The Quick Read: It depends on loan size, and the 40-year term does not change the count. Through select wholesale programs, subject to full underwriting, reserves typically run 3, 6, or 9 months of the full housing payment, rising with the balance. Extra financed properties and first-time-investor status push the number higher.
- 3 months on balances up to $500,000.
- 6 months above that, up to $1,500,000.
- 9 months above $1,500,000.
- Plus 2 months for each additional financed property, capped at 12 months total.
- First-time investors typically need 12 months.
Above $4,000,000, every file is reviewed case by case before submission, so treat the ladder as a starting point there, not a promise.
How Are Reserve Months Set on a Bank Statement Loan?
The count comes from the program, not from a federal formula. Across the wholesale network Lendmire works with, the ladder is tied to loan size: 3 months, then 6, then 9. Bigger balance, bigger cushion. The lender is asking how long you could carry the property if your deposits dried up.
Lendmire is a broker. It shops these files across multiple wholesale programs and does not lend itself. That matters here because reserve ladders differ from program to program. Some lenders want 12 months on large files. Others stop at 6. Anyone who quotes you “the market number” is quoting one lender.
Here is the ladder most files follow through select wholesale programs:
| Loan size | Base reserves | Add-ons |
|---|---|---|
| Up to $500,000 | 3 months | +2 per extra financed property |
| $500,001 to $1,500,000 | 6 months | +2 per extra financed property |
| Above $1,500,000 | 9 months | +2 per extra financed property |
| Any size, first-time investor | 12 months | Already at the cap |
The add-ons stop at 12 months total. So a borrower on the 9-month tier with two other financed properties hits 13 on paper and lands at the 12-month cap.
A portfolio non-QM program carries bank statement files to $6,000,000. Above $4,000,000 everything gets reviewed case by case, including reserves.
Does the 40-Year Term Change the Reserve Count?
No. The term changes the payment that the reserve months get multiplied by. It does not change the number of months.
Think of it as two separate dials. One dial is months: 3, 6, 9, or 12. The other is the monthly housing payment. A longer term or an interest-only period lowers that payment in the early years. Same months, smaller payment, smaller reserve dollars to document.
The 40-year loan is usually built as a 10-year interest-only period followed by a 30-year amortizing tail, though some programs amortize across all 40 years. Scotsman Guide describes the interest-only version as paying interest only for up to 10 years, after which the borrower repays principal and interest or refinances. The same article notes that the borrower pays more interest over the life of the loan and builds equity more slowly.
Here is the comparison that trips people up:
| Factor | Reserve count | Reserve dollars |
|---|---|---|
| 40-year term vs. 30-year | Same months | Lower payment, so lower dollars |
| Interest-only period | Same months | Depends on the program’s test payment |
| Larger loan size | More months | More dollars, twice over |
The honest wrinkle is which payment the program uses for the reserve multiple. Some programs multiply by the interest-only payment. Others test against the higher payment that starts after the interest-only period. Ask for this in writing before you plan your liquidity. It can swing the cash you need to hold by a wide margin.
What the term does not touch
Credit minimums, leverage caps, and seasoning stay the same. A 40-year structure is not a loophole. On the portfolio program, the interest-only structure tops out at 85% LTV on purchase and no-cash-out refinance files, with a 700 credit floor, and the size ladder still applies on top of that. Above $4,000,000 that ceiling comes down and the file is reviewed case by case. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
How Do You Count Reserves? A Walk-Through in Months
Reserves are what is left after closing, measured in months of the full payment. The full payment means principal, interest, taxes, insurance, and association dues, often shortened to PITIA.
Three steps:
1. Subtract funds to close. Down payment and closing costs come out first. Only what remains after closing counts.
2. Find your required months. Start with the size tier, add 2 months per additional financed property, and stop at 12.
3. Multiply by the program’s payment. The result is the cash cushion you must document in eligible assets.
Run the logic on a modeled borrower. Say you buy a property in the middle tier, 6 months, and you already carry a financed rental and a financed second home. That is 6 plus 2 plus 2, or 10 months. If you were a first-time investor on the same deal, the answer jumps to 12. If the loan sat in the top tier at 9 months with the same two properties, you would reach 13 and the cap would cut it to 12.
Notice what is missing. No dollar figures. That is deliberate, because the payment depends on the loan, the term structure, and the program’s test. Your broker can price the months once the structure is set.
Reserves and Income Are Separate Tests
Strong deposits do not shrink your reserve requirement. Big reserves do not rescue thin deposits. Underwriting runs two tests side by side. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
The income test uses 12 or 24 consecutive months of personal or business bank statements. The bank portfolio program uses 12. Qualifying income is eligible deposits divided by the statement months, after an expense ratio. Fixed expense ratios are commonly tiered by business type and size, with a lower ratio for a service business with no employees and higher ratios as headcount grows or for a product business. An accountant-provided ratio is also possible, and a profit-and-loss method is capped at a set percentage of deposits. Transfers from your own business into a personal account may count in full, depending on the program.
The reserve test uses your most recent asset statements. Scotsman Guide describes the standard setup this way: a self-employed borrower with no W-2 supplies 12 to 24 months of statements, and income comes from an expense factor or a profit-and-loss statement prepared by a tax professional.
Bank statements do not mean a lighter review. Credit, assets, property, and the source of deposits all get reviewed. Debt-to-income can run up to 50% on the network’s programs. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. Above the super jumbo line, the minimum credit score rises to 700.
That line sits at $3,500,000 on a primary residence and $3,000,000 on a second home or investment property. Past it, extra overlays apply: a 0x30x24 housing history, 48 months of seasoning after any credit event, and no rural property. Cash-out proceeds also cannot satisfy reserves at that size. Hold that thought for the next section.
What Counts as a Reserve Asset, and What Doesn’t
Cash counts most cleanly. Everything else gets discounted or excluded, and the treatment differs by lender.
| Asset | Typical treatment |
|---|---|
| Checking and savings | Counts in full, with a paper trail |
| Brokerage accounts | Generally counts, lender by lender |
| Retirement accounts | Discounted; 70% on asset paths (80% at 59.5+) |
| Business funds | Treated separately; do not assume they count |
| Gifts, unvested stock, crypto | Do not count |
Those figures come from the asset-qualification paths Lendmire sees across the network. On those paths, retirement accounts count at 70%, or 80% for borrowers 59.5 and older. Business funds, gifts, trusts other than a revocable living trust, unvested stock, and cryptocurrency never count there. Most files treat reserves the same way, but confirm with your program.
Business money is where high earners get surprised. Your company’s balance can look like personal liquidity, and underwriting often disagrees. Lendmire’s piece How to Use Business Reserves on a Super Jumbo Bank Statement Loan walks through that treatment in detail.
Cash-out proceeds are a trap
If you refinance to pull cash out, you may be tempted to count that cash as your reserves. Above the super jumbo line, you cannot. Cash-out proceeds do not satisfy reserves on files above $3,500,000 on a primary residence, or above $3,000,000 on a second home or investment property. Plan your cushion from assets you already hold, outside the transaction.
Recently deposited funds usually need a paper trail too. A large transfer that appears the week before application invites questions. Seasoned money is easier money.
When the Number Moves Up
Reserves rise for specific reasons. Here are the main ones:
- More financed properties. Each one adds 2 months, up to the 12-month cap. Your next purchase can raise the requirement on this one.
- First-time investor status. Typically 12 months from the start.
- Occupancy. Second homes and investment property run about five points lower on leverage at every size than a primary residence, and firmer reserve expectations often come with them.
- Loan size above $4,000,000. Case-by-case review means the published ladder may not apply.
- Short-term rental collateral. Lenders can weigh reserves differently when the property earns nightly income.
Here is how a broker thinks about it. A file with big deposits and thin liquidity is a weaker file than the reverse. Many investors arrive with strong monthly deposits and most of their net worth tied up in property. The reserve test is where that shows up.
Does a Bank Statement Loan or a DSCR Loan Need More Reserves?
They use different logic, so do not borrow numbers from one for the other. A bank statement loan is reviewed on deposits and ignores traditional personal-income documentation. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, and ignores personal income.
DSCR programs carry their own reserve rules, often counted on the subject property and tested on the interest-only payment when the loan is interest-only. The 3/6/9 ladder above belongs to bank statement files. If your personal income is strong on paper but the rent barely covers the payment, a bank statement structure can fit better. If the rent is strong and your personal income is messy, DSCR may fit better. Lendmire’s complete DSCR loans guide lays out how that second path works.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Why Is the Regulatory Frame Silent on Reserves?
No federal rule sets a reserve number for this loan. The CFPB’s ability-to-repay compliance guide requires lenders to consider debt-to-income or residual income. It sets no threshold for either and has no reserve-month requirement.
The Federal Register text of the General QM rule names cash reserves as one factor that can bear on repayment ability. It also treats interest-only and limited-documentation features as non-QM. A 40-year interest-only bank statement loan has both.
So reserves are a lender risk-management choice. That is why the numbers vary, and why you should read the term sheet instead of a headline.
Key Terms Defined
Reserves: Liquid assets you still hold after paying the down payment and closing costs.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing payment.
Super jumbo: A loan above the standard jumbo line, where lenders add overlays. The line sits at $3,500,000 on a primary residence and $3,000,000 on a second home or investment property.
Bank statement loan: A non-QM loan that is reviewed around 12 or 24 months of deposits instead of traditional personal-income documentation.
Interest-only period: A stretch, usually 10 years here, when you pay interest and no principal.
Seasoning: The time funds have sat in your account, or the wait after a credit event.
Planning Beyond the Minimum
The lender’s number is a floor. It is not a plan.
Self-employed income swings. A strong deposit year can be followed by a lean one. A 40-year interest-only loan also resets. After the interest-only period, the payment rises, and your reserves were sized to the lower one. Test the post-reset payment before you sign.
A few habits help:
- Keep reserves in your own name, in accounts with a clean statement history.
- Do not count the same dollars twice: down payment, closing costs, and reserves are three buckets.
- Add up your financed properties before choosing a purchase. Each one adds months.
- Ask the broker which payment the program uses for the reserve multiple.
- Budget extra for closing costs. Scotsman Guide notes a 40-year mortgage is non-QM, so no caps apply to closing costs and fees.
Availability is also a real constraint. The same Scotsman Guide piece says originators may struggle to find a lender offering a 40-year loan, since it remains relatively uncommon. That is one reason to shop across programs. For a closer look at the structure itself, see Lendmire’s article How to Use 40-Year Amortization on a Super Jumbo Bank Statement Loan.
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
How many months of reserves does a super jumbo bank statement loan need?
Usually 3, 6, or 9 months of the full housing payment, depending on loan size, through select wholesale programs. Add 2 months per additional financed property, up to 12. Above $4,000,000, files are reviewed case by case.
Does a 40-year term lower the reserve requirement?
It lowers the payment the months multiply against, not the months themselves. You may need less cash in dollars, but you still need the same count. Confirm whether the program uses the interest-only payment or the post-reset payment. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Can cash-out proceeds count as reserves?
Not above the super jumbo line. That means above $3,500,000 on a primary residence and above $3,000,000 on a second home or investment property. Below those sizes, treatment depends on the program, so plan on assets you already hold.
Do retirement funds count?
Often at a discount. On the asset-qualification paths, retirement accounts count at 70%, or 80% at age 59.5 and older. Gifts, unvested stock, and cryptocurrency do not count.
What if I am a first-time investor?
Expect 12 months on most files. Your first financed investment property has no track record behind it, so lenders ask for the full cushion.
What if I am short on reserves?
Options include a smaller loan, a larger down payment from other sources, seasoning additional assets, or a different program with a lower count. Each changes leverage or structure, so run the options with a broker before you commit.
Next Step
If you are financing a high-balance property on business or personal bank statements and want to see how the numbers work, Lendmire can help you compare super jumbo bank statement loan options based on your deposits, the property, credit profile, leverage, and your goals. Consumer mortgage lending is licensed in 16 states, so availability depends on where the property sits. Every parameter here is a typical range through select wholesale programs, subject to full underwriting, and nothing is a commitment to lend.
The investors who clear this test comfortably are the ones who count their financed properties and their post-reset payment before they pick a loan size.
