The Quick Read: The right setup is a standalone line of credit on a rental you already own, qualified on that rental’s income, drawn and documented before you apply for the purchase loan, with the purchase lender confirming in advance that it accepts borrowed funds as the down payment. Which wholesale program fits depends on your property, credit, and combined leverage. Every file is underwritten individually, subject to lender guidelines.
- A DSCR HELOC is a line of credit on a rental you keep. It is a second lien behind your first mortgage, or a first lien if the rental has no mortgage.
- The line is reviewed on the rental’s rent, not your personal income, with a minimum coverage of 1.10x on a stress payment, through select programs.
- Second-lien leverage tops out at 70% combined loan-to-value (CLTV). First-lien leverage reaches 75% loan-to-value (LTV) at the top credit tier.
- The line is never closed together with a purchase. The new property’s lender decides whether borrowed funds count toward your down payment.
- At least 80% of the line is drawn at closing, so size it to the need rather than to the maximum.
What Does “DSCR HELOC” Actually Mean?
A DSCR HELOC is one loan, and the down payment strategy around it involves two. The first loan is a line of credit secured by a rental you already own. The second is the DSCR purchase loan on the next property. Each one is judged on its own.
The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. That means no traditional personal-income documentation, W-2s, or personal income calculation. DSCR stands for debt service coverage ratio. It is monthly rent divided by the monthly payment the lender tests against.
The purchase loan is judged separately. The new property’s rent is measured against that property’s own housing payment. Your HELOC payment does not enter that ratio.
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 “best program” question is really two questions. Which line fits your rental and equity? And will the purchase program accept what you draw? Brokers answer the second question first, because a perfect line is useless if the purchase lender refuses the money.

How Does Underwriting Treat the Line, Step by Step?
Underwriting runs in a fixed order: pick the source rental, test its rent, check leverage and credit, order the valuation, then draw and document. Each step has its own pass-or-fail test. A file can clear coverage and still fail on seasoning or property type.
Step 1: Pick the source rental. The line sits on a rental you keep. It can be a standalone second lien behind your existing first mortgage. It can also be a standalone first lien on a rental with no mortgage. It is never a third lien. It is never placed on your own home or a second home.
The line is never closed together with a purchase. A second lien on the property you are buying is not part of this program. If your plan depends on borrowing against the new property at its own closing, this is the wrong tool.
Step 2: Test the rent. The minimum coverage is 1.10x. Gross monthly rent is divided by a qualifying payment. That payment is a stress payment, calculated as if the entire credit limit were borrowed and the rate were higher than the starting rate. It is tested on the whole line, not just the part you plan to draw.
Rent is the lesser of the appraiser’s market rent schedule (Form 1007) or your lease. A lease above market can count with three months of receipts. A lease in place is required. A two-to-four-unit property can have at most one vacant unit.
On a second lien, the lender’s own coverage calculation governs how the first mortgage payment enters the math. Any ratio you run yourself is illustrative.
Step 3: Check leverage and credit. The leverage tiers are in the next section. Credit minimums are 720 on a second lien and 700 on a first lien. The lender’s own credit report sets your tier. The program looks for no 30-day mortgage late in the last 12 months. It also looks for 48 months since any bankruptcy, foreclosure, short sale, or deed-in-lieu.
No reserves and no cash to close are required on the line itself. The purchase loan has its own reserve test, which we cover below.
Step 4: Order the valuation. Lines up to $400,000 use an automated valuation (confidence score of 85 or better) with a property inspection report, or a full interior appraisal. Lines above $400,000 require a full interior appraisal. Appraisal waivers are not accepted.
Step 5: Clear seasoning. A rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
This matters if you recently did a cash-out refinance on the rental. The refinance restarts the first clock, and the rental cannot carry the line until it runs out.
Step 6: Draw and document. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. Keep the draw in a bank account in your name, and move it to the purchase from there. The paper trail from the draw to the closing table is what the next lender will ask to see.
Second Lien or First Lien? The Structures Compared
The structure depends on whether the rental carries a mortgage. A rental with a mortgage you want to keep takes a second lien. A rental with no mortgage takes a first lien, which allows higher leverage at the top credit tier. Below are the ceilings, subject to underwriting.
| Factor | Second lien | First lien |
|---|---|---|
| Rental has | A mortgage you keep | No mortgage |
| Leverage measure | CLTV (combined) | LTV |
| Top leverage | 70% CLTV at 720+ | 75% LTV at 740+ |
| Lower tiers | None below 720 | 70% LTV at 700 to 739 |
| Line size | $50,000 to $500,000 | To $500,000, then to $1,000,000 |
| Credit floor | 720 | 700 |
First-lien lines above $500,000 carry a 65% LTV ceiling at 720 or better. Lines run to $1,000,000. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
CLTV counts your first mortgage balance plus the new line, divided by value. Here is a percentage-only illustration. Say your first mortgage already uses 50% of the rental’s value. A second lien at a 70% CLTV ceiling leaves room for about 20 points of value. Whether that covers a down payment depends on what the next purchase needs, which varies by purchase program.
A few other limits apply to both structures:
- The rate is variable.
- The draw period is five years interest-only on the drawn balance. The repayment period is 25 years fully amortizing, with a 30-year maturity.
- You can hold the rental in an LLC. The members sign as guarantors, subject to program terms.
- The borrowers on the line do not have to match the borrowers on the first mortgage.
- Eligible borrowers are U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- A single borrower can have at most 5 loans or $2,500,000 with the program.
Eligible property includes single-family homes, PUDs, townhomes, two-to-four-unit properties, and warrantable and non-warrantable condominiums, plus lots up to 10 acres. Rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, and age-restricted communities are outside this lane. So are hobby farms, modular and log homes, land contracts, and mixed-use. A property listed for sale in the prior two months or carrying a solar lien is also out. A declining-market flag can lower the ceiling by 5 points.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. Those states are Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia, and Washington.
Where Does the General Rule Break?
The general rule is that rent qualifies the line, and the cash then becomes your down payment. It breaks in six places: the purchase lender’s borrowed-funds rule, reserves, your own cash flow, the cash-out alternative, delayed financing, and the cost of investment-property equity. Know these before you open anything.
The purchase lender refuses or caps borrowed funds. Across the programs we see in our wholesale network, treatment of borrowed funds differs. Some accept a documented HELOC draw for the down payment and closing costs. Others cap the borrowed share. A few want your down payment from unborrowed funds. If your plan is a 100% borrowed down payment, confirm the purchase program allows it before you open the line.
Mainstream consumer coverage agrees that a HELOC can fund a down payment and closing costs up to the approved limit. Yahoo Finance also cautions that the approach strains buyers who are already stretched on debt.
Reserves come from somewhere else. Reserves are the cash a lender wants left in your accounts after closing. Many purchase programs accept documented borrowed funds for the down payment but exclude them from reserves. Funds for reserves usually need to be your own seasoned assets. The down payment, the closing costs, and the reserves are three separate tests, and each can fail on its own.
The ratio ignores your line payment, but your bank account does not. The coverage ratio on the new purchase tests that property’s rent against that property’s payment. Your HELOC payment is not in it. That does not make the HELOC payment disappear. You owe it every month, including any month the new rental sits empty.
With a drawn balance, the first five years are interest-only on what you borrowed. Clearing the coverage test does not prove the deal cash flows after both payments. Weigh both loans together.
A cash-out refinance is the alternative, not the same thing. A cash-out refinance replaces your first mortgage with one larger loan. A HELOC keeps the first mortgage in place and adds a line behind it. If your current first mortgage has terms you want to keep, the line protects them. If it does not, a refinance may fit better, but it restarts the seasoning clock. Lendmire’s DSCR cash-out refinance page covers that route.
Delayed financing has its own rules. Delayed financing means buying a property with cash and then taking cash back out. If purchase money came from a HELOC on another property, the refinance proceeds generally must repay it. A loan recorded at purchase also fails the all-cash condition. Waiving seasoning does not waive coverage, reserves, valuation, or leverage.
Investment-property equity costs more and carries more risk. Benzinga notes that a HELOC on an investment property uses that property as collateral and may cost more than one on a primary home. The White Coat Investor adds that these lines are harder to get than primary-residence ones. It also points out the lien creates foreclosure risk on the rental. Those are the realities of borrowing against a rental, and a program built for it prices that in. The rate and pricing terms come with the lender’s disclosures.
What Does the Decision Look Like in Practice?
In practice, the decision starts with the purchase lender, not the line. A borrower who opens the line first can end up with cash the purchase program will not count. Ask the purchase program its borrowed-funds rule, then size the line, then draw.
Consider a scenario. An investor owns a seasoned rental with a first mortgage and a lease in place. The rent covers the stress test with room to spare. The credit score sits above 720. The investor wants to buy a second rental through a DSCR purchase loan. The plan has a series of moves, listed below:
1. Ask the purchase program whether a documented HELOC draw can fund the down payment and closing costs, and whether any share must be unborrowed.
2. Confirm the source rental clears seasoning and the coverage test.
3. Size the line to the down payment and closing costs, not the maximum. Because at least 80% is drawn at closing, a bigger line means paying interest on money you do not need.
4. Draw into your own account and keep the statements.
5. Apply for the purchase loan with the draw records and loan terms in the file.
Coverage and leverage must both pass. A rental with strong rent but a high first mortgage balance can fail on CLTV. A rental with modest equity but a clean first-lien position can pass.
The right tool depends on what you hold and what you need:
- Many rentals and thin equity in each: a first-lien line on an unmortgaged rental often gives the most room.
- One mortgaged rental with equity: a second lien keeps the first mortgage in place.
- Equity only in your own home: this program does not apply. A primary-residence HELOC is a different, owner-occupied product, and this line is never offered on an owner-occupied home. Lendmire’s piece Best Investment Property HELOC Program to Cover a Down Payment on Another Home explains the difference.
Questions to ask any program before you apply:
- Does the purchase program accept borrowed funds for the down payment and closing costs?
- Is there a cap on the borrowed share?
- Are borrowed funds excluded from reserves?
- What valuation path applies to my line size?
- Does my rental’s property type fall inside the eligible list?
Rent that comfortably clears the stress test, a seasoned rental, and a purchase program that accepts documented borrowed funds are the three things that make this work. A stretched budget makes it a poor fit. A line you cannot carry through a soft rental month is not worth opening.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the monthly payment the lender tests; 1.10x means rent is 10% above that payment.
CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
Second lien: a loan that sits behind your first mortgage and is paid second if the property is sold or foreclosed.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Seasoning: the waiting period a lender wants after you buy or refinance a property before it will lend against it again.
Borrowed funds: money that came from a loan rather than your own savings, which some programs limit or exclude for reserves.
Stress payment: a higher test payment, calculated as if the whole limit were borrowed, used to check coverage.
Frequently Asked Questions
Can HELOC money be used as the down payment on a DSCR purchase loan?
Sometimes. Once drawn, the money is usable, but the purchase lender sets the rule on borrowed funds. Some programs accept it with documentation, some cap the share, and some require unborrowed funds. Ask before you open the line.
Does the HELOC payment count in the DSCR on the new rental?
No, the new loan’s ratio compares the new property’s rent to its own payment. The line’s payment is still your obligation, though, and you pay it from your own resources if the rent falls short. Treat the two payments as one cash-flow picture.
Can I close the line and the purchase at the same time?
No. The line is never closed together with a purchase, and it is not offered as a lien on the property being bought. The source rental must already be owned and seasoned.
What credit score and leverage does the program look for?
Typically 720 on a second lien, up to 70% CLTV on lines to $500,000. On a first lien, the floor is 700, with up to 75% LTV at 740 or better on lines to $500,000, subject to underwriting. Lines above $500,000 carry a 65% LTV ceiling.
