How a Bank Statement Loan Reads K-1 Partnership Deposits at 50%

The Quick Read: A bank statement loan reads partnership money from the deposits that land in your accounts, not from the K-1 itself, and a 50% expense factor means half of eligible business deposits are set aside as presumed operating cost before the rest counts as income. The K-1 mostly proves you own a piece of the partnership. Your ownership share and the account type then shape the final number.

• The K-1 is a tax allocation. It does not record cash you received.
• A 50% factor is a commonly cited example, not a universal rule. Each lender program sets its own.
• Personal-account deposits generally skip the factor. Business-account deposits take it.
• Ownership percentage can shrink business deposits further.
• Transfers, loan proceeds, refunds and one-time credits come out before any averaging.

A K-1 partner often has a tax return that understates cash flow. Depreciation and write-offs pull Box 1 down while the account fills up. Bank statement underwriting exists for that gap. This piece walks through how the file is actually read, step by step, and where it breaks.

One point on wording. “At 50%” usually means a 50% expense factor. It can also mean a 50% ownership stake, which is a separate multiplier. This article uses the first meaning and treats ownership share on its own.

Key Terms Defined

K-1 (Schedule K-1): The tax form that reports a partner’s share of the partnership’s income, loss and other items.

Distribution: Cash or property the partnership actually pays out to a partner.

Guaranteed payment: A salary-like payment to a partner for services, reported apart from ordinary income.

Expense factor: The percentage of business deposits a lender removes to estimate operating costs.

Eligible deposit: A deposit that counts as real business revenue after transfers, loan proceeds, gifts and one-time credits are stripped.

Ownership share: The percentage of the business that you own, proven by the operating or partnership agreement and the K-1.

Why Does the K-1 Say One Thing and the Bank Account Another?

The K-1 reports allocated taxable income. The bank account shows cash. Those are different events, and a deposit-based loan reads the cash.

Per the IRS Partner’s Instructions for Schedule K-1, Box 1 is the partner’s share of ordinary income or loss from the partnership’s trade or business. Distributions, such as cash paid to the partner, are reported separately in Box 19. A partner can owe tax on income the partnership kept inside the entity. A partner can also receive large distributions while Box 1 shows little.

That is why a tax-return program and a deposit program can give the same borrower very different incomes. A return-based read picks up depreciation and write-offs, and a loss in one entity can drag down the total. A deposit read largely bypasses those items and looks at what came in.

On a bank statement file, the K-1 still matters. It and the partnership or operating agreement show that you own the business whose deposits are being counted. They do not set the income.

What Does the Lender Actually Read?

The lender reads 12 months of statements, either personal or business, and keeps only deposits that look like real revenue. Across the wholesale network, qualifying income comes from deposit averages with lender-specific expense factors. No program promises a universal formula.

The statement period varies by program. Market commentary describes self-employed borrowers supplying 12 to 24 months of statements, and Scotsman Guide gives a 50% expense factor as an example. Select lenders in Lendmire’s network start at 12 months.

Each lender sets the details, so treat the table as the usual pattern, not a promise.

How Do the 50% Factor and Ownership Share Combine?

For a business account, qualifying income is roughly average eligible monthly deposits, times your ownership share, times one minus the expense factor. The factor is the lender’s modeling choice. The lender has to rely on verified information, but no regulation sets the number.

Here is the sequence a processor follows.

1. Pick the account type. The lender uses personal statements, business statements, whichever gives the stronger figure, depending on the program.

2. Screen the deposits. Strip transfers, loan proceeds, gifts, refunds and one-time credits. What remains is business revenue.

3. Match deposits to ownership. The K-1 and partnership agreement prove you own the business behind the deposits. Where deposits sit in a business account, your ownership percentage applies to them.

4. Average the clean deposits. Total the eligible deposits and divide by the months in the statement period.

5. Apply the expense factor. This applies to business accounts. The market commonly cites 50%. A CPA or tax-professional letter can support a different factor where the program allows it. In some programs a third-party-prepared profit-and-loss or expense statement is an alternative.

6. Arrive at qualifying income. That figure then goes through debt-to-income, credit, asset and reserve checks.

On the regulatory side, a creditor must make a reasonable, good-faith determination of repayment ability and verify what it relies on. The CFPB’s compliance guide for the ability-to-repay rule lists eight factors and does not dictate a particular underwriting model. A deposit program is one accepted way to document income. Non-QM does not mean no underwriting.

Two Partners, One Deposit Stream

Ownership share is the swing factor. Take one business account showing the same eligible deposits each month, with a 50% factor, and two partners reading from it.

The figures are illustrative, not a program rule. Partner A counts half of the eligible deposits. Partner B counts roughly 15% of them, because 30% of the half left after the factor is 15%. Identical deposits, very different borrowing power.

A minority partner with commingled funds feels this most. Personal and business money in one account makes attribution harder, and the proration can cut qualifying income sharply.

Where Does the General Rule Break?

The 50% pattern bends in several places. These are the cases that change a file.

Personal versus business statements. Personal-statement programs generally count eligible deposits without an expense factor. Business-statement programs apply one. A partner whose distributions land in a personal account can read very differently from one using the partnership’s own account. Whether ownership share applies also depends on the account. Check the program rules instead of assuming.

Double counting. The same dollars can show up in the partnership account and again as a distribution in your personal account. Lenders watch for it. Pick one account path and document it.

Guaranteed payments. These are reported separately from Box 1 ordinary income and Box 19 distributions, and they arrive as deposits. Classifying them cleanly matters.

Distributions versus allocated income. Box 1 can be large while distributions are small. Retained earnings can make the K-1 look better than the cash actually received. A deposit program reads the cash.

K-1 losses. Box 1 can be a loss. A deposit file largely sets that aside and relies on cash flow, though the lender still looks at the trend.

Multiple entities. Statements may be run separately or combined, depending on the program.

A business under 24 months. Statement history may be limited, and some programs work from 12 months.

Declining trend and unexplained credits. A falling deposit pattern, NSF activity or large one-time credits draw scrutiny whatever the factor.

What Leverage and Terms Apply?

Leverage depends on occupancy and transaction type. These are typical network ranges, subject to lender guidelines, credit and loan size.

• Primary residence purchase or rate-term: up to 90% LTV through select lenders. Stronger files earn the top of the range.
• Owner-occupied cash-out (primary or second home): up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio.
• Investment-property cash-out: tops out around 75% LTV.
• Investment purchase on bank statement documentation: varies by lender.
• Asset-depletion alternative: up to about 80% LTV on a primary residence.
• Loan amounts: roughly $125,000 to $3,500,000, with reserves commonly around 6 months of the housing payment.

Occupancy also decides the disclosure regime. An owner-occupied file is a consumer mortgage, so TRID applies. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt. Consumer mortgage licensing for this lane covers 16 states. Every file is underwritten individually, and nothing here is a commitment to lend.

Which Path Fits: Bank Statements, P&L, or DSCR?

Bank statements measure your income. A DSCR loan measures the property’s income. That is the practical dividing line for K-1 partners who also own rentals.

Many investors use bank statements on the home and a DSCR loan on the rentals. On a rental, the file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, so K-1 income and the expense factor largely drop out. Credit, reserves and experience still count. Select lenders in the network will look at sub-1.00 coverage, with LTV and terms adjusting. For the mechanics, see the complete DSCR loans guide.

A 50% factor halves the usable deposits, so size a primary-residence purchase against the haircut, not the gross deposits. For a partner whose K-1 shows low income after depreciation but whose cash flow is strong, that is often the right math. A P&L route or a CPA factor letter may help where a program permits it.

What Should a Partner Prepare First?

Clean separation and complete documents prevent most preventable gaps.

• Ownership proof: the K-1s and the operating or partnership agreement.
• Statements: every page, consecutive months, downloaded from the bank.
• Explanations: written letters for any large or unusual deposit.
• Account hygiene: keep personal and business funds in separate accounts, and avoid large unexplained deposits in the statement window.
• CPA question: ask whether a factor letter is permitted under the program you are targeting.
• Reserves: document liquid funds that can cover about 6 months of the housing payment.

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 not legal or tax advice, so consult an attorney or CPA about your own situation.
