The Quick Read: Usually six months of the subject property’s monthly payment, held in liquid funds after closing, with twelve months for first-time investors, on most programs in Lendmire’s wholesale network and subject to underwriting, and the 40-year term does not change the count by itself. On an interest-only structure, that payment is interest, taxes, insurance and dues, with no principal in it. The rest of this piece shows how the count is built and what it means in cash.
- Base count: six months on the subject property, subject to underwriting.
- First-time investors: twelve months.
- Payment basis: the interest-only payment on an interest-only loan, and the full payment on a fully amortizing one.
- Loan size: on these programs the months stay flat as the balance climbs. Credit, appraisals and leverage tighten instead.
- Cash-out: loan proceeds do not count toward reserves on this ladder.
Key Terms Defined
Reserves are liquid funds you still own after the down payment and closing costs are paid. The lender wants proof you can carry the property through a slow stretch.
PITIA is principal, interest, taxes, insurance and association dues, added up for one month.
ITIA is the same list without principal. On an interest-only loan, the reserve count and the coverage test use this figure.
Interest-only period is the stretch of the loan when you pay interest but no principal. On these programs it runs 120 months on 30- and 40-year terms.
Super jumbo is a lender label for very large balances. No official definition exists, so each program draws its own line.
Seasoning is how long money has sat in your account. A lender wants to see where large deposits came from.

What Does “40-Year Super Jumbo” Actually Mean?
It means three separate choices stacked together: a big balance, a 40-year term, and usually a 10-year interest-only window. Each one can be changed without touching the others.
Many buyers hear “40-year” and picture 40 years of paying principal. That is not how most of these loans work. A common structure pays interest only for the first 10 years, then amortizes the balance over the remaining 30. Scotsman Guide describes this exact shape, interest-only for the first 10 years and then a 30-year fixed-rate period, and places DSCR loans under the non-QM umbrella. Non-QM simply means a loan that falls outside the standard mortgage box.
| Structure | Early payment | Reserve basis |
|---|---|---|
| 40-year, 120-month IO | Interest, taxes, insurance, dues | ITIA |
| 40-year, fully amortizing | Principal plus the rest | PITIA |
| 30-year, 120-month IO | Interest, taxes, insurance, dues | ITIA |
The 40-year term mostly changes how gentle the step-up is later. Lendmire’s piece How to Use 40-Year Amortization on a Super Jumbo Bank Statement Loan covers the term on its own.
The Reserve Requirement: Months, Payment Basis, Property
Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Across the select wholesale programs that handle large balances, the standard ask is six months of payment on the subject property. If the loan is interest-only, the payment is ITIA. If it amortizes from day one, the payment is PITIA. These are typical program figures, and every file is underwritten individually.
The reserve count is a multiplication problem. Take the monthly figure for the property you are buying or refinancing. Multiply by six, or by twelve if you are a first-time investor. The result is the amount of verified liquid money you need left after closing.
Two details matter here.
First, the count applies to the subject property. On the network programs behind this ladder, other financed properties do not add reserves. A borrower can hold up to 20 financed properties on the program, and the subject-property count stays the same.
Second, the months are tied to the payment basis. Interest-only is reviewed on ITIA, so the same balance on an interest-only loan produces a smaller reserve target than on a fully amortizing one. That is a real benefit. It is also why the next section matters.
Does the Requirement Grow With Loan Size?
Not in months, on these programs. The count holds at six while the other conditions tighten as the balance rises. Some lenders do scale months upward with balance, so confirm the tested count on the term sheet before you assume either way.
Here is how the ladder moves. Every figure is a ceiling, reached only on files that meet the program, and all of it is subject to underwriting.
| Loan size | Max leverage, purchase | Credit | Cash-out |
|---|---|---|---|
| $150K to $1M | 80% | 660+ | Available |
| $1M to $1.5M | 75% | 700+ | Available |
| $1.5M to $3M | 75% | 720+ | Available |
| $3M to $4M | 65% | 700+ | — |
| Above $4M | 60%, on review | 700+ | — |
Two more triggers sit on top of the table. Loans above $2,000,000 need two appraisals. Loans above $3,000,000 add stricter credit-history seasoning and limit the program to citizens and permanent residents. Above $4,000,000, every request is reviewed case by case before submission, purchase or rate-and-term only.
So what rises with size? Leverage falls, credit requirements climb, and the file gets more scrutiny. What does not change? The six-month count and the first-time-investor doubling. The 40-year term does not move any of these either. It only changes the payment inside the coverage ratio.
(That is also why super jumbo gets confusing. Two programs can both say “reserves” and mean different multiples. Always ask which payment, which months, and which property.)
First-Time Investor or Experienced?
A first-time investor typically carries twelve months of reserves instead of six. The lender has no ownership history to lean on, so it asks for a thicker cushion.
Picture a high-income buyer who has owned a primary home for years but never a rental. On paper that buyer looks strong. For this program, though, the file is a first-time investor file, and the reserve target doubles. That surprises people who assume wealth alone solves it.
Short-term rentals add another wrinkle. On these programs, short-term rental files are limited to experienced investors, defined as twelve months owning income property in the last thirty-six. They also require coverage of 1.00 or higher and stop at $2,000,000. The rules for operating a short-term rental are set locally and change, so municipal permission has to be documented for the specific property.
What Counts as Reserves, and What Does Not
Only money you still hold after closing counts. The down payment and closing costs come out first. What is left must be liquid and verifiable.
Lenders typically review bank and brokerage statements. Large or unusual deposits draw questions, because the lender wants to know the money is yours and has been yours for a while. Seasoning rules vary by program. Some programs also discount retirement and brokerage balances rather than counting them at face value. That varies, so ask early which assets a given program accepts and how it values them.
Cash-out proceeds are the trap. On this ladder, cash-out never satisfies reserves. A borrower refinancing a multi-million-dollar rental cannot pull equity out and then point to that same cash as the cushion. The reserves have to come from other liquid funds. Some lenders outside this network treat it differently, which is why the question is worth asking before you build a plan around it.
For context on loans that fall in the cash-out category, Lendmire’s article How Many Months of Reserves a Second Home Jumbo Cash-Out Needs walks through a related case.
Worked Example: A $2,500,000 Purchase
Run the numbers on a modeled deal. Assume a $2,500,000 rental purchase at 75% leverage on a purchase, with coverage at 1.00 or better, a 40-year term and a 120-month interest-only period. These inputs are modeled assumptions, not market data. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
That price sits in the $1.5M-to-$3M band, so the file needs two appraisals and a 720 credit score on this ladder. Leverage of 75% on a purchase is the ceiling for the band. The down payment is the remaining 25%. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Now the cash picture. The components are shown below as percentages and month counts rather than dollar figures, because the calculator converts percentages into dollar figures.
| Cash component | How it is sized | Counts as reserves? |
|---|---|---|
| Down payment | 25% of price | No |
| Closing costs | Per file | No |
| Reserves, experienced | 6 months of ITIA | Yes |
| Reserves, first-time | 12 months of ITIA | Yes |
The interest-only basis keeps the reserve target lower than it would be on a fully amortizing 40-year loan. Principal drops out of the monthly figure, so the multiplication starts from a smaller number. The tradeoff is that the payment will rise at the end of the interest-only window.
Here is the part buyers miss. The total cash need is the down payment plus closing costs plus reserves. On a balance this size, reserves are a second pool of cash that has to sit untouched. Plan for three buckets, not one.
What Happens at the Interest-Only Reset?
The payment steps up after 120 months, because principal joins the monthly figure. On a 40-year note, 30 years remain to repay it. A 30-year interest-only loan would leave only 20. The step on the 40-year loan is gentler.
The catch is that qualification and reserves use ITIA, not the future payment. Some non-QM lenders instead qualify interest-only loans on the higher post-interest-only payment, as Scotsman Guide notes. That is a program-by-program difference, so confirm which payment your file is tested on.
Test the reset yourself. Ask what the property’s rent would cover once principal is added. If coverage would fall below 1.00, decide now whether you plan to refinance, sell, or hold more cash. Programs below 1.00 coverage exist through select lenders in the network, but leverage and terms adjust, subject to underwriting.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Why No Government Number Exists
No regulator sets a reserve figure for a DSCR loan. Each program writes its own, which is why counts differ from lender to lender.
What the rules do is draw a boundary. The CFPB’s small entity compliance guide says a Qualified Mortgage cannot carry interest-only payments or a term over 30 years. A 40-year interest-only loan is therefore non-QM by definition. DSCR loans are designed for non-owner-occupied investment properties, and because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Scotsman Guide adds that 40-year loans can be hard to find and bring lower payments but more total interest and slower equity build. Both points are fair. The long term trades cheaper monthly carry for a larger lifetime interest bill.
Common Mistakes
Counting the down payment as reserves. It is spent at closing. Reserves are what is left.
Using cash-out as the cushion. On this ladder, it never counts.
Assuming the term changes the count. The 40-year term changes the payment inside the ratio. It does not change the reserve months.
Forgetting the first-time multiplier. Twelve months, not six.
Confusing reserves with your own cushion. Reserves are a lender condition. Your vacancy and capital-repair cushion are separate, and a smart investor holds both. Lenders may average income across a year, while your bank account feels every slow month.
Skipping the post-reset test. The reserve math runs on interest-only, but your wallet will pay the higher figure later.
A shortfall at size usually means one of a few outcomes: waiting until you have more liquid funds, restructuring with lower leverage so the payment and reserve target shrink, or looking at a different program. A lower balance can ease the target, though it raises your down payment. 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.
Are You Ready to Apply?
Run through this list before you request a quote:
1. Identify whether you are a first-time investor, because that sets six months or twelve.
2. Confirm whether the loan will be interest-only or fully amortizing.
3. Total your liquid funds after the down payment and closing costs.
4. Set aside the cash-out proceeds question, since those funds will not count.
5. Gather bank and brokerage statements, and be ready to explain large deposits.
6. Check your credit against the band your balance falls in.
7. Model coverage today and after the interest-only window ends.

Frequently Asked Questions
Do reserves rise on a 40-year loan compared with a 30-year loan?
No. The term changes the payment inside the coverage ratio, not the reserve months. On an interest-only loan, the monthly figure is ITIA either way, subject to underwriting.
Is the reserve count ever lower than six months?
It can be on some programs, for example on conservative rate-and-term refinances, but that is a program-specific exception rather than the base rule. On the network programs behind this ladder, plan for six months and confirm any exception on the term sheet.
Do I need extra reserves for my other rentals?
Not on this program. The count applies to the subject property, and the program allows up to 20 financed properties. Underwriting still reviews your overall liquidity.
Can cash-out proceeds satisfy the reserve requirement?
No, not on this ladder. You need other liquid funds after closing. Some lenders outside the network may treat proceeds differently, so confirm the rule before relying on it. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Does a short-term rental carry a different reserve count?
The base count stays the same on this ladder, but short-term rental files carry their own conditions. They need coverage of 1.00 or higher, experienced-investor status, and loan amounts to $2,000,000. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
