The Quick Read: Usually 700 or higher: that is the floor once a file crosses into super-jumbo territory or uses the 40-year interest-only structure, while a standard bank statement file can start at a 660 floor through select wholesale programs, subject to full underwriting and lender guidelines. The score also sets how much you can borrow against the property, not how much income you show.
- The 660 floor applies to the portfolio non-QM program (a lender-held program outside agency rules). Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review.
- Interest-only on the 40-year structure needs 700 or higher on the portfolio program.
- Bigger loans need higher scores for top leverage: 680+ at the low end, 720+ in the middle, 760+ near $4 million on a primary residence.
- Above $4,000,000, every file is reviewed case by case before submission.
- Deposits set your income. Credit sets your leverage.
Key Terms Defined
Super jumbo means a loan large enough that programs add stricter overlays. In this network that line sits above $3,500,000 on a primary residence and above $3,000,000 on a second home or investment property.
Bank statement loan means a mortgage that is reviewed around documented deposits, 12 or 24 months of them, instead of traditional personal-income documentation.
Non-QM means a loan that sits outside the standard “qualified mortgage” box, so each program writes its own credit rules.
Interest-only period means a stretch, here 10 years, when the payment covers interest and no principal.
Middle score means the median of your three bureau scores, which many programs use as the score that counts.
Reserves means liquid cash left over after closing, measured in months of housing payments.
What Score Does Each Loan Size Need?
Bigger loans need higher scores to reach top leverage. Through select wholesale programs, a primary-residence purchase asks for 680+ at the low end, 720+ through the middle, and 760+ just under $4 million. The table shows the ceilings, subject to underwriting.
| Loan size (primary residence) | Max purchase LTV | Credit for this leverage |
|---|---|---|
| $300K–$1M | 90% | 680+ |
| $1M–$1.5M | 85% | 700+ |
| $1.5M–$2M | 85% | 720+ |
| $2M–$3M | 80% | 720+ |
| $3M–$3.5M | 75% | 720+ |
| $3.5M–$4M | 75% | 760+ |
| $4M–$5M | 65%, case by case | 680+ (bank program, on review) |
LTV, or loan-to-value, is the loan as a share of the property’s value. Second homes and investment property take their own ladders, which run lower at most sizes. Above $4,000,000, the figures are reviewed case by case before submission, so treat the last row as a starting point for review, not a promise. That ladder belongs to the bank portfolio program, which begins above $4,000,000 and carries twelve-month-statement files to $30,000,000. It is a separate program with its own size ladder, so the best cell can step back up at a larger size.
Here is the catch most people miss. The 660 floor is the door, not the best room in the house. A 660 file clears the portfolio program’s minimum. It does not reach the 90% cell at the bottom of the ladder. Each band has its own score for its top leverage, and missing it trims the LTV rather than ending the conversation.
Does the 40-Year Term Raise the Bar?
The term itself matters less than the structure inside it. A 40-year loan is non-QM by definition. The federal consumer-finance regulator’s General qualified-mortgage rule excludes interest-only features and terms over 30 years, so no federal credit-score minimum applies to it. The floor comes from each program’s own guidelines.
Non-QM does not mean unregulated. The lender must still make a reasonable, good-faith determination that you can repay, which is why programs lean on score, reserves, and housing history.
In practice, here is how it breaks down on the portfolio program:
- 40-year with a 10-year interest-only period: 700 or higher, with interest-only qualification up to 85% LTV on purchase and rate-term files. Cash-out ceilings are lower and come from the ladder.
- Standard bank statement file: a 660 floor, with top-tier leverage needing more.
- Bank program interest-only: limited to 60% LTV through 5- and 7-year fixed-period adjustables. Its 10-year fixed-period option is fully amortizing. Exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Scotsman Guide describes this 40-year design as 10 interest-only years, then a 30-year fixed schedule. Plenty of borrowers read 40-year as 40 years of paydown. It isn’t.
Non-QM lenders also commonly qualify you on the higher payment that starts after the interest-only period ends. Plan for the step-up, not the teaser.
How Is the Score Read, and What Else Gets Checked?
Many programs pull three bureau scores and work from the middle one. Confirm which score a specific program uses before you shop. The score is only one gate among several. A file is also reviewed on:
- Housing history: super-jumbo files require 0x30x24, meaning no 30-day late in 24 months.
- Credit events: 48 months of seasoning after any bankruptcy, foreclosure, or similar event.
- Reserves: 3 months up to $500,000, 6 months up to $1,500,000, and 9 months above. Add 2 months per additional financed property, to a 12-month maximum. First-time investors need 12.
- Debt-to-income: up to 50%, because a bank statement file is reviewed around personal income.
- Overlays: U.S. citizens and permanent residents, no non-occupant co-borrowers, no rural property, and ten acres maximum. On cash-out, the proceeds can’t count toward reserves.
A clean payment history can matter as much as a few score points. A 740 with a recent late payment can look worse on paper than a 715 with a spotless record.
How Bank Statement Income Meets Your Credit File
Strong deposits don’t rescue a weak score. They solve a different problem. The lender totals 12 or 24 consecutive months of personal or business deposits and divides by the number of months. Business statements apply an expense ratio:
- 20% for a service business with no employees
- 40% for 1 to 5 employees
- 50% for 6 or more employees or any product business
- An accountant-provided ratio, or a profit-and-loss method capped at 80%
Business statements require at least 25% ownership. Transfers from your own business into your personal account count in full. Statements must be consecutive; transaction histories don’t substitute.
Think of it as two keys. Deposits turn the income lock. Credit turns the leverage lock. Founders, physicians, attorneys, and entertainers whose returns understate income often have the first key and need to check the second.
Three Borrower Pictures
These are modeled situations, not approvals.
Comfortably above the line. A founder with a 770 middle score wants a primary residence in the $3.5M–$4M band. The 760+ tier is within reach, so the top purchase ceiling of 75% is on the table, subject to reserves, housing history, and underwriting.
Near the line. A physician at 690 buys a primary residence at the low end of the ladder. A 680+ score reaches the top purchase tier at loan sizes up to $1M. Push that same file past $1M and the tier wants 700+, so leverage steps back. Raising the score 10 points before applying would change that picture. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Below the line. An attorney at 655 wants the interest-only structure. The 40-year interest-only design needs 700 or higher, and 655 sits under even the 660 portfolio floor. A different structure, a different program, or a few months of credit repair becomes the conversation.
What If You’re Below the Line?
You have options, and none of them is wishful thinking.
1. Borrow less. Lower balances reach top leverage at lower scores. The ladder rewards smaller loans.
2. Put more down. A lower LTV can help a file that sits near a floor, subject to program review.
3. Switch the qualification path. Asset allowance divides liquid assets by 36, 60, or 84 months. Assets-only needs liquid U.S. assets equal to the loan plus closing costs, with no DTI test. Retirement accounts count at 70%, or 80% at age 59½ and older. Business funds, gifts, and cryptocurrency never count.
4. Use the property’s income. On an investment property, a DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Lendmire’s complete DSCR loans guide explains how.
5. Repair first. Pay down revolving balances, avoid new credit lines, and confirm the report is accurate. Many borrowers lose a tier over one correctable item.
Remember too that programs change and every file is underwritten individually.
Is 40 Years Worth It? (The Trade-Offs)
It depends on your plan. The structure lowers the early payment because you pay interest only for the first 10 years. It doesn’t build equity during that stretch, and total interest over the life of the loan runs higher. Scotsman Guide notes that the 40-year loan is still uncommon, so fewer lenders offer it.
A borrower with lumpy income and a plan to sell or refinance within the interest-only window may find it useful. A borrower who wants steady paydown may not. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Can I get a 40-year super jumbo bank statement loan with a 660 score?
Not on the interest-only structure, which needs 700 or higher on the portfolio program. A 660 file may clear that program’s floor for a standard bank statement loan, but top leverage generally needs more. Super-jumbo overlays above the size lines raise the floor to 700. Every file is underwritten individually.
Does a longer term make the score requirement easier?
No. A 40-year loan is non-QM, so each program sets its own floor, and the interest-only version asks for more, not less. The longer term lowers the early payment; it does not loosen the credit review.
Do bank statements make my credit score less important?
No. Deposits set qualifying income, but credit still decides eligibility and how much you can borrow against the property. Lenders also review reserves, housing history, and DTI.
Does the score requirement change for second homes and investment properties?
Yes. Each occupancy has its own leverage ladder, and the super-jumbo overlays begin at a lower balance: $3,000,000 versus $3,500,000 on a primary residence. Some size bands also carry different score tiers by occupancy.
What happens above $4,000,000?
Every file is reviewed case by case before submission. The bank portfolio program’s own ladder applies there. Never assume a flat maximum.
