How a K-1 Partner Qualifies Using a Bank Statement Self-Employed Mortgage

The Quick Read: A K-1 partner qualifies by letting the lender read cash deposits in business or personal bank accounts instead of the K-1 line items, then applying an expense factor and the partner’s ownership share to turn those deposits into monthly income that still has to clear debt-to-income, credit, asset, and reserve checks. The loan is reviewed on documented income under the applicable program, subject to lender guidelines.

• Your K-1 shows your share of partnership income on paper. Deposits show the cash that actually reached you.
• Personal statements count with no ownership math. Business statements are cut by an expense factor and by your ownership percentage.
• Ownership share is the biggest swing factor. A 100% owner and a 30% partner with identical deposits qualify very differently.
• Our network typically uses 12 months of statements, and the strongest primary-residence files reach up to 90% LTV on a purchase or rate-and-term refinance.
• If your income is rental property, a DSCR loan may fit better, because the property’s rent is tested instead of your personal income.

Why a K-1 Understates What a Partner Really Earns

A K-1 reports your separate share of the partnership’s items, allocated under the partnership agreement. Depreciation, payroll, and contractor costs shrink that number. A partner can also be taxed on a share of income whether or not the partnership pays it out. The gap between taxed income and cash received works against you in traditional personal-income review.

Picture a partner whose K-1 shows a small profit, or even a loss, because of depreciation. Deposits into the account they draw from stay strong every month. A tax-return lender sees the loss. A bank statement lender sees the cash. That mismatch is the main reason partners move to this kind of program.

Bank statement loans are a non-QM product. Non-QM means the loan sits outside the standard agency box and is underwritten under the lender’s own documentation rules. As HousingWire’s non-QM guide explains, these programs use 12 to 24 months of personal or business statements, and an expense factor may apply. In our network, 12 months is the typical documentation period.

Key Terms Defined

• K-1: A tax form showing one partner’s share of a partnership’s income, losses, and other items.
• Distribution: Cash the partnership actually pays out to a partner, which can differ from the income allocated on the K-1.
• Guaranteed payment: A payment to a partner for services or capital that does not depend on partnership profit.
• Expense factor: The percentage of business-account deposits a lender assumes goes to operating costs, which is lender-set and commonly around 50%.
• Ownership share: The partner’s percentage of the business, usually proven with the operating agreement, the K-1, or a CPA letter.
• Debt-to-income (DTI): Your monthly debts divided by your qualifying monthly income.

How a Partner Qualifies, Step by Step

Underwriting follows a consistent order. Each step narrows the deposits into a number the lender can use.

1. Prove ownership. You document your percentage with the operating or partnership agreement, the K-1, or a CPA letter. In practice the K-1 serves as ownership proof here, not as the income source.

2. Choose the account type. Personal statements count deposits directly. Business statements run deposits through an expense factor and your ownership share.

3. Pull consecutive statements. Our network typically asks for 12 months. Some lenders in the market will look at 24.

4. Screen the deposits. The underwriter strips out transfers between your own accounts, loan proceeds, refunds, and one-time items.

5. Apply the formula. Eligible average deposits, reduced by the expense factor and multiplied by your ownership share, produce qualifying monthly income.

6. Run personal DTI. The loan still looks at you personally. Qualifying income is compared against your monthly debts.

7. Underwrite the rest. Credit, assets, reserves, and the property get the same scrutiny as any other file.

Step 4 is not optional. The CFPB’s ability-to-repay compliance guide says a creditor relying on funds flowing into an account must confirm those inflows are the consumer’s own income. Deposit screening is how lenders meet that standard. It is also why the phrase “no underwriting” misdescribes these loans. The same guide requires verifying income with reasonably reliable third-party records, and bank statements are one such record.

A Worked Example (Hypothetical, Index Numbers Only)

These are modeled assumptions, not market data. Say eligible average monthly deposits equal an index of 100 after screening. Assume a 50% expense factor and a 40% ownership share.

• Deposits after screening: 100.
• After the expense factor: 50.
• After the ownership share: 20.

That 20 is the qualifying income this partner carries into the DTI test. A 100% owner with the same deposits would carry 50. A partner who deposits to a personal account may skip the factor and the ownership math, because those deposits are already the partner’s own money. The lender then asks different questions: where the money came from, and whether it will keep coming.

Two details can change the result. A CPA-prepared expense ratio, where a program allows it, can lower the factor and raise income. Declining deposits across the statement period can pull the average down or draw more questions.

Which Deposits Count and Which Don’t

Treat this table as a market convention. Each lender’s program sheet decides the details. A deposit that comes from your own transfer looks the same as income on a statement, so unlabeled or commingled accounts are where files get stuck. Cash-heavy accounts raise the same problem, because the underwriter cannot trace the source.

Personal Accounts vs. Business Accounts

Personal statements are simpler. Deposits count with no ownership math, and this works best when your partnership pays you directly. Business statements mean the lender is reading the entity’s cash flow, not yours. That is why the expense factor and your ownership percentage apply.

Many programs also set an ownership floor for using business statements. If you hold a minority stake, the business route may be closed or limited, with no partial credit. The 25% mark is a familiar benchmark because conventional guidelines use it too. The Fannie Mae Selling Guide treats borrowers under 25% ownership as K-1-only borrowers who must show actual distributions or business liquidity. Agency rules do not govern bank statement programs, but the number explains why lenders ask about your percentage first.

Access matters as much as percentage. A partner who cannot access or control the operating account usually cannot use its deposits. If the account is shared, document your access.

K-1 Underwriting vs. Bank Statement Underwriting

Investors with several partnerships should compare three routes: bank statement, DSCR, and traditional personal-income review. Each reads a different part of your finances. Our network includes lenders that will review more than one route for the same borrower, but the programs themselves do not blend.

Leverage, Loan Size, and Reserves

Leverage depends on what the property is used for. These figures are typical of select lenders in our network and are subject to lender guidelines, credit, and loan size.

• Primary residence, purchase or rate-and-term refinance: up to 90% LTV, with stronger files earning 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-property purchase on bank statement documentation: varies by lender, so there is no single number to quote.
• Asset-depletion alternative: qualifying from liquid assets runs to about 80% LTV on a primary residence.

Loan amounts generally run from $125,000 to $3,500,000. Reserves are commonly around six months of the housing payment. Term lengths follow each lender’s program sheet, so do not assume a 40-year or interest-only structure on this lane. Extended structures are mostly a DSCR-side feature.

Occupancy also decides the paperwork. An owner-occupied file is a consumer mortgage, and the standard consumer disclosure rules, including TRID, apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is a business-purpose loan and is exempt from TRID. Lendmire’s consumer mortgage licensing covers 16 states, so availability depends on where the property sits. Payment and pricing figures live only in the calculator, which is an illustrative estimate, not a quote.

Business Funds for Down Payment and Reserves

Using business-account money for a down payment or reserves can take a haircut. In one practitioner answer on a BiggerPockets forum, some lenders discount business funds by the partner’s ownership share, sometimes with an expense factor on top. That is anecdotal, and each program sheet sets its own treatment. The practical move is to keep down-payment and reserve money in your own name well before applying.

Common Partner Pitfalls and Fixes

• Mixed or unlabeled accounts. Separate personal and business flows early. Give the underwriter a clean read.
• A K-1 showing a loss. This does not disqualify you here. Deposits drive the income in a bank statement program, while traditional personal-income review would use the loss.
• Several entities. Each entity needs its own ownership proof and statements. Do not blend accounts across them.
• Declining income. A downward trend across the statement period can reduce the average or trigger questions. Be ready to explain it.
• Newly admitted partners. A short history may be accepted in some programs with prior related experience, but that is program-specific.
• Partnership restructured or sold. Expect the underwriter to ask whether the deposit stream will continue under the new arrangement.

The 60-Day Prep Plan

Start by collecting the partnership agreement, your latest K-1, and 12 months of statements from every account you plan to use. Mark transfers, loan proceeds, and one-time deposits yourself. Avoid large unexplained deposits and new debt. If a CPA can prepare an expense ratio or a letter confirming your ownership, ask early. This is where the loan officer can tell you whether personal or business statements give you the stronger number before you commit.

When Another Path Fits Better

If you hold rental properties through a partnership, the property’s rent is the test on a DSCR loan, and K-1 and multi-entity complexity barely touch the file. Read the complete DSCR loans guide to see how that loan works. A bank statement loan is a personal-income program, so your DTI applies and the property’s rent is not the primary test.

Tax treatment varies; consult a qualified professional before relying on any deduction or filing position.
