorating the business account gives the higher figure, if the lender accepts it. Run both numbers and pick the one the borrower can document.
Collect it at intake
Ownership splits, partner names and access letters are easy to gather at the start and painful to chase later. A business lender's small business loan intake process shows the kind of upfront checklist that prevents the chase. TrueBankFlow labels matching amounts that move between a business account and a personal one as transfers, so a broker can see the draws and decide which account carries the income.
