The Quick Read: A new DSCR HELOC pays off the old line at closing, and the lender tests the rental’s rent, the combined leverage, your credit and the property itself. You do not document personal income. The rent has to cover a stress payment on the whole new line, not just the amount you draw, subject to lender guidelines and underwriting.
- The new line is a standalone second lien behind a first mortgage you keep, or a standalone first lien on a rental with no mortgage.
- The old line must be paid off at closing, so the new one never sits behind two other liens.
- Rent must cover a stress payment on the full limit at 1.10x or better.
- Second liens reach 70% combined leverage at a 720 score or better, on lines of $50,000 to $500,000, through select programs.
- Title and ownership rules matter as much as the rent, because of two six-month clocks and a list of excluded property types.
What “Refinancing a Balance Into a New HELOC” Actually Means
No separate product carries this name. Nobody sells a “HELOC-to-HELOC refinance.” What exists is a new line of credit on the rental whose closing draw pays off the old line. The old balance does not disappear. It moves into the new line, and the new line brings its own terms.
That distinction shapes everything else. The lender is not asking, “Can you carry this balance?” in the usual sense. It is asking whether this rental, as collateral and as an income producer, supports a brand-new line.
A DSCR HELOC is a revolving line of credit on a non-owner-occupied one-to-four-unit rental, qualified on the property’s rent instead of your personal income. DSCR stands for debt-service coverage ratio. Lendmire, a mortgage broker, places these lines through a wholesale lender in its network. The broker does not lend or approve, and every file is underwritten on its own.

Key Terms Defined
DSCR (debt-service coverage ratio): gross monthly rent divided by the qualifying payment. A result above 1.00x means rent exceeds the payment.
Qualifying payment: a fully amortizing principal-and-interest payment on the entire credit limit, at the start rate plus 2 percentage points. It is a stress test, not what you will actually pay. Taxes and insurance are not part of it.
CLTV (combined loan-to-value): the first mortgage balance plus the new line, divided by the property’s value. On a second lien, this is the leverage number that counts.
LTV (loan-to-value): the new line divided by value when it is the only lien. It applies to a first-lien line on a rental with no mortgage.
Lien position: your lender’s place in line to be repaid from the property. First lien is paid before second.
Draw period: the first 5 years of this program, when you pay interest only on what you have drawn. A 25-year repayment period follows, for a 30-year maturity.
Seasoning: the waiting period the lender wants after you buy or refinance a property before a new line is allowed.
How a Lender Qualifies the New Line
Underwriting checks five things in order of weight: rent against the stress payment, leverage, credit, the property, and the title. Personal income is not on the list. A DSCR HELOC qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
The rent test
The minimum DSCR is 1.10x. Here is the part that surprises most people: the payment in the test is calculated on the entire credit limit, not on the balance you plan to carry. A $300,000 line with a small drawn balance is still tested as if it were fully used. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
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. The appraiser documents market rent on Form 1007, the single-family rent schedule. A two-to-four-unit property may have at most one vacant unit.
Taxes and insurance do not enter the qualifying payment. Whether the first-mortgage payment joins the calculation on a second lien is something to confirm on your file, because the lender’s own coverage calculation governs.
The leverage test
Leverage depends on which lien position the new line takes. That depends on what sits on the rental today.
| Your rental today | New line | Leverage ceiling |
|---|---|---|
| First mortgage you keep | Second lien | 70% CLTV at 720+ |
| No mortgage | First lien | 75% LTV at 740+ |
| No mortgage | First lien | 70% LTV at 700-739 |
| No mortgage, line over $500,000 | First lien | 65% LTV at 720+ |
Second-lien lines run from $50,000 to $500,000. First-lien lines run to $1,000,000. These are ceilings, not offers. A declining-market flag on the property lowers the ceiling by 5 points. All figures are subject to underwriting.
Credit and borrower rules
The minimum score is 720 on a second lien and 700 on a first lien, taken from the lender’s own credit report. The lender wants no 30-day mortgage late in the last 12 months. It also wants 48 months since a bankruptcy, foreclosure, short sale or deed-in-lieu. No reserves and no cash to close are required.
Eligible borrowers are US citizens, permanent residents and non-permanent residents with a Social Security number. Foreign nationals and ITIN borrowers are not eligible on this program. Each borrower can hold at most 5 loans or $2,500,000 with the program.
An LLC can hold title, subject to program terms. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument.
Which Old Line Do You Have?
The answer to “can I do this?” starts with the old line’s lien position and which property secures it.
| Old line sits on | What happens | Fit |
|---|---|---|
| This rental, behind a first mortgage | Paid off; new line takes second | Usually works |
| This rental, as the only lien | Paid off; new line is first lien | Usually works |
| Your own home | Different, owner-occupied product | Not this program |
| A different rental | Separate property, separate file | Needs its own review |
The first two rows are the real use case. Both rest on the same rule: the old line must be paid off at closing. If it stayed open behind the first mortgage, the new line would be a third lien, and this program does not write third liens.
The third row is a trap. A line on your own home is a primary-residence product. This program is never offered on an owner-occupied home or a second home, so it cannot take over that lien.
Lien Position and Payoff, Explained Plainly
Think of liens as a line of creditors. The first mortgage lender is at the front. If you keep that mortgage, your new line takes the second spot. The old HELOC cannot stay in the line, so it gets paid off from the closing draw.
At least 80% of the new line is drawn at closing, and the closing draw is never less than $50,000. On the smallest lines, that means the whole line is drawn at closing. Later draws must be at least $5,000 each. This helps in a payoff, because the closing draw is where the old balance gets cleared.
It also creates a sizing problem. The new line has to be large enough that its closing draw covers the payoff. But the qualifying payment is tested on the whole limit, so a bigger line is a harder test. The tension between those two facts is where most of these files get decided.
The lender also checks title to confirm the payoff and the lien order. A full title policy is required on a first lien and on second liens above $400,000. Smaller second liens use an owner-and-encumbrance report.
A Worked Example
These figures are modeled assumptions, not market data. The lender’s own calculation governs.
Say you own a duplex held in your LLC. A first mortgage sits at about 50% of the property’s value. An old HELOC takes up roughly another 10%. Your score is 735, and the lease and the appraisal’s market rent line up.
You are replacing the old line with a new second-lien line. Because the first mortgage stays, CLTV is the test. The ceiling at your score is 70%, so the first mortgage plus the new line cannot exceed 70% of value. That leaves up to 20% of value for the new line.
Now the rent test. The lender takes the lesser of lease and market rent, then divides by the stress payment on the full 20%-of-value limit, unless three months of rent receipts support a lease above market. Say that works out to about 1.25x. It clears the 1.10x minimum, and the deal works forward.
Change one input and the picture flips. If coverage came out around 1.05x, the file falls short. A smaller line lowers the stress payment, because the payment is calculated on the limit. A line sized only slightly above the payoff can bring the ratio back above 1.10x. Documentation also matters: three months of receipts can support a lease above market rent.
Now a first-lien version. Your score is 735, the rental has no mortgage, and the old HELOC is the only lien, at about 45% of value. The tier for 700 to 739 is 70% LTV on lines up to $500,000. A new first-lien line up to 70% of value would pay off the old balance with room to spare. Your score is below the 740 needed for the 75% tier, so the lender caps you at 70%. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Valuation and Property Rules
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 (Form 1004, 1073 or 1025). Appraisal waivers are not accepted.
Eligible property types include single-family, PUD, townhome, two-to-four units, and warrantable and non-warrantable condominiums. Lots up to 10 acres are also eligible. These property types have no separate leverage figure; the tiers above govern every type.
These are outside the program: rural-designated property, row homes, condotels, commercial or agricultural property, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, land contracts and mixed-use property. A property listed for sale in the prior two months is out, and so is one with a solar lien. Hazard insurance must cover both liens, with flood coverage where required.
Seasoning: The Two Six-Month Clocks
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 your old HELOC was recent, raise its note date with the lender at the start. Do not assume it falls outside the clock.
Step by Step: From Your Lien List to Closing
1. List every lien on the rental. Get the first mortgage balance and the old HELOC’s full payoff figure.
2. Pick the lien path. First mortgage stays, so second lien. No mortgage, so first lien. A 700 to 719 score only fits a first lien on a rental with no mortgage.
3. Check the exclusions. Run the property against the ineligible list, and check the two six-month clocks.
4. Test the numbers. Combined leverage first, then rent against a stress payment on the whole line.
5. Gather documents. The lease, rent receipts if you rely on them, your entity papers if an LLC holds title, the first mortgage statement, and the old line’s payoff details.
6. Order the valuation and title work. The lender picks the path based on the size of the line.
7. Close with the payoff. The old line is paid from the closing draw, and the new 5-year interest-only draw period begins.
When This Does Not Work
Stop and rethink if any of these apply:
- Rent covers the stress payment at less than 1.10x, even after sizing the line down.
- The first mortgage plus the new line would exceed 70% CLTV.
- Your score is below 720 and the rental already carries a first mortgage.
- The rental is rural, a row home, a condotel or sits on a leasehold.
- The property was bought or refinanced in the last 6 months.
- A second unit in a duplex or larger is vacant.
Some of these are fixable. A smaller line or three months of receipts may help a weak ratio. Others are structural, and a different loan fits better.
Risks of a Variable-Rate Line
Resetting into a new line means a fresh draw period, which can feel like relief. The cost is that you carry a variable rate and payment exposure again. The CFPB’s HELOC explainer describes a HELOC as an open-end line, typically with a variable rate. It also notes a lender can stop further credit if the home’s value drops significantly.
The CFPB’s HELOC brochure adds that an interest-only draw means you pay no principal during that period. It also says payments can change even when you do not draw. The program’s rate and pricing terms come with the lender’s HELOC disclosures, so compare those before committing.
New HELOC, Cash-Out Refinance or Something Else?
| Option | Best when | Trade-off |
|---|---|---|
| New DSCR HELOC | You want to keep a good first mortgage | Variable rate; whole-limit stress test |
| DSCR cash-out refinance | You want one fixed-structure loan | Replaces the first mortgage |
| Personal-income investment HELOC | Your income file is strong | Tests your income and debts |
The personal-income HELOC follows that program’s rules, not this one.
The deciding factors are usually the first mortgage and your entity. If your first mortgage is one you want to keep, a second-lien line protects it. If you are holding title in an LLC, a rent-qualified line avoids the personal-income file that many bank products require.

Frequently Asked Questions
Does the new HELOC wipe out my old balance?
No. The new line pays off the old line at closing, and the balance moves into the new line. You are replacing one debt with another, so the real decision is about structure and cost. The closing draw covers the payoff.
How is the line tested if I only plan to draw part of it?
The lender tests the full limit, not the drawn amount. The qualifying payment is a fully amortizing principal-and-interest payment on the entire line at the start rate plus 2 percentage points. A smaller line lowers the test.
How soon after buying or refinancing can I qualify?
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).
Can my LLC hold title on the rental?
Yes, an LLC can hold title on an investment property, subject to program terms. The members sign as guarantors.
What if my score is between 700 and 719?
A second lien needs 720, and this program has no second-lien tier below that. A 700 to 719 score fits only a first-lien line on a rental with no mortgage. Both tiers are subject to underwriting.
