The Quick Read: Usually 20% to 25% down on a purchase, because most files in the network land at 75% to 80% LTV (loan-to-value, the loan as a share of the price). Interest-only changes the payment structure, not the basic down payment, though select lenders can trim leverage on interest-only loans, subject to lender guidelines.
- Typical purchase leverage: 75%–80% LTV on most files, so 20%–25% down.
- Higher leverage: select programs reach 85% LTV (15% down) with roughly a 700+ credit score.
- Zero down: not available on a DSCR purchase.
- Reserves: held on top of the down payment, commonly around 6 months of PITIA.
- Coverage: 1.00 is where many select programs start, and stronger ratios open better leverage.
Most investors assume interest-only is a discount on cash needed at closing. It is not. It is a discount on the monthly payment. Those are different things, and mixing them up is the most common planning error on these files.

What Does Interest-Only Change, and What Doesn’t It?
Interest-only lowers the payment the lender tests your rent against, which lifts your coverage ratio. It does not lower the equity the lender wants in the property. Leverage caps, credit floors, reserves, and property rules all stay in place.
A DSCR loan (debt service coverage ratio loan) qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The ratio is rent divided by PITIA, which is principal, interest, taxes, insurance, and association dues. The Agora explainer lays out the same basic formula. Interest-only means you pay only the interest for an initial period, then the loan begins paying down principal. Extended terms and interest-only periods are available through select lenders in the network, built on top of the 30-year fixed that anchors most programs.
| Factor | Interest-only effect |
|---|---|
| Monthly payment | Lower during the interest-only period |
| Coverage ratio | Higher on the same rent |
| Down payment | Same grid, sometimes trimmed leverage |
| Credit and reserves | Unchanged rules still apply |
| Principal paydown | None during the interest-only period |
Here’s the catch: because the ratio looks better, investors assume leverage will too. Some select lenders do cap interest-only leverage a notch below amortizing loans, often about 5 points of LTV. Ask which grid your file uses before you budget the cash. This varies by lender, so treat it as a question to ask, not a rule.
How Much Down Payment Is Typical on a Single-Family Purchase?
Across the wholesale network, most single-family purchase files sit at 75% to 80% LTV, which means 20% to 25% down. Select high-leverage programs reach 85% LTV, or 15% down, generally with a score around 700 or better. Eligibility depends on credit, coverage, and the property.
Market education sources describe a similar range. yieldstack.ai puts typical DSCR down payments at 20% to 30%, which is a wider band than the network’s usual tiers. Within the network, your tier depends mostly on three things:
- Credit score. A 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers.
- Coverage ratio. Stronger rent coverage supports more leverage. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted, which usually means more down.
- Loan size. Standard programs run up to $3,000,000. Above $2,500,000, the network generally holds to 30-year fixed structures, so an interest-only request on a very large loan may not be an option.
Cash-out refinances work differently. Leverage tops out around 75% LTV across most of the network, and about 6 months of seasoning is the common expectation. If you are refinancing a single-family rental you already own, the cash-out line is your ceiling, not the purchase tier. Every figure here varies by lender and program: guidelines, property type, leverage, and credit profile all apply.
Why Rent Coverage Often Sets the Real Number
Rent coverage frequently decides how much you put down, because the loan is sized to what the rent can carry. If the rent doesn’t clear the coverage floor at the maximum LTV, the loan shrinks and your down payment grows. The yieldstack.ai explainer makes the same point: coverage, not the leverage cap, is usually the binding constraint.
Consider a scenario with a single-family house priced at $350,000. At 80% LTV with rent that clears roughly 1.2x on an interest-only payment, the file looks clean. Now suppose the same house in a high-price, low-rent pocket tests closer to 0.9x at that leverage. The lender either routes the file to a select sub-1.00 path with adjusted leverage and terms, or the loan is cut back until coverage works. Either way, you bring more cash. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
This is where interest-only earns its keep. Removing principal from the tested payment can lift a thin ratio, and that can move you into a better tier. Some lenders qualify the borrower on the fully amortizing payment instead, so confirm which method applies before you count on the boost. For a deeper look at qualifying, Lendmire’s piece How to Qualify for an Interest-Only DSCR Loan on Single-Family Properties walks through it.
Pushing the other way works too. A larger down payment shrinks the loan, lowers the payment, and lifts the ratio. But more equity never erases credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
What Does the Full Cash Picture Look Like?
Your down payment is only one line of the cash you need at closing. Plan for the down payment, closing costs, prepaid items, an appraisal that includes a rent schedule, and reserves. Reserves sit beside the down payment, not inside it.
Reserves vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months. One number is never universal here.
Interest-only does not lighten that reserve requirement on its own. A common surprise is a file that works on down payment and coverage, then stalls because the reserve account is thin. Build the whole stack before you apply. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Source of funds matters too. Down payment money generally has to be seasoned and verified in your accounts. Lenders in the network want real capital in the deal, so a second loan taken at closing to cover the down payment is usually not allowed. Equity recycling is a legitimate path: proceeds from a cash-out refinance on another property can fund a down payment once they are in your account. Gift funds carry their own conditions, so confirm them early.
Is Zero Down or Low Down Possible?
No on zero down. A DSCR purchase always needs equity. The FHA 3.5% and VA 0% structures belong to owner-occupied financing, not investor loans. The lowest tier in the network is the select high-leverage program at 85% LTV, or 15% down, and it asks for a strong credit profile, roughly 700+. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Plan on 20% to 25% down and treat anything lower as a bonus that depends on your score, your coverage, and the property. First-time investors and lower-credit borrowers generally land at lower leverage, not higher.
When Does Interest-Only Fit a Single-Family Rental?
Interest-only fits when you want stronger early coverage and a smaller monthly payment, and you have a plan for the day principal payments start. It is a poor fit if you are counting on the structure to rescue a deal that doesn’t work otherwise.
Think of it as a tradeoff. You gain coverage and early cash flow. You give up principal paydown during the interest-only period, and the payment steps up when amortization begins. Build that step-up into your hold plan. Many investors plan a refinance or a sale before the reset, and a bigger down payment gives you more room for either.
One more caution. Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation. A house can clear coverage and still lose money month to month.
In files where an investor leans on interest-only to pass coverage, the weak spot is usually the reset, not the approval. The files that age well show enough rent cushion to survive the higher payment, not just the introductory one. Run both payments before you commit.
Property type matters as well. Single-family, condos, and 2-4 unit properties are all handled, but manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in these programs. Short-term rental collateral follows its own grid. Purchases go up to 75% LTV, refinances sit around 70%, and cash-out tops out at 70%, with about 12 months of hosting history expected. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
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.
Common Mistakes
- Assuming interest-only lowers the down payment. It lowers the payment. The leverage cap is the same or slightly lower.
- Budgeting only the down payment. Closing costs and reserves are separate.
- Counting on the max LTV. Thin rent coverage shrinks the loan below the cap.
- Planning a borrowed down payment. A second loan at closing is usually not allowed.
- Ignoring the reset. Test the post-interest-only payment, not just the first one.
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.
For the full framework behind these numbers, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
- LTV (loan-to-value): the loan amount divided by the purchase price or value. A 75% LTV means 25% down.
- PITIA: principal, interest, taxes, insurance, and association dues, the full monthly obligation rent is tested against.
- Interest-only period: a stretch at the start of the loan when you pay only interest, before principal payments begin.
- Reserves: liquid funds you hold after closing, counted in months of PITIA.
- Seasoning: the waiting period or time funds or a property must be held before a lender counts them. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Frequently Asked Questions
Does interest-only lower the down payment on a DSCR loan?
No, not on its own. Interest-only lowers the tested payment, which can lift your coverage ratio. The leverage cap stays on the lender’s grid, and some select lenders trim maximum LTV on interest-only loans. Ask which grid applies to your file.
Can I use gift funds for the down payment?
Sometimes. Gift funds carry conditions, and many programs want the borrower to contribute some of their own money. Funds generally need to be seasoned and verified. Confirm the rule early, because a second loan at closing to cover the down payment is usually not allowed.
Does my credit score change how much I put down?
Yes. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers, including select 85% LTV purchase programs. Lower scores generally mean lower leverage and more cash down.
How much do I need in reserves on top of the down payment?
Commonly about 6 months of PITIA, though it varies by lender, leverage, loan size, and transaction type. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months.
Is the down payment different on a cash-out refinance?
Yes, because there is no purchase down payment. Instead, leverage tops out around 75% LTV across most of the network on standard rentals, and about 6 months of seasoning is the common expectation. Short-term rental cash-out is lower, at 70%. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
