Super Jumbo Bank Statement Loan Reads The Expense Factor — The Quick Read: A lender treats a slice of every business deposit as overhead, not income, before it counts toward qualifying. That slice is called the expense factor. On most files it’s a flat 20%, 40%, or 50% depending on business type and employee count, though a CPA-documented number or a profit-and-loss method can move it. On a super jumbo file — a loan running well into the millions — that percentage decides whether the deal clears at all, because the qualifying-income gap between a 20% factor and a 50% factor gets enormous at size.
This isn’t a regulator’s rule. There’s no federal agency that sets it. It’s a wholesale-lending convention, and it varies from program to program — which is exactly why understanding it matters more than memorizing one number.
Key Terms Defined
Expense factor (also called expense ratio): the percentage of gross business bank deposits a lender subtracts before counting the rest as qualifying income — because a business account holds payroll, rent, and vendor payments mixed in with real profit, not pure earnings.
Qualifying income: the monthly income figure a lender actually uses to calculate debt-to-income, after all adjustments — this is what gets compared against the mortgage payment, not the raw deposit total.
Bank statement loan: a non-QM mortgage that verifies income through 12 or 24 months of bank deposits instead of traditional personal-income documentation or W-2s — built for self-employed borrowers whose returns understate real cash flow.
Super jumbo: an industry-invented size tier, not a government-defined one — generally a loan north of $3 million, though every lender draws its own line.
Debt-to-income (DTI): the percentage of monthly qualifying income that goes toward debt payments, including the new mortgage — this is the number the expense factor ultimately feeds.
How the Expense Factor Actually Gets Applied
The math is simple once you see it: total eligible deposits over the statement period, divided by the number of months, times one minus the expense factor. A borrower with strong gross deposits and a low expense factor ends up with far more qualifying income than one with the same deposits and a high factor — same cash flow, very different loan approval.
Across the wholesale network Lendmire works with, the expense factor isn’t one number — it’s tied to what kind of business generated the deposits. A solo service business with no employees typically gets the most favorable treatment: a 20% factor is common, meaning 80% of deposits count toward income. A business with one to five employees usually lands around a 40% factor. A staffed operation with six or more employees, or any business that sells a physical product, typically defaults to 50% — half the deposits get treated as overhead.
There’s a fourth path too: an accountant-provided ratio, or a profit-and-loss method that can run up to 80% depending on the file. None of these are guaranteed outcomes — they’re the range Lendmire typically sees offered through select lenders in its network, subject to full underwriting.
One detail that surprises a lot of borrowers: transfers from the borrower’s own business into a personal account count in full — no haircut at all. If a business owner regularly moves owner draws into a personal checking account, that money is read differently than deposits sitting in the business account itself. This distinction alone can meaningfully change which lookback strategy makes sense for a given borrower.
Why Business Deposits Get Haircut and Personal Deposits Usually Don’t
Business accounts mix revenue with overhead; personal accounts generally don’t, because the borrower already paid business expenses before that money hit a personal account. That’s the entire logic behind the split, and it’s why the same $500,000 in annual deposits can produce very different qualifying income depending on which account it landed in.
A business account holding substantial gross deposits each month isn’t the same as that amount in income — some of it went to payroll before it ever touched that account, some to rent, insurance, and suppliers. A lender has no way to know the real margin without looking at documentation, so the expense factor is a stand-in for that unknown. Personal account deposits, by contrast, are typically read closer to face value, since the borrower already covered personal costs with after-tax dollars.
This is also where documentation becomes leverage rather than paperwork. Instead of accepting whatever fixed ratio applies to the business type, a borrower can bring an accountant-provided expense ratio. If the real overhead is lower than the fixed default, that documentation can materially increase qualifying income. Sometimes it’s enough to change the loan amount, the leverage tier, or whether the deal clears at all on debt-to-income.
What This Looks Like at Super Jumbo Size
The dollar impact of the expense factor scales with the loan, which is exactly why it matters more here than on a smaller file. A borrower buying a $400,000 property with modest deposits might absorb a less favorable expense factor without much consequence. A borrower financing a property in the multi-million-dollar range doesn’t have that cushion — every percentage point of expense factor moves qualifying income by a meaningful amount, and that income has to support debt-to-income up to 50% on most files in Lendmire’s network.
Loan sizing at this end of the market runs through two separate wholesale paths. A portfolio non-QM bank-statement program typically carries files to $6,000,000. A separate bank portfolio jumbo program, built around twelve-month statements, carries loans on its own size ladder out to $30,000,000 — roughly 65% loan-to-value to $5,000,000, 60% to $10,000,000, and 55% up to $30,000,000, with interest-only capped at 60% or the band’s ceiling, whichever is lower. These are two different products with two different leverage ladders, not one flat number for the whole range.
Leverage steps down as the loan size climbs. On a primary residence, typical ceilings run around 90% up to roughly $1,000,000, stepping down through the 80s in the $2,000,000–$3,000,000 range, down toward 75% at the top credit tier near $4,000,000. Above that, every file gets reviewed case by case before submission — never a flat “up to” figure at that size. Second homes and investment properties generally price about five points lower than a primary residence at every size band.
Credit floors also tighten as loans get bigger. Most files in the network start around a 660 floor on the portfolio program, with a 700 floor once a loan crosses into the super-jumbo range above roughly $3,500,000 on a primary residence or $3,000,000 on a second home or investment property. Reserve requirements climb too — typically three months of payments up to $500,000, six months up to $1,500,000, and nine months above that, plus additional months for each other financed property a borrower holds.
None of these are universal figures — they reflect what Lendmire typically sees offered through select lenders in its network, subject to full underwriting on every file.
The Documentation That Changes the Math
An accountant-provided expense ratio can move a borrower off the fixed default and onto a lower, documented number — but only with real support, not a verbal claim. This is the single biggest lever a self-employed borrower controls in the entire process, and it’s worth understanding before assuming the default number is fixed.
Lendmire’s network generally wants 12 or 24 consecutive months of statements. These can be personal, business, or both. Business statements require at least 25% ownership in the entity generating the deposits. Transaction histories printed from an online banking portal typically don’t substitute for actual statements. The months need to be consecutive, and any gaps raise questions.
Two related articles cover this in more detail. Super jumbo bank statement loan requires a CPA explains when an accountant letter becomes necessary instead of optional. What a CPA expense letter needs to satisfy a super jumbo file covers the documentation standard lenders actually look for.
Beyond the expense factor itself, there are asset-based paths for borrowers whose deposit history doesn’t tell the full story. One option is an asset allowance, which divides liquid assets by 36, 60, or 84 months. Another is an assets-only path with no DTI calculation at all, used when liquidity covers the loan amount plus costs. These paths exist specifically for high-net-worth borrowers whose income doesn’t show up cleanly through traditional personal-income documentation or monthly deposits.
Where DSCR Fits Into This Conversation
If you’re financing a rental instead of a primary residence, the expense-factor conversation may not apply at all. A DSCR loan qualifies mainly on whether the property’s rental income covers the monthly payment, subject to lender guidelines — not on your personal or business deposits. Lendmire’s complete DSCR loans guide covers the full mechanics.
That’s a fundamentally different qualification philosophy, not just a variation on the same math. With bank statements, a borrower proves their own income through deposit patterns and an expense factor. With DSCR, a borrower proves the property itself brings in enough rent to cover its own payment. There’s no expense ratio and no personal income documentation at all. DSCR loans are built for non-owner-occupied investment properties. Because they’re business-purpose investor loans, lenders review them differently than a standard owner-occupied mortgage.
For a self-employed investor buying a rental property specifically, this often means the expense-factor question never comes up — the file runs on the rent roll instead. Worth understanding both paths before assuming bank statement financing is the only route for a self-employed buyer.
Common Mistakes Borrowers Make With the Expense Factor
The most common error: assuming the flat default is often a strong option. A borrower who runs a low-overhead consulting business but accepts a 50% factor because nobody mentioned an accountant letter is leaving real qualifying income on the table — money that could change the leverage tier or loan size available.
The second common error: commingling personal and business transactions in one account. When both types of activity run through a single account, an underwriter has to separate them before applying any expense factor, which slows the file and sometimes produces a less favorable read than clean, separate accounts would.
The third: assuming actual withdrawals will never be checked against the claimed expense ratio. Underwriters look at deposit and withdrawal patterns to confirm the claimed ratio is realistic — a business with withdrawal activity suggesting overhead well above 50% typically gets rerouted to a different calculation method or a different program entirely.
Frequently Asked Questions
Can I choose a lower expense factor than the lender’s default?
Only with documentation. An accountant-provided expense ratio, or a profit-and-loss method, can replace the fixed default of 20%, 40%, or 50% — but the borrower can’t simply request a lower number without support. Lendmire’s network typically wants an accountant letter or P&L that holds up against actual deposit and withdrawal activity.
Does the expense factor apply to personal bank statements too?
Generally no. Personal account deposits are typically averaged directly with no expense-factor deduction, because the borrower already covered personal costs with after-tax dollars before that money landed in the account. The expense-factor haircut is a business-account mechanic specifically.
What happens if my business has both personal and business transactions in one account?
The underwriter has to separate the two before applying any calculation, which usually means more documentation and a slower review. Keeping personal and business banking separate is one of the simplest things a self-employed borrower can do to streamline a bank statement file.
Is a bank statement loan the same thing as “no income verification”?
No. A bank statement loan still verifies income — just through deposits and an expense-factor calculation instead of traditional personal-income documentation or pay stubs. Under the CFPB’s ability-to-repay rule, lenders on consumer mortgages must still find out, consider, and document income, assets, employment, credit history, and monthly expenses before approving a loan.
Why would I use a DSCR loan instead of a bank statement loan for an investment property?
If the property being purchased is a rental, DSCR financing often sidesteps the entire expense-factor question because it is reviewed on the property’s rent covering its payment rather than the borrower’s personal income. Comparing the two — DSCR loan vs. bank statement loan for investors — is worth doing before assuming bank statement financing is the only path for a self-employed buyer of rental property.
A Growing Segment of the Market
Non-QM lending, the category bank statement loans belong to, has been expanding fast. HousingWire reports non-QM originations climbing toward $175 billion, up from $108 billion the prior year, with loans above $1 million now making up roughly 28% of new production. That growth means more self-employed, high-net-worth borrowers are running exactly this expense-factor math every day — not a fringe calculation, but a mainstream part of how large loans get sized.
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.
