The Quick Read: Yes, but only on select programs. Through select wholesale programs, subject to full underwriting, a portfolio non-QM bank statement program pairs a 40-year term with a 10-year interest-only period, and “40-year” there means ten years of interest-only followed by thirty years of amortization, not forty years of paydown. The bank portfolio jumbo program does not work that way.
- A 40-year term is offered on one program type, not across the board.
- The usual build is a 10-year interest-only window plus a 30-year amortizing tail.
- Interest-only on the portfolio program reaches 85% LTV with a 700 credit floor, on purchase and rate-term files.
- The bank program allows interest-only through 5- and 7-year fixed-period adjustables, at up to 60% LTV.
- Every file above $4,000,000 is reviewed case by case before submission. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Nothing here is a commitment to lend. Terms vary by lender, borrower, property and loan size, and every file is underwritten individually.
What “40-Year” Actually Means
A 40-year term is a loan note that runs 480 months. On a super jumbo bank statement file, that usually breaks into two stages. The borrower pays interest only for the first 10 years. Then the loan converts to amortizing payments over the remaining 30 years.
Some structures amortize the full 480 months with no interest-only window. Both are called 40-year. The term sheet decides which one you have.
Scotsman Guide describes the same build for non-QM lending: a 40-year loan that allows interest-only payments for the first 10 years, then converts to a 30-year fixed-rate loan.
The misconception that causes the most bad files is that 40-year means 40 years of interest-only. It does not. The principal balance is untouched for the first ten years and then has to be repaid over the thirty that remain.
Why a 40-Year Term Is Always Non-QM
A 40-year loan can never be a qualified mortgage. The CFPB’s assessment of the ability-to-repay and QM rules says QM loans must be fully amortizing with terms no longer than 30 years. Loans that are ineligible for agency purchase, most often because of size, are generally non-QM too.
That is not a warning sign. Super jumbo size and a 40-year term both put a loan outside the agency channel, which is exactly where bank statement programs already live. Non-QM here means the lender writes its own guidelines, and those guidelines vary by program.
Investment property is a different category. Regulation Z exempts credit extended primarily for business purposes, and its commentary treats credit to acquire or maintain non-owner-occupied rental property as business purpose. That exemption does not apply to a primary residence, or to a second home the owner expects to occupy for more than 14 days in the coming year.
Which Structures Offer It
Across the wholesale network, the 40-year question has a program-by-program answer. Two programs carry super jumbo bank statement files, and they handle interest-only differently.
| Feature | Portfolio non-QM program | Bank portfolio program |
|---|---|---|
| Size reach | $300,000 to $6,000,000 | Overlaps to $6,000,000, then alone to $30,000,000 |
| 40-year term | Yes, with 10-year interest-only | Not the structure used |
| Interest-only | Up to 85% LTV, 700 credit floor | Up to 60% LTV |
| How interest-only is built | 10-year window inside the term | 5- and 7-year fixed-period ARMs |
| 10-year fixed option | n/a | Fully amortizing |
Every figure is a ceiling through select wholesale programs, subject to underwriting.
The bank program’s own ladder starts above $4,000,000 and runs to $30,000,000. At 65% to $5,000,000, 60% to $10,000,000 and 55% to $30,000,000, interest-only applies at 60% or the band’s ceiling, whichever is lower. Those figures are reviewed case by case.
So the honest answer to “does the 40-year term reach the biggest balances?” is no. The 40-year plus interest-only structure sits on the portfolio program, which tops out at $6,000,000. Above that, the borrower is on the bank program’s adjustable interest-only structures or a fully amortizing fixed option. Scoping the answer by program is more accurate than scoping it by size alone.
How the Lender Reviews Your File on Bank Statements
The term does not change how income is documented. A bank statement file is reviewed on documented income under the applicable program, subject to lender guidelines. Traditional personal-income documentation is not the starting point.
- Statement period. 12 or 24 consecutive months of personal or business statements. The bank program uses 12. Transaction histories never substitute.
- Business statements. The borrower needs at least 25% ownership.
- Expense ratio. Qualifying income is eligible deposits divided by the statement months, after an expense ratio. Fixed ratios run 20% for a service business with no employees, 40% for 1-5 employees, and 50% for 6+ employees or any product business. An accountant-provided ratio is an alternative, as is a profit-and-loss method capped at 80%.
- Owner transfers. Transfers from the borrower’s own business into a personal account count at 100%.
- Credit and DTI. Credit floor of 660 on the portfolio program, 680 on the bank program, 700 above the super-jumbo line. DTI up to 50%.
Scotsman Guide’s description of 12-to-24-month bank statement qualification with an expense factor matches that mechanic.
Here is where the term matters. Underwriters test a payment against income. Scotsman Guide reports that many lenders introduced a 40-year amortized loan for interest-only programs because qualifying on the higher post-interest-only payment of a 30-year loan with a 10-year interest-only option is hard. Stretching amortization over 30 remaining years rather than 20 makes that post-reset payment smaller. Practice differs by program. Some test the interest-only payment and others test the fully amortizing payment, so ask which one your program uses before you size the file.
What Changes at Super Jumbo Size
The term never overrides the size tier. As the balance rises, leverage generally falls, whichever term you pick.
Primary-residence purchase ceilings through select wholesale programs step down like this:
| Loan size | Purchase LTV ceiling | Credit for this leverage |
|---|---|---|
| $300K to $1M | 90% | 680+ |
| $1M to $1.5M | 85% | 700+ |
| $1.5M to $2M | 85% | 720+ |
| $2M to $3M | 80% | 720+ |
| $3M to $3.5M | 75% | 720+ |
| $3.5M to $4M | 75% | 760+ |
| $4M to $5M, on review | 65% | Set on review |
| $5M to $10M, on review | 60% | Set on review |
| $10M to $30M, on review | 55% | Set on review |
The credit figure is what that band’s top leverage needs, not a program floor. A lower score takes a lower leverage cell in the same band. Above $4,000,000 the bank portfolio program carries the ladder, every file is reviewed case by case, and the 700 credit floor applies above the super-jumbo line. That is why the table gives no score for those bands.
Second homes and investment property take their own ladders, which generally sit a few points lower at each size. Nothing above $1,000,000 reaches 90%.
Above $3,500,000 on a primary residence, and above $3,000,000 on a second home or investment property, the overlays tighten. The credit floor is 700, with a 0x30x24 housing history and 48 months of seasoning after any credit event. Borrowers must be U.S. citizens or permanent residents, with no non-occupant co-borrowers and no rural property. Cash-out proceeds cannot count toward reserves.
Reserves run 3 months to $500,000, 6 months to $1,500,000 and 9 months above that. Each additional financed property adds 2 months, to a 12-month maximum. First-time investors carry 12 months. Two appraisals are required above $2,000,000.
Cash-out is separate. It is unlimited at or below 60% LTV and capped at $1,500,000 cash in hand above 60% on the portfolio program. The bank program publishes no cap. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The Reset: What Happens When Interest-Only Ends
The payment rises at year 11 even if nothing else changes. Principal that sat untouched now amortizes over the remaining term. A 30-year note with a 10-year interest-only window leaves 20 years to repay. A 40-year note leaves 30, so the step-up is smaller. Smaller is not absent.
Plan the reset before the file goes in:
1. Model the post-reset payment, not just the interest-only payment.
2. Decide the exit: refinance, sell, or hold through the reset.
3. Check for prepayment terms on the program. They are common on investor loans and should not be assumed either way on a bank statement file.
4. Consider voluntary principal payments during the interest-only years if cash flow allows.
5. Confirm reserve requirements, since they sit on top of the loan regardless of structure. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
This is the part high-net-worth borrowers underweight. The balance does not fall for ten years, and lifetime interest cost runs higher than on a 30-year amortizing loan. Anyone assuming a long hold and rising values may accept that trade. Anyone planning to refinance should know that a refinance depends on value, credit and income at that point, not on today’s file.
Pros, Cons and Who It Fits
| Works well | Works poorly |
|---|---|
| Founders with lumpy deposits who want lower early obligations | Borrowers who cannot absorb the year-11 step-up |
| Buyers planning a sale or refinance within the window | Anyone expecting the balance to fall early |
| Files needing room under a 50% DTI cap | Files above $6,000,000, where the structure differs |
| Borrowers using deposits-based income | Borrowers wanting a fully amortizing fixed note |
Say an entertainer with strong deposits and thin tax-return income buys a $2,800,000 primary residence. At 80% purchase LTV with a 720+ credit score and interest-only, the early payment sits well below a 30-year amortizing structure. The trade is that the balance stays flat for a decade. That is fine for a borrower who expects to sell or refinance. It is a poor fit for one who cannot carry the reset. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Alternatives If a 40-Year Term Does Not Fit
- A 30-year fully amortizing loan. Higher payment, but the balance falls from day one.
- Bank program adjustables. 5- and 7-year fixed-period ARMs with interest-only to 60% LTV, or a fully amortizing 10-year fixed-period ARM.
- Asset paths. Asset allowance divides liquid assets by 36, 60 or 84 months, for primary and second homes at 80% maximum. Assets-only needs U.S. liquid assets equal to the loan plus closing costs, with no DTI.
- DSCR. For a rental, qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s DSCR loan vs bank statement loan comparison walks through when each path fits. Programs below 1.00 coverage exist through select lenders, with adjusted LTV and terms. Short-term rental files stop at $2,000,000, so the largest rentals use long-term rent coverage.
For the investor side, see the complete DSCR loans guide.
Key Terms Defined
Interest-only period: The stretch of the loan, typically the first 10 years here, when payments cover interest and the balance does not fall.
Amortization: Repaying principal through scheduled payments until the balance reaches zero.
Recast or reset: The point where interest-only ends and payments rise to include principal.
Qualifying payment: The payment the lender tests against income, which may be the interest-only or the fully amortizing amount, depending on the program.
Non-QM: A loan that falls outside qualified-mortgage rules, such as one with a term over 30 years.
Super jumbo: A balance well above standard jumbo limits, where overlays tighten and, above $4,000,000, files are reviewed case by case.
Frequently Asked Questions
Is there a balloon payment at the end of a 40-year term?
Not by structure. The usual build converts to a 30-year amortizing schedule after the interest-only period, so the balance is paid down over the remaining term. The term sheet confirms the exact schedule for your program.
Is a fully amortizing 40-year loan available?
Some structures amortize the full 480 months. Availability depends on the program, the size and the borrower. On the bank program, the 10-year fixed-period option is fully amortizing but is an adjustable, not a 40-year note.
Does interest-only mean the loan is adjustable?
No. On the portfolio program, interest-only sits inside a 40-year term. On the bank program, interest-only runs through 5- and 7-year fixed-period adjustables. The two are built differently.
Does a 40-year term change credit or reserve requirements?
The term itself does not. Credit minimums, reserves and leverage are set by program and loan size. The 700 floor applies above the super-jumbo line regardless of term, subject to lender guidelines and a full file review.
Can a 40-year term be used on a cash-out file?
Cash-out has its own ladder. On a primary residence, the best cash-out ceiling is 80%. Above 60% LTV the portfolio program caps cash in hand at $1,500,000. Terms depend on the lender’s guidelines, the property, the leverage, and the credit profile.
