Super Jumbo Bank Statement Checklist For Practice Owners With K-1 — The Quick Read: Practice owners with K-1 income (physicians, dentists, attorneys, group partners) usually don’t qualify well on traditional personal-income documentation alone, because deductions and depreciation shrink taxable income below actual cash flow. Bank statement programs qualify on deposits instead, and separate paths exist for K-1-heavy files versus deposit-heavy files. This checklist walks through both, step by step, plus where the general rule breaks.
Why Tax Returns Undersell What a Practice Actually Earns
A dental practice with three chairs, a CBCT scanner, and six employees can generate strong cash flow while showing modest net income on paper. Equipment depreciation, Section 179 write-offs, and payroll for staff all reduce taxable income without reducing what actually lands in the bank. A K-1 reflects that reduced number — not the practice’s real capacity to support a mortgage payment.
This is the gap bank statement lending was built to close. Instead of reading Line 1 of a K-1 or the bottom line of a Schedule C, underwriting reads what actually moved through the accounts. For an owner-physician or owner-dentist with real overhead, that difference between taxable income and deposit-based income can be substantial — often enough to change what loan size is realistic entirely.
Key Terms Defined
K-1 (Schedule K-1): A tax form that reports a partner’s or shareholder’s share of a partnership’s or S-corp’s income, deductions, and credits — it reports what was earned, not necessarily what was distributed in cash.
Expense factor (or expense ratio): The percentage of business account deposits a lender assumes went to operating costs before counting the remainder as qualifying income.
Ownership threshold: The percentage of a business a borrower owns that determines whether they’re treated as self-employed (deeper documentation) or as a passive recipient of “other income” (lighter documentation).
Reserves: Liquid funds a borrower must have left over after closing, measured in months of the future payment obligation.
Case-by-case review: Files above a certain loan size aren’t matched to a published rate sheet — they go to a lender for individual underwriting judgment before submission.
How the 25% Ownership Line Changes Everything
A practice owner with 25% or more equity in the entity is treated as fully self-employed. Below that threshold, the K-1 income can sometimes be treated more like passive “other income” with lighter documentation.
For most practice owners — the physician who bought into a group, the dentist who owns her own office, the attorney with equity in the firm — that 25% line is already crossed. The associate two years into a group practice with no ownership stake is a different file entirely, and usually a simpler one.
The Two Qualification Paths for a Practice Owner With K-1
A practice owner generally has two non-QM roads available. They can qualify off business or personal bank deposits, or they can qualify off the K-1 and traditional personal-income documentation directly. These are not the same analysis. Picking the wrong one can shrink or inflate what a lender is willing to work with.
Path 1 — Deposit-based (bank statement). Twelve or twenty-four months of statements get totaled, transfers and non-income credits get stripped out, an expense factor gets applied if the deposits ran through a business account, and the result gets divided by the number of months. Across the wholesale network Lendmire works with, expense ratios are typically tiered by staffing level, running lowest for a service business with no employees, stepping up for a small handful of employees, and rising further for larger staffs or any product-based business — though an accountant-provided ratio or a profit-and-loss method (capped around 80%) can often replace the default when a practice’s real overhead differs from the flat assumption. A high-overhead dental practice with real equipment leases and a larger staff is exactly the kind of file where a CPA letter supporting a lower ratio can matter.
Path 2 — K-1/tax-return based. This path reads the actual filed returns and asks whether the income reported was distributed or accessible. Underwriting logic that non-QM lenders commonly still borrow from requires confirming the business has adequate liquidity to support any withdrawal being counted, and getBlueprint’s breakdown of K-1 mechanics walks through exactly which lines matter — Line 19a on a Form 1065 K-1, Line 16D on a Form 1120S K-1 — and why Schedule L, the business balance sheet, gets reviewed too.
Most practice owners with high legitimate write-offs do better on Path 1. A practice owner with a cleaner, growing K-1 and a documented two-year distribution history may do just as well, or better, on Path 2. This isn’t a rule to memorize so much as a math problem to run both ways before choosing.
Transfers, Owner Draws, and What Counts
Money the borrower moves from their own business account into a personal account counts in full, at 100%, in most programs across Lendmire’s network. This matters because a lot of practice-owner cash flow arrives this way — the practice’s operating account pays the owner a draw, and that draw lands in a personal checking account before it ever touches a paycheck.
What doesn’t count: transfers between the borrower’s own accounts that aren’t tied to income (moving savings around), loans from a business partner showing up as a deposit, and one-time items like an equipment sale or an insurance settlement. These get flagged and explained, not counted as recurring income. A large, unexplained one-time deposit close to application is one of the more common reasons a file gets extra scrutiny — flag it upfront with a letter of explanation rather than letting underwriting find it first.
S-Corp Versus Partnership: Why the Structure Changes the File
An S-corp practice owner who is also an employee must take reasonable W-2 compensation before distributions count. Lenders check that the salary matches industry norms for the role before crediting distributions on top of it. A partnership structure works differently: partnerships have more flexibility in when and how much gets distributed. This sounds like an advantage, but it often becomes a documentation burden instead. Without guaranteed payments or a steady two-year distribution history, a partner may need to lean on business financials to prove the income is actually accessible. Fannie Mae’s guidance on K-1 income from Form 1065 or 1120S explains why. Non-QM underwriters apply the same logic when reading a partner’s file.
A practice owner who recently restructured from a straight 1099 or sole-proprietor setup into an S-corp for FICA savings should expect the same friction. That restructuring is a smart tax move, but it resets the documentation clock in a way that can complicate a mortgage application filed too soon after the change.
The Checklist: What Actually Goes in the File
Income documentation (pick the lane, then gather everything for it):
- 12 or 24 consecutive months of bank statements (business or personal, never a substitute transaction history)
- Two years of K-1s and business income documentation if running the K-1 path
- A CPA or enrolled-agent letter supporting an actual expense ratio, if the default assumption undersells the practice’s real cash flow
- Proof of ownership percentage in the practice (operating agreement, K-1 ownership line, or similar)
Credit and liability documentation:
- A credit report clean of recent late mortgage payments
- Letters of explanation for any large, unusual, or one-time deposits
- Documentation of any other financed real estate, since reserve requirements scale with portfolio size These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Asset and reserve documentation:
- Two months of asset statements showing post-closing liquidity
- Retirement account statements, where relevant, since these typically count at a reduced value rather than face value
Property documentation, if the purchase is a rental rather than a residence:
- The file shifts to appraisal-driven rent rather than personal income at all — Lendmire’s complete DSCR loans guide walks through how that qualification works when a practice owner is buying investment property rather than a primary home.
Size and Leverage: What a Practice Owner Can Actually Borrow
Loan sizes in Lendmire’s wholesale network run from $300,000 to $30,000,000 across two separate structures — a portfolio non-QM bank-statement program that carries to $6,000,000, and a bank portfolio program that carries twelve-month-statement files up to $30,000,000 on its own ladder (65% at the lower end, stepping down to 60% by $10,000,000 and 55% by $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower). These are two different structures, not one number, and the bank program’s ladder overlaps the portfolio program between roughly $4,000,000 and $6,000,000 before standing on its own above that.
Leverage on a primary residence steps down as size climbs. On most files across the network, a practice owner can see around 90% purchase leverage near $1,000,000, tapering to roughly 85% near $2,000,000, 80% near $3,000,000, and 75% at the top credit tier up toward $4,000,000. Above $4,000,000, every file gets reviewed case by case before submission — nothing at that size is a flat published number, and credit floors typically climb to the 700-plus range at the same time. Second homes and investment properties generally run about five points lower in leverage at every size band, and cash-out proceeds are typically capped around $1,500,000 above 60% LTV on the portfolio program.
Take a practice owner buying a $2.8 million primary residence. On most files, they’re generally looking at leverage in the low-80s percent range. Credit in the low-700s supports the strongest end of that range. This is subject to full underwriting and lender guidelines — never a guarantee.
Reserves: The Part Practice Owners Underestimate
Reserve requirements scale with loan size and with how many other properties the borrower already finances. Typically, that’s around 3 months of payments up to $500,000, 6 months up to $1,500,000, and 9 months above that — plus roughly 2 additional months for every other financed property, capped near 12 months. A first-time real estate investor, even one buying a modest rental alongside a large personal residence, should generally plan on the full 12-month reserve requirement regardless of the loan size on the residence itself.
For a practice owner simultaneously financing a large home and growing a rental portfolio, this is the number that gets underestimated most. Liquidity needs to be planned months ahead, not assembled the week before application.
Where the K-1 Path Runs Into Trouble
Declining K-1 income across two years invites more questions, even in a fully documented non-QM file — a meaningful year-over-year drop typically needs a letter of explanation regardless of which program is used.
Some practice owners converted from sole proprietor to S-corp within the last year or two. They often lack the distribution history that some liquidity-relief provisions look for. This can push the file toward the deposit-based path by default, not by choice.
Say a practice owner is also buying an investment property on the side, with short-term rental income involved. That income doesn’t factor into the standard appraisal-based rent used to qualify the property. The appraiser values the property’s long-term market rent, not the nightly-rate business running inside it. Short-term rental rules can vary by city, county, HOA, and property type. So investors should confirm local rules before relying on projected rental income at all.
A Worked Example: Reading a Partner’s File
Consider a physician-partner with a modest base K-1-reported guaranteed payment plus a variable annual distribution on top of it. Read alone, the K-1 might understate what actually reaches the partner’s personal account in a given year — especially if the practice reinvested heavily in equipment that year. Try running the deposit-based path instead: pull 24 months of the personal account where those distributions actually landed. This often produces a cleaner, higher, and more defensible coverage figure than reading the K-1 line by line. This is the practical reason so many practice-owner files end up on the bank statement track even when a K-1 exists. The deposits tell the real story, and the K-1 tells the tax story.
A partner might qualify for more using the tax-return path. This works if they have a strong, rising two-year K-1 distribution history that’s well documented — especially with guaranteed payments involved. Here’s why: Fannie Mae’s framework on guaranteed payments shows that a documented two-year history of guaranteed payments can be added to cash flow without further liquidity proof. The right answer depends entirely on which document tells the stronger story. The practical move is to run both math paths before applying.
Tax treatment can depend on how the funds are used and how the property is held; practice owners should keep clear records and speak with a qualified tax professional before relying on any deduction.

Frequently Asked Questions
Does my K-1 income count the same way as traditional employment income? No. A K-1 reports taxable income, not necessarily cash available to pay a mortgage. Underwriting has to confirm the income was actually distributed or is otherwise accessible, which is a separate analytical step from simply reading the number on the form.
Can I use business bank statements if I own less than 100% of the practice? Generally yes, but most programs require at least 25% ownership before business statements are accepted as a qualifying income source, with income calculated from deposits after an expense factor.
What if my K-1 income dropped last year because I bought new equipment? That’s exactly the scenario where the deposit-based path often works better than the tax-return path — equipment depreciation and write-offs reduce taxable income without reducing actual cash flow, so pulling deposits instead of reading the K-1 line often produces a stronger coverage figure.
Do I need a CPA letter? Not always, but it can help. If the default expense ratio assumption understates the practice’s real cash flow — a low-overhead solo practice, for example — an accountant-provided expense ratio can often replace the flat default and improve the coverage figure.
What happens above $4 million? Every file above that size moves to case-by-case review before submission rather than a published leverage number. Credit expectations typically rise into the 700-plus range, and additional overlays — housing history, seasoning on any credit event, occupancy limits — commonly apply.
