The Quick Read: A 40-year term does not change the down payment on a duplex, triplex or fourplex. Leverage caps, credit tier and loan size set the cash you bring, and the longer structure mainly changes how the rent-to-payment test is run. Most purchase files land at 20%-25% down, subject to lender guidelines.
- Most purchases run 75%-80% LTV, which means 20%-25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score.
- No DSCR program is zero-down. The cash must be the borrower’s own, not borrowed against a second lien.
- Coverage of 1.00 is where select programs start. A separate select-lender path goes below 1.00 with leverage and terms adjusted.
- Reserves commonly run about 6 months of PITIA, and about 9 months above $1,500,000.
- Extended terms and interest-only periods come through select lenders in the network. They are not universal.
Across the wholesale network Lendmire works with, the pattern is consistent. The down payment is a leverage question first. The term structure is a qualification question second. Mixing the two up is how investors end up short on cash at the closing table.

How Does the Down Payment Work on a 2-4 Unit Purchase?
The down payment is the purchase price minus the loan, and the loan is capped by a maximum LTV. At 75% LTV you put down 25%. At 80% LTV you put down 20%. Duplexes, triplexes and fourplexes generally follow the same leverage tiers as single-family homes in the programs Lendmire places files with.
Why is there no zero-down option? Lenders want the borrower to have real equity in the deal. DSCR loans are non-QM investor products. They are full recourse in most cases and qualify primarily on property-level rental income covering the payment, subject to lender guidelines. Skin in the game protects the lender when the borrower’s personal income is not the underwriting basis.
The cash also has to be clean. A second-lien loan taken out at closing to fund the down payment is something most programs will not accept, because the primary lender wants first position and wants the borrower’s own money in the property. Plan the down payment, reserves and closing costs as three separate buckets of liquid cash.
Key Terms Defined
DSCR: The debt service coverage ratio, which compares the property’s monthly rent to its monthly housing obligation.
PITIA: Principal, interest, taxes, insurance and any HOA dues, which together make the monthly obligation used in the ratio.
LTV: Loan-to-value, the loan amount as a percentage of the purchase price or appraised value.
Note term: The total length of the loan, such as 30 or 40 years.
Amortization: The schedule over which principal is paid down.
Interest-only (IO) period: A stretch at the start of the loan when the payment covers interest only and principal does not fall.
Reset: The point where the IO period ends and the payment steps up to include principal.
What Does “40-Year” Actually Mean?
A 40-year DSCR loan usually means a 40-year note with an interest-only period up front, commonly ten years, followed by amortization over the remaining years. It is not forty years of principal paydown from day one. That is the biggest misunderstanding in this product.
There are two common shapes. They behave differently.
| Feature | 40-Year Fully Amortizing | 40-Year With IO Period |
|---|---|---|
| Principal paydown | Starts immediately | Starts after the IO period |
| Early payment | Lower than a 30-year | Lowest of the options |
| Later payment | Stays level | Steps up at reset |
| Coverage effect | Lifts DSCR modestly | Lifts DSCR the most |
| What to confirm | Availability by lender | Which payment is tested |
The spine of the network is the 30-year fixed. Extended terms and interest-only periods are available through select lenders, and ARM structures exist for investors who prefer them. Above roughly $2,500,000 in loan size, the network generally holds to 30-year fixed structures. Loan sizes run up to $3,000,000 on standard programs.
Does a 40-Year Term Change the Down Payment?
Not directly. The LTV cap for your credit tier, loan size and property type sets the minimum cash in. A longer term lowers the payment, and that can help the coverage number, but it does not raise the leverage ceiling.
Here is the indirect effect. Say a fourplex sits just under the coverage threshold on a 30-year structure. A 40-year or IO structure lowers the payment in the ratio and may pull the file over. That can keep the investor in the 75%-80% LTV tier instead of being pushed to lower leverage. In that sense, the structure can protect your down payment, but it never shrinks it below the cap. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Be careful on one point. Some lenders size coverage to the post-IO payment rather than the IO payment. Ask which payment is tested before you count on the benefit.
Duplex, Triplex and Fourplex: What Changes?
Within the 2-4 unit range, the network’s leverage tiers are the same as for a single-family purchase. What changes is the rent math and, often, how much cushion the lender wants to see.
Rent is added across all units. Occupied units are counted at the actual lease. Vacant units are counted at market rent from the appraisal. The appraiser reports each unit’s rent on the small residential income property form, known as Fannie Mae Form 1025 and Freddie Mac Form 72. That form is often paired with the 1007 rent schedule and the 216 operating income statement, as Realvals describes. HUD references the same form pair for documenting market rent on 2-4 units in its own program. The forms matter here only as the place where unit-level rent gets documented.
| Item | Duplex | Triplex | Fourplex |
|---|---|---|---|
| Typical purchase LTV | 75%-80% | 75%-80% | 75%-80% |
| Typical down payment | 20%-25% | 20%-25% | 20%-25% |
| Reserves | About 6 months PITIA | About 6 months PITIA | About 6 months PITIA |
| Income basis | Rent from 2 units | Rent from 3 units | Rent from 4 units |
| Main sensitivity | One vacancy is large | Mid-sized swing | Diversified, but price-heavy |
A duplex with one empty unit can lose half its counted rent in one stroke. A fourplex with one empty unit loses a quarter. More units can smooth the coverage number, though larger purchase prices can pull the loan toward the higher reserve tier above $1,500,000.
Five or more units are a different category. Those loans are typically underwritten as commercial or small-balance multifamily, with different rules. This article covers only 2-4 units. Properties like manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs.
Run the Numbers: A Duplex and a Fourplex
Consider a duplex priced at $400,000, purchased at 75% LTV. The investor puts down 25%. On a 30-year fixed structure, suppose rent covers PITIA at roughly 1.05x. That clears the floor of select programs, but with little margin. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Now run the same duplex on a 40-year IO structure through a select lender. The lower early payment might lift coverage toward 1.2x. The down payment stays at 25%. Only the coverage improves. These are modeled assumptions, not market data.
Picture a fourplex at $700,000 and 80% LTV, which means 20% down. Credit and coverage need to be stronger to reach that tier. If the coverage lands near 1.0x, a lender may offer 75% LTV instead, moving the down payment to 25%. Same building. Different cash required. The investor with a 700+ score and solid coverage can sometimes reach the 85% LTV tier through select programs, which would mean 15% down. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Here is the catch. A rent that is too low for the price pulls leverage down. The advertised minimum down payment is often not the actual down payment. Investors who shop high-leverage tiers on properties with thin rent frequently find that the real number is the 25% tier.
What Moves Your Tier?
Five variables decide where a file lands:
1. Credit score. A 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers.
2. Coverage ratio. Stronger coverage opens better pricing and leverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted.
3. Loan size. Reserve requirements step up above $1,500,000, and structure options narrow above $2,500,000.
4. Property type. The property must be an eligible type, and 2-4 unit residential is.
5. Transaction type. Purchase, rate-and-term and cash-out each carry different ceilings.
A bigger down payment lowers the loan, lowers the payment and can lift the coverage number. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. No-ratio structures exist only through select lenders, generally for borrowers who already own a primary residence.
One more point on what the ratio means. DSCR compares rent to PITIA and nothing else. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. Don’t treat the ratio as a profit forecast.
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.
Reserves, Closing Costs and Total Cash to Close
Reserves are measured in months of PITIA and vary by lender, leverage, loan size and transaction type. About 6 months is common. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months. Reserves are verified cash that stays in your accounts. They are separate from the down payment.
Closing costs come on top of both. So total liquidity needed is down payment plus closing costs plus reserves. An investor who budgets only for the down payment will be short.
On an interest-only structure, ask how reserves are counted. The IO payment is lower, but some files size reserves on a fully amortized payment. The answer varies by lender.
Purchase vs. Refinance Equity
On a purchase, you bring cash. On a refinance, your existing equity does the same job. Rate-and-term refinance ceilings run higher in the program parameters, up to 85% LTV, while cash-out tops out around 75% LTV across most of the network, with about 6 months of seasoning commonly expected.
Many investors use cash-out equity from one rental as the down payment on the next. That works when the proceeds are seasoned, documented and sitting in the borrower’s own account. See Lendmire’s piece How to Qualify for a 40-Year DSCR Loan on a 2-4 Unit Property for the qualification side. For a deeper walk-through of program mechanics, the complete DSCR loans guide covers the full picture.
What Happens When the Interest-Only Period Ends?
The payment steps up. After the IO window, the loan amortizes over the remaining years, and principal is now part of every payment. For a ten-year IO on a 40-year note, that means paying down principal over thirty years instead of forty. Rent must grow, or the investor must plan to refinance or sell before the reset.
This is the real tradeoff. A 40-year IO structure lifts coverage today at the cost of no principal paydown for a decade and a bigger payment later. For a buy-and-hold investor counting on rent growth, that can be reasonable. For an investor with a thin margin and no exit plan, the reset is a risk worth sizing before committing.
Conventional financing often offers better pricing on 1-4 unit purchases, but it requires full personal income documentation. DSCR trades some pricing for property-based qualification and flexibility. Which is better depends on your income picture and portfolio size.
Questions to Ask Before You Sign a Term Sheet
- Is the 40-year term fully amortizing, or interest-only first?
- Which payment is used to test coverage: the IO payment or the post-reset payment?
- What is the maximum LTV at my credit score, loan size and unit count?
- How many months of reserves apply, and how are they counted?
- Is a prepayment penalty attached?
- Are vacant units counted at appraisal market rent?
Frequently Asked Questions
Is there a zero-down DSCR loan on a duplex, triplex or fourplex?
No. Every DSCR program in the network requires borrower equity. Most purchases land at 20%-25% down, and select high-leverage programs reach 85% LTV, or 15% down, with roughly a 700+ score. The money must be the borrower’s own, not borrowed through a second lien. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Does a fourplex need more down payment than a duplex?
Not in the network’s standard tiers, which treat 2-4 units like single-family on leverage. The difference shows up in rent math, reserves and loan size. A higher price can push the loan into the larger-balance reserve tier, and thin rent can pull leverage down.
Does a 40-year term lower my down payment?
No. The term affects the payment, which affects coverage. A lower payment may help a marginal file stay in a higher-leverage tier, but the LTV cap itself does not change. Extended terms come through select lenders, so availability varies.
Can I use gift funds or borrowed money for the down payment?
Generally the cash must be the borrower’s own and properly sourced. Most programs do not accept a second-position loan at closing to fund it. Rules on gifts vary by lender, so confirm before relying on them.
Can I buy in an LLC?
Yes in many cases, subject to lender program eligibility. Entity vesting is common for investor purchases, though documentation requirements differ by program.
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. Reach the team at 828-256-2183 or request a quote. Tax treatment varies; consult a qualified professional.
Every unit’s lease or market rent feeds the coverage number, so a fully leased fourplex with documented rents often carries a stronger file than a half-empty duplex at a lower price.
