The Quick Read: It depends on which property secures the old line, because it makes sense when the existing HELOC sits on a rental you own, the rent covers a stress payment on the whole new line, and the lien order works, but it does not make sense when the old line is on your own home. A DSCR HELOC is a rent-qualified line of credit on a non-owner-occupied rental. It is written as a standalone second lien or a standalone first lien, so it replaces the old line instead of sitting beside it.
- The old HELOC must be secured by the rental itself. A line on your primary home cannot be paid off this way.
- The new line is tested on rent against a stress payment on the entire credit limit, not just the drawn balance.
- A second lien tops out at 70% combined loan-to-value (CLTV). A first lien on a rental with no mortgage reaches 75% loan-to-value (LTV) at the top credit tier on lines up to $500,000, and 65% LTV on lines above $500,000.
- A DSCR cash-out refinance into a new first mortgage is the other route, and it gives up the first mortgage you may want to keep.
What Does a DSCR HELOC Actually Replace?
A DSCR HELOC replaces a bank-written line on a rental with a line that the rental’s rent qualifies. Across the wholesale network where Lendmire places these files, the structure is consistent. The line is a revolving second lien behind the first mortgage you keep, or a first lien on a rental that has no mortgage. It is never a third lien, and it is never a line on your own home.
The label causes confusion because “DSCR HELOC” is a naming shortcut, not a single standard product. Some lenders use it for a rent-qualified cash-out refinance. Others use it for a closed-end second mortgage. The program discussed here is a revolving line, so the draw rules matter.
The rent qualifies the line, not your pay stubs. Qualification runs on property-level rental income covering the payment, subject to lender guidelines. No traditional personal-income documentation, W-2s or personal income calculation enter the file. If you are new to the underlying product, Lendmire’s complete DSCR loans guide covers how coverage ratios work in general.
Vesting in your LLC is allowed on an investment property, subject to lender program eligibility. The members sign as guarantors. This matters because many bank lines are written only to individuals, and that is often why investors with entity-titled rentals look for another route.
Which Property Secures Your Old HELOC?
This is the question that decides everything. The new line must sit on the same rental the old line sits on, and the rental must be a non-owner-occupied one-to-four-unit property.
| Old HELOC secured by | Can this program replace it? | Usual path |
|---|---|---|
| The rental itself | Yes, if the rental is eligible | New line pays off and closes the old one |
| Your primary home | No | Pay it down or renew it separately |
| A different rental | Only on that rental’s own file | Run coverage on that property |
If the old line is on your home, the new line cannot touch it. The program never lends against an owner-occupied home or a second home. You could draw cash from a qualifying rental and use it to pay down the home line yourself. That is a separate decision, and it adds debt to the rental. Weigh it as new borrowing, not as a swap.
If the old line sits on a rental you own free and clear, the new line can be a first lien. If the old line sits behind a first mortgage you plan to keep, the new line is a second lien. In either case the old line has to be paid off and closed at the new closing. A new line is never placed behind another second lien.
For the mechanics of paying off an old line with a rent-qualified one, see Lendmire’s piece How to Use an Investment Property HELOC to Refinance an Existing HELOC Into a DSCR Loan.
Why Do Investors Want Out of the Old Line?
The usual trigger is the structure of the old line, not the balance. A bank HELOC is underwritten on the borrower, so it is only as steady as the borrower’s file and the bank’s appetite. Investors with several rentals, LLC titles or a high debt-to-income ratio run into limits fast.
The payment profile is the second trigger. The CFPB’s HELOC brochure explains that HELOCs typically carry variable rates and that payments can change even if you draw nothing more. It also describes a draw period that ends and gives way to a repayment period. Experian’s explainer on draw periods adds that draw and repayment lengths vary by lender and that some lines carry a balloon. A balloon means the whole balance can come due at once.
That reset is the moment many investors start shopping. An interest-only payment can turn into a fully amortizing one. The rent that covered the old payment may not cover the new one.
The DSCR HELOC does not remove that reset. It has its own: 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. So the swap gives you a known schedule at the outset and a review based on the property’s rent, but not a fixed payment.
Three Paths Side by Side
Three routes usually compete. Which one wins depends on whether your existing first mortgage is worth keeping.
| Factor | DSCR HELOC replaces old line | DSCR cash-out refinance | Keep old line as is |
|---|---|---|---|
| First mortgage | Stays in place if you have one | Paid off and replaced | Stays in place |
| Old HELOC | Paid off and closed | Paid off with proceeds | Stays open |
| Payment type | Variable, interest-only draw period | Set by that program | Set by your bank |
| Qualification | Rent covers stress payment | Rent-based, own guidelines | Your personal file |
| Best for | Keeping a low first mortgage | Wanting one loan and one lien | A line that still works |
A DSCR cash-out refinance into a new first mortgage is a separate program with its own leverage and seasoning rules. A few investors prefer it because it gives one lien and one payoff. But it discards the terms of the first mortgage you already hold. If that first mortgage is cheap, rolling it into a new loan can cost more than the second lien ever would.
For contrast, agency cash-out refinances work differently. Fannie Mae’s Selling Guide requires the existing first mortgage to be at least 12 months old on a cash-out refinance. That is the agency’s rule, and it does not govern this program.
Replacing a first mortgage can also trigger a prepayment charge if the existing loan carries one. Check the note before you choose the cash-out route. A second lien leaves the first mortgage untouched, so that cost never arises.
How the Coverage Test Works on the New Line
The line must show a DSCR of at least 1.10x, measured as gross monthly rent over the qualifying payment. That payment is a fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is a stress payment, built to test the line at a harsher rate than the one you will start with.
Three details change the answer for a refinance.
- The whole limit counts. The test runs on the full line, not on the drawn balance. A large line sized for future projects can fail even when the amount you need today is small.
- Taxes and insurance are not in the qualifying payment. It is principal and interest on the full line at the stress rate. They still hit your real cash flow, so coverage and cash flow are different things.
- Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. A two-to-four-unit property can have at most one vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment in its coverage calculation. The lender’s own calculation governs.
Leverage depends on the lien. On a second lien, CLTV (the first mortgage balance plus the new line, divided by value) reaches 70% at a 720 credit score or better, on lines up to $500,000. Below 720 there is no second-lien option. A first lien exists only on a rental with no mortgage: it reaches 75% LTV at 740 or better and 70% LTV from 700 to 739 on lines up to $500,000. On lines above $500,000, up to $1,000,000, a first lien is capped at 65% LTV at 720 or better. All of this is subject to underwriting. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Lines start at $50,000. At least 80% of the line is drawn at closing, and the closing draw is never less than $50,000. Later draws are at least $5,000 each. This draw rule is the part refinancers often miss. Size the new line so that the payoff of the old balance and the required closing draw roughly line up. Any draw above the payoff lands in your account as new debt. Don’t oversize the line just because the limit is available.
Does the Age of Your Old HELOC Matter?
Yes, because two six-month clocks apply to the rental. 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).
If you opened the old HELOC recently, confirm on the file whether it affects the note-date side of that test. A line opened on a rental you have owned for years is the cleanest case.
What Does the File Need?
The file is built from documents about the property and the credit, not your income.
- Credit: 720 minimum on a second lien, 700 on a first lien. There should be no 30-day mortgage late in the last 12 months. At least 48 months should have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
- Valuation: lines up to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
- Cash and reserves: the program requires no reserves and no cash to close. The closing draw is a separate matter, covered with the draw rules above.
- Exposure: at most 5 loans or $2,500,000 per borrower with the program.
- Borrowers: U.S. citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
Several property types fall outside it: rural-designated property, condotels, row homes, leaseholds, and a property listed for sale in the prior 2 months. If your rental is one of those, the swap is off the table before coverage matters.
Two Worked Cases
Both cases use ratios and percentages, not payment figures. The lender’s own calculation governs in every case.
A case where it makes sense. Picture an investor holding a duplex with no first mortgage and an old bank HELOC as the only lien. The investor’s credit score is 745, the bank line sits in an individual’s name, and the investor wants to move the duplex into an LLC. The rent clears the 1.10x test on a stress payment across the whole new limit, with coverage near 1.2x. The leverage target is 75% LTV on a first lien. The new line pays off and closes the old one, and the rental now carries a rent-qualified first lien in the LLC. A lender would review the file against its guidelines, but this is the shape the program is built for. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
A case where it does not. Say an investor owns a fourplex with a first mortgage worth keeping and an old HELOC behind it as a second lien. The credit score is 705. A second lien needs 720, so the new line is out of reach. Coverage is also near 0.95x across the whole limit, below the 1.10x test. The structures a lender would review here are a smaller line, paying the old line down, or a DSCR cash-out refinance under its own rules. Chasing the line anyway is the wrong move. When rent can’t carry the stress payment, the property’s yield is the problem, not the loan type.
Both cases come down to the same three checks: lien position, coverage across the full limit, and leverage after the existing first mortgage.
When It Does Not Make Sense
Skip the swap in these situations.
- The old line is on your home. This program cannot pay it off.
- The rent cannot carry the stress payment on the full limit. A smaller line or a different structure fits better.
- The old line is small or idle. The new line starts at $50,000, and at least 80% is drawn at closing. Borrowing more than you need to replace a small balance adds cost.
- The rental is an excluded type. Condotels, row homes, rural-designated property and the other exclusions above are out.
- Your credit score is under 720 and you keep a first mortgage. The second-lien tier is not available.
- The old line still works. If it is fully serviceable and its payment is comfortable, a swap just adds closing steps.
This is a genuine toss-up for investors with a healthy bank line and a rising pile of rentals. The bank line works until the bank decides it doesn’t. A rent-qualified line does not depend on the bank’s view of your personal income. The cost is a new closing and a new variable-rate line. Weigh both before deciding.
A Pre-Application Checklist
1. Pull the old HELOC agreement and confirm which property secures it.
2. Check the old line’s credit limit, not just the balance. The limit counts as exposure in many files.
3. List every lien on the rental and its payoff amount.
4. Compare the rent to the stress payment on the entire new limit. Use the lesser of market rent and the lease, unless three months of rent receipts support a lease above market.
5. Confirm the rental is an eligible property type, owner title and seasoning meet the program’s clocks, and the credit tier matches the lien you want.
6. After closing, ask the old lender for written closure and a recorded lien release. A zero balance alone does not close a line.
Key Terms Defined
DSCR: The debt-service coverage ratio, meaning gross monthly rent divided by the qualifying payment.
CLTV: Combined loan-to-value, meaning the first mortgage balance plus the new line, divided by the property’s value.
Stress payment: The fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points, used only to test coverage.
Draw period: In this program, the first 5 years of the line, during which the payment is interest-only on the drawn balance.
Subordination: A junior lender’s agreement to stay behind a new first lien.
Lien release: The recorded document that proves a line is closed and no longer secures the property.
Frequently Asked Questions
Does my old HELOC payment count against the new line’s coverage?
No, because the old line is paid off and closed at the new closing, so its payment leaves the picture. The test runs on rent against the stress payment on the whole new limit. On a second lien, confirm on the file how the lender treats the first-mortgage payment.
Can I use this to pay off a HELOC on my own home?
No. The line is only written on a non-owner-occupied rental, never on your own home or a second home. You could draw cash from a qualifying rental and pay the home line yourself, but that is new debt on the rental, so run the coverage before you decide.
How old does the rental or the old HELOC have to be?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). If the old HELOC was opened recently, ask how the lender reads that against the first clock.
Can my LLC hold the new line?
Yes, an LLC can hold title on an investment property, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Should I take a DSCR HELOC or a DSCR cash-out refinance?
It turns on your first mortgage. If it is worth keeping and your score is 720 or better, the second-lien line leaves it alone. If the first mortgage has weak terms or you want one lien and one payoff, a cash-out refinance fits better. The two products have different leverage and seasoning rules, so compare them on the same property.
