The Quick Read: The program that fits a landlord with a cheap first mortgage is a standalone second lien that sits behind the loan and leaves it untouched. The line is reviewed on the rental’s income, not the owner’s, and the first mortgage balance counts toward combined leverage. Which program is best depends on the property, the credit profile, and how much equity the owner needs.
- Through select programs, a second lien reaches up to 70% combined loan-to-value (CLTV) at a 720 credit score or better, on lines from $50,000 to $500,000, subject to underwriting.
- Rent has to cover a stress payment on the entire credit limit at least 1.10x, not just the drawn amount.
- The first mortgage stays in place, so a low balance leaves more room under the combined cap.
- The review uses no traditional personal-income documentation, W-2s or personal income calculation, subject to lender guidelines.
- It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Landlords with a good first mortgage hate the idea of replacing it. A cash-out refinance resets the whole balance, and the old terms are gone. A second-lien line lets the owner reach equity while the original loan keeps running. This article walks through how the structure works, how underwriting treats it, where it breaks, and how to decide.
What Is a DSCR HELOC on a Rental?
A DSCR HELOC is a revolving line of credit secured by a non-owner-occupied one-to-four-unit rental. It is reviewed on the property’s rent against a stress payment, so the owner’s personal income is never calculated. The CFPB’s HELOC explainer covers the basic mechanics: a draw period, then repayment, with the pledged property at risk.
Two lien positions exist on this program. With a mortgage still in place, the line is a standalone second lien behind it. With no mortgage, it is a standalone first lien. It never closes together with a purchase, it is never a third lien, and it is never a line on the owner’s own home. A primary-residence HELOC is a different, owner-occupied product.
“DSCR HELOC” is a market nickname, and sellers use it loosely. Some products labeled this way are closed-end second mortgages with a fixed amount and term. Others pay off the first mortgage and become a new first lien. The version described here is a revolving line, and the structure matters before the numbers do.
The line can be vested in the owner’s LLC, subject to lender program requirements. The members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.

How Does Underwriting Treat a Low First Mortgage?
Underwriting adds the first mortgage balance to the new line and divides by the property’s value. That is the combined loan-to-value, or CLTV. A small first balance leaves more room under the cap. A large one eats the room before the line starts.
Here is the step-by-step sequence across the programs Lendmire places files with.
1. Credit. A second lien needs a 720 score or better. Below 720 there is no second-lien option. The tier comes from the lender’s own credit report.
2. Combined leverage. Second liens reach up to 70% CLTV on lines up to $500,000, subject to underwriting. A declining-market flag can lower the ceiling by 5 points.
3. Coverage test. Gross monthly rent must cover the qualifying payment at 1.10x or better. That payment is fully amortizing, runs on the entire credit limit, and uses the start rate plus 2 percentage points. It is a stress payment, so it is higher than what the owner would pay on a partly drawn line.
4. Rent. The lender uses the lesser of the appraiser’s Form 1007 market rent or the 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.
5. Valuation. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal. Appraisal waivers are not accepted.
6. Title and insurance. Second liens above $400,000 get a full title policy. Smaller ones get an owner-and-encumbrance report. Hazard insurance covers both liens, with flood coverage where required.
One detail trips up many landlords. The test runs on the full limit, not the drawn amount. Sizing the line smaller than the maximum can therefore help the coverage number. Whether the first mortgage payment also joins the qualifying payment on a second lien is not published, so the lender’s own coverage calculation governs. Treat any online calculator that promises a precise second-lien ratio with caution.
What Does the Line Itself Look Like?
The line carries a 5-year interest-only draw period on the drawn balance, then a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each.
That draw rule changes how landlords should think about the product. It is not a standby line to open and leave idle. Most of the money comes out at closing, so the owner should size the line to a real use: a down payment on the next rental, a renovation, or paying down a higher-cost balance elsewhere.
The FTC’s home equity overview explains the revolving feature in plain terms: interest accrues on what is drawn, and the payment can change as the variable rate moves. Lenders can reduce credit limits under certain conditions. For a landlord, the practical risk is a payment that rises while rent stays flat. The rate and pricing terms come with the lender’s disclosures.
Second Lien or First Lien: Which Structure Applies?
The structure depends on whether the rental still has a mortgage. The two lien positions use different leverage tiers, and the first-lien figures are written as loan-to-value (LTV), not CLTV.
| Factor | Second lien (mortgage stays) | First lien (no mortgage) |
|---|---|---|
| Leverage measure | CLTV, first balance plus line | LTV, line only |
| Top leverage | Up to 70% CLTV at 720+ | Up to 75% LTV at 740+ |
| Mid tiers | 70% CLTV at 720 to 739 | 70% LTV at 700 to 739 |
| Minimum credit | 720 | 700 |
| Line range | $50,000 to $500,000 | Up to $1,000,000 |
| Lines above $500,000 | Not available | 65% LTV at 720+ |
All figures are ceilings through select programs, subject to underwriting. They are never offers. A first-lien line above $500,000 carries the lower 65% ceiling.
What “Best” Means for This Landlord
No single program wins for every owner. Lendmire is a mortgage broker that works with a network of wholesale DSCR HELOC lenders, so the useful question is which program fits the file. Several criteria decide it.
- First mortgage fate. The line must leave the first loan in place. Confirm the product is a true standalone second, not a refinance in disguise.
- Leverage headroom. Add the first balance to the planned line and divide by value. If the result lands above 70% on a second lien, the line must shrink or the structure changes.
- Coverage on the whole limit. Because the test runs on the full limit, a smaller line can clear when a larger one cannot.
- Title. LLC vesting is allowed on investment property, with members signing as guarantors.
- Property fit. Rural-designated property, row homes, condotels, leaseholds and age-restricted communities fall outside this lane.
- 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).
- Borrower status. US citizens, permanent residents and non-permanent residents with a Social Security number can use it. Foreign nationals and ITIN borrowers cannot.
A broker that shops several wholesale lenders can match these criteria to the scenario. A single lender’s page only tests its own product.
Where the Rule Breaks
The standalone second is not always the right move. These edge cases flip the answer.
The first mortgage forbids a junior lien. Most first mortgages permit one, but some do not. Check the note and the security instrument before spending money on a valuation. This is a dealbreaker that product pages tend to skip.
The first balance is already large. A low rate does not help if the balance leaves no CLTV room. Picture an owner whose first mortgage already sits near 60% of value. The line can only reach up to 10% of value more on a second lien. That may be too small to matter.
The cash need is big. Second liens stop at $500,000 and 70% CLTV. A landlord who needs more may find a cash-out refinance fits better, especially if the first mortgage rate is not actually attractive.
The rent does not cover the stress payment. Say a duplex rents for less than the 1.10x test requires on the full limit. Smaller line sizes may fix it. If they do not, the property may need a different structure, and that is a signal about the property, not the loan type.
The score is below 720. A second lien has no cell under 720. A first lien opens at 700, but only when there is no mortgage.
The exposure is high. The program allows at most 5 loans or $2,500,000 per borrower. Larger portfolios hit that limit.
Key Terms Defined
DSCR: the debt-service coverage ratio, gross monthly rent divided by the qualifying payment.
CLTV: combined loan-to-value, the first mortgage balance plus the new line, divided by property value.
Standalone second lien: a line recorded behind the first mortgage that leaves the first loan unchanged.
Draw period: the stretch, 5 years here, when the owner can draw funds and pays interest only on the drawn balance.
Stress payment: the fully amortizing payment on the entire limit, at the start rate plus 2 percentage points, used only for the coverage test.
How the Decision Looks in Practice
Run the numbers on a hypothetical single-family rental. The owner holds a low first mortgage, the property is held in an LLC, and the credit score sits at 735. First, add the first balance and the planned line, then divide by value. If the result is at or under 70%, the leverage clears. Next, test rent against the stress payment on the whole line. If coverage lands near 1.10x or better, the file is a candidate. If it lands under, shrink the line and test again.
Now flip it. Same owner, but the first mortgage is a high-balance loan and the line must be large. Combined leverage breaks the cap. The decision moves toward a cash-out refinance, or toward a smaller line, or toward waiting to pay the first balance down.
The stronger play often depends on what the money does next. Using a line to fund a down payment on a rental that covers itself is a clean use. Using it to cover a property that already runs thin on coverage is a warning sign about the property.
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.
What to Prepare
- The lease and a rent history for the property.
- The first mortgage statement, so the balance and payment are clear.
- Entity documents if the property is vested in an LLC.
- Current hazard insurance, plus flood coverage where required.
- Government ID and Social Security number for each guarantor.
The credit report and valuation are pulled by the lender. Underwriting still reviews credit, leverage, valuation and entity paperwork, so this is rent-qualified lending, not undocumented lending.
Frequently Asked Questions
Does a DSCR HELOC replace my first mortgage?
No. The line is written as a standalone second lien behind the first mortgage, which stays in place with its original terms. Some products in the market use the same nickname but pay off the first loan, so confirm the structure before applying.
Can an LLC hold title on the property?
Yes, through select programs on investment property, subject to underwriting. The LLC’s members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
How is the line tested if I draw only part of it?
The coverage test runs on the entire credit limit, not the drawn amount, at a stress payment. Rent must cover it at least 1.10x. A smaller line can improve the ratio, and the lender’s own calculation governs.
What if my score is below 720?
A second lien has no option below 720. A first-lien line on a rental with no mortgage opens at 700. Owners below those scores may look at other structures, such as a cash-out refinance, subject to lender guidelines.
Which states can use this program?
It is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, under Lendmire’s consumer licensing. Property and borrower eligibility rules still apply.
