The Quick Read: It depends on what secures the old line, because a new DSCR HELOC can pay off an old line only when the collateral is a rental you own and the new line ends up in first or second position, subject to underwriting. A line on your own home cannot be moved this way.
- The new line is written as a standalone first lien on a rental with no mortgage, or a standalone second lien behind a first mortgage you keep.
- The rent qualifies the line at a minimum 1.10x coverage on a stressed payment across the whole limit. Your personal income is not calculated.
- At least 80% of the line is drawn at closing, so the old balance and the new draw must fit together.
- A rental bought or refinanced in the last 6 months is not eligible, so the age of the old line matters.
What Does “Refinancing a Balance Into a New HELOC” Actually Mean?
It means a new line of credit is opened on the same rental, and its first draw pays off the old line. The old line is closed and its lien is released. The balance does not disappear. It moves into a new line with its own terms.
A DSCR HELOC is a revolving line secured by a non-owner-occupied one-to-four-unit rental. It is reviewed on the property’s rent instead of the owner’s tax returns, pay stubs or debt-to-income ratio. Lendmire is a mortgage broker, and it arranges this product through a wholesale lender in its network. The lender reviews and approves each file individually.
The rent and the lease are documented. So are the credit report and the valuation. The difference is that the property’s income carries the qualification, not yours. If you want the broader picture of how rent-based lending fits together, Lendmire’s complete DSCR loans guide covers it.
Key Terms Defined
DSCR (debt service coverage ratio): monthly rent divided by the qualifying monthly payment, which shows whether the property’s income covers its debt.
Combined loan-to-value (CLTV): all liens on the property, including the new line, divided by the property’s value.
Lien position: the order in which lenders get repaid from the property. A first lien comes ahead of a second lien.
Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
Seasoning: how long you have owned or refinanced the property before a new loan is allowed.
Vesting: how the property is titled, whether in your name or in an LLC.
Which Structure Fits Your Old Line?
The right structure follows the lien the old line sits in. Three situations come up most often, and a fourth is simply not available. This table sums them up.
| Your situation | New structure | What changes |
|---|---|---|
| Old line is the only lien on the rental | Standalone first lien | Old line paid off at closing |
| Old line is a second lien behind a mortgage you keep | Standalone second lien | Old second paid off, so the new one is never third |
| You want to merge the mortgage and the line | DSCR cash-out refinance | One new loan replaces both |
| Old line is on your own home | Not this program | A different, owner-occupied product |
A new second lien is never written as a third lien. If your rental already has a first mortgage and an old line, the old line has to be paid off at closing for a new second lien to sit behind that mortgage. The first mortgage stays untouched, which is why investors with a low-rate first mortgage often prefer this route.
How the Old Balance Counts Against Leverage
The old balance matters because it sets how much room the new line needs. On a second lien, combined loan-to-value runs up to 70% at a 720 credit score or better, on lines from $50,000 up to $500,000. That figure counts the first mortgage balance plus the new line, divided by value. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
On a first lien, the ceilings are higher but depend on credit and size. Loan-to-value reaches up to 75% at 740 or better on lines up to $500,000. It is 70% for scores from 700 to 739. Lines above $500,000 run to $1,000,000 and carry a 65% ceiling at 720 or better. All of these are subject to underwriting, and a declining-market flag can lower the ceiling by 5 points.
The 80% draw rule shapes the sizing. At least 80% of the line, and never less than $50,000, is drawn at closing. Later draws are at least $5,000 each. Say your old balance is only half the limit you would like. The program still requires most of the line drawn, so you would take cash beyond the payoff, and you would pay on all of it.
Most borrowers underestimate this. A lender will not let you open a large line and leave it idle. The better approach sizes the limit near the balance you really want to carry.
Does the Rent Still Qualify It?
Yes, but the test is stricter than the headline suggests. The minimum coverage is 1.10x. Gross monthly rent is divided by a fully amortizing payment on the entire credit limit, run at a stressed level above the starting terms. The test covers the whole limit, not only the drawn balance.
Rent is the lesser of the appraiser’s Form 1007 market rent and the lease. A lease above market counts only with three months of receipts. A lease in place is required. A two-to-four-unit property can have at most one vacant unit.
On a second lien, the lender’s own coverage calculation governs how the first mortgage payment is treated, so do not assume a formula. Ask for the exact method before you size the line. A rental that clears 1.10x on a modest limit may fall short on a larger one, because the stressed payment grows with the limit.
Gates That Decide the Outcome
Five gates decide most of these files, and each one is easy to check before you apply.
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). If the old line itself was opened recently, the lender’s review decides whether that earlier loan resets the clock. Check this first. It is a more affordable problem to find early.
Credit and history. The minimum score is 720 on a second lien and 700 on a first lien, using the lender’s own report. There can be no 30-day mortgage late in the last 12 months. Forty-eight months must have passed since a bankruptcy, foreclosure, short sale or deed-in-lieu.
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.
Property type. Single-family, PUD, townhome, two-to-four-unit and condominium properties, warrantable or not, are eligible property types, and the leverage tiers above govern each one. Rural-designated property, condotels, row homes and leaseholds do not fit. Neither does a property listed for sale in the prior 2 months or one with a solar lien.
Borrower and exposure. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are eligible. Foreign nationals and ITIN borrowers are not. Exposure is capped at 5 loans or $2,500,000 per borrower within the program, so this is not a route for unlimited scaling. No reserves are required.
Vesting in an LLC is allowed on an investment property, subject to 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.
Lendmire’s piece HELOC Requirements for Refinancing a Balance Into a New HELOC goes deeper on the paperwork side.
What Happens to the Draw Clock?
A new line starts a new clock. The program gives 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.
Moving a balance into a new line therefore buys time. It also keeps the debt exposed to a variable rate. Payments change once a draw period ends, as Experian’s explainer on draw periods lays out. That shift is the main reason to plan an exit before you refinance. The CFPB’s HELOC booklet also reminds borrowers that any line secured by property puts that property at risk if the debt goes unpaid.
The rate and pricing terms come with the lender’s disclosures, not from this article.
What About a Frozen or Ending Line?
A frozen line is a common reason investors look for a new one. When the old lender stops allowing draws, the balance still has to be managed. Waiting is one option and refinancing is another.
The key point is that a freeze on the old line does not by itself block a new application. The new line is judged on the rent, the credit report, the valuation and seasoning. Still, a line in its final repayment stage is a good time to start, because payments only rise from there.
Business-Purpose Treatment, Briefly
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. Whether a credit counts as business-purpose turns on its primary purpose and the facts, as CFPB’s Regulation Z § 1026.3 frames it. That is one more reason this product is never offered on the owner’s own home or a second home.
When Not to Refinance Into a New Line
Skip the swap in these cases.
- The old line is on your primary residence. This program cannot replace it.
- The rental was bought or refinanced inside the last 6 months.
- You only need a small amount. The 80% draw rule and the $50,000 minimum favor larger needs.
- Rent is thin against the whole limit. A lower limit may clear 1.10x where a larger one does not.
- You would rather lock a fixed payment. A DSCR cash-out refinance that folds in the mortgage and the line may suit you better, though it replaces your first mortgage.
- You are close to the per-borrower cap of 5 loans or $2,500,000.
- The balance simply needs to be paid down. The swap would only postpone the problem, whether the pressure comes from a freeze or an ending draw period.
An investor with a paid-off rental and a strong lease may find a first lien the cleanest option. An investor with a low-rate first mortgage and a second lien coming due usually leans toward a second lien instead. The first mortgage then stays in place.
Common Mistakes
- Sizing the limit by the old balance and forgetting the 80% draw rule.
- Assuming the 1.10x test applies only to the drawn amount.
- Treating a first-lien ceiling as if it applied to a second lien.
- Ignoring that title holders who are not borrowers must still sign.
- Counting on an appraisal waiver, which is not accepted.
- Reading a rental bought months ago as clear of the seasoning rule.
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.
Frequently Asked Questions
Does a refinance close the old line?
Yes, the old line is paid off and closed at closing, and its lien is released. The new line then carries the balance. You are replacing one revolving debt with another, so the amount owed is unchanged unless you draw extra cash.
Can I keep my first mortgage and only replace the line?
Often, yes, through a standalone second lien. The new line sits behind the first mortgage you keep, and combined loan-to-value up to 70% applies at a 720 credit score or better, subject to underwriting. The old second lien must be paid off so the new one is never third.
Can an LLC-held rental qualify?
Vesting in the owner’s LLC is allowed on an investment property, depending on program guidelines. The members sign as guarantors. A title holder who is not a borrower signs an acknowledgment and the security instrument.
Which states offer this?
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.
What if my credit score is below 720?
A second lien needs 720 or better, so a lower score has no second-lien option. A first lien on a rental with no mortgage starts at 700, with leverage stepping down at lower tiers. Lendmire can compare options based on the property, the rent, the equity available and your credit profile.
