The Quick Read: A new first-lien loan sized to pay off the old mortgage and the credit line at closing leaves one lien and one amortizing payment, and that combined payment is usually lower only against the old two-payment setup, not against the first mortgage alone.
- The HELOC sits behind your first mortgage, so a new first-lien lender needs it paid off or subordinated before it will close.
- Across Lendmire’s wholesale network, a cash-out refinance tops out around 75% LTV on a standard rental, and about 6 months of seasoning is the common expectation.
- Rolling the balance in makes the loan bigger, so the DSCR (rent divided by the full monthly obligation) drops even as the combined payment may fall.
- The strongest files clear two tests: enough equity and enough rental coverage. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Investors usually reach this question when a variable-priced line is about to leave its interest-only period. This guide walks the mechanics in order, then shows where the general rule breaks.
How large a line the equity supports.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
What Does It Mean to Fold a HELOC Into a Refinance?
Folding in means one new first-lien loan pays off your existing first mortgage and your HELOC together, and the HELOC account is closed. You end with one lien, one payment, and a fixed amortization schedule instead of a first mortgage plus a floating line.
The reason is lien position. A HELOC is a junior lien. When the first mortgage is paid off, its lien is released, and the HELOC would move up to first position. No new first-lien lender will close behind that. Bills.com’s consumer explainer on subordinating a HELOC for a refinance lays out the two exits: the HELOC lender signs a subordination agreement and stays in second position, or the HELOC is paid off. The HELOC lender has no obligation to subordinate. That leaves three real options: subordinate, pay it off with cash, or pay it off through the new loan.
Folding it in is the third option. It is also the one that changes your DSCR file the most.
How Underwriting Treats the HELOC Payoff, Step by Step
Underwriting treats the payoff as part of the total loan amount, and it tests that amount against appraised value and rent. Each step below shows where the file can stall.
1. Pull the HELOC’s current terms. Get the balance, credit limit, draw or repayment status, and any early-closure fee. Ask the HELOC lender for a payoff statement.
2. Check the old documents for prepayment terms. A prepayment penalty on the loan being replaced is triggered by the refinance. A short-term investor loan with a penalty period can make folding in expensive. Also check whether the HELOC has its own early-closure charge.
3. Order title. A title search shows every recorded lien, including a HELOC the owner forgot about or one with a zero balance that was never formally closed. A line at zero balance is still a recorded lien until it is released. Clearing title on those is the most common preventable delay.
4. Appraise and size the loan. Total payoff means the first mortgage balance, the HELOC balance, accrued interest, and closing costs. That figure over the appraised value sets the LTV. Once the HELOC is retired, LTV and combined LTV are the same number.
5. Run the DSCR test. Monthly rent is divided by the full PITIA: principal, interest, taxes, insurance, and any association dues. The new, larger obligation is what gets tested. More loan means more PITIA, which means a lower ratio.
6. Pay off and close the line. The title company wires the payoffs and collects the lien releases. The borrower should ask the HELOC lender to close the account, not just freeze it, so the line cannot be redrawn.
What decides the outcome. Appraised value against total payoff, rent against the new PITIA, the credit profile, how and when the HELOC was drawn, vesting and title, and the prepayment terms on the loan being replaced. Everything else is detail.
Is a HELOC Payoff Treated as Cash-Out?
Usually, yes. Lenders commonly classify a payoff of a junior lien that was not used to buy the property as a cash-out refinance, and cash-out tiers apply. Agency conventional lending draws the same line; Fannie Mae’s definition of a limited cash-out refinance turns on how the subordinate lien was used. DSCR loans are not agency products, though, and each program in the network sets its own rules. Do not import agency thresholds into a DSCR file.
What this means in practice:
- A cash-out refinance tops out around 75% LTV across most of the network. A file that would have been fine as a straight rate-and-term refinance can run into that ceiling once a HELOC balance is added.
- Short-term rental collateral is capped lower. Cash-out on an STR runs around 70% LTV, and expect a 640+ score and about 12 months of hosting history.
- About 6 months of seasoning is the common expectation on a cash-out. Seasoning rules differ by lender, and a recent HELOC draw can draw extra questions.
- If the HELOC draws bought the subject property, some lenders may treat the file differently than if the draws funded something unrelated. That is lender-specific. Do not assume either way.
Will It Actually Lower Your Payment?
It lowers the combined payment in many cases, but it rarely lowers the payment against the old first mortgage alone. The comparison matters. Picking the wrong baseline is how investors talk themselves into a bad refinance.
Three baselines apply:
- Old first plus HELOC. This is the real comparison. Folding in replaces two obligations with one, and the combined obligation often falls, particularly if the HELOC is interest-only or floating.
- Old first alone. The new loan is larger, so the obligation on it is usually higher than the old first by itself.
- HELOC after its draw period ends. The CFPB’s HELOC explainer describes an open-end line with a draw period followed by a repayment period in which you can no longer borrow. Payments on a line that was interest-only during the draw period often rise at that switch, and pricing on most lines floats throughout. Folding the balance into an amortizing first-lien loan removes both the reset and the floating exposure.
What moves the new payment: the combined balance, the term, financed closing costs, and the new amortization clock. Extending the term can shrink the monthly number while raising total interest paid over the life of the loan. A lower payment bought with a longer clock is a trade, not a saving.
The term menu is wider on DSCR files than most investors expect. The spine is the 30-year fixed. Extended terms (40-year) and interest-only periods are available through select lenders in the network, and ARM structures exist for investors who want them. Loans above $2,500,000 generally hold to 30-year fixed structures.
Run the Coverage Math Before You Commit
The coverage ratio falls when the HELOC is folded in, and that is the number to check first. Here is a modeled example using percentages and ratios, not market data.
Run the numbers on a rental valued at 100 units, with a first mortgage at 50% of value and a HELOC at 15% of value. Total payoff, before closing costs, is 65% of value. That sits inside a cash-out ceiling around 75% on a standard rental, with some room for costs. Say rent covers the old first mortgage alone at roughly 1.5x. Add the HELOC balance into the new loan and the same rent might cover the larger obligation at roughly 1.2x. The file still clears 1.00. It just has less cushion.
Now push it. Same property, but the first mortgage is at 60% and the HELOC at 18%. Payoff is 78% before costs. That is over the cash-out ceiling, so folding everything in does not work as structured. The options are to pay the HELOC down with cash, subordinate it, or wait for appraised value to rise.
Two points on the ratio itself:
- 1.00 is where many select programs start. It is a floor for specific programs, not a universal standard. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Clearing 1.00 is not the same as positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation.
An investor who folds a HELOC in to fix a coverage problem should confirm the new ratio, not the new payment, because coverage is what the lender tests.
Fold It In, Subordinate It, or Pay It Off?
The right choice depends on what the existing first mortgage looks like and how large the HELOC is. This table compares the three exits.
| Option | What happens | Best when |
|---|---|---|
| Fold it in | New first pays off both loans | HELOC is large, floating, or near repayment |
| Subordinate it | HELOC stays behind the new first | First mortgage is cheap and HELOC lender agrees |
| Pay it off with cash | HELOC retired separately | Balance is small and cash is idle |
Subordination can beat replacing both loans when the existing first mortgage is attractive. The catch is that the HELOC lender can refuse, and fees and timing apply. Combined leverage limits apply too, and the new lender reviews the junior line’s terms.
Paying a small balance down with cash is often the cleanest route. It keeps the loan amount down, protects the coverage ratio, and avoids financing closing costs on debt that was easy to retire.
Where the General Rule Breaks
Several situations break the simple version of this story. Knowing them in advance is what keeps a file clean.
The HELOC is on a different property. Investors often use a line on their primary residence to fund a rental down payment. Folding only works when the HELOC is secured by the property being refinanced. Paying off a primary-residence line out of rental cash-out is a separate matter: the rental refinance is cash-out used to pay off a debt, and leverage is tested on the rental alone. For that decision, Lendmire’s piece on the tradeoff in Smaller HELOC vs Larger Cash-Out Refinance for a Rental Down Payment covers it.
Appraised value still depends on comparable sales and underwriter review.
LLC vesting. HELOC programs generally require title in an individual’s name or a revocable trust. Lendmire’s own investment-property line, for example, runs up to 70% CLTV and $500,000 and cannot be held in an LLC, corporation, partnership, or irrevocable trust. DSCR refinances commonly allow an LLC, subject to lender program eligibility. A property already deeded to an LLC that carries a personal-name HELOC may need a vesting fix before the refinance, and title review should catch that early.
A recent draw. Lenders may look at how recently the line was used. A large draw shortly before the application can raise seasoning questions. Policies differ by lender.
A frozen or reduced line. The CFPB’s HELOC page notes that lenders can suspend further draws if the home’s value drops or the borrower’s finances change. A line you counted on for liquidity can disappear. Cash from a refinance sits in the bank and may count toward reserves, subject to lender guidelines.
Prepayment penalty. If the loan being paid off carries one, the refinance triggers it. Add that to the break-even math.
Ineligible property types. DSCR programs in the network do not offer manufactured homes (single- and double-wide), log homes, or barndominiums. A HELOC on one of those does not become a DSCR refinance.
What Else the Lender Will Look At
A HELOC is reviewed on the borrower: credit, income, and debt-to-income. A DSCR refinance qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. For high-DTI or self-employed investors, that shift is often the real reason to fold the line into a refinance. Credit still matters. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers.
Other items that shape the file:
- Loan size. Loan amounts of up to $3,000,000 are available on standard programs, and smaller balances are available through select lenders.
- Reserves. They vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common on a cash-out. Conservative rate-term files at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months. Hold reserve documentation ready, since it is a frequent gap.
- Down payment versus equity. On a refinance, equity plays the role of down payment. More equity lowers the loan amount and lifts the ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.
Program details change, and every file is underwritten individually. Treat the figures here as typical ranges, not commitments to lend. Lendmire’s complete DSCR loans guide covers how the programs fit together.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Costs and Break-Even
Folding in costs money up front, so the monthly savings have to repay it. Closing costs include appraisal, title, recording, and lender fees. You can pay them out of pocket or finance them into the loan, but financing them enlarges the balance and trims coverage.
The break-even test is simple. Divide total costs by monthly savings against the baseline you actually hold, which is the old first plus the HELOC. The answer is how many months you must keep the loan before the refinance pays for itself. If you plan to sell or refinance sooner, folding in loses. Add any prepayment penalty on the old loan to the cost side.
One more check: if the savings come entirely from a longer term, compare total interest as well. A smaller payment is not a smaller cost.

Frequently Asked Questions
Can I fold a HELOC into a refinance on a rental property?
Yes, when the HELOC is secured by the same property you are refinancing. The new first-lien loan pays off the old mortgage and the line at closing, and the HELOC account is closed. Leverage is tested on the total payoff over appraised value, and cash-out tiers commonly apply, around 75% LTV on a standard rental across most of the network.
Will folding in the HELOC lower my payment?
It depends on the baseline. It often lowers the combined old-first-plus-HELOC obligation, especially against a floating or interest-only line. It usually raises the obligation versus the first mortgage alone, since the new loan is larger. Check the new DSCR as well, because the bigger loan lowers coverage.
What if my HELOC is in an LLC-owned property?
HELOC programs generally require individual or revocable-trust title, while DSCR refinances commonly allow an LLC, subject to lender program eligibility. A personal-name HELOC on an LLC-deeded property may need a vesting change first. Title review will show it.
Can I keep my first mortgage and just deal with the HELOC?
Only if the HELOC lender subordinates or you pay the line off separately. If the first mortgage is being replaced, the HELOC cannot simply stay behind a new lender without that agreement. Subordination can make sense when the existing first is attractive, but the HELOC lender can refuse.
Does paying off the HELOC close it?
Not automatically. A zero balance does not release the lien. You should request closure in writing so the line cannot be redrawn, and title should confirm the recorded release.
