The Quick Read: A cash-out refinance swaps your first mortgage and your home equity line of credit (HELOC) for one new first mortgage. The new loan pays off both liens, closes the line, and hands you any extra cash. It works when your combined balances fit under the equity cap and one payment is worth more to you than the first mortgage terms you give up. Plan the numbers before you apply, because the first mortgage is the piece that changes most.
Key Takeaways
- A cash-out refinance does not “add on” to your HELOC. It replaces your whole first mortgage and pays the line off from the proceeds.
- On a conventional loan, the cap is 80% of the home’s value on a one-unit primary residence. Every lien you pay off and every cost you finance counts against it.
- Seasoning rules apply: the first mortgage being paid off must be at least 12 months old, and you need six months on title, with exceptions.
- Your current first mortgage is the real cost. If it is better than today’s market, replacing it can cost more than the HELOC ever did.
- Once the line is closed, you have no revolving access to your equity. Plan for future needs before you sign.
What Does a Cash-Out Refinance Actually Replace?
It replaces the first mortgage, not just the equity slice. A HELOC sits behind your first mortgage and leaves it alone. A cash-out refinance pulls both out and puts one new loan in their place.
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: 7.18% as of November 5, 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.
Picture a homeowner with a first mortgage and a HELOC drawn to pay for a kitchen and some debts. The line has a variable payment that moves with the market. The homeowner wants one steady payment. A cash-out refinance does that. The title company pays off the first mortgage and the HELOC at closing, and the borrower receives whatever is left.
That is the trade. You get one lien, one payment and a payment that no longer swings on a variable line. You also reset the first mortgage: new balance, new term, new interest rate.
Lendmire’s cash-out refinance programs page lays out how the conventional options are structured. This guide covers the planning work that comes before any application.
Key Terms Defined
HELOC: a revolving line of credit secured by your home. You borrow, repay and borrow again during a draw period, usually at a variable rate.
Cash-out refinance: a new first mortgage larger than the balance you owe. It pays off the old loan or loans, and you keep the difference.
LTV (loan-to-value): your loan balance divided by the home’s appraised value. A combined version adds every lien on the home.
Seasoning: the waiting period a lender wants before you refinance. It counts how long you have owned the home or held the loan being paid off.
Limited cash-out (rate-and-term) refinance: a refinance that pays off the existing first mortgage and closing costs, with only small incidental cash back.
Lien release: the recorded document showing a paid-off loan no longer has a claim on your home.
Step by Step: How to Plan the Swap
Planning beats rushing. Working through the steps in this order helps you catch problems before you apply.
1. List every lien. Write down the first mortgage balance, the HELOC balance and the HELOC’s credit limit. Note whether the HELOC was used to buy the home or for something else.
2. Decide why the HELOC no longer fits. Common reasons are a variable payment you dislike, a draw period about to end, or a balance you want folded into something predictable. If you cannot name the reason, you may not need to refinance. If the draw period is the issue, Lendmire’s piece How to Plan and Use a Cash-Out Refinance to Pay Off a HELOC Whose Draw Period Ended goes deeper.
3. Estimate your home’s value honestly. The appraisal sets the value, and value drives every cap. A generous guess leads to a disappointing result.
4. Run the equity math. Add the first mortgage, the HELOC balance, financed closing costs and any cash you want. Divide by estimated value. Compare it to the cap.
5. Check seasoning. Confirm the first mortgage’s age and how long you have been on title.
6. Check credit and income. The loan is fully underwritten. Lenders look at credit score, income, debt ratios and reserves.
7. Compare against staying put. Use the break-even check below before you commit.
8. Apply and review the disclosures. You receive a Loan Estimate, then a Closing Disclosure before you sign.
9. Confirm the line is closed. Get written proof the HELOC is paid off, closed, and released from your title.
How Much Equity Do You Need?
You need your combined liens, plus financed costs and cash out, to land at or under the cap. On a conventional cash-out refinance, that cap is 80% on a one-unit primary residence. It is 75% on two- to four-unit primary residences, second homes and investment property, so occupancy sets the leverage. The Fannie Mae Eligibility Matrix publishes those caps, and it also ties reserve requirements to files with higher debt ratios. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Here is a hypothetical, with every figure as a percentage of the home’s value:
| Item | Share of value |
|---|---|
| First mortgage balance | 55% |
| HELOC balance (drawn) | 15% |
| Combined liens | 70% |
| Room left under an 80% cap | 10% |
That 10% of room covers financed closing costs and any cash you want. Spend it on cash, and costs have nowhere to go.
Now flip it. Say the first mortgage is 68% and the HELOC is 14%. That is 82% before any costs. The refinance does not fit under an 80% cap unless the appraisal comes in higher or you bring cash to closing to pay the balance down.
One common mistake: borrowers read “80% LTV” and think they can borrow 20% of the home’s value. The cap covers all liens. Whatever you already owe comes out of that 80% first. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Credit counts too. The wholesale conventional programs start at a 620 decision score, with a total debt ratio ceiling of 50% on the automated findings. Manually underwritten files run tighter. All of it is subject to lender guidelines and full file review.
Is It Worth It? A Break-Even Check
It is worth it when the monthly savings and risk reduction outweigh the one-time cost and the first mortgage you give up. Here is a simple method, with no numbers needed until you have a real quote.
1. Add your current total monthly payment: first mortgage plus HELOC.
2. Get the estimated payment on the new loan from your Loan Estimate.
3. Subtract to find the monthly difference.
4. Take the total closing costs the new loan will carry, whether paid in cash or financed.
5. Divide the costs by the monthly difference. The answer is the number of months until the swap pays for itself.
If you expect to keep the home longer than that, the math supports it. If you might sell or refinance again sooner, it may not.
Three things distort this check:
- Your existing first mortgage terms. If your current first mortgage has more favorable terms than the market offers today, a cash-out refinance replaces them on the whole balance, not just the portion you are borrowing against.
- Term reset. A fresh 30-year term lowers the payment but stretches the payoff. Compare total interest, not just the monthly number.
- Financed costs. Costs rolled into the loan show up on your Loan Estimate and Closing Disclosure as “Closing Costs Financed.” They also use up equity room under the cap.
The CFPB’s HELOC booklet compares the products side by side. It notes that a cash-out refinance lets you keep making one mortgage payment, and that its closing costs are generally higher than a HELOC’s.
Your Options Side by Side
Replacing a HELOC is not the only exit. Pick the route that matches the problem.
| Route | What it does | Best when |
|---|---|---|
| Cash-out refinance | New first mortgage pays off first lien and HELOC | You want one payment and can afford a reset |
| Limited cash-out refinance | Pays off first mortgage, little cash back | The HELOC was purchase money, or is the only lien |
| Keep the HELOC, convert part to fixed | Locks a portion of the balance | Your first mortgage is worth keeping |
| New HELOC or home equity loan | Adds or replaces a second lien | You want to leave the first mortgage alone |
Some HELOCs let you convert part or all of the balance to a fixed rate. The CFPB notes the fixed rate is usually higher than the variable rate but more predictable. If a conversion solves your problem, you may not need a new first mortgage at all.
Where the General Rule Bends
The rule of thumb is simple: a cash-out refinance replaces the first mortgage and the HELOC, and the 80% cap applies. These cases change the answer.
The HELOC is your only mortgage. Some homeowners paid off their first mortgage years ago and kept a HELOC that now sits in first position. The Fannie Mae Selling Guide’s limited cash-out rule allows paying off a first-lien HELOC without making the deal a full cash-out. That can mean different leverage limits and pricing, subject to lender guidelines.
A non-purchase HELOC sits behind your first mortgage. This is the usual case. A limited cash-out refinance can pay off a purchase-money second lien. A HELOC used for repairs, debt payoff or other spending generally pushes the loan into full cash-out. That means the 80% cap on a one-unit primary residence, not the 95% available on rate-and-term.
Cash back is small on a limited cash-out. If your HELOC qualifies as a purchase-money second, the agencies allow only incidental cash. Fannie Mae allows the lesser of 2% of the new loan amount or $2,000.
Seasoning. On a conventional cash-out, the first mortgage being paid off must be at least 12 months old, counted note date to note date. You also need six months on title. Exceptions exist for delayed financing, inheritance and legal awards. A HELOC in first position has its own exception to the 12-month test. Check which clock applies to you.
You paid cash for the home. Delayed financing lets a cash buyer take a cash-out loan soon after purchase when the conditions are met, including documenting where the purchase funds came from. Cash-out pricing and requirements still apply. The Selling Guide’s cash-out section covers the conditions.
A Texas homestead. The state constitution caps a cash-out on a homestead (a Section 50(a)(6) loan) at 80% of the home’s value, whatever the occupancy or property type. The wholesale no-mortgage-insurance lane, which reaches 89.99% LTV on qualifying files, is not written there.
Government streamlines are not cash-out tools. The FHA Streamline and VA IRRRL refinance an existing FHA or VA loan with limited paperwork, but neither puts cash in your pocket or pays off a HELOC. If you have an FHA or VA loan and want cash, you are looking at a full cash-out under that program’s own rules.
A second home or rental. Occupancy sets the leverage. A cash-out on a second home or an investment property caps at 75%, not 80%.
The higher-leverage lane. One wholesale conventional lane reaches 89.99% LTV with no mortgage insurance. It requires a 680 score, a 50% ratio ceiling, a thirty-year fixed rate, a primary residence and a conforming loan balance. It carries its own six months of seasoning. On files that fit it, this lane can create real room for a drawn HELOC and costs. It is the exception to the usual rule that cash-out leverage stops at 80%. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
What Happens to the HELOC at Closing?
The title company pays it off from your loan proceeds, and the line should close. Do not assume that happens on its own.
Here is what to do:
- Ask for a payoff statement early. A drawn line has interest that keeps accruing until payoff.
- Request written confirmation that the HELOC is paid and the account is closed. An open line with a zero balance can still be drawn on.
- Watch for the lien release. The lender should record a release against your property. Check your title records afterward.
- Know what stays open. If you want to keep the line, the new first mortgage has to work around it. The HELOC lender may need to agree to stay in second position. That changes how the loan is classified and how much equity it can reach.
You also have a short right to cancel. After closing a refinance of your primary residence, you can generally back out for a limited window with no reason. If you cancel, you still owe the original loan. Funds are usually released after that window ends. The CFPB’s closing-documents guidance explains the Loan Estimate, the Closing Disclosure and the notice of right to cancel.
When to Stay, Convert or Refinance
A practitioner’s if/then, stripped down:
| Your situation | Likely best route |
|---|---|
| First mortgage is better than the market; HELOC balance is small | Keep it; consider converting the HELOC balance to fixed |
| Variable payment is the main worry; first mortgage is average | Cash-out refinance can fold both together |
| Draw period ends soon and you want a single steady payment | Cash-out refinance, if equity fits |
| Combined liens run over the cap | Pay the HELOC down first, or wait for value to rise |
| HELOC was purchase money or your only lien | Ask about limited cash-out |
| You may need to borrow again later | Keep or restructure the line; a cash-out leaves no revolving access |
That last row matters. A HELOC can be reduced or frozen if your home’s value falls, according to the CFPB. A cash-out refinance delivers cash once. After closing, the equity you did not borrow is not on call. Weigh that against the risk that a line could shrink at the wrong time.
Whichever route you choose, your home secures the loan. Missing payments on either product puts the home at risk.
Common Mistakes (and a Pre-Application Checklist)
Mistakes that cost borrowers the most:
- Ignoring the first mortgage and focusing only on the HELOC.
- Forgetting that financed closing costs use up room under the cap.
- Assuming six months of ownership unlocks every cash-out. The first mortgage’s age matters too.
- Closing the swap without a written confirmation the line is closed.
- Rolling everything into a new 30-year term without comparing total interest.
- Spending the extra cash without a plan, then missing the flexibility of the line.
Before you apply, check these:
- Current first mortgage balance and its note date.
- HELOC balance, credit limit and what it paid for.
- A realistic home value estimate and the combined liens divided by it.
- Credit score, income documents and monthly debts.
- How long you plan to stay in the home.
- Whether you need borrowing access after closing.

Frequently Asked Questions
Can a cash-out refinance pay off a HELOC?
Yes. The new first mortgage pays off your existing first mortgage and the HELOC at closing, and the line is closed. Any leftover proceeds go to you. Whether it counts as a full cash-out or a limited cash-out depends on the HELOC’s lien position and what the money paid for.
How much equity do I need to replace a HELOC with a cash-out refinance?
Your combined liens, financed costs and any cash taken must fit under the cap. Conventional cash-out is 80% LTV on a one-unit primary residence and 75% on two- to four-unit primary residences, second homes and investment property. The wholesale no-mortgage-insurance lane reaches 89.99% for qualifying primary-residence files. Appraised value decides the final number. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Will I lose my low first-mortgage interest rate?
Yes. A cash-out refinance replaces the entire first mortgage, so the new loan carries the new interest rate and term across the full balance. If your current first mortgage is better than the market, giving it up can outweigh the other benefits of the swap. Compare it against keeping the loan and converting or paying down the HELOC instead.
Does a first-lien HELOC change the rules?
Yes, it can. Fannie Mae’s guide allows a limited cash-out refinance to pay off a first-lien HELOC, and a HELOC in first position also has its own exception to the 12-month seasoning test. That may mean more leverage than a full cash-out. Lender guidelines and your file decide how it is classified.
Does the right to cancel apply to a cash-out refinance?
Generally yes, on a refinance of your primary residence. You get a short window after closing to cancel with no reason, and you still owe the original loan if you do. Funds are usually released after the window ends. The window does not apply to purchase loans.
