Count K-1 Income When Buying A Second Home — The Quick Read: A K-1 shows your share of a partnership or S-corp’s taxable profit, not necessarily cash you actually received. On a bank statement loan, that number usually doesn’t source your qualifying income at all — your deposit history does. Lenders still glance at the K-1 to confirm ownership percentage and entity type, but the math runs off your bank account, not your tax return. That distinction is exactly why bank statement programs exist for partners and S-corp owners buying a second home.
Why This Trips Up Partners And S-Corp Owners
Here’s the root problem. The IRS treats K-1 ordinary income as taxable the moment it’s allocated to you — whether or not the business ever cut you a check for it. The IRS’s own instructions state that a partner “may be liable for tax on your share of the partnership income, whether or not distributed.” That single sentence explains most of the underwriting headaches K-1 income creates.
If a lender pulls your tax return, they have to figure out whether the $200,000 sitting in Box 1 was actually cash you can use to make a mortgage payment, or just a number your accountant assigned you for tax purposes. That question can take weeks to resolve and often requires a business balance sheet, a liquidity test, and multiple years of returns.
A bank statement loan skips that question entirely. It looks at what actually landed in your account.
Key takeaways:
- A K-1’s ordinary income figure is a tax allocation, not proof of cash received.
- Bank statement programs typically qualify off deposits, not K-1 numbers.
- Ownership percentage on the K-1 still gets checked — usually against a 25% threshold.
- Second homes and investment properties use different leverage tables, so occupancy matters before the loan type gets picked.
- Above roughly $4,000,000, files move to case-by-case underwriting regardless of program.
Key Terms Defined
K-1 — a tax form that reports your share of income, loss, or credit from a partnership, S-corp, or LLC taxed as a pass-through entity.
Bank statement loan — a non-QM mortgage that qualifies a borrower using deposit history from personal or business bank accounts instead of traditional personal-income documentation.
Ownership percentage — the share of a business you own, usually shown on the K-1, which decides whether you’re treated as self-employed for underwriting purposes.
Expense ratio — the percentage of gross deposits a lender subtracts to estimate real, spendable income, since not every dollar deposited is profit.
Occupancy category — the classification of how a property will be used (primary residence, second home, or investment property), which determines which loan program and leverage table apply.
Does The K-1 Even Matter On A Bank Statement Loan?
Mostly no — but not entirely. Across the wholesale programs Lendmire places files with, a pure bank statement approval runs on deposits, not on the K-1’s income lines. The K-1 still gets pulled to confirm two things: your ownership stake and the legal structure of the business.
Trade coverage of the bank statement category describes the core mechanic plainly: eligible deposits get multiplied by ownership percentage and an expense factor to produce a qualifying income figure. That ownership percentage typically comes straight off the K-1’s second section. So the form doesn’t disappear from the file — it just stops being the income source.
Most programs in Lendmire’s network draw the self-employment line at 25% ownership. Linda Keith CPA’s underwriting guidance notes that the SBA uses a 20% threshold for full tax-return review. Residential mortgage underwriting, though, commonly uses 25% or higher. Under 25%, lenders often treat a borrower more like a passive income recipient than a business owner. This can shift the documentation path entirely — sometimes toward the borrower’s personal deposits rather than the business’s.
The Ordinary Income vs. Distribution Problem
This is where most K-1 borrowers get confused. A K-1 has two very different numbers on it, and they don’t mean the same thing to an underwriter.
Ordinary business income is your allocated share of profit — the number that creates your tax bill. Distributions are the actual cash the business paid out to you. Zeitro’s underwriting explainer draws this line directly: distributions aren’t automatically countable as qualifying income unless they’re regular and recurring, and minority owners in particular get scrutinized on whether they can actually pull cash out of the business at will.
Here’s the practical version of that problem: a 100% owner of an S-corp can show six figures of ordinary income on the K-1 and still get told that figure can’t be used for qualification — because the money was reinvested in the business rather than distributed. If that same amount had come out as an actual distribution, it typically could be counted. The K-1 doesn’t tell a lender which scenario happened; the bank statements do.
That’s the entire argument for why a bank statement loan sidesteps this fight. Instead of arguing over whether $200,000 of ordinary income was “really” available to the borrower, the underwriter just looks at what actually deposited into the account over 12 or 24 months.
How The Deposit Math Actually Runs
On the bank statement programs Lendmire’s team works with, qualifying income works this way: eligible deposits get divided by the number of statement months, after an expense ratio is applied. Expense ratios generally vary based on staffing levels and whether the business sells a physical product or a service. However, an accountant-provided ratio can be used instead. A profit-and-loss method is also available on many files. It’s generally capped around an 80% expense allowance.
One detail matters a lot for K-1 borrowers: transfers from your own business into your personal account typically count in full. There’s no expense haircut applied. That’s because the money already passed through the business’s own deposit stream once.
Twelve months of statements is standard on the fastest-moving portfolio program in Lendmire’s network; 24 months is used elsewhere and can sometimes smooth out a volatile year. Statements need to be consecutive. A printed transaction history from online banking generally won’t substitute for the actual statements.
Credit requirements on these programs typically start around a 660 floor, stepping up to roughly 700 on higher-balance files. Debt-to-income up to 50% is common on most files, subject to lender guidelines. Reserve requirements generally scale with loan size — often three months of reserves on smaller loans, stepping up toward nine months on larger ones, plus additional months for each other financed property an investor already carries.
Second Home Or Investment Property? Pick The Occupancy First
This decision happens before the loan type gets chosen — and it changes everything downstream. A second home is a property you personally use part of the year and don’t rent out full time. An investment property is bought purely for rental income. Those two categories run on entirely different products.
Is the property a genuine second home — a place where you’ll actually spend time? Then DSCR loans generally aren’t the right tool. That’s because DSCR financing qualifies mainly on the property’s own rental income covering the payment, subject to lender guidelines — not on your personal K-1 or bank deposits. Take a K-1 partner buying a lake house for their own use. They’re a bank statement, asset-based, or profit-and-loss candidate — not a DSCR candidate. Why? There’s no rental income for the property to qualify on.
On the second-home leverage tables Lendmire’s network runs, purchase leverage typically starts around 85% on loans between roughly $300,000 and $1,000,000 with a credit profile around 700 or better, stepping down as loan size grows — around 80% purchase leverage in the $1,000,000 to $2,500,000 range with credit generally in the 680-720 band, and tightening further past $3,000,000. Above roughly $4,000,000, every file in this space moves to case-by-case underwriting before submission — never a flat percentage quoted at that size.
If a borrower plans to rent the property out even part of the year, lenders will often ask that question directly, and misclassifying occupancy can trigger a resubmission under different reserve and leverage rules. This is a common mistake: buyers assume “second home” and “light rental” are the same category. They aren’t, and the leverage table treats them differently.
What Can Go Wrong
A few patterns show up repeatedly on K-1 files headed toward a bank statement approval.
Multiple K-1s from multiple entities is the first one. Real estate investors who also run several LLCs often show up with three or four K-1s in a single file. Each entity’s account has to be separately screened for ownership percentage, commingling, and the right expense ratio — one clean K-1 is straightforward; four is a longer conversation.
New or recently restructured businesses are the second pattern. If the entity generating the K-1 changed structure or ownership recently, a lender may ask for a longer look-back or a CPA letter to confirm the ownership percentage is stable, not just a recent paper change made ahead of the loan application.
Commingled accounts are the third. If a borrower’s personal and business deposits sit in the same account without a clean trail, the ownership-percentage math gets harder to verify, and a program may ask for separate business bank statements instead of relying on personal deposits alone.
Occupancy drift is the fourth issue. A borrower may buy a property as a “second home” but later list it for short-term rental. This can create a mismatch between what was disclosed and how the property is actually used. That’s a separate issue from financing, but it’s worth knowing before you sign anything.
Who This Fits — And Who It Doesn’t
This path tends to fit self-employed partners, S-corp shareholders, and LLC members. Their traditional personal-income documents often understate real cash flow. This can happen because of reinvested profit, aggressive deductions, or a business that simply retains earnings instead of distributing them. It also fits founders, physicians, attorneys, and investors who own 25% or more of an operating business. These borrowers can point to steady deposit activity even when the K-1’s bottom line looks modest.
This loan type doesn’t work as well in two cases. First: a passive minority owner whose only income is an occasional distribution. There’s no deposit pattern to show, so it’s a poor fit. Second: someone buying a property they plan to rent out. That situation usually calls for a rental-income-based product like DSCR instead. If you’re weighing that choice, you can compare how a K-1 borrower uses bank statement income against DSCR qualification directly. This loan also doesn’t fit someone who can’t produce 12-24 consecutive months of statements. Gaps or non-consecutive records generally aren’t accepted as substitutes.
For a K-1 borrower funding the down payment with help from family, it’s worth knowing that gift funds on a second home purchase follow their own documentation rules, separate from the income side of the file — gift fund guidelines for a second home down payment cover that piece.
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.

Frequently Asked Questions
Does a K-1 automatically disqualify me from a bank statement loan? No. A K-1 doesn’t disqualify anyone — most bank statement programs simply don’t use it to calculate income in the first place. The form is checked for ownership percentage and entity type, then the deposit history takes over as the qualifying document.
What if my K-1 shows a loss instead of income? A loss on the K-1 generally doesn’t get counted against you on a pure bank statement loan, since the program isn’t reading that line to begin with. What matters is whether the business’s actual deposit activity supports the income you’re claiming from it.
Can I use K-1 income from a business I own less than 25% of? It depends on the lender and the file. Ownership under roughly 25% often shifts a borrower away from self-employed underwriting entirely, since that threshold is the common dividing line across most programs Lendmire’s network works with.
Do I need two years of traditional personal-income documentation for a bank statement second home loan? Typically no — the whole point of the program is qualifying on 12 or 24 months of bank statements instead of traditional income documentation. Some files still request a CPA letter or a K-1 to confirm ownership percentage, but full multi-year return documentation usually isn’t the standard path.
Is a second home treated the same as an investment property for financing? No. They’re separate occupancy categories with separate leverage tables. A second home is a property you personally use; an investment property is purchased for rental income, and that distinction determines which loan program and leverage limits apply.
