HELOC vs Home Equity Loan: Full Comparison

If you've built up significant equity in your home, you've got access to some of the cheapest borrowing around. Home equity products typically offer rates way lower than credit cards or personal loans because your home is the collateral. But picking the wrong type of equity financing — or using it for the wrong purpose — can put your most valuable asset on the line. This guide breaks down the three main ways to tap your home equity and helps you figure out which one fits.

What Is Home Equity?

Home equity is the portion of your home you actually own. It's your home's current market value minus what you still owe on the mortgage. If your home is worth $450,000 and you owe $280,000, you have $170,000 in equity.

Most lenders let you borrow against 80% to 85% of your home's value, minus your existing mortgage. Using the example above, at 85% loan-to-value, your maximum combined borrowing would be $382,500. Subtract the $280,000 mortgage, and you have $102,500 available to borrow through a home equity product.

The Three Ways to Access Home Equity

How a HELOC Works

A Home Equity Line of Credit (HELOC) works a lot like a credit card secured by your home. The lender approves you for a maximum credit limit, and you can borrow against that limit during an initial draw period, which typically lasts 5 to 10 years.

During the draw period, you generally make interest-only payments on what you've actually borrowed — not on the full credit limit. Some HELOCs require small principal payments too, but they're still much lower than what you'll pay during the repayment phase.

After the draw period ends, the repayment period kicks in — usually 10 to 20 years. You can no longer draw funds and must repay both principal and interest. Monthly payments can jump substantially, sometimes doubling or tripling, because you're now amortizing the full balance over the remaining term.

Variable Interest Rates

Most HELOCs come with a variable rate tied to a benchmark index, most commonly the Prime Rate or the Secured Overnight Financing Rate (SOFR). Your rate is the index plus a margin. For example, if the Prime Rate is 8.0% and your margin is 0.5%, your HELOC rate is 8.5%.

That means your rate can change over time. Many HELOCs include a lifetime rate cap, but even with caps, your payments can swing significantly if rates rise. Some lenders offer a fixed-rate conversion option that lets you lock in a portion of your balance at a fixed rate — handy if rates are climbing.

Tip: Before taking a HELOC, model worst-case payment scenarios using the maximum possible rate. If you can't afford payments at the rate cap, you're taking on more risk than you can handle. Use our HELOC Calculator to explore different rate environments.

How a Home Equity Loan (HELOAN) Works

A Home Equity Loan, sometimes called a second mortgage, gives you a lump sum at a fixed interest rate. You get the full amount at closing and start repaying right away with predictable monthly payments over a set term — typically 5 to 30 years.

The fixed rate is the big advantage over a HELOC. You know exactly what your payment will be for the entire life of the loan, which makes budgeting simple and eliminates the risk of rising rates. The trade-off is that you get all the money at once, so you pay interest on the full amount from day one — even if you don't need it all right away.

HELOAN rates are typically higher than primary mortgage rates but lower than personal loan or credit card rates. The exact rate depends on your credit score, loan-to-value ratio, and how much you're borrowing.

How Cash-Out Refinancing Works

A cash-out refinance replaces your existing mortgage with a larger one, and you get the difference in cash. If your home is worth $450,000, you owe $280,000, and you refinance at 80% LTV, your new mortgage would be $360,000. After paying off the old $280,000 mortgage, you walk away with $80,000 in cash.

The main advantage is that the cash portion borrows at your primary mortgage rate — usually the lowest rate available for any type of borrowing. The downside is that you're resetting your mortgage, which means starting the amortization schedule over and potentially paying more total interest in the long run.

Tax Deductibility

Under current U.S. tax law (post-2017 Tax Cuts and Jobs Act), interest on home equity borrowing is deductible only if you use the funds to substantially improve your home. This applies to HELOCs, HELOANs, and cash-out refinances alike.

• Deductible: Using a HELOC to fund a kitchen renovation, add a bathroom, or replace a roof
• Not deductible: Using a HELOC to pay off credit cards, fund a vacation, or cover tuition

The deduction is limited to interest on the first $750,000 of qualified residence loans ($375,000 if married filing separately). There's an exception: if you use home equity proceeds for home improvements, the interest counts toward this limit even if your total mortgages exceed the cap, because the improvement-related debt is treated as acquisition indebtedness.

Note: Tax law is complicated and changes often. Always talk to a qualified tax professional before making financial decisions based on potential deductions.

Risks: Understanding the Foreclosure Danger

This is the most important section of this guide. Both HELOCs and HELOANs are secured by your home. If you miss payments, the lender can foreclose — just like your primary mortgage lender can. Your home is the collateral, and it doesn't matter whether it's a "first" or "second" mortgage when it comes to the risk of losing the home.

A few things make home equity borrowing especially risky:

1. Declining home values — If your home drops in value, you could end up "underwater," meaning you owe more than the home is worth. That makes it tough to sell or refinance.

2. HELOC payment shock — The jump from interest-only payments during the draw period to full principal-and-interest payments during repayment can catch people off guard. If you borrowed the full amount during the draw period, your payment could increase by several hundred dollars a month.

3. Balloon payments — Some HELOANs have balloon payments where a large lump sum comes due at the end of the term. If you can't refinance or pay the balloon, you risk foreclosure.

4. Lender can freeze or reduce your credit line — Under federal law, lenders can freeze or cut your HELOC credit limit if your home's value drops significantly, your finances deteriorate, or you miss payments.

Best Uses for Each Product

When to choose a HELOC:

• Home renovation projects where costs unfold over time and the total isn't certain
• Ongoing expenses like tuition payments spread across several semesters
• Emergency reserves where you want access to funds but may not end up needing them
• Real estate investing where you need flexible, staged financing

When to choose a Home Equity Loan:

• A single large expense like a major renovation, medical bills, or debt consolidation where you know the exact amount you need
• When payment predictability matters — you're on a fixed income or have a tight budget
• Debt consolidation — swapping high-interest credit card debt for a lower, fixed-rate payment

When to choose a Cash-Out Refinance:

• Current mortgage rates are significantly lower than your existing rate, so you can lower your rate and pull out cash
• You want to simplify by having one monthly payment instead of a first mortgage plus a HELOC or HELOAN
• You need a large amount of cash and want the lowest possible interest rate

Making the Right Choice

The decision between a HELOC, HELOAN, and cash-out refinance comes down to a few things: how much you need, when you need it, whether you can handle payment swings, and what the money's for. Start by figuring out your total borrowing capacity, then compare the total cost of each option — including closing costs, interest rates, and tax implications — over the time you expect to carry the debt.

The right choice is the one that gets you the funds you need at the lowest total cost, with a repayment structure you can comfortably manage — without putting your home at unnecessary risk.
