The Quick Read: A DSCR lender counts reserves as the documented liquid assets left after closing, measured in months of the full monthly obligation (principal, interest, taxes, insurance, and any association dues) on the subject property. A 40-year term has no reserve rule of its own. It changes which payment the months are multiplied against, and that choice is set by the program.
- Reserves are counted in months of PITIA, not as a flat dollar sum.
- Most programs in the wholesale network ask for about 6 months, with about 9 months above $1,500,000, subject to lender guidelines.
- Funds to close come out first. Only what remains after the down payment and closing costs counts.
- Retirement and brokerage balances are usually accepted at a discount, not at full value.
- Which payment is used in the multiplication on an interest-only 40-year file is a program rule. Confirm it before you plan your cash.
Investors tend to focus on the coverage ratio and the down payment. Reserves are the third cash bucket, and on a long-term structure they deserve more attention than they get. This piece walks through the count the way an underwriter does it. For the full picture of how these loans work, see the complete DSCR loans guide.

Key Terms Defined
- Reserves: Liquid assets you still hold after closing, separate from your down payment and closing costs.
- PITIA: The monthly total of principal, interest, taxes, insurance, and association dues on the property.
- Interest-only period: A stretch of the loan, often the first 10 years of a 40-year note, when the payment covers interest and no principal. The CFPB explains that the payment rises once that period ends.
- Funds to close: The cash needed at the table, meaning the down payment plus closing costs.
- Seasoning: How long funds have been sitting in an account before they count.
- Haircut: The percentage discount applied to assets that are not plain cash.
What Does “40-Year” Mean for the Payment Reserves Are Built On?
It means the payment can take one of three shapes, and the shape drives the dollar target. Reserves always equal months times a monthly payment. The term and structure decide what that payment is.
A 40-year DSCR loan is most often a 40-year note with a 10-year interest-only window followed by 30 years of amortization. Less often it is fully amortizing for all 40 years. Extended terms and interest-only periods are available through select lenders in the network, while the 30-year fixed remains the spine of the product.
| Structure | Payment during early years | Effect on the reserve target |
|---|---|---|
| 30-year fixed | Fully amortizing | Baseline |
| 40-year, fully amortizing | Lower than 30-year | Smaller target |
| 40-year, 10-year IO | Interest only | Smaller or baseline, by program |
Here is the catch. Some programs test the coverage ratio at the interest-only payment, which lifts the ratio. Others test at the fully amortizing payment. Reserves do not automatically follow the same choice as the ratio. One program may multiply months by the interest-only payment. Another may use a fully amortizing figure for the reserve base. Treat that as a program-level rule, not an industry rule, and get the answer in writing before you set your cash plan.
Leverage matters too. Choosing interest-only can cap leverage below the fully amortizing path on some programs. So the cash you need is more than the reserve line. A lower leverage cap raises your down payment, and reserves sit on top of it.
How Does the Underwriter Count Reserves, Step by Step?
The count runs in a fixed order. Underwriters start with documented balances and end with a number of months. The sequence below is how most programs in the network approach it.
1. Gather the statements. Programs generally ask for about two months of bank or brokerage statements.
2. Remove ineligible assets. Gift funds, borrowed funds, and unvested or illiquid holdings generally do not count.
3. Apply discounts. Retirement accounts and stock or bond portfolios are typically counted at a reduced value. The logic is simple: selling them can trigger taxes, penalties, or market swings, so the lender credits less than the face value.
4. Subtract funds to close. The down payment and closing costs come out of the eligible total. Fannie Mae’s selling guide uses this same post-closing logic for its own loans, with reserves expressed as months of PITIA. DSCR programs are separate and set their own terms, but the arithmetic habit is familiar.
5. Build the monthly payment. Add principal and interest (or interest only, where the program uses it), taxes, insurance, and any dues.
6. Divide and compare. Take what is left after step 4, divide by the monthly figure, and compare the resulting months to the program requirement.
That sixth step is where files fail quietly. A borrower may hold plenty in total assets and still fall short once funds to close are removed.
A Worked Example: Same Property, Three Structures
Take one hypothetical rental with a purchase price in the mid-six figures, bought at 75% LTV on a purchase of an investment property. The borrower’s eligible assets after closing are the same under each structure. Only the payment base changes. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
| Structure | Reserve base | Months of reserves shown | Direction of result |
|---|---|---|---|
| 30-year fixed | Amortizing payment | Baseline | Reference case |
| 40-year, fully amortizing | Amortizing payment | Slightly more | Easier to clear |
| 40-year, 10-year IO | Program-dependent | More if IO used, same if not | Check the program |
The point of the table is direction, not dollars. A lower payment base stretches the same cash across more months. A requirement of about 6 months is easier to meet when the monthly figure is smaller.
Now the failure case. Picture an investor with a large brokerage account and a retirement account. Total balances look comfortable. After the retirement account is discounted, and after the down payment and closing costs are taken out, the remaining total covers fewer months than the program needs. Nothing about the property changed. The borrower simply counted gross balances instead of eligible, discounted, post-closing balances.
What Counts and What Doesn’t?
Cash in checking and savings counts at full value. Almost everything else counts at a discount or not at all. The treatment below reflects how most programs approach each asset, and the exact haircut varies by lender.
| Asset | Typical treatment | Why |
|---|---|---|
| Checking and savings | Counts in full | Already liquid |
| Brokerage accounts | Counted with a discount | Market value moves |
| Retirement accounts | Counted with a discount | Taxes and penalties on withdrawal |
| Cash-out proceeds (refinance) | Often counts | Cash in hand at closing |
| Business accounts | Depends on control | Borrower must control the funds |
| Gift funds | Generally not counted | Not the borrower’s own assets |
| Borrowed funds | Not counted | Creates new debt |
Foreign-national borrowers often face lower maximum leverage and may need reserves held in a U.S.-based account. Crypto and receivables are treated inconsistently from one lender to the next, so ask before you count on them.
What Moves the Requirement Up or Down?
Loan size is the clearest driver. On most files in the network, the requirement sits at about 6 months of PITIA. Above $1,500,000 it typically steps up to about 9 months. Conservative rate-and-term files at modest leverage under that size can see reserves waived on some programs. Those are ranges, not promises, and every file is reviewed individually.
Other drivers:
- Leverage. Higher LTV tends to bring a larger ask.
- Credit. A 620 floor exists in parts of the network, most programs want about 660, and 700+ opens the strongest tiers.
- Coverage ratio. A stronger ratio can soften the ask. A thin one can raise it.
- Transaction type. Purchase, rate-and-term, and cash-out each carry different expectations.
- Short-term rentals. Expect a 640+ score and about 12 months of hosting history, with income based on an STR projection rather than a standard rent figure.
Here is a trap worth naming. A larger down payment lowers the monthly payment and can lift the coverage ratio. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
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.
What Happens When the Interest-Only Period Ends?
The payment steps up, and your reserves should be sized for the new figure, not just the starting one. On a 10-year interest-only window followed by 30 years of amortization, the monthly obligation rises at the reset because principal is added. The CFPB notes that payments on an interest-only loan go up once the interest-only period ends.
Lender-required reserves are a minimum, not a plan. Run your own stress test. Ask what the property’s rent covers at the higher payment, and whether your cushion survives a vacancy and a repair in the same year. Clearing 1.00 on coverage does not mean positive cash flow. DSCR compares rent to PITIA only, and repairs, vacancy, management, utilities, and capital expenses all sit outside it.
A 40-year structure is a defensible choice for an investor who wants a lower early payment and has a plan for the reset. It is the wrong tool for an investor counting on the initial payment to stay put forever.
What About Multiple Loans and Entity Ownership?
Each financed property tends to need its own cash. Investors scaling a portfolio often find that reserves, not the down payment, become the binding constraint. Fannie Mae’s guidance on multiple financed properties shows the same concept in the conventional world, where additional reserves apply as the number of financed properties grows. DSCR programs set their own terms, so ask whether a lender pools reserves across your loans or counts them separately, and whether funds are earmarked against loans you already hold.
On entity ownership, the control test matters. If reserves sit in an LLC account, the lender will want to see that you control the funds, subject to program guidelines. Reserves held personally may be treated differently from those held in the entity.
Portfolio or blanket loans can follow different reserve rules from single-property loans, so do not assume the single-property count carries over.
Documentation and Timing
Statements go stale. On a long closing, a statement that was current at application can age out, so plan for a refresh. A simple pre-application routine helps:
- Keep balances steady. Avoid large withdrawals.
- Explain any large deposit with paperwork before the underwriter asks.
- Do not move money between accounts without a paper trail.
- Hold funds in your own name, or in an entity you control, per program requirements.
The short version: stable accounts with clean statements make the count simple.
Questions to Ask Your Lender Before You Commit
- Is the reserve base the interest-only payment or the fully amortizing payment?
- At what loan size does the month count step up?
- What haircut applies to retirement and brokerage assets?
- Do cash-out proceeds count toward reserves on this program?
- Are reserves pooled across my other financed properties or counted separately?
- Does choosing interest-only change my maximum leverage?
Where a lender hesitates on any of these, get the answer in writing. A mortgage broker who sees many lenders’ guidelines can compare how different programs treat the same file. If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals.
Frequently Asked Questions
How many months of reserves does a 40-year DSCR loan need?
Most programs in the network ask for about 6 months of PITIA, rising to about 9 months above $1,500,000. Conservative rate-and-term files at modest leverage can see reserves waived. The 40-year term itself does not set the number. Loan size, leverage, credit, and transaction type do, subject to lender guidelines.
Do reserves use the interest-only payment or the full payment?
It depends on the program. Some multiply months by the interest-only payment, which gives a smaller dollar target. Others use a fully amortizing figure. Ask which applies before you plan your cash, and do not assume reserves follow the same choice as the coverage ratio.
Can retirement accounts count as reserves?
Usually yes, but at a discount rather than full value. Lenders discount them because withdrawal can trigger taxes, penalties, and market swings. The exact percentage varies by lender, so confirm it for your program.
Can cash-out proceeds count toward reserves?
On many refinance files, yes. Cash-out proceeds in hand at closing can count toward reserves, though cash-out leverage tops out around 75% LTV on standard rentals, and about 6 months of seasoning is the common expectation. Confirm the treatment with the specific program. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
What happens to my reserves when the interest-only period ends?
The lender’s requirement was set at closing, so it does not change. Your own risk does. The payment rises at the reset, so the same cushion covers fewer months. Stress-test your liquidity against the higher payment before you choose the structure.
