The Quick Read: A cash-out refinance that pays off a HELOC replaces your first mortgage and your credit line with one new loan, so the variable or stepped-up HELOC payment disappears, and the new payment is higher or lower depending on the new balance, the new term, and whether you give up a cheaper first mortgage. On a rental, that single payment is also the number your rent has to cover.
- Two payments become one, and a floating payment becomes a fixed-schedule payment.
- The payment is not guaranteed to fall. A bigger first lien and a lost low-rate first mortgage can push it up.
- A longer term lowers the monthly figure but usually raises lifetime interest.
- Paying the line to zero does not close it. The lien must be released.
- On a rental, the combined payment goes into the coverage ratio, so rent has to carry it.
What Actually Happens to Your Two Payments?
Before the refinance, you probably carry two obligations on the property. One is the first mortgage. The other is the home equity line of credit (HELOC), which behaves very differently.
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.
The new loan is sized to do three jobs. It pays off the old first mortgage and pays off the HELOC. It also covers closing costs, plus any extra cash you choose to take. Whatever is left after the payoffs and costs is your net cash.
Once it closes, the HELOC payment is gone because the HELOC is gone. In its place is a single payment on a term loan, built on a set schedule. Our wholesale network’s standard spine is the 30-year fixed. Select lenders also offer 40-year terms, interest-only periods, and adjustable structures for investors who want them.
So the payment changes shape, not just size. A line that floated, paid interest only, or stepped up becomes one steady payment you can plan around. The trade is that you can no longer draw on it. A cash-out refinance is one lump sum with no revolving access afterward.
Key Terms Defined
HELOC: A home equity line of credit, a revolving line secured by a property, usually with a floating payment.
Draw period: The early stretch when you can borrow from the line, often paying interest only.
Repayment period: The later stretch when borrowing stops and the balance must be paid down.
Cash-out refinance: A new first-lien loan that pays off existing debt and can return the extra equity as cash.
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 to that loan.
DSCR: Debt service coverage ratio, meaning monthly rent divided by the property’s full monthly payment.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the full payment the rent is compared against.
Per diem: The daily interest that keeps accruing on a payoff until the day it is actually paid.
Subordination: The HELOC lender agreeing to sit behind the new first loan instead of being paid off.
What Decides Whether the New Payment Goes Up or Down?
Four variables move the number. Look at all four before you decide the payoff is a payment cut.
1. The new loan amount. It equals the first-mortgage payoff, plus the HELOC payoff, plus costs, plus any cash taken out. A larger balance pushes the payment up, all else equal.
2. The new rate and term. Rolling a floating line into a fixed, amortizing loan changes the payment’s structure. Stretching the balance over a longer term lowers the monthly figure. It also resets the payoff clock, so total interest usually rises.
3. What happens to your old first mortgage. A cash-out replaces the first. If your existing first mortgage is cheaper than today’s pricing, you give up that advantage on the whole balance, not just the HELOC portion. This is the blended-cost question that most payoff explainers skip. The HELOC balance effectively gets priced at the new first-mortgage terms, and the old low first gets re-priced with it.
4. Any prepayment charge on the old first. Pull the payoff statement and read it. Some investor loans charge a fee when the balance is paid off through a refinance.
The calculator on this site can give an illustrative estimate of how value, balance, occupancy and credit shape the size of a HELOC line. It is a planning aid, not a quote.
How Does the HELOC Payment Behave Before the Payoff?
The old payment is the baseline you are comparing against, and it is rarely steady. The CFPB HELOC booklet notes that some plans allow interest-only payments during the draw period. It adds that a variable-rate line can change your payment even if you borrow nothing more. Some minimum payments that include principal still do not repay the balance by the end of the term. Repayment may run on a set schedule or end in a balloon payment, where the whole remaining balance is due at once.
Draw periods are often long. Bankrate reports that they typically run up to 10 years, interest only. That means the payment you remember is often the most affordable payment the line will ever have. When the draw ends and principal starts, the payment usually jumps.
Here is how the payoff compares by situation:
- Line still interest only. The new payment often looks higher than what you pay now, because you are adding principal. You are buying predictability, not savings.
- Line already amortizing. The comparison is closer. The new loan may lower the monthly figure through a longer term.
- Balloon line. A payoff avoids a lump-sum due date, so the comparison is less about the monthly figure.
- Small line behind a low first mortgage. Replacing the first can cost more than the line ever did. Keeping the first and managing the line may beat a payoff.
What Does the Rent Have to Cover After the Payoff?
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. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It does not run on your personal debt-to-income ratio.
That changes how the payoff looks to the lender. While the HELOC sat outside the property’s financing, its payment never touched the ratio, though it still came out of your pocket every month. After the payoff, it is folded into the single qualifying payment. A larger combined balance raises the payment the rent must carry.
Across our network, a few program realities shape this:
- On a standard rental, cash-out generally tops out around 75% LTV. On short-term-rental collateral, the cash-out ceiling is 70%.
- About 6 months of seasoning, meaning time on title before a refinance, is the common expectation.
- A coverage ratio of 1.00 is where select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit scores of 660 and up suit most programs. A 620 floor exists in parts of the network, and 700 and up unlocks the strongest tiers.
- Standard loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders). Reserves vary by lender, leverage, and loan size, commonly around 6 months of PITIA.
Clearing 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it. For the floating side of the old line, see Lendmire’s explanation of how a cash-out refinance changes the payment on a variable HELOC. Lendmire’s complete DSCR loans guide covers the full qualification picture.
A Modeled Example in Ratios
Treat these as modeled assumptions, not market data. Say a rental is worth 100 units of value. The first mortgage is 50% of that, and the HELOC is another 15%. The combined balance is 65% CLTV.
A cash-out refinance sized to retire both, plus costs, lands the new loan a little above 65% LTV. That sits comfortably under the roughly 75% cash-out ceiling for a standard rental. Now suppose the rent covered the old first mortgage alone at about 1.5x. The new, larger loan might bring coverage down to around 1.2x. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
That still clears the 1.00 level where select programs start. But the cushion is thinner, and it shrinks further if the term is shorter or the loan is bigger. If coverage fell below 1.00, a select-lender path exists, with leverage and terms adjusted. It is a different path from the 1.00 programs, and the file would be reviewed accordingly.
What Happens at Closing?
The payoff is a paper process, and the details protect you.
1. Title surfaces the line. A recorded HELOC is a lien. A new first-lien loan needs it paid off or subordinated.
2. You request a written payoff and freeze the line. Under CFPB Regulation Z §1026.36, a servicer must provide an accurate payoff statement within a reasonable time, and no later than seven business days after a written request. A person acting for the borrower, such as a refinancing creditor, can make the request. Because a HELOC is revolving, an unfrozen line can keep growing, which can leave the payoff letter out of date and too low.
3. The payoff is not the statement balance. It includes interest through closing plus fees. Interest accrues daily, so a slipped closing date raises the number.
4. Funds go to the line’s lender at closing. The final settlement statement should show the first lien paid off, the HELOC payoff with a closure instruction, and the new loan recorded in first position.
5. Release the lien. A zero balance does not remove the lien. Send a written closure request and confirm the release is recorded. Check the line’s agreement for early-closure fees, then keep the closure letter and check the county record afterward.
Where Does the General Rule Break?
Subordination keeps two payments. If the HELOC stays open behind a new first, its lender decides and has no duty to agree. Subordination changes lien priority only. The line’s own terms and payment stay, and its combined-loan test counts the full credit limit, not just the drawn amount.
Labeling. Some conventional files treat a second-lien payoff as a rate-and-term refinance in narrow cases, such as a HELOC used entirely to buy the home. On a rental, a loan sized to retire both liens is generally treated as cash-out. Ask the lender how it classifies the payoff.
Combine with almost no cash back. You can size the loan so little comes out, but cash-out leverage limits and seasoning still apply.
A short appraisal. If value comes in low, the line may stay outstanding. Size the deal with room to spare.
A line on another property. A HELOC secured by a different property is a different case. Confirm title before assuming it must be paid off.
Product labels. Some products sold as investment or DSCR HELOCs are really cash-out refinances that replace the first. Confirm which one is on the table.
LLC-owned rentals. On our network’s investment HELOC programs, LLCs, corporations, and partnerships cannot hold title. A rental already deeded to an LLC would need a vesting change or a DSCR cash-out, subject to lender program eligibility.
Loan order. If a DSCR loan came first and a line followed, the DSCR note may restrict extra liens. A later refinance of the first gives the junior lender a veto again.
Property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs.
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.
Keep, Subordinate, or Pay Off?
| Option | Payments after | First mortgage |
|---|---|---|
| Keep line, subordinate | Two payments | Refinanced, line behind |
| Pay off via cash-out | One payment | Replaced by new loan |
| New investment HELOC | First plus line | Left alone, line added |
For investment properties, our network’s HELOC lines cap at 70% CLTV, up to $500,000 total, with a 700 minimum credit score. Lines on investment properties use a 5-year draw and a 25-year repayment, and the price floats throughout. Availability is limited to Lendmire’s 16 full-service states. If you are deciding how big a line or cash-out should be for a down payment, Lendmire’s comparison of a smaller HELOC versus a larger cash-out refinance for a rental down payment walks through the tradeoff.
A payoff makes the most sense when the line floats, the draw is ending, and the first mortgage is not unusually cheap. It makes the least sense when you would be replacing a low first mortgage to retire a small line.
Frequently Asked Questions
Will my monthly payment go down after a cash-out refinance pays off my HELOC?
Sometimes. A longer term and a fixed schedule can lower it, especially if the line is amortizing. If the line is still interest only, or you give up a cheaper first mortgage, the payment can rise. Lifetime interest often rises either way when the term stretches.
Does the HELOC close when it is paid off in the refinance?
Not automatically. A zero balance leaves the lien recorded until a written closure request is processed and a release is filed. Ask for the closure at the same time you request the payoff letter, then confirm it in the county record.
Can I keep the HELOC when I refinance the first mortgage?
Only if the line’s lender agrees to subordinate. They can refuse. If they agree, you keep two separate payments, and the line’s combined-loan test uses the full credit limit.
Does paying off the HELOC help my DSCR loan?
It changes what the rent must cover. The HELOC payment folds into one qualifying payment, so a larger combined balance means a heavier load on rent. Keeping coverage near or above 1.00 on the larger loan matters for eligibility.
Can I draw on the line again after the payoff?
No. A cash-out refinance gives you one lump sum. If you want revolving access later, that requires a new line, which is a separate approval.
Next Step
If you are weighing a home equity line against a cash-out refinance and want to see how the numbers work, Lendmire can help you compare HELOC options based on the property, the equity available, credit profile, combined leverage, and your goals. Every figure here is subject to lender guidelines and full file review. This is not a commitment to lend.
Most investors find the real decision is not whether one payment beats two. It is whether the rent still carries the larger loan with room left over after the costs the ratio never sees.
