How To Use K-1 Income On A Bank Statement Loan — The Quick Read: A K-1 shows your allocated share of a partnership’s or S-corp’s income, but that number often has little to do with cash you actually control. Bank statement loans sidestep the K-1 entirely and is reviewed against deposits into a business or personal account instead. The catch is proving you have real access to those funds, especially if you own less than 25% of the entity. Get that ownership and access question right, and the K-1 mostly becomes background paperwork.
Why The K-1 Trips People Up
Schedule K-1 is a tax form, not a paycheck. The IRS uses it to report a partner’s or shareholder’s share of business income, deductions, and credits — and critically, a partner can owe tax on income they never actually received in cash, according to the IRS Partner’s Instructions for Schedule K-1. That gap between “allocated” and “distributed” is exactly what trips up borrowers who assume their K-1 number is their real income.
The form also splits income into boxes that behave differently in underwriting. Box 1 is ordinary business income. Box 2 is net rental real estate income. Boxes 4a through 4c cover guaranteed payments, which act more like a salary than a profit share. Lenders treat these boxes differently, and that’s before anyone even opens a bank statement.
Key Terms Defined
K-1 income: your reported share of a partnership’s or S-corp’s profit, loss, or guaranteed payments, whether or not you received cash.
Bank statement loan: a mortgage that qualifies a self-employed borrower using deposit history instead of traditional personal-income documentation.
Expense ratio: a percentage a lender subtracts from business deposits to estimate real costs before counting the rest as income.
Guaranteed payments: fixed payments a partner receives for services or capital, reported on the K-1 but functioning like wages.
DSCR loan: a loan that qualifies based on a rental property’s income instead of the borrower’s personal tax documents.
Step 1: Figure Out Which Document Is Actually Doing The Work
On a bank statement loan, the K-1 is not the qualifying document — deposits are. The lender pulls 12 or 24 months of statements from either the pass-through entity’s operating account or the borrower’s personal account, if distributions land there. Across the wholesale network Lendmire works with, most programs use this deposit total, strip out non-income credits, apply an expense factor on business accounts, and divide by the number of months to land on a monthly qualifying figure. The how income is calculated for a bank statement loan breakdown covers this math in more depth.
For a K-1 partner, that means the tax return’s ordinary income line and the lender’s deposit-based figure can be two very different numbers — sometimes higher, sometimes lower, depending on how much cash the business actually distributes versus retains.
Step 2: Prove You Actually Control The Deposits
This is where ownership percentage becomes an underwriting fact rather than a tax detail. If income runs through a partnership or S-corp account, the lender needs proof you have access to and control over the funds, not just an allocation on paper. That usually means at least 25% ownership in the entity whose account is being used, which lines up with the threshold most residential lenders reference and with the origin point in Fannie Mae’s Selling Guide on Schedule K-1 income, even though DSCR and bank statement programs aren’t agency products.
Real securitization files back this up in practice. Underwriting exception notes on non-QM pools have flagged missing K-1s for related businesses and noted that additional conditions apply once ownership crosses that 25% line. Other file notes describe an inability to verify K-1 income at all for a minority owner under 25%. The lesson is consistent: ownership percentage and documentation completeness — not the mere existence of a K-1 — are where these files usually stall.
Guaranteed payments add another layer of complexity. Take a partner who owns less than 25% of a business and also draws guaranteed payments from that same entity — but the entity reports a loss. This case doesn’t fit neatly into either category. Practitioner guidance from Linda Keith CPA points out that there’s no single standard answer here. Some underwriters add together ordinary income, rental income, and guaranteed payments. Others look at each line separately.
Step 3: Deposits Get Cleaned, Not Just Added Up
A lender totals every credit that hit the account over the lookback window, then strips out anything that isn’t real income — transfers between the borrower’s own accounts, loan proceeds, credit-line draws, tax refunds, and one-time items like an asset sale. On a consumer-purpose loan, this stripping step isn’t optional. The CFPB’s Ability-to-Repay compliance guide is explicit that a lender fails the verification standard if it spots a unidentified deposit and doesn’t chase it down.
Transfers matter especially for K-1 partners. If money moves from the business account into a personal account, that same dollar cannot be counted as income on both statements. Reviewers are trained to catch double-counting, and it’s one of the more common errors self-prepared applications make.
Step 4: Business Deposits Get An Expense Haircut
Once the eligible deposits are isolated, an expense ratio gets applied if the statements come from a business account. Across the programs Lendmire places files with, that ratio typically scales with employee count and business type — running lower for a service business with no employees, moderate for a business with a small staff, and higher for larger staffs or any product-based business — or a ratio an accountant provides directly. Some files instead run on a profit-and-loss method capped at a set ceiling. Transfers the borrower personally moved from their own business into a personal account generally count in full.
For a K-1 partner, this expense factor effectively replaces whatever deductions the partnership’s own tax return already claimed. The lender isn’t looking at the K-1’s expense lines at all — it’s substituting its own deposit-based estimate.
Step 5: Don’t Blend Distributions And Ordinary Income
Ordinary business income and cash distributions are not the same thing. Treating them as equal is a common mistake. Linda Keith CPA’s practitioner training includes a worked example that shows this. A 50% S-corp shareholder’s K-1 listed $276,970 in ordinary business income and $176,914 in distributions. Lenders treated the distribution as real income without much debate. But they needed to look closer at the ordinary income figure — specifically, whether the business could keep paying that amount going forward.
That distinction matters on hybrid-doc files where a lender is weighing K-1 figures alongside bank deposits. It matters less on a pure bank statement file, where the deposit total is what counts regardless of how the tax return characterizes it — though a lender may still want to understand why deposits and the K-1’s reported income don’t match.
When The K-1 Shows A Loss
A K-1 ordinary business loss doesn’t automatically sink the file. On more traditional underwriting paths, that loss typically gets subtracted from the borrower’s other qualifying income, such as W-2 wages. Non-QM lenders have more room to weigh compensating factors — strong deposits, healthy reserves, solid liquidity — instead of applying a rigid offset. The loss reduces the coverage figure; it doesn’t necessarily zero it out, and on a bank statement file where the K-1 isn’t the qualifying document to begin with, a paper loss driven by depreciation often has little bearing on the outcome at all.
The Cleanest Exit: Skip The K-1 Question Entirely
An investor buying rental property can skip this whole analysis with a DSCR loan. This loan qualifies mainly on whether the property’s rental income covers the payment, subject to lender guidelines. It doesn’t rely on personal income documents. The appraisal drives most of the lender’s review. It includes a rental survey — Form 1007 for single-family homes, Form 1025 for multifamily properties. This survey sets the market rent and shows the resulting coverage ratio.
Say an investor’s K-1 shows a paper loss from depreciation, or the partnership kept its earnings instead of distributing them. On a DSCR file, this investor avoids all the ownership-threshold and deposit-tracing issues described above. But there’s a tradeoff: DSCR loans only work for the investment property itself, not for financing a primary residence. Coverage below roughly 1.00x may still work through select lenders in the network, though leverage and terms typically adjust when it does.
Lendmire’s team often sees K-1 partners with messy ownership situations. These may involve multiple entities, thin distributions, or a business that keeps its cash instead of paying it out. When these partners buy rental property instead of a home to live in, they often turn to DSCR loans for exactly this reason.
Investor Impact
For a self-employed partner, contractor, physician practice partner, or law firm equity holder, the K-1 is often the least useful document in the file. That’s because it reflects tax-basis allocations, not the actual cash available to pay a mortgage. Bank statement loans exist to solve this exact problem. They let an investor with strong cash flow but a lean K-1 qualify based on deposits instead of the tax return alone.
An investor who’s also buying rental property can pair these two strategies well. Use bank statement qualification for a primary residence, especially when the K-1’s understated tax income would otherwise sink the file. Then use DSCR for the rental purchase, where personal income documentation doesn’t factor into the analysis at all. The complete DSCR loans guide explains how this qualification works, property by property.
Sizing And Leverage For High-Deposit Borrowers
Bank statement financing through Lendmire’s wholesale network runs from $300,000 to $30,000,000, split across two ladders — a portfolio non-QM program to $6,000,000, and a bank portfolio program that carries 12-month-statement files to $30,000,000 at leverage that steps down as loan size climbs, topping out at 55% loan-to-value (LTV) at the highest tier, with interest-only capped at whichever is lower.
On a primary residence, leverage steps down as loan size climbs: typically up to 90% LTV to $1,000,000, 85% to $2,000,000, 80% to $3,000,000, and 75% at the top credit tier to $4,000,000, with every file above that reviewed case by case before submission. Second homes and investment property generally run about five points lower at every size. Credit typically needs to clear 660 on the portfolio program (700 above the super-jumbo line), with debt-to-income up to 50% and reserves scaling from three months on smaller loans to nine months or more on larger ones. These are typical ranges through select lenders in the network, not guaranteed terms, and every file is underwritten individually.
DSCR loans are business-purpose investor loans, so they’re reviewed differently from a standard owner-occupied mortgage and sit outside the consumer disclosure timelines that apply to a primary-residence purchase.
Tax treatment can depend on how loan proceeds are used and how the property is titled; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Do I need to submit my K-1 if I’m qualifying on bank statements?
Often yes, even though it isn’t the qualifying document — lenders typically want the K-1 to confirm ownership percentage and cross-check that reported entity income roughly lines up with deposit activity. A mismatch isn’t automatically disqualifying, but it usually invites a question.
What if my K-1 ownership is under 25%?
Access and control become harder to document below that threshold, since the entity’s account isn’t presumed to be under your control the way it is above 25% ownership. Some files still work using personal account deposits instead of the entity’s business account.
Can guaranteed payments and ordinary income be combined?
Sometimes, but there’s no fixed industry rule — some underwriters add ordinary income, guaranteed payments, and rental income together, while others evaluate each line on its own. This is one of the more genuinely unsettled areas in K-1 underwriting.
Does a K-1 loss disqualify me from a bank statement loan?
No — a loss typically gets weighed against other income rather than treated as an automatic denial, and on a pure bank statement file the deposit total often matters more than the K-1’s bottom line. A DSCR loan on a rental purchase would bypass this question entirely, since personal income isn’t part of that analysis.
Is a bank statement loan better than a DSCR loan for a K-1 partner?
It depends on what’s being financed — bank statement programs work for a primary or second home where personal income needs to be shown, while DSCR loans work for rental property where the property’s own income drives lender review, subject to lender guidelines. The bank statement loans for K-1 partners guide covers the primary-residence side in more detail.
