The Quick Read: Usually 20% to 25% down on an investment-property purchase, which means 75% to 80% LTV, and interest-only structure does not change that number, because it lowers the payment and can lift the coverage ratio but leaves the leverage cap, credit floor, and reserve rules exactly where the program set them. Being a business owner does not create a separate down-payment tier either. The loan looks at the rental property’s income rather than your personal income documentation, such as tax returns or pay stubs.
- Most purchase files across the network land at 75% to 80% LTV, which is 20% to 25% down, subject to lender guidelines.
- Select high-leverage programs reach 85% LTV on a purchase (15% down), typically for borrowers around a 700 score or better.
- Zero down is not a DSCR product.
- Interest-only helps the coverage ratio. It does not buy extra leverage.
- Reserves and closing costs are separate from the down payment, so plan for all three.
Does Interest-Only Change the Down Payment?
No. The down payment is the purchase price minus the loan, and the loan is capped by LTV. The payment structure sits on top of that cap. It does not move it.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
LTV stands for loan-to-value, the loan balance divided by the property’s value or purchase price. A cap of 80% on a purchase means the lender funds at most 80% and you cover the rest. Interest-only is a different dial. It controls what you pay each month during the interest-only period, not how much the lender will fund.
Where it helps is the second test. DSCR, the debt service coverage ratio, is the property’s monthly rent divided by its monthly obligation. That obligation is PITIA: principal, interest, taxes, insurance, and association dues. During an interest-only period the principal piece drops out, so the denominator shrinks and the ratio rises.
A higher ratio can help a deal clear a program’s coverage floor or reach a better pricing tier. It does not erase a leverage cap. A file at the 80% ceiling stays at 80% whether the payment is interest-only or fully amortizing.
What Down Payment Range Should You Plan For?
Plan on 20% to 25% down for most purchases, with 15% down possible only on select high-leverage programs. Across the wholesale network, most files land at 75% to 80% LTV on an investment-property purchase. Where you fall inside that band depends on credit, coverage, loan size, and property type.
Here is how the pieces usually stack up:
| Factor | What it typically does |
|---|---|
| Credit 700+ | Opens the strongest leverage tiers |
| Credit around 660 | Where most programs want you |
| Credit 620 | A floor in parts of the network, with tighter terms |
| Coverage at 1.00 or higher | Where many select programs start |
| Coverage below 1.00 | Select lenders, with leverage and terms adjusted |
Credit matters at every level. A 620 floor exists in parts of the network, but most programs want around 660, and 700 or higher unlocks the top leverage. Interest-only products through select lenders often set a higher credit floor than the baseline, commonly around 680.
Coverage works the same way. A rent-to-payment ratio of 1.00 is where many select programs start, so a ratio of 1.00 or higher gives you more options. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. In practice that usually means a larger down payment.
Loan size matters too. Standard programs run up to $3,000,000. Above $2,500,000 the network generally holds to 30-year fixed structures, so interest-only is typically off the table at that size. Below that, a 30-year fixed spine can be paired with an interest-only period through select lenders, along with extended 40-year terms.
For short-term rentals, the numbers shift. Purchase leverage tops out at 75%, and expect a 640 or higher score and about 12 months of hosting history. The coverage floor is 1.00 on purchases and refinances. Short-term rental rules vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Why Does the Lender Want Equity If the Rent Covers the Payment?
Because rent coverage and equity answer different questions. Coverage says the property can carry its payment. Equity says you have something to lose if it doesn’t.
Think about the lender’s position. If you stop paying, the remedy is foreclosure on the property. A larger down payment gives the lender cushion against a falling market or a messy sale. This is also why the lowest-leverage files tend to get the best terms, and why no one stacks a second loan on top to fund the down payment on a standard DSCR purchase.
The strongest files clear both tests. You have enough equity and enough rental coverage. A bigger down payment lowers the monthly payment and can lift the DSCR. It never overrides a leverage cap, credit floor, reserve rule, or property eligibility. One practical note: manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in these programs, so no down payment size fixes them.
A Worked Comparison: Interest-Only vs. Fully Amortizing
Run the numbers on a hypothetical rental purchased at 75% LTV with rent that covers the fully amortizing payment at roughly 1.00x. These are modeled assumptions, not market data. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Under a fully amortizing structure, that file sits right on the line. A lender with a 1.00 floor might accept it. A lender wanting stronger coverage for the best tier might not.
Switch to interest-only and the principal drops out of the payment. The same rent now covers the smaller obligation at a visibly higher ratio. That can move the file from borderline to comfortable.
What did not change? The down payment. It is still 25%, because 75% LTV is 75% LTV. The interest-only election improved coverage and nothing else. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Now flip it. Say the file is at 80% LTV and you want to drop your cash to 15% down. Interest-only will not do that. Only a program with a higher leverage tier, and a borrower profile to match, will. The two levers can also work together in the other direction. A larger down payment shrinks the loan, which also lifts coverage. If a file is tight on ratio, more equity is the dependable fix whichever payment structure you choose. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Keep one thing straight. Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
Who Counts as a Business Owner Here?
Business owner can mean three different things. Two fit this loan, and one does not.
Buying rentals through an entity. You own a business, or just an LLC, and you buy investment property in it. This is the core DSCR use case, subject to lender program eligibility on the entity.
Self-employed with heavy write-offs. Your traditional personal-income documentation shows low income on paper. You are still buying a rental, so a DSCR loan can fit. It is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so your return is not the test. Down-payment capital, not income, is often the binding constraint for you.
Financing a building for your own operations. A workshop or storefront your company will occupy is owner-occupied commercial financing. It is a different product, and DSCR does not fit it.
The same logic applies to a home you plan to live in. For a primary residence, a bank-statement or other documented-income loan is the usual route.
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. The Federal Register rulemaking treats investment-purpose loans as business-purpose, and a law-firm explainer on the business-purpose exemption describes a 14-day occupancy test that can tip a property into consumer treatment. Treat that as background, not a program rule.
Where Can the Down Payment Come From?
From your own verified funds, in accounts the lender can trace. Business accounts, personal savings, and proceeds from another property can all be sources, depending on the program.
What that looks like in practice:
- Bank statements that show the funds and where they came from.
- Documentation for large or recent deposits, such as a distribution from your business or proceeds from a cash-out on another property.
- Entity documents if you are vesting the property in an LLC, subject to program terms.
A cash-out refinance on a property you already own is a common way to free up capital for the next deal. On standard rentals, cash-out tops out around 75% LTV across most of the network, and about six months of seasoning is the common expectation. For short-term rental collateral, the cash-out ceiling is 70%, versus 75% on standard rentals. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Seller credits and borrowed second liens do not replace your equity on a standard DSCR purchase. The down payment is your money.
What Else Do You Need at Closing?
The down payment is one of three cash pots. Reserves and closing costs are separate from it.
Reserves are liquid funds the lender wants left over after closing, usually counted in months of PITIA. They vary by lender, leverage, loan size, and transaction type. Commonly it is around 6 months. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, while larger loans typically step up to about 9 months. Treat these as ranges, not promises.
Closing costs and prepaid items sit on top of both. Add the three pots together before you decide whether a deal fits your cash.
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. When the interest-only period ends, the loan begins to amortize, so principal enters the payment and the obligation rises. This is called a recast.
Two things follow. First, you built no equity through payments during the interest-only period. Your equity grew only if the property appreciated or you improved it. Second, a DSCR that works only on the interest-only payment will look weaker after the recast.
Some programs qualify the loan on the interest-only payment. Others qualify on the fully amortizing payment. Ask which applies, because a file qualified on the lower payment carries more risk later.
Have an exit plan before you elect interest-only: refinance, sell, or absorb the higher payment from the rents. If you are weighing a different structure, Lendmire’s piece How Much Down Payment Does a No-Ratio DSCR Loan for Business Owners Need? covers that path.
Brokers see the same pattern repeatedly. Investors treat interest-only as a leverage tool, then discover the leverage cap never moved. Ask about the cap first and the payment structure second.

Common Misconceptions
Interest-only means I can put less down. It does not. It helps the ratio, not the LTV ceiling.
A second loan can fund my down payment. On standard DSCR purchases, that is generally not allowed.
Skipping traditional personal-income documentation doesn’t mean skipping documentation. Credit, reserves, an appraisal with rent evidence, entity documents, and sourced funds are all still reviewed. The CFPB’s guide to Regulation Z also says the purpose of a business-purpose loan should be documented.
Interest-only lowers my coverage requirement. The test is the same. The payment is just smaller.
Low-down-payment programs for owner-occupants do not apply here. They are not available for investment-property DSCR loans.
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.
Key Terms Defined
DSCR: the property’s monthly rent divided by its monthly obligation, used to test whether rent covers the payment.
LTV: loan-to-value, the loan amount as a percentage of the property’s value or purchase price.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly obligation a lender counts.
Interest-only period: a stretch of the loan when you pay interest but no principal, so the payment is lower.
Reserves: liquid funds, counted in months of PITIA, that you hold after closing.
Recast: the point where the payment steps up as principal payments begin.
Frequently Asked Questions
Is zero down possible on an interest-only DSCR loan?
No. Standard DSCR purchases require your own equity, typically 20% to 25% down, with 15% down possible only on select high-leverage programs. Seller credits and borrowed second liens do not replace it. Reserves and closing costs are additional.
Is the down payment different for interest-only?
No. The interest-only election changes the payment used in the coverage calculation, not the LTV cap. A file at 75% to 80% LTV on a purchase stays there. Interest-only products at select lenders may carry a higher credit floor, so qualification can be tighter even though the down payment is the same.
Can I use business funds for the down payment?
Often yes, as long as the funds are documented and traceable, depending on program guidelines. Lenders typically want bank statements showing where the money came from. Recent large deposits, such as a distribution from your company, usually need an explanation.
Can I close in an LLC?
Many programs allow it, subject to lender program eligibility. Expect to provide entity documents. The down payment and leverage rules are the same whether you hold title personally or in an entity.
Can I live in the property?
No. DSCR loans are for non-owner-occupied investment properties. If you plan to occupy the property, a different loan, such as a documented-income mortgage, is the better fit.
