The Quick Read: It depends on why the HELOC was opened and which loan program you use. If the HELOC was a purchase-money second, a rate-and-term refinance can pay it off. If you opened it later, to remodel, pay tuition or clear cards, a conventional loan treats the payoff as a cash-out refinance. FHA Streamlines and VA IRRRLs can’t absorb a HELOC at all.
The practical rule: to roll a HELOC in, use a cash-out refinance. To keep it, get a subordination agreement from the HELOC lender. Everything below is subject to lender guidelines and full file review.
Refinance savings and break-even estimate
The starting figures are an example value with a balance in proportion and a placeholder for costs. Replace them with yours, and enter the current rate from your statement.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

What Does "Rolling In" a HELOC Actually Mean?
Rolling in means the new first mortgage pays off the HELOC at closing. The debt doesn't disappear. It moves into a bigger first loan with one payment and one term.
One question usually shapes the file: what was the HELOC used for? That answer can decide the loan type, the leverage cap and the pricing tier. Not the balance. The purpose.
Two terms matter here. A rate-and-term refinance (also called limited cash-out) replaces the existing first mortgage, covers closing costs and a purchase-money second, and allows only incidental cash back. A cash-out refinance lets the new loan exceed those payoffs and covers any non-purchase-money second lien.
Does Paying Off a HELOC Count as Cash-Out?
Usually yes. Fannie Mae's subordinate financing rules treat the payoff of a non-purchase-money second lien as a cash-out refinance, with or without extra cash to the borrower. Most HELOCs are opened after the purchase, so most fall in this bucket.
The exception is a second lien used to buy the home. A piggyback second from the original purchase can be paid off in a rate-and-term refinance. The lender wants proof: the original purchase settlement statement or the purchase title policy showing the second.
Here is where files stall. A borrower says the HELOC was "for the house" because it paid for a kitchen. That is not purchase money. Only money used to acquire the property counts.
A related note: Fannie Mae's cash-out section also describes an energy-improvement exception. Debt used solely for energy improvements, such as a PACE loan, can be paid off without losing the limited classification. A separate disaster-repair exception exists for HELOC draws made after a declared disaster. Both are narrow. Don't assume either applies.
How Does the Program Change the Answer?
Program type decides whether a roll-in is even possible. Here is the side-by-side.
| Program | Can it pay off a HELOC? | What happens to the HELOC |
|---|---|---|
| Conventional rate-and-term | Only if purchase money | Purchase-money second paid off; any other HELOC stays and needs subordination |
| Conventional cash-out | Yes | Paid off at closing |
| FHA Streamline | No | Stays, must be resubordinated |
| VA IRRRL | No | Stays, holder must subordinate |
| Jumbo | Program-dependent | Depends on lender and purpose |
On the government side, the rules are firm. VA's IRRRL page says no loan other than the existing VA loan may be paid from the proceeds, and that you may not receive cash. A second-mortgage holder has to agree to subordinate. FHA Streamlines work the same way in practice: the first FHA mortgage gets refinanced, nothing else gets folded in, and an existing second has to be resubordinated.
The benefit of those streamlines is that they ask little of you. The IRRRL needs no VA appraisal, and the FHA Streamline needs no appraisal and only a limited credit review, though both require a net tangible benefit. The cost is that your HELOC doesn't go anywhere.
What Leverage Limits Apply When the HELOC Is Paid Off?
Cash-out leverage is tighter than rate-and-term. On the conventional programs Lendmire works with, a cash-out refinance on a one-unit primary residence tops out at 80% loan-to-value. Rate-and-term runs to 95% on the same property, and to 97% in the first-time-buyer programs where the existing loan is agency-owned. Those are guideline figures, not promises.
That gap is the whole story for many borrowers. Picture a homeowner who bought with 5% down, has built decent equity and opened a HELOC for repairs. Combined, the first and the HELOC may sit near 75% of value. A cash-out refinance at 80% can take both out. The same homeowner at 85% combined may find that a conventional cash-out refinance is a poor fit for wrapping in the HELOC, and has to look at keeping it, paying it down, or a different structure. Every figure here varies by lender and program.
Seasoning also applies. For a conventional cash-out, the first mortgage being paid off generally has to be at least 12 months old, measured note date to note date, and a borrower must have been on title for six months. There are exceptions for delayed financing, inheritance and legal awards. A HELOC's own age matters less, but a very recent draw draws attention. Expect a question about it. Final terms depend on lender guidelines, property type, leverage, and the borrower's complete credit picture.
Texas is its own case. Cash-outs on a Texas homestead are capped by the state constitution. Other states have equity rules too, so check yours.
What If You Want to Keep the HELOC?
You can, but the HELOC lender has to cooperate. If the old first is paid off and the HELOC stays, the HELOC would jump into first position. No new first-mortgage lender will accept that. So the HELOC must be paid off or resubordinated.
Fannie Mae's job aid defines a resubordinated lien as a subordinate lien that isn't paid off in a refinance and keeps its junior position, based on the junior lender's written agreement. That written agreement is the document you need.
Here's the catch: the HELOC lender can say no. The CFPB notes that you may need that lender's approval and that it can refuse. If it does, you may have to pay off the HELOC to refinance.
Subordination also adds friction. Some HELOC lenders charge a fee, some freeze the line during review, and the process runs on the HELOC lender's schedule, not yours. A frozen line is a real problem if you're mid-project.
Leverage still counts when the HELOC stays. Lenders add every subordinate lien into combined loan-to-value. A large unused credit line can weigh on the ratio even if the balance is small, depending on how the lender counts it. Ask early.
Is Rolling It In the Right Move?
Rolling in is a math question first, a convenience question second. Most borrowers lead with the second and get hurt by the first.
| Your situation | Likely better move |
|---|---|
| First mortgage is a low one you'd give up | Keep it; seek HELOC subordination or leave both alone |
| First mortgage is at or above today's market | Cash-out refinance can make sense |
| HELOC is variable and you want one fixed payment | Cash-out refinance, if leverage allows |
| Existing FHA or VA loan | Streamline or IRRRL; HELOC stays |
| Combined leverage over the cash-out cap | Pay the HELOC down first, or keep it separate |
The trap is the low first mortgage. A cash-out refinance replaces it. You don't get to keep the old first and fold in only the HELOC. So the real test is blended cost. Take what you pay on the old first and the HELOC together, weighted by balance, and compare it to the new single loan plus closing costs. Then ask how many years it takes for savings, if any, to cover those costs. If you'll move before then, skip it.
Term matters too. The CFPB's home equity guide cautions that a cash-out refinance means paying back over a longer period, so the balance falls more slowly. Moving a short-lived HELOC balance into a fresh thirty-year loan lowers the monthly bill and stretches the debt. Not the same thing as saving money.
What Does the Lender Need to See?
A clean roll-in file has a short document list. Missing pieces cause most of the delay.
- A current HELOC statement showing balance, limit and draw history.
- A payoff request to the HELOC lender, plus its written closure or release instruction if you want the line closed. A zero balance alone doesn't close a line.
- Purchase documents if you claim the second was purchase money: the settlement statement or title policy.
- A subordination agreement if the HELOC stays.
- An appraisal. Conventional and FHA cash-out loans generally use a full appraisal. The IRRRL doesn't.
- Income, asset and credit documents for a standard review. The wholesale conventional programs start at a 620 decision score, the automated finding governs most files, and the total ratio ceiling is 50%. Manually underwritten loans run tighter ratios.
Mortgage insurance applies above 80% loan-to-value on conventional loans. It can be cancelled at the borrower's request at 80% of original value, with good payment history and no subordinate liens, and must end automatically at 78%. That's the Homeowners Protection Act, and it's why leaving a HELOC in place can matter later. A subordinate lien can block a cancellation request.
Mistakes That Sink These Files
Four show up repeatedly.
1. Calling a renovation HELOC "purchase money." It isn't. The file gets reclassified to cash-out, and the leverage cap drops.
2. Assuming the HELOC survives automatically. It survives only if its lender signs.
3. Expecting a Streamline or IRRRL to swallow the HELOC. Neither program pays off a separate HELOC on its own.
4. Ignoring the closed-line step. Paying the balance doesn't end the line. Ask for written closure.
Three Business Days to Change Your Mind
Refinancing a primary residence with a new creditor carries a right to cancel. The CFPB explains that you have three business days after closing on a refinance of your principal home. Funds don't move until that window passes. If required notices were defective, the right can extend longer. It applies to your principal dwelling only, so second homes work differently.
Key Terms Defined

Net tangible benefit: A required improvement, such as a lower cost or more stable loan, for FHA and VA streamlines.
Frequently Asked Questions
Can I keep my HELOC open after refinancing my first mortgage?
Yes, if the HELOC lender signs a subordination agreement. Without it, the new lender won't close, because the HELOC would otherwise move into first position. The lender can refuse, and some freeze the line while they review. Plan for that before you schedule anything.
Is paying off a HELOC always cash-out?
No. It's rate-and-term only when the HELOC was a purchase-money second. A HELOC opened after you bought, for any reason, makes the new loan a cash-out refinance on conventional programs. Lenders ask for the purchase settlement statement or title policy to verify.
Can I roll a HELOC into an FHA Streamline or VA IRRRL?
No. Both refinance only the existing government first mortgage. The HELOC stays in place and its holder must subordinate. VA also bars cash from IRRRL proceeds. If you want the HELOC gone, that points to a cash-out refinance instead, which is a different product with different rules.
Will I lose my low first-mortgage rate?
Yes. A cash-out refinance replaces the whole first mortgage, so the old terms go with it. That's why a blended-cost comparison matters. If the old first is well below current market, keeping both loans, or seeking subordination, often beats rolling in.
What if my combined balance is too high for cash-out?
Conventional cash-out on a one-unit primary residence caps at 80% loan-to-value. If both loans together exceed that, you can pay the HELOC down first, keep it and seek subordination, or review other programs. Which route fits depends on the file and lender guidelines.
