The Quick Read: A 40-year super jumbo bank statement loan is a non-QM mortgage on a very large balance that is reviewed around twelve or twenty-four months of bank deposits rather than traditional personal-income documentation, usually pairs a 40-year term with a ten-year interest-only window, and then resets into principal-and-interest payments for the remaining thirty years. It is available through select wholesale programs, subject to full underwriting and lender guidelines. This is not a commitment to lend.
- Income: deposits, minus an expense ratio on business accounts, become qualifying income. Your other debts still count.
- Term: the 40-year note often means ten interest-only years, then thirty amortizing years. Some 40-year products amortize the whole way, so the term sheet decides.
- Size: leverage steps down as the balance climbs, and every file above $4,000,000 is reviewed case by case before submission.
- Reset: the payment steps up when the interest-only period ends. Model that number, not just the starting one.
- Fit: it suits high earners whose traditional personal-income documentation understates cash flow. It is a poor fit when the property’s rent is the stronger story.
What the Label Actually Stacks Together
The name combines three separate features. Each one answers a different question, and mixing them up is a common source of confusion.
Super jumbo describes loan size. It means a balance above the conforming and ordinary jumbo range. Lenders define the threshold themselves, so the term has no single dollar line. Through the wholesale programs Lendmire places files with, balances run from $300,000 to $30,000,000.
Bank statement describes how income is documented. You show deposit history instead of W-2s or returns.
40-year describes the note term. It is the feature that changes your monthly carry and your long-run cost.
Jumbo size and non-QM status are separate ideas. A jumbo loan can be fully documented. A bank statement loan can be modest in size. The combination appears when a borrower has a large balance and income that does not show cleanly on a return.
Why Two Programs Sit Behind the Same Name
Lendmire is a mortgage broker. It shops this product across wholesale lenders instead of originating it. Two program types matter here.
The first is a portfolio non-QM bank statement program. It carries files from $300,000 to $6,000,000 and offers the 40-year term with a ten-year interest-only period. Interest-only runs to 85% LTV with a 700 credit floor, through select wholesale programs, subject to underwriting. That figure is the ceiling of the interest-only structure on purchase and rate-and-term files. It does not raise any cash-out limit, and the size ladder below still applies. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The second is a bank portfolio jumbo program. It uses twelve months of statements and carries files up to $30,000,000. Its size ladder begins above $4,000,000 and overlaps the portfolio program up to $6,000,000. Above $6,000,000 it stands alone. Its interest-only options are 5- and 7-year fixed-period adjustables at up to 60% LTV, and a 10-year fixed-period adjustable is fully amortizing. This program does not offer the 40-year interest-only note. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
So a “40-year” request routes mostly to the portfolio program. The bank program becomes the answer when the balance outgrows it.
How Underwriting Treats Your Deposits, Step by Step
Underwriting follows the same sequence on most files. Walking through it shows where the numbers come from.
Step 1: Choose the statement window. You provide 12 or 24 consecutive months. The portfolio program accepts either. The bank program uses 12. Statements must be consecutive, and transaction histories never substitute for them.
Step 2: Choose personal or business accounts. Business statements require at least 25% ownership of the business. Personal statements work when deposits trace to your professional or business activity.
Step 3: Clean the deposits. Underwriters keep income-related deposits. They strip out refunds, loan proceeds, peer-to-peer payments and transfers between your own accounts. Large one-time spikes need an invoice or contract. One exception helps founders: transfers from your own business into your personal account count at 100%.
Step 4: Apply the expense ratio. On business statements, the lender assumes part of each deposit went to operating costs. Across the network, the fixed ratios are:
- 20% for a service business with no employees
- 40% for a business with one to five employees
- 50% for six or more employees, or any product business
An accountant-provided ratio is also accepted. A profit-and-loss method exists too, capped at 80%.
Step 5: Run the formula. Eligible deposits divided by the number of statement months, multiplied by one minus the expense ratio, gives monthly qualifying income. The ratio is set by business type and documentation, not by negotiation.
Step 6: Count your debts. This is the key contrast with a rental-based loan. The file is underwritten to your personal income and obligations, with debt-to-income up to 50%. A bank statement loan rewards strong personal cash flow. It does not reward a strong rent roll. Investors whose property income carries the file belong in a different lane, covered in Lendmire’s complete DSCR loans guide.
Why a 40-Year Term Is Always Non-QM
A qualified mortgage cannot carry a term longer than 30 years. The federal rule text in 12 CFR 1026.43 says the term must not exceed 30 years. Interest-only periods and principal deferral are also outside that safe harbor.
So a 40-year note is non-QM by definition. That label does not mean unregulated or loosely underwritten. Reg Z’s ability-to-repay standard still requires lenders to weigh debt-to-income or residual income, credit history and other factors. The standard does not say how much income supports a given debt level. Each lender sets that bar.
Non-QM also means there are no caps on closing costs and fees, as Scotsman Guide notes. That trade-off is real, so compare loan estimates line by line.
One more point. Investment-property loans made for business purposes are generally reviewed differently from owner-occupied mortgages. That is part of why 40-year and interest-only terms show up more often on investor files.
The Two Common Builds
Not every 40-year loan works the same way. Before you compare offers, find out which build you are looking at.
| Feature | Interest-only, then amortizing | Fully amortizing 40-year |
|---|---|---|
| Early payments | Interest only | Interest plus principal |
| Principal paid early | None | Small amounts |
| Reset | Yes, at the end of the IO period | None |
| Equity build | Slow, from appreciation or paydown | Slow, but steady |
| What to verify | IO length, tested payment | Prepayment terms |
The interest-only build is the more common one. Scotsman Guide describes it as interest-only for up to ten years, after which the borrower repays principal and interest or refinances. Scotsman Guide also reports these loans are still relatively uncommon and can be hard to find. That is where a broker with wholesale access earns its place.
Which Payment Gets Tested?
The tested payment is the most important underwriting question on this structure. Programs differ, and a few of the answers carry real consequences.
| Tested on | What it means for you |
|---|---|
| Interest-only payment | Easier qualifying, with the biggest reset gap |
| Post-reset payment | Tighter qualifying, with less payment shock later |
The conservative approach, per Scotsman Guide’s discussion of interest-only underwriting, is to qualify on the higher payment that begins in year eleven. Many lenders then introduced 40-year amortized interest-only products, because the longer amortization keeps the post-reset payment lower and lets more borrowers qualify.
Ask for the tested payment in writing before you commit. A longer term does not create extra qualifying room by itself. Interest-only does not either, when the lender tests the amortized payment.
What the Reset Looks Like
Consider a borrower on a ten-year interest-only window. For ten years the payment covers interest alone and the balance never moves. When the window ends, principal amortizes over the remaining thirty years. Because nothing was paid down, the new payment roughly matches what a 30-year amortizing loan on the full balance would have required from day one. The step-up is real, and it lands whether or not your income grew.
You have four ways to meet it:
1. Refinance. This works only if your credit, income and the property’s value still support a new loan. Nothing guarantees that.
2. Sell. The interest-only years suit a planned exit.
3. Pay down early. Principal prepayments during the interest-only years reduce the balance that resets.
4. Absorb the step-up. This works when income has grown or other debts have fallen.
The first option carries the most risk, because it depends on future conditions. Lenders and loan officers cannot promise a refinance outcome. Stress-test the reset against flat income before you sign.
What the Longer Term Costs
A 40-year term mostly stretches interest. Scotsman Guide’s own framing is that the borrower pays more interest over the loan’s life and builds equity more slowly. During interest-only years, equity grows only if the property appreciates or you prepay.
The structure pays off in specific situations. It fits a high earner with uneven cash flow who wants a lower early carry. It suits a buyer with a defined exit or a planned refinance. It also fits an investor who would rather keep cash deployed elsewhere. For a borrower who plans to hold for decades and wants steady equity, a fully amortizing path usually costs less over time.
How Super Jumbo Size Changes the Terms
Size drives nearly every other term. As the balance climbs, leverage falls, credit floors rise and reserves grow. Every figure below is a ceiling through select wholesale programs, subject to underwriting.
On a primary residence purchase, leverage steps down roughly like this:
| Loan size | Maximum LTV, primary residence purchase |
|---|---|
| To $1,000,000 | 90% |
| To $2,000,000 | 85% |
| To $3,000,000 | 80% |
| To $4,000,000 | 75% at the top credit tier |
| Above $4,000,000 | Case-by-case review; bank program ladder applies |
Second homes and investment properties run about five points lower at every size. The bank program’s ladder runs 65% to $5,000,000, 60% to $10,000,000 and 55% to $30,000,000, always on review above $4,000,000. Nothing above $1,000,000 gets 90%.
Credit follows the same pattern. The portfolio program’s floor is 660. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Above the super-jumbo line, the floor is 700.
Extra overlays apply above $3,500,000 on a primary residence and above $3,000,000 on a second home or investment property:
- 700 credit floor
- 0x30x24 housing history
- 48-month seasoning after any credit event
- U.S. citizens and permanent residents only
- no non-occupant co-borrowers
- no rural property, and ten acres maximum
- cash-out proceeds cannot satisfy reserves
Reserves run 3 months to $500,000, 6 months to $1,500,000 and 9 months above that. Add 2 months for each additional financed property, to a 12-month maximum. First-time investors need 12 months.
Purchase, Rate-and-Term or Cash-Out?
| Transaction | What changes |
|---|---|
| Purchase | Highest leverage on the ladder |
| Rate-and-term | Similar leverage; one tier lower at the top end |
| Cash-out | Lower ceilings; cash-in-hand capped above 60% LTV |
On a primary residence, cash-out tops out at 80% LTV up to $1,500,000 and steps down from there. Cash-out is unlimited at or below 60% LTV. Above 60%, the portfolio program caps cash-in-hand at $1,500,000. The bank program has no published cap. Cash-out proceeds cannot count toward reserves on super-jumbo files. Interest-only never lifts a cash-out ceiling. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Edge Cases Where the Rule Breaks
A 40-year loan that is not interest-only. Some products amortize across the full term. Others pair interest-only with an adjustable structure and a shorter fixed period. The term sheet is the only reliable guide.
Owner-occupied versus investment. The same structure appears on primary residences and investment properties, but the leverage and credit columns differ by occupancy. Second homes are limited to one unit. Multi-unit properties of two to four units can reach 85% under the right program.
Condos and special property types. Warrantable condos run up to 85%. Non-warrantable condos run up to 80%. Condotels run at 75% on a purchase and 65% on a cash-out, and 50% on the bank program.
Texas home-equity loans. A Texas 50(a)(6) loan takes a 5-point LTV reduction and stops at $3,000,000 on the portfolio program.
Thin or irregular deposits. If the deposit history is volatile, a profit-and-loss method or an asset path may work better. These alternatives are covered next.
When Assets or Rent Fit Better
Bank statements are one of three documentation paths. Pick the one that matches where your strength sits.
| Path | What qualifies you |
|---|---|
| Bank statements | Your deposit cash flow, after an expense ratio |
| Asset allowance or assets-only | Liquid assets |
| Rental-income (DSCR) loan | The property’s rent covering its payment |
Asset allowance divides liquid assets by 36, 60 or 84 months to create supplemental income. Use 36 months when DTI is at or below 60%, 60 months when it is above, and 84 months for standalone use or any loan above $3,500,000. It applies to primary and second homes, at 80% maximum.
Assets-only qualifies with no DTI at all. It requires liquid U.S. assets equal to 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 over. Business funds, gifts, most trusts, unvested stock and cryptocurrency never count.
A rental-based loan fits when the property’s income carries the file and you want your personal debts out of the picture. That loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. For a pure rental purchase, it is often the cleaner lane.
Key Terms Defined
Super jumbo: a loan balance above the ordinary jumbo range, with a threshold each lender sets on its own.
Bank statement loan: a mortgage that is reviewed around deposit history instead of traditional personal-income documentation.
Interest-only period: the stretch, often ten years, when payments cover interest and the balance stays flat.
Amortization: the schedule that pays the balance down through regular principal payments.
Reset: the payment step-up that happens when the interest-only period ends.
Expense ratio: the share of business deposits the lender assumes went to operating costs.
Non-QM: a mortgage that falls outside the qualified-mortgage box, usually because of its term, structure or documentation.
Who It Fits, and the Steps to Apply
This structure fits founders, physicians, attorneys, entertainers and investors whose write-offs shrink their reported income. It fits people with strong personal cash flow and a large balance. It fits buyers who value a lower early carry.
It is a weaker fit if you need the highest possible equity build, if your debts already crowd the 50% DTI line, or if you are counting on a refinance that conditions may not allow. It is also a poor fit if the file only works at leverage the size ladder does not offer.
Preparation is straightforward:
1. Gather 12 or 24 consecutive months of statements.
2. Separate business deposits from personal ones, and flag unusual spikes.
3. Confirm ownership percentage and business type for the expense ratio.
4. List liquid assets and every financed property.
5. Decide whether purchase, rate-and-term or cash-out is the goal.
6. Ask for the tested payment and the reset schedule in writing.
Consumer lending is licensed in 16 states: AL, CA, CO, FL, GA, IN, MI, MT, NM, NC, OH, PA, TN, TX, VA and WA. A property outside that list calls for a scope conversation first. Lendmire’s complete guide to 40-year super jumbo bank statement loans gives the wider program picture.
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 40-year loan always mean ten interest-only years?
No. Ten interest-only years followed by thirty amortizing years is the most common build, and the portfolio non-QM program follows it. Other products amortize across all 40 years, and some pair interest-only with an adjustable structure and a shorter fixed period. The term sheet shows which one you have.
Can I make extra principal payments during the interest-only period?
Often yes, but it depends on the program and any prepayment terms. Paying down principal early lowers the balance that resets. Confirm prepayment terms before relying on this as your reset plan.
Do big deposits from my own business count as income?
Transfers from your business into your personal account count in full on this program. Refunds, loan proceeds, peer-to-peer payments and transfers between your own accounts do not. Large spikes need documentation, such as an invoice or contract.
What credit score do I need?
The portfolio program’s floor is 660. Above the super-jumbo line, 700 is the floor. Those thresholds sit at $3,500,000 on a primary residence and $3,000,000 on a second home or investment property. Higher leverage tiers ask for higher scores, with some tiers at 720 or 760.
Is the qualifying payment the interest-only payment?
It depends on the program. Some programs test the interest-only payment, and others test the higher post-reset payment. Ask which one applies before you commit, because it changes how much loan you qualify for and how large the reset gap is.

The reset is the one date on this loan that you can see coming from day one, so the strongest files plan for it before closing instead of at year ten.
