The Quick Read: If your goal is one loan instead of two, a cash-out refinance is usually the tool that does it, and a HELOC cannot. A HELOC is a new second mortgage that sits behind your first. It never merges anything. A refinance pays off both liens and replaces them with one new first mortgage. The catch is that paying off a second mortgage often makes the refinance “cash-out,” even if you walk away with no cash.
Here is the honest answer on who each option is for. A cash-out refinance fits the homeowner who wants a single payment and whose current first mortgage has no special value worth protecting. A HELOC fits the homeowner who likes the first mortgage they have and wants flexible access to equity on top of it. Neither is the better product. They solve different problems, and the one that wins depends on what you are keeping and what you are giving up.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, 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 rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
Side-by-Side
| Factor | Cash-Out Refinance | HELOC |
|---|---|---|
| What happens to your first mortgage | Paid off and replaced | Stays as it is |
| Number of loans afterward | One | Two |
| Lien position | New first mortgage | New second mortgage |
| Leverage (primary home) | 80% LTV, one-unit, conventional | Set by lender on combined liens |
| Credit floor | 620 on wholesale conventional programs | Set by each lender |
| Mortgage insurance | Not typical at this leverage | Not part of the product |
| Occupancy | Primary home gets the highest leverage | Lender sets limits by occupancy |
| Documentation | Full income, asset, credit, appraisal | Credit, income, home value |
| Access to funds | One lump sum at closing | Revolving line during draw period |
On the table. Across the wholesale programs placed through Lendmire, the conventional cash-out figure is 80% LTV on a one-unit primary residence, and 75% on two- to four-unit homes and second homes. LTV means loan-to-value: your total loan balance divided by the home’s appraised value. All figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend. For the agency view of how limits shift by occupancy and transaction type, see the Fannie Mae Eligibility Matrix.
Why “Combining” Means Cash-Out More Often Than People Expect
Most borrowers assume that rolling a second mortgage into a new first is a plain rate-and-term refinance. It usually is not. The classification depends on what the second lien originally paid for, not on whether you receive any money.
Here is how it works. If the second mortgage was a piggyback loan used entirely to buy the home, paying it off can stay in the limited cash-out category. That is the same category as a standard rate-and-term refinance. Fannie Mae’s limited cash-out rules allow a second to be paid off only if the entire amount went into the purchase, and the lender has to document that.
If the second funded a kitchen, paid off credit cards, or came from a HELOC drawn for anything other than the purchase, the refinance becomes cash-out. You get cash-out leverage limits, not the higher rate-and-term limits. You also get the seasoning rules. Practically, that means the first mortgage being paid off must be at least 12 months old, and a borrower must have been on title for six months, with exceptions for delayed financing, inheritance, and legal awards.
A HELOC that was drawn partly for the purchase and partly for something else is a trap. The rule requires that the whole lien was purchase money. A mixed-use line therefore lands on the cash-out side. Ask for the old closing statement early. It is the document that settles the question.
This is the point most comparison pages skip. They treat the choice as “new cash or no new cash.” For a reader holding two liens, the real question is how the existing second gets handled.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance is the better fit when you want one loan, one payment, and one set of terms, and your existing first mortgage is not something you are trying to protect. Picture a homeowner whose first mortgage and second mortgage together feel like clutter. The second may carry a variable payment. Merging them trades two moving parts for one.
It also fits when the second lien is a problem to solve. A HELOC’s draw period can end and the payment can change. The CFPB’s HELOC overview notes that a draw period could last 10 years, for example, followed by a repayment period. A lender may also freeze or reduce a line if the home’s value drops or your finances change. If you want certainty rather than a line that can change underneath you, one fully amortizing first mortgage is simpler to plan around.
Run a mental scenario. Say you have a first mortgage at a modest balance and a HELOC you drew down to renovate. You want to stop watching the line, and you would like a single payment you can budget a year out. Your combined balance sits comfortably under 80% of the home’s value. That profile suits a cash-out refinance.
There is one more option worth naming. A separate wholesale lane reaches higher leverage than the standard 80% limit with no mortgage insurance, but only under tighter conditions. It requires a 680 score, a 50% ratio ceiling, a thirty-year fixed rate, a primary residence, a conforming loan balance, and its own six months of seasoning. In Texas, a cash-out on the homestead is capped by the state constitution at the agency figure, and that wholesale lane is not written there. Whether any of this applies depends on lender guidelines and your full file.
The costs on this side are real. A refinance is a new first mortgage, with a full set of closing costs and a fresh term. You replace every feature of your old first mortgage. For some borrowers that is the price of simplicity. For others it is a dealbreaker.
When a HELOC Is the Better Fit
A HELOC is the better fit when your current first mortgage is worth keeping and you need equity access without touching it. A HELOC is a second mortgage. Per the CFPB, if you already have a mortgage, a home equity loan or HELOC is a second mortgage that you pay in addition to the first.
Consider a homeowner who bought or refinanced into a first mortgage on terms that would be hard to match today. Replacing it just to merge in a small second loan means giving up those terms to tidy up the paperwork. In that case, leaving the first alone and using a HELOC, or leaving the existing second in place, can be the more sensible structure. This is a judgment call, and it hinges on the size of the second lien compared to the first.
A HELOC also fits when your need is uneven. Some people want money for a project that unfolds over months, and a revolving line lets you draw as bills arrive and repay as you go. A cash-out refinance hands you everything on day one.
The tradeoffs deserve equal weight. HELOCs typically carry variable payments, built from an index plus a margin, and the CFPB HELOC booklet warns about introductory “teaser” terms that do not last. Lenders can charge certain fees, and some plans require minimum draws. The line can be frozen. And in both options, your home is the collateral. Fall behind and you could lose it.
The HELOC also does not solve your original problem if that problem is “I have two payments.” It adds to the pile or leaves the pile as it was.
What About Keeping Both and Refinancing Only the First?
This is the third path, and it deserves a plain explanation. Suppose you want a new first mortgage but intend to keep your existing second or HELOC. When the first is paid off, the second would automatically jump into first position. Lenders will not allow that. The second-lien holder has to sign a subordination agreement, agreeing to stay behind the new first.
Fannie Mae states that a remaining subordinate lien must be resubordinated to the new first mortgage. If the refinance leaves the second in place and you take no extra cash, it stays in the limited cash-out category. The holder is not automatically obligated to agree, though. Subordination adds a step to the file and can carry a fee, and the approval is not something your new lender controls.
Across the wholesale programs placed through Lendmire, this is where files stall unexpectedly. The borrower assumes the HELOC will simply carry over. Then the HELOC holder takes time to respond, or declines. Asking your second-lien holder about subordination at the start, before you commit to a structure, prevents a late surprise.
Do FHA and VA Streamlines Fold In a Second Mortgage?
No. People often hope so, and the rules say otherwise. An FHA Streamline refinances the existing FHA-insured first mortgage only. HUD’s Streamline page describes it as governed by Handbook 4000.1, and it does not allow closing costs to be financed into the new mortgage amount.
The VA’s Interest Rate Reduction Refinance Loan has the same limit. The VA states that if you have a second mortgage, its holder must agree to make the new VA-backed loan the first mortgage. The second stays. It gets subordinated, not paid off.
So an FHA or VA borrower who wants one merged loan generally needs a different structure, such as a cash-out refinance under the relevant program or conventional financing if eligible. The streamlines are valuable for what they do, including limited credit review and no appraisal on the FHA side, a net tangible benefit test, and for the VA loan a 0.5% funding fee unless exempt. They are just not consolidation tools.
Key Terms Defined
Lien: A legal claim on your home that secures a loan. The first lien gets paid first if the home is sold or foreclosed.
Subordination: An agreement in which a second-lien holder agrees to stay behind a new first mortgage rather than moving up.
Purchase-money second: A second mortgage used entirely to buy the home, usually at the same time as the first.
Seasoning: The minimum age a loan or ownership period must reach before a certain refinance is allowed.
Draw period: The stretch of a HELOC when you can borrow from the line, before repayment begins.
Limited cash-out refinance: A refinance that pays off the existing first mortgage, closing costs, and sometimes a purchase-money second, with only incidental cash back. It is often called rate-and-term.
A Balanced Verdict
Start with one question: what are you trying to keep? If the answer is “my first mortgage as it is,” a HELOC or an untouched existing second is the natural structure. If the answer is “nothing, I want it all simplified,” a cash-out refinance is the one that actually combines the loans.
Then check three things. First, classify the second lien honestly, because that decides whether you face cash-out limits. Second, add up your combined balances against the home’s value and compare that to the 80% one-unit conventional limit, or the wholesale lane described earlier if you fit it. Third, ask whether the payment you would live with, fixed or variable, is one you can budget through the loan’s whole life.
It is genuinely a toss-up for many borrowers, and anyone who tells you otherwise before seeing your file is guessing. Lendmire’s piece Lower Payment vs Cash-Out Refinance to Combine a First Mortgage and HELOC walks through that tradeoff in more depth. For a related case, see how a second-lien HELOC compares with a cash-out refinance for a low fixed mortgage.
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the cash-out refinance programs and the equity each one reaches.
Frequently Asked Questions
Can I roll my HELOC into a refinance?
Yes, in most cases, as long as the lender approves the structure. A new first mortgage can pay off the HELOC at closing. If the HELOC was not used entirely to buy the home, the transaction is generally treated as cash-out, so cash-out leverage limits and seasoning apply. Guidelines vary by lender and program.
Is paying off my second mortgage always cash-out?
No. A second used entirely to purchase the home can be paid off within a limited cash-out refinance, and the lender must document that. A second that funded anything else makes the refinance cash-out, even if you receive no cash. A HELOC drawn partly for other uses does not qualify as purchase money.
What is subordination, and can I keep my HELOC open?
Subordination is the second-lien holder’s written agreement to stay behind your new first mortgage. If you want to keep a HELOC after refinancing, the holder generally has to agree. It is not automatic, it can add a step and a fee, and the holder may decline.
Will I lose my current first mortgage terms if I combine?
Yes. A cash-out refinance replaces the existing first mortgage, including its term and payment structure. If those terms are valuable to you, keeping the first and using a second lien may fit better. Comparing the full new terms against what you hold now is the sensible check.
Can an FHA or VA streamline absorb my second mortgage?
No. Both streamlines cover only the existing government-backed first mortgage, and the second lien stays in place and gets subordinated. Merging the two loans generally calls for a cash-out refinance or conventional financing, if you are eligible.
