The Quick Read: To compare a cash-out refinance against your existing HELOC, line up the total payoff of every lien, the full cost of the new loan, and the rent coverage the new payment leaves you, then test them against the new lender’s leverage cap. Do those checks before you look at any single headline number.
- Get a written payoff for the first mortgage and the HELOC. Neither equals your statement balance.
- Add up all costs, including any prepayment charge on the old loan, because they come out of your proceeds.
- Check that both liens fit under the new loan’s leverage cap. Across most of our network, cash-out on a standard rental tops out around 75% LTV.
- Confirm the rent still covers the new payment. A coverage ratio of 1.00 is where many select programs start.
- Ask how the lender labels the HELOC payoff, because that label can change pricing and eligibility. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Key Terms Defined
A few terms come up in every one of these files. Here they are once, in plain words.
HELOC (home equity line of credit): A revolving credit line secured by a property. You borrow what you need, and you pay interest only on what you have drawn.
Draw period: The stretch when you can still borrow from the line. Payments are often interest-only during this time.
Repayment period: The stretch after the draw period ends. You can no longer borrow, and the balance amortizes, meaning each payment includes principal.
Cash-out refinance: A new first mortgage that pays off the old one and puts the extra equity in your hands. Lenders treat it differently from a refinance that only replaces what you owe.
Rate-and-term refinance: A refinance that only replaces the existing debt, with no meaningful cash back.
LTV and CLTV: Loan-to-value is the loan divided by the property’s value. Combined loan-to-value adds every lien on the property together.
Lien position: Your place in line to be repaid if the property is sold. A new first-lien lender wants the first spot.
Payoff letter: A written statement of what it takes to retire a loan on a specific date. It includes accrued interest and fees.
Per diem: The daily interest added to a payoff when closing slips past the date on the letter.
DSCR (debt service coverage ratio): The property’s monthly rent divided by its full monthly payment of principal, interest, taxes, insurance, and any HOA dues.
Prepayment penalty: A fee for paying a loan off early, usually within a set number of years.
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 Are You Actually Comparing?
You are comparing three paths, not two. Most borrowers frame the choice as “refinance or don’t,” but the useful question is which of three structures leaves you with the best monthly coverage, total cost, and flexibility.
The paths are these:
1. Keep both loans as they are. The first mortgage and the HELOC stay in place.
2. Combine them. One cash-out refinance pays off the first mortgage and the HELOC and leaves a single lien.
3. Refinance only the HELOC. You replace the line with a different structure, such as a new standalone line, and leave the first mortgage alone.
| Factor | Keep both | Combine in one cash-out | Replace only the HELOC |
|---|---|---|---|
| Number of liens | Two | One | Two |
| First mortgage | Untouched | Replaced | Untouched |
| Payment behavior | Line may float | Set by new loan | Depends on new line |
| Closing costs | None new | Highest | Moderate |
| Seasoning needed | None | Often about 6 months | Varies |
| Main risk | Payment jump | Losing a cheap first loan | Floating pricing persists |
Why do investors consider combining? The usual driver is the end of the draw period. When interest-only payments give way to a fully amortizing schedule, the payment on a rental can rise while the rent stays flat. Others simply want one lien and one payment instead of two.
Why do some skip it? A cash-out refinance replaces the entire first mortgage, not just the HELOC. If your first mortgage is cheap, you give that up to fix a line that may be a small part of your debt. When the first mortgage is expensive or maturing anyway, combining costs you less in lost benefit.
How Do You Compare the Offers, Step by Step?
Work the same sequence for every offer so the numbers stay comparable. Here is the order we use when structuring these files.
Step 1: Gather payoffs, not balances. Request payoff letters for both liens. Each one carries a good-through date, and daily interest means a later closing raises the figure.
Step 2: Price your current setup. Add the first mortgage payment and the HELOC payment together. If the line is still interest-only, remember that this total will change when repayment begins.
Step 3: Get matching quotes. Ask each lender for the same loan type, the same term structure, and the same leverage. Quotes built on different assumptions cannot be compared.
Step 4: Itemize the costs. DSCR loans are business-purpose loans, so they sit outside the standardized consumer disclosure forms. Ask each lender for an itemized fee sheet in the same layout, and compare these lines:
- Lender and broker charges
- Appraisal, title, and escrow fees
- Payoff lines for each lien, including per diem interest
- Any prepayment charge on the old first mortgage
- Any early-closure fee on the HELOC
- Reserves the lender requires you to keep
Step 5: Run the leverage test. Add the first mortgage payoff and the HELOC payoff together, then add costs. Divide by the appraised value. That combined figure must fit under the new lender’s cap.
Step 6: Run the coverage test. Divide the rent by the new full payment. A single larger loan raises the payment the rent has to cover, so the ratio moves. One thing to keep straight: clearing 1.00 does not mean the property cash flows. Coverage compares rent to the payment only, and repairs, vacancy, management, utilities, and capital expenses sit outside it.
Step 7: Find the break-even. Divide total new costs by the monthly savings from the combined structure. If costs equal ten months of savings, you recover them in ten months. If you may sell or refinance again before then, the combined loan loses.
Step 8: Check the term. A new 30-year fixed loan restarts your amortization clock. Extended terms and interest-only periods are available through select lenders in the network, and each changes both the payment and the total interest.
A Worked Comparison in Ratios
Say a rental’s first mortgage and HELOC payoffs together equal 60% of the appraised value. Add closing costs and the figure moves toward 63%. That fits under a 75% cash-out cap on a standard rental with room to spare. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Now say the combined payoffs already equal 74%. After costs, the file is over the cap, and you would bring cash to closing or drop the idea. The same logic applies to short-term-rental collateral, where cash-out sits at 70% instead of the 75% available on standard rentals.
On coverage, assume the rent covers the old combined payments at about 1.30x. After combining, the new payment is larger because the line’s balance is now fully amortizing, and coverage lands near 1.15x. That still clears 1.00, but you gave up cushion. The question then is whether the lower risk of a floating line is worth that.
HELOC Payoff Mechanics: Closing the Line, Not Just Zeroing It
The payoff is where otherwise clean files go wrong. A new first-lien lender wants first position, so the HELOC has to be paid off, or its holder has to agree in writing to stay second. That agreement is called subordination. It is a request, not a right, and the junior lender can say no. A refusal usually leaves payoff as the only path.
Here is the sequence that protects you.
1. Request the payoff in writing. Federal Regulation Z payoff-statement rule requires a servicer to give an accurate payoff statement within a reasonable time, and no more than seven business days after a written request. The rule is written around credit secured by a consumer’s dwelling. If your line sits on a rental, it may not apply, so request the payoff in writing anyway. The title company or new lender can send the request for you.
2. Freeze the line. Ask the HELOC lender to stop further draws when you request the payoff, so the number stops moving. A title-industry practice note also advises signing a written request to close and satisfy the account.
3. Close the line. Paying a HELOC to zero does not necessarily close it. A title underwriter’s claims case study describes a payoff statement with check boxes for payoff only versus payoff, terminate, and satisfy. When neither was checked, the account stayed open and no release was ever recorded.
4. Confirm the release. Get written confirmation of closure and a recorded lien release after closing.
5. Read your line agreement. Some HELOC agreements charge a fee, or claw back waived costs, when a line closes early.
Where the General Rule Breaks
Every comparison above assumes a clean situation. These are the cases that change the answer.
The HELOC sits on a different property. A line secured by your primary home is not a lien on the rental. Refinancing the rental will not clear it. You would pay that line down or handle it by refinancing the home.
The lender labels the payoff as cash-out. Whether paying off a HELOC counts as rate-and-term or cash-out is the lender’s call, and the label changes leverage and pricing. Draws taken for unrelated purposes are the likeliest trigger for cash-out treatment. Lendmire’s piece Does Paying Off a HELOC in a Refinance Make It a Cash-Out Refinance? goes deeper on this. Do not assume the way conventional lenders treat it carries over to a DSCR file. Ask how the lender will classify it before you pay for an appraisal.
A never-used line. A zero-balance line is still a recorded lien. It still needs closure or subordination.
Recent draws. Money drawn shortly before applying invites questions about where it went and how it was used. Expect the lender to ask.
Seasoning. About six months of ownership is the common expectation for a cash-out refinance on our network. A property bought recently may need to wait.
Title and vesting. HELOC programs generally require title in your name or an individual’s revocable living trust. DSCR loans can often close in an LLC, subject to lender program eligibility. If your rental is already in an LLC, a HELOC may not be an option at all. A DSCR cash-out would be.
Property type. DSCR programs in the network do not offer manufactured homes (single- and double-wide), log homes, or barndominiums. If your collateral is one of those, the combined-refinance path does not exist.
Coverage below 1.00. If the larger payment drops you under 1.00, programs below 1.00 are available through select lenders in the network, with leverage and terms adjusted. Expect lower leverage and different terms than a standard file.
Replacing the line instead. If you would rather keep your first mortgage, a new standalone line is an alternative. On investment property across our network, equity lines carry a ceiling of 70% CLTV, require a score of at least 700, and cap at $500,000 in total. They use a 5-year interest-only draw and a 25-year repayment, at least 75% of the line is drawn at closing, and pricing floats and never converts to fixed. These lines are available in 16 full-service states. Primary-residence and second-home lines follow different tiers. Everything is subject to lender guidelines and full file review.
What the Investor Decision Looks Like
You are choosing between three costs: the cost of staying put, the cost of switching, and the cost of being wrong about timing.
Staying put costs the most when the draw period is ending. The CFPB’s explanation of home equity lines notes that payments are often significantly higher once repayment begins, and that variable pricing means payments can change from month to month. If your rent is flat, that squeeze lands directly on your coverage.
Switching costs the most when your first mortgage is cheap. You would trade a low-cost loan to solve a problem the line created. In that case, replacing only the HELOC, or paying it down, usually beats combining.
Timing matters on both sides. A combined refinance usually carries a new prepayment penalty schedule that restarts at closing. The old loan’s own fee is owed at payoff. If you may sell within a few years, add the penalty to your break-even.
Most files we see are decided by two numbers: the combined leverage after costs, and the coverage ratio after combining. If both clear, the choice becomes about preference. Reserves are the other piece. They vary by lender, leverage, loan size, and transaction type, and commonly sit around six months of PITIA (principal, interest, taxes, insurance, and association dues). Conservative rate-and-term files at modest leverage under $1,500,000 can see them waived, and larger loans typically step up to about nine months.
Credit also shapes the outcome. Most programs want a score around 660, a 620 floor exists in parts of the network, and 700 or better opens the strongest leverage tiers. Standard loan sizes reach up to $3,000,000 on standard programs, with smaller balances available through select lenders, and loans above $2,500,000 generally stay with 30-year fixed structures.
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.
For the full picture of how these programs fit together, see the complete DSCR loans guide. If you are still deciding between a line and a refinance on a rental, Lendmire also covers how a HELOC compares with a cash-out refinance on a rental property.
Frequently Asked Questions
Can a cash-out refinance on my rental pay off a HELOC?
Only if the HELOC is secured by that rental. The new loan pays off the first mortgage, the HELOC, and closing costs, and you receive whatever remains. A line secured by your primary home is a separate lien, and refinancing the rental does not touch it.
Will the lender treat the payoff as cash-out?
It depends on the lender. A HELOC paid off at closing may be classified as cash-out, particularly if it was drawn for purposes unrelated to the property. Conventional lenders often use stricter definitions of rate-and-term, but DSCR lenders may not follow them. Ask for the classification in writing before you order an appraisal.
Does paying my HELOC to zero close it?
No. The line and the lien remain until they are formally closed and released. Sign the closure request, confirm the payoff lender received it, and verify that a release is recorded after closing.
What if the HELOC lender refuses to subordinate?
Plan for payoff. Subordination is a consent request, and the junior lender has no duty to grant it. The workarounds are paying the line off at closing, paying it down first, or closing it.
Does clearing 1.00 coverage mean the rental is cash flow positive?
No. The ratio compares rent to the full monthly payment and nothing else. Repairs, vacancy, management, utilities, and capital expenses are outside it, so budget for them separately.
