The Quick Read: Only a cash-out refinance can turn a 15-year mortgage into a 30-year one. A home equity loan leaves your first mortgage alone and adds a second loan with its own payment. If the goal is a longer term and cash, the refinance does both jobs. If you only want cash and your current loan is working, a home equity loan is the gentler fit.
A cash-out refinance replaces your first mortgage with a new, larger one, and you pocket the difference. A home equity loan sits behind the first mortgage as a separate lien. Neither option is “cheaper” in the abstract, because each one solves a different problem.
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.
Side-by-Side
The table below compares the two on structure and eligibility, not pricing. Figures reflect the conventional cash-out lane Lendmire arranges through wholesale lenders, subject to lender guidelines and full file review.
| Factor | Cash-Out Refinance | Home Equity Loan |
|---|---|---|
| What happens to your first mortgage | Paid off and replaced | Stays in place |
| Can it change 15 years to 30? | Yes | No |
| Number of payments | One | Two (first plus second) |
| Leverage (1-unit primary home) | Up to 80% LTV; one wholesale lane reaches higher | Set by the second lender’s combined limit |
| Credit floor | Wholesale conventional starts at a 620 decision score | Varies by lender |
| Mortgage insurance | Above 80% LTV, with one wholesale exception | Typically none on the second loan |
| Seasoning | First mortgage 12+ months old; 6 months on title | Varies by lender |
| Documentation | Full new-loan file and appraisal | Valuation plus income and credit review |
LTV means loan-to-value: your loan balance divided by the home’s appraised value. Seasoning is the waiting period a lender wants before it will let you refinance or borrow against a property.
What Does “Changing From 15 to 30 Years” Actually Require?
It requires refinancing the first mortgage. That is the whole point of this comparison, and most articles treat it as a footnote.
Your 15-year loan has a note, a balance, and a payoff date. A home equity loan does not touch any of them. You would still owe the remaining 15-year schedule, plus a second payment on top. Only a new first mortgage can reset the clock to 30 years.
The CFPB’s guide on using home equity says a cash-out refinance may extend the time it takes to pay off your mortgage, and that your interest rate and other loan terms change. It describes a home equity loan as a second mortgage with a separate payment, usually at a fixed rate.
One more wrinkle. A refinance that only changes your term and takes out little cash is classified differently from a cash-out. Fannie Mae’s Selling Guide treats these as limited cash-out transactions, where the new loan pays off the existing first mortgage and closing costs with only small cash back. Across the wholesale programs Lendmire works with, a limited cash-out refinance on a one-unit primary home can reach 95% LTV. A standard cash-out is written at up to 80% on that same home, apart from the one wholesale lane described below. So if you want a 30-year term and only a small amount of cash, you may land in the more generous lane. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance fits when you want the term change itself, not just the cash.
Picture a homeowner ten years into a 15-year loan. The payment strains the budget, and they also have a renovation to fund. One new first mortgage handles both. They get a single payment, and the required monthly amount on the larger balance is typically lower stretched over 30 years than it was over the old schedule.
It also fits when your existing first mortgage no longer suits you. You may want to drop an adjustable rate for a fixed one, or fold a second lien into a single loan. A home equity loan cannot do either.
Leverage matters here. Lendmire’s cash-out refinance programs page lays out how conventional cash-out works: up to 80% LTV on a one-unit primary residence, and 75% on two- to four-unit primary residences and on second homes. Occupancy sets the leverage, so a second home gets a lower cap than a primary home. In Texas, a cash-out on a homestead is capped at 80% of the home’s value by the state constitution. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Seasoning applies too. The first mortgage being paid off should be at least 12 months old, and one borrower should have been on title for 6 months, with exceptions for delayed financing, inheritance, and legal awards.
There is also a wholesale lane that reaches 89.99% LTV with no mortgage insurance, which is higher than the standard cash-out limits above. It requires a 680 score, a 50% total ratio, a 30-year fixed rate, a primary residence, a conforming balance, and its own six months of seasoning. It is the one exception to the mortgage-insurance rule, and it is not written in Texas. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The cost of choosing the longer term
Be clear-eyed about the trade. A longer loan keeps your balance higher for longer, so you usually pay more total interest. A lower payment is not the same as saving money. The 30-year term also adds years to your payoff date, which matters if you are near retirement.
One practical fix: take the 30-year term for flexibility, then keep paying at your old 15-year pace when the budget allows. You keep the safety valve without giving up the payoff schedule. That discipline is yours to supply. The lender will not enforce it.
When a Home Equity Loan Is the Better Fit
A home equity loan fits when your first mortgage is the best part of your financing and you only need cash.
Say you have a 15-year loan you are happy with, and the balance is already well along. You need money for a one-time expense. Leaving the first mortgage alone means you keep its schedule, its payoff date, and everything you have already paid down. The second loan has its own term, so you can choose a shorter repayment and retire it on its own timetable.
It also tends to suit smaller cash needs. The CFPB notes that lenders typically want you to keep roughly 10% to 20% of your home’s value as equity, a general statement rather than a program rule. If you are well inside that cushion, a second lien may be enough.
The downsides are real. You carry two payments. Combined leverage limits vary by lender. And the second loan is secured by your home, just as the refinance is. Miss payments on either and the home is at risk.
A home equity loan will not shrink your required payment, though. If the real problem is a payment that strains the budget, adding a second loan makes it heavier, not lighter. In that case only the refinance addresses the cause.
Costs, Cancellation, and Credit: What Applies to Both
Some rules cut across both options.
Closing costs. The CFPB says you often pay closing costs on a cash-out refinance. A second mortgage has its own costs. Compare the Loan Estimate for each side by side, since both are consumer mortgages and both come with one.
Right to cancel. On a principal residence, both a refinance and a home equity loan generally carry a three-business-day right to cancel after closing. The CFPB’s rescission page explains that business days include Saturdays but not Sundays or legal public holidays. If you cancel a refinance, you still owe the original loan.
Mortgage insurance. On the conventional path, insurance applies above 80% LTV, with the wholesale no-MI cash-out lane above as the exception. You can request cancellation at 80% of original value with a good payment history, no subordinate liens, and no drop in value. The servicer must end it automatically at 78%. Lendmire’s conventional program sheet lists typical annual premiums of 0.58% to 1.86% of the balance. That is the sheet’s range, not a quote. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Credit. Wholesale conventional programs start at a 620 decision score, and the automated finding governs most files, with a total ratio ceiling of 50%. Manually underwritten loans use ratios of 36% or 45%. After a credit event, the agencies set waiting periods: four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu, shorter with documented extenuating circumstances.
Taxes. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
What About the Government Streamlines?
If your 15-year loan is FHA or VA, a streamline may look attractive. For this particular move, it probably is not.
The FHA Streamline and the VA IRRRL are rate-and-term tools for existing FHA and VA loans. Both require a net tangible benefit, meaning the refinance must help you financially in a measurable way. HUD’s Handbook 4000.1 defines that benefit in terms like a reduced combined rate, an adjustable-to-fixed change, or a shorter term. Stretching 15 years to 30 is the opposite of a shorter term, so it would have to pass on the rate side instead. Neither streamline gives you cash out. Ask a broker to check the current handbook limits on term extensions before you count on either.
A Simple Decision Path
Use these questions in order:
1. Do you want a 30-year term? If yes, only a refinance works. Stop here.
2. Do you also need meaningful cash? If yes, compare a cash-out against a limited cash-out. The limited version allows higher leverage but only small cash back.
3. Is your current loan worth keeping? If you like its schedule and balance, a home equity loan protects it.
4. Can you carry two payments? If not, the second loan is the wrong tool.
5. Will you keep paying at the old pace? If yes, the 30-year term gives flexibility without the full interest cost.
Equity matters at every step. Both products rely on your appraised value, and a drop in value can narrow your options.
Common Mistakes
- Assuming a home equity loan can lengthen the first mortgage. It cannot.
- Treating the lower payment as savings. It can mean more interest over the life of the loan.
- Ignoring occupancy. A second home or investment property gets a lower leverage cap than your primary residence.
- Forgetting the payoff date. Thirty years from now is a different retirement than fifteen years from now.
- Skipping the comparison of costs. Compare each Loan Estimate line by line.
The Balanced Verdict
Neither option wins on every file. The refinance is the only route to a 30-year term, and it suits a homeowner whose real problem is the payment. The home equity loan is the better tool for someone whose real problem is a one-time cash need and who likes the first mortgage they hold.
If you are on the fence, the cost of the longer term is the deciding variable. Extra years and extra interest are the price of the lower required payment. Pay that price on purpose, and consider keeping your old payment pace.

Frequently Asked Questions
Can a home equity loan turn my 15-year mortgage into a 30-year mortgage?
No. A home equity loan leaves your first mortgage and its remaining term untouched and adds a separate second loan. Only refinancing the first lien can change its term. A homeowner who wants a longer term therefore needs a refinance, while a home equity loan suits someone who wants to keep the current loan as it is.
Will moving from 15 to 30 years lower my payment?
Usually, yes, on that loan. Spreading the balance over more years generally reduces the required monthly payment. The trade-off is more years of payments and typically more total interest. The CFPB’s guide notes that a cash-out refinance may extend your payoff timeline, so weigh the lower payment against the longer horizon.
How much equity do I need for a cash-out refinance?
On the conventional path, the cap is 80% LTV on a one-unit primary residence and 75% on two- to four-unit primary residences and second homes. On a one-unit primary residence, that means keeping at least 20% equity. A separate wholesale lane reaches 89.99% LTV with no mortgage insurance at a 680 score, subject to lender guidelines and file review.
Is a limited cash-out refinance the same as a cash-out?
No. A limited cash-out pays off your first mortgage, closing costs, and certain purchase-money seconds, with only incidental cash back. On a one-unit primary home it can reach 95% LTV. At Fannie Mae, cash back is limited to the lesser of 2% of the new loan amount or $2,000. At Freddie Mac, the limit is the greater of 1% of the new loan amount or $2,000. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Can I cancel after closing?
Often, yes. A refinance or home equity loan on your principal residence generally carries a three-business-day right to cancel. Business days include Saturdays but not Sundays or legal public holidays. If you cancel a refinance, the original loan stays in place. Missing disclosures can extend the window.
