The Quick Read: This loan stacks three separate features on one mortgage: a very large balance, income proven by bank deposits instead of traditional personal-income documentation, and an interest structure that stays fixed for ten years and then adjusts. Each feature answers a different question, and each is underwritten on its own terms. Through select wholesale programs, subject to full underwriting, the structure is available to self-employed borrowers whose traditional personal-income documentation understates their real cash flow.
- Size: files run from $300,000 to $30,000,000 across two wholesale programs, and everything above $4,000,000 is reviewed case by case before submission.
- Income: 12 or 24 months of statements, with deposits reduced by an expense ratio before they count.
- Fixed period: ten years of stability, then adjustments every six months for the rest of a typical 30-year term.
- Structure catch: on the bank portfolio program, a 10-year fixed-period adjustable is fully amortizing. Interest-only is limited to the 5- and 7-year versions.
- Biggest planning risk: the reset, not the documentation type.
Key Terms Defined
Super jumbo: a market label for the top tier of jumbo loan sizes. No regulator defines it, so each program sets its own cutoff.
Bank statement loan: a mortgage that qualifies the borrower on documented deposits rather than traditional personal-income documentation or W-2s.
Expense ratio: the share of business deposits the lender treats as costs, not income.
ARM (adjustable-rate mortgage): a loan whose interest changes on a schedule after an initial fixed period.
Index and margin: the index is a market benchmark that moves. The margin is a fixed add-on the lender sets. Together they form the new adjustable rate.
Cap: a limit on how far the adjustable rate can move at the first adjustment, at each later adjustment, and over the life of the loan.
How the Three Layers Fit Together
The cleanest way to understand this product is to stop treating it as one thing. Size decides which programs can even look at the file. Documentation decides how much income the borrower can show. The rate structure decides what the payment does over time.
Those layers interact in a few ways. A larger balance pulls leverage down and reserves up. A bank statement file is sized from the deposit-based income figure. The ARM’s behavior at the reset is a cash-flow question that the income figure has to be able to absorb. Underwriting touches all three, but it asks different questions of each.
For the full picture of how Lendmire approaches these programs, the complete DSCR loans guide covers the property-income side, which is the alternative lane when an investor would rather qualify on rent than on personal deposits.
What “Super Jumbo” Changes
Across the wholesale network, super jumbo is where the rules visibly tighten. The loan-size range is $300,000 to $30,000,000, carried by two programs. A portfolio non-QM bank-statement program handles files to $6,000,000. A bank portfolio jumbo program carries twelve-month-statement files to $30,000,000 on its own ladder: 65% to $5,000,000, 60% to $10,000,000, and 55% to $30,000,000. That second ladder begins above $4,000,000, overlaps the first program to $6,000,000, and stands alone above it.
Leverage steps down as the balance grows. Through select wholesale programs, subject to underwriting, the purchase ceilings run roughly like this:
| Loan size | Primary residence purchase | Investment property purchase |
|---|---|---|
| $300K–$1M | 90% | 85% |
| $1M–$2M | 85% | 80% |
| $2M–$3M | 80% | 75–80% |
| $3M–$4M | 75% | 60% |
| Above $4M | Case by case | Case by case |
Second homes and investment property each take their own ladder. The gap to the primary-residence figure runs from zero to fifteen points depending on the band, so read every figure from the ladder for your occupancy rather than subtracting from the primary number. Above $4,000,000 every figure is a review-dependent ceiling, not a promise.
Overlays also tighten. Above $3,500,000 on a primary residence, and above $3,000,000 on a second home or investment property, the programs typically want a 700 credit floor, a clean housing payment history, 48 months of seasoning after any credit event, and no rural property. Cash-out proceeds cannot count toward reserves at that size.
On most files the baseline credit floor is 660 on the portfolio program and 680 on the bank program. Debt-to-income can reach 50%. Reserves step up with size: 3 months to $500,000, 6 months to $1,500,000, and 9 months above that, with extra reserves for each additional financed property.
How Bank Statement Income Becomes a Loan Size
Underwriting treats deposits as raw material, not as income. The sequence runs in five steps.
1. Pick the statement window. The borrower supplies 12 or 24 consecutive months of personal or business statements. The bank program uses 12. Statements must be consecutive, and a transaction history never substitutes for them.
2. Screen the deposits. Underwriters strip out transfers between the borrower’s own accounts, refunds, loan proceeds, and other items that are not earnings.
3. Apply the expense ratio. On business statements, the borrower must own at least 25% of the business. Fixed ratios of 20%, 40%, or 50% apply depending on whether it is a service business with no employees, one with 1–5 employees, or one with 6+ employees or any product business. An accountant-provided ratio is another option, as is a profit-and-loss method capped at 80%.
4. Count owner transfers in full. Transfers from the borrower’s own business into a personal account count at 100%. This is why a personal-statement file can sometimes outperform a business-statement file for a founder who pays themselves regularly.
5. Average it. Eligible deposits divide by the number of statement months to give one qualifying monthly income.
That figure then runs against debt-to-income and sizes the loan. The expense ratio is the main lever, and the lender sets it, not the borrower. Lendmire’s explainer How Income Is Calculated For A Bank Statement Loan? walks through the same flow in more detail.
Two other income paths exist. An asset allowance divides liquid assets by 36, 60, or 84 months to supplement income, on primary and second homes only. An assets-only path needs no debt-to-income test, but liquid U.S. assets must equal the loan plus closing costs plus sixty months of any net loss on other residential property. Retirement accounts count at 70%, or 80% at age 59½ and older. Business funds, gifts, and crypto never count.
The Ten-Year Timeline
A 10-year ARM is fixed for the first ten years. After that, the rate adjusts every six months for the rest of a typical 30-year term, so the adjustable phase lasts about twenty years, NerdWallet’s 10-year ARM explainer notes. Lenders write this as 10/6: ten years fixed, then a change every six months.
| Phase | What happens | What the borrower controls |
|---|---|---|
| Years 1–10 | Rate and payment are fixed | Pay down, sell, or refinance |
| First reset | Rate becomes index plus margin | Whether to act before it lands |
| Years 11–30 | Rate changes every six months | Little, apart from a refinance |
The new rate is the index plus the margin. The margin is fixed for the life of the loan. The index moves with the market. Most current non-QM adjustable loans use a SOFR-based index, and the New York Fed publishes SOFR Averages as backward-looking compounded averages over 30-, 90-, and 180-day periods. Super jumbo loans are not agency loans, so each program picks its own index. Ask which one applies before you commit.
Caps, Amortization, and the Worst Case
Caps limit how far the rate can move at the first adjustment, at each later adjustment, and over the life of the loan. They are usually written as three numbers. There is no standard cap structure for non-QM super jumbo loans, so treat any single set of cap numbers you see online as one lender’s choice, not a rule.
One misconception deserves a direct correction. Caps slow the climb; they do not stop it. A periodic cap can hold one adjustment below where the index has moved, and the unused portion can carry into later adjustments, depending on the note. A lifetime cap bounds the total increase, but the ceiling it creates can still sit far above the starting rate. When you model the post-reset payment, model it at the cap, not at the starting rate.
Amortization is the second structural variable, and it differs by program. Interest-only runs up to 85% LTV with a 700 credit floor on the portfolio program, as a 40-year term with a 10-year interest-only period. On the bank program, interest-only is limited to 60% LTV and to the 5- and 7-year fixed-period versions. A 10-year fixed-period adjustable on that program is fully amortizing. Interest-only ceilings apply to purchase and rate-term files and never raise a cash-out ceiling. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Why does this matter? A fully amortizing structure builds equity through the fixed period and enters the reset with a smaller balance. An interest-only structure carries a higher balance into the reset. Lendmire’s piece How to Use 40-Year Amortization on a Super Jumbo Bank Statement Loan covers that tradeoff in depth.
Where the General Rule Breaks
Business-purpose versus consumer-purpose. Investment property is generally treated as business-purpose, and loans to a business entity are exempt from some consumer protections under Regulation Z, 12 CFR 1026.3. An owner-occupied home is a consumer loan. For consumer loans, the ability-to-repay rule at 12 CFR 1026.43 requires qualifying at the greater of the fully indexed rate or any introductory rate. A business-purpose investment loan may not carry that mandate automatically, though lenders can still adopt conservative qualifying standards by policy. Whether a specific transaction is business-purpose is a compliance determination, so ask how your file will be qualified.
Reset notice. On consumer-purpose loans, servicers must give written notice well before the first adjusted payment is due, as the CFPB’s ARM handbook describes. Do not assume the same notice protections apply to a business-purpose loan.
12 versus 24 months. A 12-month window can distort seasonal or lumpy income. Whichever period captures the true pattern wins.
Property type. Warrantable condos run to 85% and non-warrantable to 80%. Second homes are one-unit only. Rural property runs to 80% on ten acres or less and never above $3,000,000. These limits are program-specific and tighten as the balance grows.
Is a 10-Year ARM the Right Structure?
The answer depends on the borrower’s exit plan, not on the documentation type.
| Fits well | Fits poorly |
|---|---|
| Expects to sell or refinance within a decade | Plans to hold for 20+ years with no refinance plan |
| Income grows with the business | Income is volatile and unlikely to absorb a higher payment |
| Wants payment stability for a long stretch | Cannot tolerate any payment uncertainty |
| Has equity and reserves to refinance later | Is relying on a refinance that depends on value holding |
The flip point is the refinance. A borrower who plans to refinance before the reset is betting on three things: that income documentation will still work, that reserves will still be in place, and that the property value will not have slipped enough to cut leverage. If any one of those fails, the reset arrives on schedule. A fixed-rate loan removes that dependency at the cost of whatever stability premium the market charges.
An investor weighing this against a property-income path has a real alternative. Bank statement qualification looks at the borrower’s income. A DSCR loan looks at the property’s rent against its payment. Super jumbo purchases can suit either, depending on how the investor documents income. For heavily leveraged holdings across multiple entities, the property-income lane sometimes fits better; for a founder with strong deposits and one large asset, the deposit lane often does.
Common Mistakes
- Modeling the starting payment forever. Model the post-reset payment at the cap.
- Assuming bank statement means light underwriting. Deposits are screened and discounted, not counted at face value.
- Treating the expense ratio as negotiable. The lender sets it from the business type and profit-and-loss data.
- Ignoring ownership percentage. If the borrower owns only part of the business, the lender applies that share.
- Forgetting the review step above $4,000,000. Every figure at that size is reviewed case by case before submission.
- Leaning on a refinance exit with thin reserves.
Documents to Gather
- Twelve or twenty-four consecutive months of statements for every account used for income, with all pages.
- A business ownership record showing at least 25% ownership, where business statements are used.
- An accountant letter or profit-and-loss statement if an accountant-provided expense ratio or the profit-and-loss method is in play.
- Statements for liquid assets, if an asset path is part of the file.
- Entity documents, if the borrowing entity is not an individual. Entity eligibility is a program matter.
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
Is a 10-year ARM riskier for a bank statement borrower?
The documentation and the rate structure are assessed separately, so the statement method does not itself add rate risk. What changes is the planning. Deposit-based income can swing year to year, which makes it more important to confirm that cash flow can absorb a higher payment after the reset.
Can a 10-year fixed period be interest-only?
Not on the bank portfolio program, where the 10-year fixed-period adjustable is fully amortizing and interest-only is limited to the 5- and 7-year versions at 60% LTV. The portfolio non-QM program offers a 40-year term with a 10-year interest-only period, up to 85% LTV with a 700 credit floor, through select wholesale programs and subject to full underwriting. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
How much can I borrow against a primary residence?
Through select wholesale programs, ceilings step down with size: 90% on a purchase 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. Above $4,000,000 each file is reviewed case by case.
Do transfers from my business count as income?
Transfers from your own business into a personal account count at 100% on a personal-statement file. Business-account deposits instead run through the expense ratio. Which route produces more qualifying income depends on how you pay yourself.
Can I refinance before the first reset?
Often, but it depends on income documentation, reserves, and the property’s value at that point. A refinance is a new underwriting, not a right. Borrowers who plan around one should keep reserves and documentation current.
