HELOC vs HELOAN: which way to tap your home equity?
HELOC vs HELOAN — understand how each works, what they cost, and which one fits your situation before you put your home on the line.
You've built equity in your home. Now you want to use it. The question is whether you need a line you can draw from over time or a lump sum you repay on a fixed schedule.
That single distinction, flexible access versus one-time payout, is the core difference between a HELOC and a HELOAN. Everything else, the rate structure, the payment mechanics, the tax rules, flows from it.
Both products use your home as collateral. Both tend to carry lower interest rates than credit cards or personal loans because of that. And both can be a smart move or a costly mistake depending on whether you pick the right one for the job.
What is a HELOAN?
A home equity loan, commonly called a HELOAN, is a lump-sum loan secured by the equity in your home. You apply for a specific dollar amount, get it all at once at closing, and repay it in fixed monthly installments over a set term, typically 5 to 20 years.
The interest rate on a HELOAN is fixed. Your monthly payment doesn't change from the first month to the last. If you borrow $50,000 at 7.00% over 15 years, you'll pay $449 per month every single month until it's paid off.
Because the HELOAN is a second lien on your property, it sits behind your first mortgage. If you default, your first mortgage lender gets paid first. This is the same structure as a HELOC.
The HELOAN is sometimes called a second mortgage for this reason. It is closed-end, meaning once you receive the funds and start repaying, you cannot go back and borrow more from the same loan.
What is a HELOC?
A home equity line of credit, or HELOC, is a revolving credit line secured by your home's equity. It works like a credit card with your house as collateral. You're approved for a maximum credit limit, and you can draw from it, repay it, and draw again during a defined draw period.
The draw period typically lasts 10 years. During this time, most lenders require interest-only payments on the amount you've borrowed. When the draw period ends, you enter the repayment period, usually 10 to 20 years, where you repay both principal and interest on whatever balance remains.
The interest rate on a HELOC is variable. It's typically tied to the prime rate plus a lender margin. In early 2026, the prime rate stands at 6.75%. A lender charging a 0.50% margin would set your HELOC rate at 7.25%. That rate moves when the prime rate moves.
This variable structure means your monthly payment can go up or down over the life of the line. Some lenders offer a fixed-rate conversion option, letting you lock a portion of your outstanding HELOC balance at a fixed rate, but this varies by institution.
How much can you borrow?
Both products use the same underlying calculation. Lenders look at your combined loan-to-value ratio, or CLTV, which adds your existing mortgage balance to the new borrowing and divides the total by your home's appraised value.
Most lenders allow a maximum CLTV of 80% to 85%. A few will go to 90%, but those come with higher rates and stricter credit requirements.
Here's the formula:
If your home is worth $500,000, you owe $300,000 on your mortgage, and your lender allows 85% CLTV:
$425,000 − $300,000 = $125,000 available to borrow
A credit score below 680 will reduce what you can borrow and increase your rate. Most lenders want to see at least 15% to 20% equity remaining after the new borrowing, and a debt-to-income ratio under 43%.
How much could you borrow?
With a home worth $500,000 and $300,000 remaining on your mortgage, you could access up to $125,000 through a HELOC or HELOAN at an 85% CLTV limit.
Estimate. Actual borrowing limits depend on your credit score, income, and lender terms.
Fixed vs. variable: the rate tradeoff
The HELOAN's fixed rate is its defining feature. You know your payment on day one and it never changes. In a rising rate environment, that certainty is worth something. In a falling rate environment, you're locked in unless you refinance.
The HELOC's variable rate cuts the other way. If rates fall, your payment drops automatically. If rates rise, you pay more without doing anything. Over a 10-year draw period, that variable exposure is real.
In early 2026, the average HELOC rate is approximately 7.25% and the average HELOAN rate is approximately 6.96% to 7.56% depending on the lender and term. The gap between the two is modest right now, which makes the fixed-versus-variable question more about risk tolerance than rate arbitrage.
One scenario where the HELOC rate works against you: if you draw a large balance early and rates rise before you pay it down. One scenario where it works for you: if you draw small amounts over time and rates stay flat or fall.
HELOC vs HELOAN: side-by-side
| Feature | HELOAN | HELOC |
|---|---|---|
| Payout structure | Lump sum at closing | Draw as needed, revolving |
| Interest rate type | Fixed | Variable (some fixed options) |
| Payment during draw | N/A — repayment starts immediately | Interest-only on drawn balance |
| Repayment term | 5 to 20 years | 10-year draw, 10 to 20-year repayment |
| Rate predictability | High — payment never changes | Low — payment moves with prime rate |
| Flexibility | Low — can't reborrow | High — draw, repay, redraw |
| Best for | Known, one-time expenses | Ongoing or uncertain expenses |
| Rate environment fit | Better in rising rate environment | Better in falling or flat rate environment |
| Closing costs | Typically 2% to 5% of loan amount | Often lower; some lenders waive entirely |
See the payment difference
After the draw period ends, your HELOC payment will increase to include principal. Your actual repayment payment will depend on your remaining balance at that time.
During the draw period, the HELOC costs $147 less per month — but that payment is interest-only and will reset when repayment begins.
Is the interest tax-deductible?
Sometimes. The 2017 Tax Cuts and Jobs Act changed the rules significantly, and the confusion has never fully cleared up.
The short version: interest on a HELOC or HELOAN is tax-deductible only if you use the funds to buy, build, or substantially improve the home that secures the loan. Using the money to pay off credit card debt, cover a wedding, or fund a business does not qualify, even though your house is the collateral.
You must also itemize your deductions, not take the standard deduction. The standard deduction for married filing jointly is $31,500 in 2025. Most households do not have enough itemized deductions to clear that threshold, which means the mortgage interest deduction, including home equity interest, provides no actual tax benefit even for homeowners who qualify for it in theory.
The deduction also applies only to the first $750,000 of total home loan debt across your primary mortgage and the HELOC or HELOAN combined.
If you're using the funds for home improvement, consult a tax professional before assuming you'll get the deduction. If you're using the funds for anything else, don't count on it.
When to choose a HELOAN
The HELOAN fits specific situations well.
You know exactly how much you need. A roof replacement, a kitchen remodel with a firm contractor bid, a debt consolidation payoff with a specific balance. When the dollar amount is defined upfront, the lump sum structure works cleanly.
You want a fixed payment. If you're on a fixed income, managing a tight budget, or simply want to know your exact payment from day one, the HELOAN's predictability is a real advantage. A HELOC's payment can shift month to month as rates move and as your drawn balance changes.
You want to consolidate high-interest debt. Replacing $40,000 in credit card debt at 22% with a HELOAN at 7% saves approximately $6,000 per year in interest on that balance alone. The risk is that you've converted unsecured debt to debt secured by your home. If you run the cards back up, you've added a second mortgage without eliminating the original problem.
When to choose a HELOC
The HELOC fits a different set of needs.
Your expenses are spread out over time. Home renovation projects where scope expands, education costs billed semester by semester, medical treatment with unknown total cost. The HELOC lets you draw what you need when you need it and pay interest only on what you've used.
You want a financial backstop. A HELOC with a zero balance costs you nothing to maintain in most cases. Some homeowners open one specifically for emergency access, drawing nothing but keeping the line available. Think of it as a very low-cost credit facility secured by your largest asset.
You expect to repay relatively quickly. During the draw period, you can pay down principal aggressively if you choose. If you borrow $30,000 for a renovation and repay $10,000 six months later, you're only paying interest on $20,000. A HELOAN requires you to repay on the original full balance regardless of how the project unfolds.
Not sure? Answer three questions.
Do you know exactly how much money you need?
The risk both products share
Your home is the collateral. If you can't make payments on a HELOAN or HELOC, the lender can foreclose. This is a qualitatively different risk than defaulting on a credit card or personal loan. Defaulting on unsecured debt damages your credit. Defaulting on a HELOC or HELOAN can cost you your home.
This is not a reason to avoid home equity products. It is a reason to borrow only what you have a clear plan to repay, to keep your total debt service within your budget even if rates rise, and to make sure an emergency expense isn't the only reason you're opening a new lien on your primary asset.
The honest take
The HELOAN and HELOC are complementary tools, not competing ones. The right choice depends almost entirely on how you plan to use the money.
If the amount is known, the purpose is defined, and you want a predictable payment, the HELOAN wins. If the expense is ongoing, uncertain, or phase-dependent, or if you want flexible access without necessarily drawing anything, the HELOC wins.
The rate difference between the two is currently small. What matters more is matching the structure to the need.
Either way, you are putting your home on the line. That cuts the rate, but it raises the stakes. Borrow with a plan.
