The Quick Read: A DSCR HELOC sits behind the first mortgage you keep as a standalone second lien, so the original loan, its terms and its payment stay exactly as they are, while a new revolving line qualifies primarily on the rental’s income covering the payment, subject to lender guidelines, and draws on the equity that remains. The line is written on a non-owner-occupied one-to-four-unit rental, and the LLC can stay on title. It runs through select programs in Lendmire’s wholesale network.
- The first mortgage is untouched. Nothing is paid off, replaced or re-papered.
- Combined loan-to-value (CLTV) on a second lien behind your first mortgage is typically capped at 70%, at a 720 credit score or better, on lines of $50,000 to $500,000.
- The rent has to cover a stress payment on the whole line at a minimum 1.10x, and no traditional personal-income documentation, W-2s or personal income calculation are needed.
- Most of the line is drawn at closing, so it works as a funding tool, not a reserve account.
What Is a DSCR HELOC on a Rental?
It is a revolving line of credit secured by a rental you already own. It is written as a standalone second lien behind the first mortgage you keep. If the rental has no mortgage, it can be written as a standalone first lien.
Three things it is not. It is not closed together with a purchase. It is not a third lien. It is not a line on your own home or a second home.
The “DSCR” part means the rental’s income, not yours, drives lender review. Gross monthly rent is divided by a qualifying payment, and the result is the debt service coverage ratio. The complete DSCR loans guide covers the ratio for readers new to it.
One warning on the label. “DSCR HELOC” is a market name, not a standard product. Some offers sold under it are closed-end seconds that pay out a single lump sum. Others pay off the first mortgage. Ask each time whether the line is revolving, whether it sits behind the existing loan, and whether the first loan stays in place. Across Lendmire’s wholesale network, the program described here is revolving and leaves the first mortgage alone.
What Happens to the Original Loan?
Nothing happens to it. The first mortgage keeps its balance, its terms, its servicer and its payment. The line adds a second loan with its own payment and its own servicing.
| Item | Original first mortgage | New DSCR HELOC |
|---|---|---|
| Lien position | Stays first | Added behind it |
| Terms and payment | Unchanged | Separate, variable rate |
| Servicer | Unchanged | Separate |
| Borrowers | As signed | May differ from the first loan |
| Qualifying basis | Already closed | The rental’s rent |
That is the main reason investors choose this structure. A DSCR cash-out refinance replaces the first mortgage, so the first loan’s terms are lost. A second lien lets the investor keep a first mortgage worth keeping and borrow only against the gap.
The line is a new debt on the same property. The rental now carries more debt, and the rental itself secures the line. Plan for two payments, not one.
How Does Underwriting Treat the Line With the First Loan in Place?
Underwriting reads five things: equity headroom, coverage, credit, valuation and title. Each one is tested against the line, not against the first loan alone.
1. Pick one rental. The line is secured by one property. Equity does not pool across several rentals.
2. Confirm lien position. A second lien sits behind the first mortgage you keep. A first lien applies only if the rental has no mortgage.
3. Run the CLTV test. CLTV is the first-mortgage balance plus the new line limit, divided by value. The full limit counts, drawn or not. On a second lien behind a first mortgage on a non-owner-occupied rental, the ceiling is typically 70% CLTV, subject to underwriting. If the first mortgage sits at 50% of value, headroom is about 20% of value, and the whole line has to fit inside it.
4. Test coverage. The program looks for at least 1.10x. Gross monthly rent is divided by a stress payment, which is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. Rent counts at the lesser of the appraiser’s Form 1007 market rent or the lease. A lease above market counts with three months of receipts. A lease in place is required. A two-to-four-unit property may have at most one vacant unit. On a second lien, whether the first-mortgage payment also enters the qualifying payment is not published. The lender’s own coverage calculation governs, so do not size a file on an assumed formula.
5. Credit, valuation and title. The tier is the lender’s own credit report. There should be no 30-day mortgage late in the last 12 months. Time since a bankruptcy, foreclosure, short sale or deed-in-lieu typically needs to be 48 months. For lines up to $400,000, valuation is an automated valuation with a confidence score of 85 or better plus a property inspection report, or a full interior appraisal. Above $400,000 it is a full interior appraisal (Form 1004, 1073 or 1025). Appraisal waivers are not accepted. Title is a full policy on a first lien and on second liens above $400,000. Smaller seconds use an owner-and-encumbrance report.
No reserves and no cash to close are required, subject to underwriting. Hazard insurance has to cover both liens, with flood coverage where required.
The coverage number is a qualifying test, not a cash-flow promise. A line can pass at 1.10x and still leave thin cash flow once both payments are running.
Does the First Mortgage Allow a Second Lien?
Usually yes, and federal law backs that up for small residential properties. Still, read your own note before you commit.
The worry is the due-on-sale clause, which lets a lender call the loan if the property transfers. A second lien is not a transfer. The federal statute, 12 U.S.C. §1701j-3, bars a lender from enforcing a due-on-sale clause when a subordinate lien is created that does not involve a transfer of occupancy rights. Bankrate gives the same practical read: a lender typically can’t enforce the clause when a borrower takes a second mortgage.
The statute’s text is clearest on residential property of fewer than five units, which is where this program lives. It does not cover every note.
Run this checklist before applying:
- Read the junior-lien and due-on-sale language in your first-mortgage note.
- If the first loan is a DSCR or other non-QM loan, read it twice. Those notes are written by different lenders and vary more.
- Ask the first-mortgage servicer how it handles a recorded second lien.
- Talk to a real estate attorney if the language is unclear.
The borrowers on the line do not need to match the borrowers on the first mortgage. If someone is on title but not on the line, they sign a non-borrowing owner acknowledgment and the security instrument. The line also does not remove anyone from the original note. A buyout or divorce is a separate problem.
Key Terms Defined
Second lien: a loan recorded behind the first mortgage, paid after it if the property is sold or foreclosed.
CLTV (combined loan-to-value): the first-mortgage balance plus the full new line limit, divided by the property’s value.
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment, with 1.10x the minimum on this program.
Stress payment: the payment used for qualifying, a fully amortizing payment on the whole line limit at the start rate plus 2 percentage points. It is not the payment you make during the draw period.
Draw period: the first 5 years, when payments are interest-only on the drawn balance. Repayment follows over 25 years, for a 30-year maturity.
Seasoning: the required time since the rental was bought or refinanced, and the time you have held title.
How Does the Line Work Day to Day?
At least 80% of the line is drawn at closing, and never less than $50,000. Later draws are at least $5,000 each. The rate is variable.
Payments during the draw period are interest-only on the drawn balance. After 5 years the line moves to a 25-year fully amortizing repayment period. The CFPB warns that HELOC payments often rise sharply when repayment starts, and that in some cases the whole balance can come due. Plan for the amortizing payment from day one, not just the interest-only one.
The line is a poor emergency fund. Most of it is drawn at closing, and a lender may reduce an undrawn balance. Use it for a defined purpose: a down payment, rehab, or paying off higher-cost debt.
The rate and the pricing terms come with the lender’s HELOC disclosures. Read them. A variable rate can move, and the payment moves with it.
Where the General Rule Breaks
Most surprises come from a handful of edge cases.
Credit below 720. There is no second-lien option. A first-lien line is possible only on a rental with no mortgage, and its floor is a 700 score.
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).
Already two liens. The line is never a third lien. A rental with a first and a second is out of scope.
LLC title. Vesting in the owner’s LLC is allowed on an investment property, depending on program guidelines. The members sign as guarantors.
Ineligible property. Eligible types include single-family, PUD, townhome, two-to-four units, warrantable and non-warrantable condominiums, and lots to 10 acres. Not eligible: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts, mixed-use, a property listed for sale in the prior 2 months, and a property with a solar lien. A declining-market flag lowers the ceiling by 5 points.
Former residence. The line is never written on an owner-occupied home. A former home qualifies only if it is a true non-owner-occupied rental with a lease in place.
Borrower type. US citizens, permanent residents, and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not.
Portfolio size. The program allows at most 5 loans or $2,500,000 per borrower.
First-lien leverage. On a standalone first lien on a rental with no mortgage, LTV tops out at 75% at 740 or better, on lines to $500,000. It is 70% from 700 to 739. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. Second-lien limits never exceed 70% CLTV. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Using the line for a down payment. This works as two separate files. The line must close first. The purchase lender then has to accept borrowed funds as a down-payment source, and cash moves through your own account. On most files, the new purchase’s coverage ratio reads that property’s own payment, not the line payment, though individual purchase lenders differ.
What About a Later Refinance or Sale?
A sale pays off both liens from proceeds. A later refinance of the first mortgage is the harder case.
If you refinance the first loan, the new first has to sit ahead of the line. That usually requires the line holder to agree to stay in second position, which is called subordination. Ask about it before you refinance, not after.
Leaving the first loan in place generally does not trigger its payoff terms. Any prepayment schedule or exit fee in your first note is a separate matter. Read it if you plan to sell or refinance early.
How Does It Compare to the Alternatives?
| Option | First mortgage | Qualified on |
|---|---|---|
| DSCR HELOC (second lien) | Kept | Rental income |
| DSCR cash-out refinance | Replaced | Rental income |
| Investment HELOC, borrower-underwritten | Kept | Personal income |
| Closed-end DSCR second | Kept | Rental income |
A DSCR cash-out refinance replaces the first mortgage and its terms. That program is a different product with its own rules.
The investment-property HELOC underwritten on personal income is also a different Lendmire product. Its rules differ: a 700 minimum score, a 70% CLTV ceiling, a $500,000 cap, a 50% debt-to-income ratio, and title in a personal name or revocable trust, with no LLC. Do not mix those figures with the DSCR line.
NerdWallet notes that not all lenders offer a HELOC on an investment property, that requirements are stricter because lenders see higher default risk, and that multiple appraisals may be required. Many big banks simply decline rentals. That gap is where rent-qualified lines fit. The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee: Alabama, California, Colorado, Florida, Georgia, Indiana, Michigan, Montana, New Mexico, North Carolina, Ohio, Pennsylvania, Texas, Virginia and Washington.
When Is This the Right Tool?
It fits when four things line up. The first mortgage is worth keeping. The rent covers the stress payment on the full line. The CLTV headroom is real. You have a specific use for the cash.
It is the wrong tool when the first loan is a poor one you would refinance anyway, when you want a reserve you can leave undrawn, or when credit sits below 720 on a rental that carries a mortgage.
Picture an investor with a rental well below the 70% ceiling and a first mortgage worth keeping. The rent clears 1.10x against the full stress payment. A line sized to the headroom funds the next down payment without touching the first loan. Now flip it. The same investor needs cash on a rental already near the ceiling. The test fails, and no coverage ratio fixes a CLTV problem.
The strongest play often depends on the first loan’s terms. If they are worth keeping, a second lien wins. If not, a cash-out refinance may serve better, a call that comes down to the numbers on each file.
Frequently Asked Questions
Will a DSCR HELOC trigger the due-on-sale clause on my first mortgage?
Generally not. Federal law bars enforcement of a due-on-sale clause when a subordinate lien is created without a transfer of occupancy rights. The statute is clearest for residential property under five units. Read your own note and ask an attorney if the wording is unusual.
Does the first-mortgage payment count in the coverage test?
The program does not publish how the first payment enters the coverage test on a second lien. The lender’s own calculation governs. The qualifying payment itself is a stress payment on the whole line limit, and the minimum ratio is 1.10x.
Can I use the line as an undrawn reserve?
It is a poor fit. At least 80% of the line is drawn at closing, and a lender may reduce an undrawn balance. Treat it as funding for a defined purpose.
Can an LLC hold the property?
Yes, subject to lender program eligibility. The members sign as guarantors, and a title holder who is not a borrower signs an acknowledgment and the security instrument.
Does the line payment hurt my next DSCR purchase?
On most files, the new purchase’s coverage ratio reads that property’s own payment, not the line payment. Individual purchase lenders can differ, and the purchase lender has to accept the funds source.
