The Quick Read: The right fit depends on where the old line sits in the lien stack, because a new rent-qualified line can replace an old line on the same rental only after that old line is paid off and formally closed, and the rent must still pass a stress test on the full new limit. No single program wins for every owner. Lendmire is a broker, so it matches the file to a wholesale lender whose rules fit the property, the equity, and the credit profile.
- Two paths cover most files. One is a new DSCR line that replaces the old line. The other is a DSCR cash-out refinance that retires the first mortgage and the HELOC together.
- The new line is never a third lien. It sits behind the first mortgage you keep, or stands alone as a first lien on a rental with no mortgage.
- Rent qualifies the line. Through select programs, the minimum coverage is 1.10x, tested on a payment sized to the entire credit limit, subject to underwriting.
- Combined leverage is the real limit. On a second lien, the first mortgage plus the new line can reach up to 70% CLTV at a 720 score or better.
- A HELOC on your own home cannot be retired this way. This line is never written on an owner-occupied home.
What Does “Refinancing a HELOC” Mean on a Rental?
It means one of three different moves, and mixing them up is a common source of confusion. Each move treats the old line, the first mortgage, and the rent test differently.
1. Replace the old line with a new rent-qualified line. The old HELOC is paid off and closed. The new line takes its place behind your first mortgage.
2. Roll everything into a DSCR cash-out refinance. A new first mortgage pays off the old first mortgage and the old HELOC. You get one loan and one payment.
3. Refinance the first mortgage and keep the old HELOC. This works only if the HELOC lender signs a written subordination, which keeps it behind the new first mortgage.
| Path | What happens to the old line | Revolving access after |
|---|---|---|
| New DSCR line | Paid off, closed, released | Yes, on the new line |
| DSCR cash-out refinance | Paid off inside new first lien | No |
| Refinance first, keep HELOC | Stays, if subordinated | Yes, on the old line |
Run all three before you pick. A more affordable-looking route on paper often fails on lien position or seasoning.
Which Property Secures Your Old HELOC?
This question settles more files than any rate discussion. The DSCR HELOC is secured only by a non-owner-occupied rental of one to four units. It is never a line on your own home or a second home.
- Old line on the same rental. A new line on that rental can replace it, once the old line is paid off and released.
- Old line on your primary home. Refinancing the rental does nothing to that lien. It stays exactly where it is.
- Old line on a different rental. That property has its own path. Its line gets handled when you refinance that property.
Check the recorded security instrument, not your memory. Many owners have drawn against one property and assumed the line sat on another.
How the Refinance Works, Step by Step
Think of it as a sequence of lien clean-up followed by a coverage test. The order matters.
1. List every lien. Write down the first mortgage balance, the old HELOC’s full credit limit (not only the drawn balance), and the property value.
2. Pick the path. Replace the line, roll it into a cash-out refinance, or seek a subordination.
3. Order a payoff letter. The payoff runs higher than your last statement, because interest builds daily.
4. Sign a closure request. A line at a zero balance is still a recorded lien until the lender formally closes it and records the release. Skip this step and the title company will not treat the lien as gone.
5. Run the coverage test on the new debt. The lender checks whether the rent covers the new qualifying payment.
6. Close through title. The title company pays off the old line, records the release, and funds the new one. Reconcile the settlement statement against the payoff letters line by line.
One classification point catches people off guard. Folding a HELOC payoff into a new DSCR first mortgage is generally treated as cash-out, even if no cash reaches you. A narrow exception exists in some programs where the line funded that very property’s purchase and carried no later draws. Lender guidelines decide it.
How Does the Coverage Test Treat the Whole Line?
The test uses the full credit limit, not what you owe. That surprises owners who carry a small balance on a big line.
The lender divides the rental’s gross monthly rent by a qualifying payment. That payment is fully amortizing and sized to the entire limit, at the start rate plus 2 percentage points. It is a stress payment, not the payment you will actually make. Across the wholesale network Lendmire places files with, programs of this type commonly set the floor at 1.10x. The lender’s own calculation governs, including how a first mortgage payment is treated on a second lien.
Rent counts as the lesser of two numbers: the appraiser’s market rent (Form 1007) or the signed 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.
Here is a worked picture, in percentages only. Say you own a rental, and your first mortgage equals 50% of its value while the old HELOC is drawn to 8% of value. With a 70% CLTV ceiling, the first mortgage plus the new line cannot exceed 70% of value. So the new line can reach at most 20% of value, and its closing draw pays off the old HELOC.
There is a catch. At least 80% of the new line, and never less than $50,000, must be drawn at closing. A small old balance therefore turns into a larger new balance. You borrow more than you owe today, and the stress test still runs on the whole limit. Size the line to the job, not to the maximum.
A DSCR HELOC qualifies the line primarily on property-level rental income covering the payment, subject to lender guidelines. Your tax returns, W-2s, pay stubs, and personal debt-to-income ratio do not enter the calculation.
What Do the Program Terms Look Like?
The figures below are typical ceilings and floors on select programs, subject to underwriting. They are not offers.
| Feature | Second lien | First lien (no mortgage) |
|---|---|---|
| Max leverage | 70% CLTV | 75% LTV (top tier) |
| Credit floor | 720 | 700 |
| Line size | $50,000 to $500,000 | To $1,000,000 |
| Larger lines | Not offered | 65% LTV above $500,000 |
On a first lien, the 75% LTV tier needs a 740 score or better on lines to $500,000. Scores of 700 to 739 on that same size carry up to 70% LTV. Lines above $500,000 sit at 65% LTV at 720 or better. A declining-market flag can lower these ceilings by 5 points. In Philadelphia, ceilings run 10 points lower. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Terms are the same across both lien positions:
- Draw period: 5 years, interest-only on the drawn balance.
- Repayment: 25 years, fully amortizing, with a 30-year maturity.
- Pricing: variable rate. The rate and pricing terms come with the lender’s HELOC disclosures.
- Later draws: at least $5,000 each.
- Reserves and cash to close: none required.

Eligibility and Seasoning: Stop Here If…
Check these before spending time on the rest. They knock out more files than leverage does.
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).
Other screens:
- Credit history. No 30-day mortgage late in the last 12 months. At least 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu.
- Borrowers. U.S. citizens, permanent residents, and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible.
- Exposure. At most 5 loans or $2,500,000 per borrower with the program.
- Property types. Single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums are eligible. Rural-designated property, row homes, condotels, leaseholds, land trusts, mixed-use property, age-restricted communities, and properties listed for sale in the prior 2 months are out. So is any property with a solar lien.
- Title. An LLC can hold title, subject to program terms. The members sign as guarantors.
- Valuation. Lines to $400,000 use an automated valuation (confidence score 85 or better) with a property inspection report, or a full interior appraisal. Larger lines need a full interior appraisal.
The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee.
Order of operations matters here. Refinancing your first mortgage resets the note-date clock, so doing that refinance first can push the new line out of eligibility for a while. Plan the sequence before you start either loan.
Where the General Rule Breaks
The old HELOC lender won’t subordinate. If you want to keep the old line and refinance the first mortgage, the new first-lien lender will not close with a second lien already ahead of it in line. As Point explains, the HELOC then has to be paid off or subordinated, and some HELOC lenders decline a resubordination request. Investment properties tend to be the hardest case. The fallback is paying off the line inside the refinance.
Your old line is nearing the end of its draw period. The CFPB notes that payments after the draw period are often significantly higher, and in some cases the full balance can come due once repayment begins. The FTC adds that a lender can foreclose if you don’t repay as agreed. That makes the end of a draw period a hard deadline. Ask your servicer about renewal or extension first, because replacing the line isn’t always necessary.
The rent covers the old structure but not the new one. A rental that clears the test comfortably on the old first mortgage may drop toward the 1.10x floor once a stress payment on a large new line is added. Not ideal. Shrinking the line, paying down the balance first, or choosing the cash-out path can all change the number.
You hold the rental in your own name but intend to live there part of the year. 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. Plan the occupancy honestly before you apply.
Your credit sits below the tier. Below 720, there is no second-lien option on this program. On a paid-off rental, a first lien starts at 700. A score in between those lines may point you toward a first-lien structure or a cash-out refinance instead.
The property type is excluded. A condotel, row home, or rural-designated property will not fit this line. That can leave the cash-out route as the only DSCR option, depending on that program’s own property rules.
What Makes a Program the Best Fit for This Job?
Skip any ranking. No honest list can rank programs without knowing your lien stack, and the best program for your situation changes with the file. Lendmire shops a file across the wholesale lenders it works with and matches the scenario. These are the criteria that decide the match:
- Lien position allowed. Does the program write a second lien behind your first mortgage, or only a first lien?
- Combined leverage at your score. Run the first mortgage plus the new line against the tier, not the line alone.
- Draw rules versus your balance. Will the 80% closing draw leave you borrowing far more than you owe?
- Property type and ownership. Check the excluded list and the LLC rules before anything else.
- Valuation path. The line size decides whether an automated valuation with an inspection report is enough or a full appraisal is required.
- Seasoning on your timeline. Match the 6-month clocks to your purchase and refinance history.
A good broker also tells you when the answer is “don’t replace the line.” More on that next.
When Is Replacing the Line Not Worth It?
Sometimes the old line works fine. Replacing it just resets seasoning, adds a mandatory draw, and re-tests the rent on a bigger number. Leave it alone when:
- The old line is not close to a repayment phase, and you can extend it.
- Your current balance is small, and the 80% closing draw would multiply it.
- The first mortgage is attractive and the old lender will subordinate.
- Your rent coverage is already tight.
Standby capital has real value, too. Many investors keep a revolving line open for down payments and rehab. Closing it in a cash-out refinance removes that option.
Which Route Fits Your Situation?
| Your situation | Likely fit |
|---|---|
| Old line on the same rental, first mortgage stays | New DSCR line |
| First mortgage unattractive, wants one payment | DSCR cash-out refinance |
| Old lender will subordinate, need new first | Refinance first, keep HELOC |
| Old line on your primary home | Separate problem; rental line won’t help |
| Score below 720 with a mortgage in place | Cash-out path or fix credit first |
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): Gross monthly rent divided by the qualifying payment. It shows whether the rental’s income covers its debt.
Stress payment: A fully amortizing payment on the entire credit limit at the start rate plus 2 percentage points. It is not the payment you actually make.
CLTV (combined loan-to-value): The first mortgage balance plus the new line, divided by the property’s value.
Lien position: The order in which loans get paid if the property is sold or foreclosed on. A second lien sits behind the first mortgage.
Subordination: A written agreement where the holder of an existing lien agrees to stay behind a new first mortgage.
Seasoning: The waiting period a lender wants after a purchase or refinance before the next loan.
Frequently Asked Questions
Can a DSCR HELOC pay off my old HELOC on the same rental?
Yes, once the old line is paid off and formally closed, subject to underwriting. The closing draw on the new line typically funds that payoff. The new line then sits behind your first mortgage, or stands alone as a first lien if the rental has no mortgage.
Does a zero balance on my old line mean the lien is gone?
No. A line at zero is still a recorded lien until the lender closes it and records the release. Ask for a closure request along with the payoff letter. Title will look for the release, not the balance.
Can I keep my old HELOC and still get a new DSCR line?
Not as a third lien. This program writes a standalone second lien behind your first mortgage, or a first lien on a rental with no mortgage. If the old line sits ahead of the new one, it has to be paid off or handled through a separate refinance first.
Does the lender look at my personal income?
No. The line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The lender still reviews your credit report, mortgage history, the lease, and the property valuation. Those are documented.
What if my old HELOC is on my own home?
This line cannot touch it. The program is never written on an owner-occupied home or a second home, and refinancing a rental does not release a lien on another property. Treat the two properties as separate files.
