The Quick Read: A refinance replaces your first mortgage, so it can change the payment you already owe. A HELOC (home equity line of credit) leaves that mortgage alone and adds a second loan on top. If your goal is a smaller monthly bill, the refinance is the tool that can do it. If your goal is cash, the HELOC is the tool built for it. Everything below helps you pick between them, or see that you do not need to.
Key Takeaways
- A HELOC does not lower your first-mortgage payment. It adds a second payment.
- A refinance can lower the payment through a lower interest rate, a longer term, or both. Closing costs decide whether it pays off.
- Your current mortgage terms matter most. A strong existing loan is worth protecting.
- A HELOC payment can move, and it usually jumps when the borrowing period ends.
- How long you plan to stay in the home often settles the question.
Are You Solving the Same Problem?
Often you are not. People lump these two products together because both tap the same house. They solve different problems.
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.

There are three common goals:
1. "I want a smaller monthly bill." That points to a refinance. A HELOC cannot get you there on its own.
2. "I need cash for a project or a bill." That points to a HELOC, or to a cash-out refinance, which is a different loan with tighter rules.
3. "I want both." That is where the decision gets real. You may be weighing one new first mortgage against keeping your current loan and adding a line behind it.
Be honest about which goal is actually driving you. Many homeowners start out shopping for one outcome and end up comparing a loan that was never built to deliver it.
This page focuses on the first goal, a lower payment with no meaningful cash out. Lendmire's refinance programs cover this kind of rate-and-term loan, along with FHA, VA, and jumbo options.
Key Terms Defined
Rate-and-term refinance: A new first mortgage that pays off the old one to change the interest rate, the length of the loan, or both, with only incidental cash back.
HELOC: A revolving line of credit secured by your home. You borrow what you need, up to a limit, and pay interest on what you use.
Draw period: The stretch of a HELOC when you can borrow. Payments are often small during this time.
Repayment period: The stretch after the draw period ends. You can no longer borrow, and the balance gets paid down.
Second lien: A loan that sits behind your first mortgage. If the home is sold or foreclosed on, the first mortgage gets paid first.
Break-even point: The month when your total monthly savings equal what the refinance cost you to close.
Mortgage insurance: A charge that protects the lender when your loan is above 80% of the home's value. It cancels at 80% on request and ends automatically at 78%.
Net tangible benefit: A test used on government streamline refinances. The new loan has to leave you measurably better off, such as a lower payment or a move from an adjustable to a fixed loan.
How Does Each Option Change Your Monthly Payment?
A refinance can lower your payment in three ways. A HELOC lowers it in none of them.
A lower interest rate. The new loan replaces the old rate. Same balance, same term, smaller payment. This only makes sense if the market has moved in your favor since you took the original loan.
A longer term. Stretch the balance over more years and each payment shrinks. Here's the catch: you usually pay more total interest. A lower payment bought with a longer term is relief now, paid for later.
Fixed instead of adjustable. Switching out of an adjustable loan may not cut the payment today. It can protect you from future increases. For some borrowers that is the real win.
A HELOC works differently. Your first mortgage keeps its payment, its rate, and its term. The HELOC payment lands on top. The only way a line of credit "lowers" a monthly bill is indirect: you borrow from it to pay down other debt. That moves money around. It does not change the first mortgage.
One more detail. Many HELOCs carry a variable rate, and the payment during the draw period can be small because it covers little more than interest. That small payment looks like relief. It is a feature of the draw period, not a lower cost of borrowing.
Refinance vs. HELOC Side by Side
| Factor | Lower-Payment Refinance | HELOC |
|---|---|---|
| What happens to your first mortgage | Replaced | Stays as is |
| Number of monthly payments | One | Two |
| Rate structure | Can be fixed | Usually variable |
| Payment over time | Steady on a fixed loan | Can rise, then jump at repayment |
| Upfront costs | Full closing costs | Often lower fees |
| Effect on total interest | Longer term raises it | Depends on balance and time |
| Main risk | Costs not recovered if you move | Payment shock; line can be frozen |
How Is a Refinance Underwritten, Step by Step?
Underwriting is the lender's review of whether you and the home qualify. Here is how a standard rate-and-term refinance runs across the wholesale programs Lendmire places files with. Every figure is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Step 1: Pick the structure. A rate-and-term refinance pays off your existing first mortgage and the closing costs, plus a purchase-money second lien if you have one. Cash back is incidental only. On a one-unit principal residence, leverage on a conventional loan can reach 95% of the home's value. It reaches 97% where the existing loan is agency-owned and a first-time-buyer program allows it.
Step 2: Check the mortgage insurance line. Above 80% leverage, mortgage insurance applies. It cancels at 80% of the original value if you have a good payment history, no subordinate liens, and no drop in value. It ends automatically at 78%. Typical published premiums run from 0.58% to 1.86% of the balance annually. That is a range, not a quote. Final terms depend on the lender's guidelines, the property type, and the borrower's complete credit picture.
Step 3: Credit and ratios. Wholesale conventional programs generally start at a 620 decision score. The automated finding governs most files, with a total debt ratio ceiling of 50%. Manually underwritten loans use 36% or 45%, depending on score and reserves. Past credit events carry agency waiting periods: four years from a chapter 7 discharge, seven from a foreclosure, four from a short sale or deed-in-lieu. Documented extenuating circumstances can shorten them.
Step 4: Appraisal and title. A conventional refinance generally uses an appraisal. The lender also confirms you are on title.
Step 5: Weigh costs against savings. This is the break-even question, covered below.
The government streamlines
If your current loan is FHA or VA, you may have a lighter path.
The FHA Streamline is for a loan that is already FHA-insured and current. HUD requires a net tangible benefit, caps cash back at a small amount, and does not allow closing costs to be added to the new loan amount. HUD also notes that some "no cost" refinances are built by charging a higher interest rate. In the wholesale programs Lendmire works with, the streamline carries no appraisal and a limited credit review. An FHA rate-and-term loan with an appraisal reaches 97.75%.
The VA IRRRL (Interest Rate Reduction Refinance Loan) is for an existing VA loan. It carries a 0.5% funding fee unless you are exempt, no VA appraisal, and a net tangible benefit test. There is also a seasoning rule on the existing loan.
Above the conforming loan limit, jumbo lanes take over. They start at a 660 decision score, reach 90% leverage, allow loans to $5,000,000, and use a 50% ratio ceiling on the fixed lanes. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
How Is a HELOC Set Up?
A HELOC skips most of the first-mortgage rewrite. Here is the path.
1. The limit is set. Many lenders base the credit limit on a percentage of your home's appraised value minus what you still owe on the first mortgage, per the Consumer Financial Protection Bureau. Lenders set that percentage differently.
2. You get the disclosures. Federal rules require the lender to give you disclosures and a consumer brochure when it hands you an application.
3. The draw period starts. You can borrow up to your limit. The CFPB gives 10 years as an example of how long that can last. Many plans set the minimum payment from your current balance.
4. Repayment begins. Borrowing stops, and the balance gets paid down.
5. Your first mortgage does not change. It keeps its payment, rate, and term.
The Federal Trade Commission adds two points worth knowing. A HELOC typically has a variable interest rate. And you pay interest only on what you borrow, not on the whole available line. So the headline number is not the whole cost.
Worked Example: The Break-Even Test
These are hypothetical illustrations, not quotes, and they use no dollar figures on purpose.
The refinance break-even. Divide your total closing costs by your monthly savings. The answer is the number of months before you come out ahead.
Picture a homeowner whose refinance saves a modest amount each month, with closing costs equal to about three years of those savings. If she expects to sell in two years, the refinance loses money. If she plans to stay ten years, it wins comfortably. The same loan, two verdicts. That is why time horizon often decides this.
The term-stretch trap. Say a borrower with 20 years left refinances into a new 30-year loan. The payment drops. The clock restarts. He is now paying interest for ten extra years. If the goal is breathing room for a tight stretch, that may be a fair trade. If the goal is to keep total cost down, it is a poor one. Compare total interest, not just the monthly line.
The HELOC alternative. Consider a homeowner with a strong existing first mortgage and a one-time need for cash. A HELOC keeps the good loan in place and applies the new, likely higher, borrowing cost only to the amount she draws. A cash-out refinance would apply the new terms to the entire balance. That is the logic behind the old rule of thumb: keep a low first mortgage, borrow on top of it.
Notice what that example solves. It solves a cash need. It does not lower her payment.
Where the General Rule Breaks
You already have a HELOC. If it sits behind your first mortgage and you refinance, the second lien does not vanish. It either gets paid off or stays and has to be subordinated, meaning moved behind the new first loan. Lendmire's piece How to Subordinate Your HELOC to Refinance Into a Lower Payment covers how that works.
Paying off a HELOC changes the loan type. Under conventional rules, rolling a second lien into a new first mortgage can push the loan into cash-out territory, depending on how that lien was used. Cash-out is a different product. On a one-unit principal residence, conventional cash-out generally tops out at 80% leverage. The mortgage being paid off must be at least 12 months old. A borrower has to be on title for six months, with exceptions for delayed financing, inheritance, and legal awards. Cash-out rules also differ in how much cash you may take. Fannie Mae's announcement capped cash back on limited cash-out loans at a small amount tied to the new balance.
Your first mortgage is already cheap. Replacing it means giving it up. This is the situation where a HELOC, or no new loan at all, tends to beat a refinance.
You hold an FHA or VA loan. The streamlines described above can lower the payment with less paperwork. You cannot streamline a conventional loan into FHA, and the IRRRL only refinances an existing VA loan.
Your goal is an adjustable-to-fixed switch. The payment may barely change. The benefit is stability. Both government streamlines treat that as a recognized gain.
If the property is a rental or second home, leverage drops, since occupancy decides the cap.
Your line gets frozen. The CFPB warns that a HELOC lender may stop further draws if the home's value drops significantly or your finances change. Counting on a line that can vanish is a risk.
Stress-Testing Each Choice
Ask what happens when things go wrong.
If interest rates rise. A fixed refinance does not care. A variable HELOC payment can climb. On a large balance, that adds up.
If the draw period ends. This is payment shock. The small payment you were used to turns into one that includes principal.
If your income drops. Two payments are harder to carry than one. Both loans use your home as collateral. Falling behind on a HELOC could cost you the house.
If home values fall. A refinance is already closed, so it holds. A HELOC limit can be cut or frozen right when you might lean on it.
A Simple Decision Path
| If this describes you | Lean toward |
|---|---|
| Wants a smaller monthly bill, staying put long-term | Refinance |
| Current first mortgage is strong, needs a one-time sum | HELOC |
| Needs steady, predictable payments | Fixed refinance |
| Plans to sell within a few years | Usually neither; run break-even |
| Has an existing FHA or VA loan | Check the streamline first |
| Needs flexible, repeat borrowing | HELOC, with a repayment plan |
This is a starting point, not a verdict. A file can break any of these lines.
Mistakes to Avoid
- Comparing only the monthly payment. A lower payment from a longer term can cost more overall.
- Ignoring closing costs. They have to be recovered through savings.
- Believing a "no cost" refinance is free. The costs are built into the interest rate or the balance.
- Borrowing more than you need. A line makes extra cash easy to reach. Easy is not the same as smart.
- Treating the HELOC rate as the whole price. Fees and the variable structure change the real cost.
- Skipping the tax question. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
What to Ask and What to Gather
Ask each lender how the new loan treats your existing first mortgage. Ask what happens to your payment after the draw period. Ask whether your costs are in the Loan Estimate or folded into the balance. Compare the same scenario across all of them.
Have these ready: your latest mortgage statement, proof of income, your current homeowners insurance, and the details of any second lien. The more your paperwork matches your goal, the easier the comparison.

Frequently Asked Questions
Is a HELOC or a refinance better for lowering my payment?
A refinance. It replaces your first mortgage and can reduce what you owe each month. A HELOC adds a second loan, so your total monthly obligation usually goes up. A HELOC can lower payments indirectly if you use it to clear other debt, but that is a different strategy.
Can I keep my HELOC if I refinance my first mortgage?
Often, yes, but the HELOC lender has to agree to stay in second position. That step is called subordination. Without it, you may have to pay the line off or close it as part of the refinance. Guidelines vary by lender and program.
How long do I need to stay in the home for a refinance to pay off?
Long enough to recover the closing costs through monthly savings. Divide the costs by the monthly savings to get your break-even month. If you expect to sell before that month, the refinance loses money.
Does paying off a HELOC with a refinance count as cash-out?
It can, depending on how the HELOC money was used. Conventional guidelines treat second liens differently depending on that use, and a non-purchase second lien rolled into a new first mortgage may make the loan cash-out. Cash-out carries lower leverage limits and seasoning rules, so confirm the treatment before you apply.
What happens to my HELOC payment when the draw period ends?
Borrowing stops and repayment begins. The payment commonly rises because it now covers principal. If your line has a variable rate, the payment can also move with the market. Plan for the higher payment before the draw period ends.
