The Quick Read: Big banks rarely write this product. A DSCR HELOC that pays off an old line on a rental sits in the non-QM wholesale channel, where a broker places the file with a lender that qualifies the line on the rent, not the owner’s income. It works when the old line is secured by the rental itself and the rent covers the new qualifying payment, subject to lender guidelines.
- The old HELOC must be secured by the rental. A line on your own home is a separate file.
- Qualification runs on property rent, with a minimum 1.10x coverage ratio, not on personal income.
- Through select programs, a second lien reaches 70% CLTV at a 720 score or better, on lines up to $500,000.
- A first lien on a rental with no mortgage reaches 75% LTV at a 740 score or better.
- The program is offered in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Why Banks Rarely Offer This
Few banks write HELOCs on rentals at all. NerdWallet reports that investment-property HELOCs are not offered by every lender and carry strict requirements.
Those are bank rules for bank products. They test the borrower first: credit, debt-to-income, and equity. A DSCR line flips the order and tests the property first. Rent is divided by a qualifying payment, and the owner’s tax returns, W-2s and pay stubs stay out of the calculation.
That shift is why the product lives outside most bank branches. Lendmire is a mortgage broker, not a lender. It works with a nationwide network of wholesale DSCR HELOC lenders and matches the scenario to the program. Which lender fits depends on the property type, credit profile, leverage need, and how the old line is structured. No single bank name answers the question, and any list that claims otherwise is skipping the file details that decide it.
Key Terms Defined
DSCR: the debt service coverage ratio, which is gross monthly rent divided by the qualifying payment.
HELOC: a revolving line of credit secured by property. Per the CFPB’s HELOC booklet, you borrow, repay and borrow again during a draw period, then move into a repayment period.
CLTV: combined loan-to-value, meaning the first mortgage balance plus the new line, divided by the property’s value.
Subordination: a written agreement in which a lien holder agrees to stay in second position behind a new first mortgage.
Seasoning: the minimum time since a purchase or refinance before a rental can be used for a new line.
What “Refinance an Existing HELOC” Can Mean
The phrase covers four different moves, and each works differently.
1. Pay off the old line with a new DSCR line. The new line closes, title pays off the old lender, and the old line is closed.
2. Roll everything into a DSCR cash-out refinance. One new first mortgage replaces the first mortgage and the HELOC together.
3. Refinance the first mortgage and keep the old HELOC. This needs the HELOC holder’s written subordination.
4. Move the balance to another junior lender. A different lender writes a new junior lien on the rental and pays off the old line, so the old line is closed. Few lenders write rental lines, so the choice of lender is narrow.
A DSCR HELOC fits the first route. It is a standalone second lien behind a first mortgage you keep, or a standalone first lien on a rental with no mortgage. It is never a third lien and never closes together with a purchase.
| Situation | Likely route |
|---|---|
| Old HELOC on the rental, first mortgage you want to keep | New DSCR line as a second lien pays off the old line |
| Old HELOC on a paid-off rental | New DSCR line as a first lien |
| Old HELOC on your own home | Separate file; a rental line does not release it |
| First mortgage also needs replacing | Cash-out refinance, often the cleaner path |
How Underwriting Treats the Payoff, Step by Step
Step 1: Identify which property secures the old line. Many bank lines sit on the owner’s primary home. A DSCR line on a rental pays off only liens recorded against that rental.
Step 2: Request the payoff letter. HELOC balances move with draws and daily interest, so the payoff is a moving figure. The old lender issues a letter, and title uses it at closing. Ask the old lender to close the account so the line cannot be redrawn.
Step 3: Test the rent. The minimum is 1.10x, calculated as gross monthly rent divided by a qualifying payment. That payment is a fully amortizing payment on the entire credit limit at a stressed rate, covering principal and interest only. Taxes and insurance are not part of it. 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, and a two-to-four-unit property may have at most one vacant unit.
On a second lien, confirm on the file how the lender treats the first-mortgage payment. The lender’s own coverage calculation governs.
Step 4: Check combined leverage. On a second lien, the first mortgage balance plus the new line must fit within 70% CLTV at a 720 score or better, on lines up to $500,000. Below 720 there is no second-lien option. Because the whole line counts, a large limit uses leverage even if you draw less later.
Step 5: Value the property. Lines up to $400,000 use an automated valuation with a property inspection report, or a full interior appraisal. Larger lines take a full interior appraisal. Appraisal waivers are not accepted.
Step 6: Clear 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).
Step 7: Close and record. Title pays the old line, the old lender releases its lien, and the new line records. Subject to underwriting, the borrower sees the lender’s HELOC disclosures before closing.
Is the Payoff Cash-Out?
Often, yes. Classification is program-specific. A BiggerPockets thread includes one commenter’s view that paying off a HELOC with a DSCR refinance can still count as rate-and-term when under $2,000 comes back at closing. That is an agency-style convention from one investor, not a rule across DSCR programs. Many non-QM programs treat a HELOC that did not fund the purchase as cash-out even when no money returns to the borrower.
The practical point: do not assume a payoff is a plain rate-and-term refinance. Ask how the lender classifies it before leverage limits are calculated.
The Structure and Variations
Second lien behind a kept first mortgage. This suits an owner with a first mortgage worth keeping. The line sits behind it at up to 70% CLTV, at a 720 score or better, on lines of $50,000 to $500,000.
First lien on a rental with no mortgage. At a 740 score or better, leverage reaches 75% LTV on lines up to $500,000. From 700 to 739 it is 70% LTV. Lines above $500,000, up to $1,000,000, carry a 65% LTV ceiling at 720 or better. The first-lien floor is a 700 score. A first lien exists only on a rental with no mortgage. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Draw and repayment terms. The draw period is 5 years of interest-only payments on the drawn balance, then a 25-year fully amortizing repayment period, with a 30-year maturity. The rate is variable. At least 80% of the line is drawn at closing, never under $50,000, and later draws are at least $5,000 each.
LLC title. The line can be vested in the owner’s LLC on investment property, subject to lender program eligibility. The members sign as guarantors. Bank investment HELOCs often prefer individual or trust title, as one lender commenter notes in the BiggerPockets thread above, so LLC vesting is one reason investors leave the bank channel.
Where the General Rule Breaks
The old line is on your home. A rental line cannot pay it off. This program is never offered on an owner-occupied home or second home, so that line needs its own solution.
You want to refinance the first mortgage and keep the HELOC. The new first mortgage records after the old HELOC, so the HELOC would move up to first position unless its holder signs a subordination agreement. As the Wikipedia entry on subordination agreements explains, if the second-mortgage holder will not subordinate, the new lender will not refinance the first. The fallback options are to pay the HELOC off at closing or replace both liens with one larger first loan.
You bought or refinanced recently. The two six-month clocks above apply, and they can rule out an otherwise strong file.
The rent is the problem. The qualifying payment is stressed and sized on the full limit. A modest draw does not shrink it. Coverage that looks fine on today’s balance can fall short at 1.10x, and the BiggerPockets thread points out that any remaining HELOC balance you carry belongs in the analysis too.
The property type is out. Rural-designated property, row homes, condotels, leaseholds, land trusts, age-restricted communities, hobby farms, modular and log homes, mixed-use property, a property listed for sale in the prior 2 months, and a property with a solar lien sit outside the program. A declining-market flag lowers the ceiling 5 points, and Philadelphia lines carry a ceiling 10 points lower.
The borrower is out. Foreign nationals and ITIN borrowers are not eligible. U.S. citizens, permanent residents and non-permanent residents with a Social Security number are.
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.
Worked Example: Stacking the Liens
Take a rental valued at $500,000 with a first mortgage balance of $250,000, a 740 score, and rent that clears the 1.10x test. At 70% CLTV, combined debt tops out near $350,000. Subtract the first mortgage and the new line would be capped near $100,000, subject to underwriting.
If the old HELOC currently holds a balance on this same rental, the new line must pay it off, and the old line is closed. Illustrative arithmetic only; the lender’s own calculation governs. The practical test is whether the new line covers the payoff and still clears coverage on the full limit.
When This Is the Wrong Product
Skip the DSCR HELOC when:
- The first mortgage also needs replacing. A cash-out refinance handles both liens in one file.
- The score is 700 to 719 and you want to keep a first mortgage. A second lien starts at 720.
- The old line is on a property type the program excludes.
- You need less than $50,000, since lines start there.
- You live in Tennessee or another state outside the 15 where the program is offered.
An expiring draw period is one reason to compare structures. When the draw period ends, payments move to the repayment period, and the CFPB booklet describes that change. Owners who plan ahead have more room to compare structures than owners who wait for the first larger payment.
What to Prepare
- A current payoff letter for the old line and a list of every lien on the rental.
- The signed lease and recent rent receipts.
- Vesting documents if the LLC holds title, plus guarantor details for each member.
- A current mortgage statement for the first mortgage you intend to keep.
- Proof of identity and Social Security number for each borrower.
No traditional personal-income documentation, W-2s, pay stubs or debt-to-income ratio are needed, since the line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. The program requires no reserves. Exposure is capped at 5 loans or $2,500,000 per borrower with the program.

Frequently Asked Questions
Do any big banks offer a DSCR HELOC on a rental?
Rarely. Big banks underwrite rental lines on the borrower’s income and credit, and many do not write them at all. DSCR lines come through wholesale non-QM lenders, which a broker such as Lendmire shops on the borrower’s behalf. The lender that fits depends on the property, credit and leverage.
Can one new line pay off an old HELOC that sits on my home?
No. The program is for non-owner-occupied one-to-four-unit rentals and is never offered on an owner-occupied home or second home. A line secured by your residence stays a separate loan, and its payoff needs a different product.
How long after buying or refinancing can I apply?
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). Both are measured at the new note date.
What if my old lender will not subordinate?
Then the usual choices are to pay the HELOC off at closing or to replace both liens with a single larger first loan. Without subordination, a new first mortgage cannot close ahead of an existing HELOC.
Does the rent have to cover my current HELOC payment?
The test uses a qualifying payment on the entire new limit, not your current payment. Lenders differ on how a kept first mortgage enters that calculation, so confirm on the file how the lender treats it.
