The Quick Read: Interest-only does not lower the down payment, because leverage caps set that number and the payment structure does not. On most purchase files across the wholesale network, plan on roughly 20% to 25% down, with some programs allowing less. Five-plus-unit buildings tend to sit at the conservative end of that range.
- The down payment is the price minus the loan. The maximum loan-to-value (LTV) sets the loan.
- Purchase leverage typically runs 75% to 80% LTV, subject to lender guidelines.
- Interest-only lowers the payment used in the coverage test. It does not lower the equity requirement.
- Cash cost includes closing costs and reserves, typically about 6 months of PITIA, with a step-up above $1,500,000.
- Coverage of 1.00 is where select programs start. Stronger ratios open better pricing and leverage.
Operators see the same mistake on 5+ unit files. An investor assumes interest-only means less cash at the table. It means a smaller monthly obligation. Those are two different tests, and a file has to clear both.

How Much Down Payment Is Typical on a 5+ Unit Interest-Only Loan?
Typical purchase leverage runs 75% to 80% LTV, which is 20% to 25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score, but those are the exception on a 5+ unit building. Whether a particular building lands at 75% or 80% depends on credit, coverage, and the property itself. All of it is subject to lender guidelines.
The down payment is just arithmetic. Take the price, subtract the loan, and what remains is your equity. A 75% LTV purchase means 25% down. An 80% LTV purchase means 20% down. The calculator on the site converts those percentages to dollars for an illustrative estimate. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Across the wholesale network, 5+ unit buildings are underwritten more conservatively than 1–4 unit rentals. Most lenders treat a building of five or more units as commercial multifamily for underwriting purposes, and an investor on the fence between a fourplex and a six-unit should expect the larger building to ask for equity at the higher end of the range. A weaker coverage ratio shrinks the loan and raises the cash needed.
| Transaction | Typical LTV | Typical down |
|---|---|---|
| Purchase | 75%–80% | 20%–25% |
| Select high-leverage purchase | up to 85% | about 15% |
| Cash-out refinance | up to 75% | n/a |
The 85% tier needs roughly a 700+ score and generally is not where a 5+ unit file ends up. Treat it as a ceiling, not a plan.
Does Interest-Only Change the Down Payment?
No. Interest-only changes the payment, and the LTV cap sets the equity. The structure matters for coverage, and coverage matters for loan size, but the cap is a separate constraint.
Here is the mechanical chain. A lender applies a maximum LTV to the purchase price or value. That gives a maximum loan. Then the lender tests whether the rent covers the payment on that loan. Interest-only lowers the payment in that second test, so a building that falls short on an amortizing payment may clear it on an interest-only one. But the first test still caps the loan. An interest-only structure can never pull the loan above the leverage ceiling.
So the structure helps in one direction. It can keep the loan from being cut back because of weak coverage. It cannot push the loan past the cap.
Interest-only periods and longer terms are available through select lenders in the network. The spine of the product is the 30-year fixed. Extended terms, such as a 40-year structure, and interest-only periods are options within certain programs, and ARM structures exist for investors who want them. Whether a given lender qualifies the file on the interest-only payment or on a fully amortizing payment is a program rule. Confirm it before you build a deal around it, because that single choice changes how much coverage the file shows.
How Does the Coverage Test Work on 5+ Units?
Five-plus-unit buildings are typically underwritten on net operating income (NOI) rather than gross rent. The commercial formula is NOI divided by annual debt service.
Residential-style DSCR on 1–4 units compares rent to PITIA, which is principal, interest, taxes, insurance, and any HOA dues. On a larger building, expect the lender to look at the rent roll, the leases, and operating history, then build NOI after expenses and vacancy. Broker pro formas do not carry weight here. Appraisers use an income approach rather than relying only on sales comps. For contrast, 2–4 unit rentals use the operating income form, Fannie Mae Form 1025, which does not govern DSCR files but shows where the small-building process ends.
Clearing the ratio is not the same as positive cash flow. DSCR compares income to the debt payment and nothing else. Repairs, vacancy, management, utilities, and capital expenses sit outside it. A building can clear 1.00 and still lose money after a roof claim.
Where does 1.00 fit? Many select programs start there. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage, which is the real reason investors chase it.
A Worked Example: Same Building, Two Structures
Consider a hypothetical 8-unit building priced at $1,200,000. These inputs are modeled assumptions, not market data.
- Structure A: 75% LTV, fully amortizing 30-year fixed. Down payment is 25%. Coverage clears roughly 1.10x.
- Structure B: 75% LTV, interest-only period. Down payment is still 25%. Coverage clears roughly 1.35x on the lower payment. Every figure here varies by lender and program, and guidelines, property type, leverage, and credit profile all apply.
The down payment did not move. What moved was the margin. Structure B leaves room if the rent roll softens or the appraiser trims NOI. That cushion is the real value of interest-only on a tight building.
Now flip it. Say Structure A comes in at 0.95x on the amortizing payment. Two paths a lender might review: interest-only on the same loan, which lifts the ratio, or a sub-1.00 path through select lenders, with leverage and terms adjusted. Neither is guaranteed. Both are reviewed against credit, reserves, and the property.
The tradeoff is real. Interest-only builds no equity through principal paydown, and the payment steps up when the interest-only period ends. An investor who plans to refinance or sell before that point has less exposure. One who plans to hold needs to underwrite the reset, not just the opening payment.
What Else Moves the Cash You Need at the Table?
The down payment is only the largest line. Total cash to close is the down payment, closing costs, escrows, and reserves.
Reserves vary by lender, leverage, loan size, and transaction type. They commonly run about 6 months of PITIA. 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. Do not plan around one number. Ask which tier the file lands in.
Sourcing and seasoning of funds is the quiet friction point. Lenders want to see where the down payment came from. Large recent deposits with no paper trail stall files. A document trail built before you go under contract keeps this from becoming a late-stage surprise. Whether a program allows borrowed down-payment funds is a program rule. Ask before you count on it.
The factors that push the required equity up or down:
- Credit. A 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers.
- Coverage strength. A thin ratio shrinks the loan and raises cash needed.
- Unit count and condition. Larger buildings and buildings with heavy vacancy or deferred maintenance draw more conservative sizing.
- Loan size. Standard programs run up to $3,000,000. Smaller balances route through select lenders. Above $2,500,000 the network generally holds to 30-year fixed structures, which matters if you were counting on an interest-only period on a large loan.
- Transaction type. Cash-out refinances top out around 75% LTV, with about 6 months of seasoning as the common expectation.
Lendmire’s complete DSCR loans guide lays out the full parameter set.
Can You Put Less Down on a 5+ Unit Building?
Rarely, and not through the standard path. Claims of 10% down on a 5+ unit building usually involve seller financing, a second lien, layered capital, or an owner-occupied program. Each carries a cost, and each is a different structure from a DSCR purchase.
Across the network, the realistic range for a 5+ unit purchase is the 75% to 80% LTV band. The 85% tier exists, but it is narrow and credit-dependent. An investor who needs to stretch below that is usually solving a cash problem, not a financing problem. Better options are a lower price, a smaller building, or recycling equity from another property through a cash-out refinance.
That last point is the real scaling constraint. Putting 20% to 25% down on every deal runs into a capital wall. Investors who scale tend to pull equity from seasoned holdings, then redeploy it. A cash-out on a standard rental tops out around 75% LTV in most of the network. Short-term-rental collateral sits lower, with cash-out at 70%.
The Business-Purpose Frame, Briefly
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. Federal rules treat credit extended primarily for a business purpose as exempt from consumer-credit requirements, and a creditor decides in each case whether the purpose qualifies, per CFPB Regulation Z § 1026.3. The official Reg Z commentary treats credit for non-owner-occupied rental property as business purpose.
Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. It is not a no-paperwork product. On a 5+ unit file, expect rent rolls, leases, and operating history.
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.
Key Terms Defined
LTV (loan-to-value): The loan amount divided by the purchase price or appraised value. The down payment is the remainder.
DSCR: Debt service coverage ratio. Income divided by the debt payment, used to test whether the property supports the loan.
PITIA: Principal, interest, taxes, insurance, and any association dues. The full monthly obligation on the property.
NOI: Net operating income. Rental income less operating expenses and vacancy, before debt service.
Interest-only period: A stretch at the start of the loan where the payment covers interest alone. Principal payments begin when it ends.
Seasoning: The minimum time you must own a property before a cash-out refinance is available.
Before You Make an Offer
1. Confirm the unit count and that the property type is eligible. Manufactured homes, log homes, and barndominiums are not offered in these programs.
2. Get the rent roll and leases in hand. Build NOI on actual numbers.
3. Ask whether coverage is tested on the interest-only payment or a fully amortizing one.
4. Set aside the down payment, closing costs, and reserves, and document where each came from.
5. Underwrite the payment reset if you plan to hold past the interest-only period.
6. Run the file through the calculator for an illustrative estimate, then confirm with a broker.
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
Is a down payment required on an interest-only DSCR loan?
Yes. Leverage caps apply regardless of payment structure. On most purchase files the network sits at 75% to 80% LTV, so 20% to 25% down is typical, subject to lender guidelines. Select high-leverage programs reach 85% LTV with roughly a 700+ score.
Does interest-only lower my down payment?
No. It lowers the payment used in the coverage test, which can keep the loan from being cut back for weak coverage. It does not raise the LTV cap or reduce the equity the cap requires.
How much cash do I need beyond the down payment?
Plan for closing costs and reserves. Reserves commonly run about 6 months of PITIA, can be waived on conservative rate-term files at modest leverage under $1,500,000, and typically step up to about 9 months above that size. They vary by lender, leverage, and transaction type.
Does a bigger down payment help me qualify?
Yes, it can. Lower leverage means a smaller loan and a smaller payment, which lifts the coverage ratio. It never erases credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
What happens when the interest-only period ends?
The payment resets to fully amortizing, so it rises. Investors who plan to hold should underwrite that reset up front. Those who expect to refinance or sell earlier carry less exposure to it.
