A HELOC lets you borrow against the equity you've built in your home, and you pay interest only on the money you actually use

A HELOC (home equity line of credit) works like a credit card backed by your house. Your lender looks at your home's current value, subtracts what you still owe on your mortgage, and lets you borrow up to a percentage of that difference — typically 80 to 90 percent of your equity. You don't have to take all that money at once. Instead, you get access to a credit line and draw from it when you need it, paying interest only on what you've borrowed.

The lender secures the HELOC with a second mortgage on your home, which means if you stop paying, they can foreclose just like your primary lender can. That's why HELOCs usually come with lower interest rates than credit cards or personal loans — the lender's risk is lower because your house backs the debt.

Key Takeaways

  • A HELOC gives you a credit line based on your home's equity, and you pay interest only on money you actually withdraw.
  • Most HELOCs have a draw period (usually 5 to 10 years) when you can borrow, followed by a repayment period when you can no longer draw and must pay back what you owe.
  • Interest rates on HELOCs are almost always variable, meaning your monthly payment can go up or down as market rates change.
  • Your home secures the debt, so defaulting on a HELOC can result in foreclosure, just as with your primary mortgage.
  • You need significant equity in your home to open a HELOC, and most lenders require you to have paid down your mortgage to at least 80 percent of the home's value.

The Draw Period and Repayment Period

A HELOC has two phases. During the draw period — typically 5 to 10 years — you can borrow money whenever you want, up to your credit limit. You can pay it back, borrow again, and repeat. Many people pay only interest during this phase, which keeps their monthly payment low. Some lenders require minimum payments that include a bit of principal, but the terms vary.

Once the draw period ends, the repayment period begins, usually lasting 10 to 20 years. Now you can no longer borrow. You must pay back everything you've borrowed, plus interest, on a fixed schedule. Your payment jumps significantly because you're now paying down principal, not just interest. This shock is one reason HELOCs surprise homeowners — the low payment during the draw period masks what's coming.

Some HELOCs convert to a fixed-rate loan at the end of the draw period. Others require a lump-sum payment or refinancing. Read the terms carefully, because what happens at the end of the draw period is your responsibility to manage.

Variable Interest Rates and Payment Changes

Nearly all HELOCs have variable interest rates, tied to a market index like the prime rate. When the Federal Reserve raises rates, your HELOC rate rises too, usually within one or two billing cycles. When rates fall, your rate falls. This means your monthly payment can change several times a year.

During the draw period, a rate increase might only affect the interest you're paying on borrowed money — manageable if you're only drawing small amounts. But when you enter the repayment period and your payment includes principal, a rate jump can make your monthly bill jump hundreds of dollars. If rates have risen significantly since you opened the HELOC, you could face a payment you can't afford.

Some HELOCs include a rate cap — a maximum rate you'll never exceed — but not all do. Ask about caps before you sign. A cap protects you from the worst-case scenario, but it also means the lender may charge a higher starting rate to offset that protection.

What You Need to may have access to for a HELOC

Lenders want to see that you have real equity in your home and a reliable income to service the debt. Most require you to have at least 15 to 20 percent equity remaining after the HELOC is opened — meaning your total debt (mortgage plus HELOC) can't exceed 80 to 85 percent of your home's value. If your home is worth $300,000 and you owe $200,000 on your mortgage, you have $100,000 in equity, and a lender might let you borrow $60,000 to $80,000 on a HELOC.

You'll also need a decent credit score — typically 650 or higher, though 700+ gets you better rates — and proof of income. Lenders pull your credit report, order an appraisal of your home, and verify your employment and income, much like they do for a mortgage. The process usually takes 2 to 4 weeks.

Your debt-to-income ratio matters too. If you already carry a lot of debt relative to your income, a lender may deny you or offer a smaller credit line. They're checking whether you can handle the HELOC payment on top of your existing obligations.

When a HELOC Makes Sense

A HELOC works well for planned, medium-term expenses where you know roughly how much you'll need and when. Home renovations, education costs, or paying off high-interest debt are common uses. Because you draw only what you need, you pay interest only on that amount, and the interest is often tax-deductible if you use the money for home improvements.

A HELOC is less suitable if you're not disciplined about borrowing. The ease of access can tempt you to borrow for things you don't really need, and suddenly you're entering the repayment period with a large balance and a payment you didn't plan for. It's also risky if your income is unstable or if you're near retirement — a payment jump during the repayment period could strain your budget.

If you're borrowing for an emergency or you're unsure how much you'll need, a home equity loan (a lump sum at a fixed rate) might be safer. You get the money upfront, you know exactly what your payment will be for the life of the loan, and there's no surprise when the draw period ends.

Fees and Closing Costs

Opening a HELOC costs money. Expect to pay an appraisal fee ($300 to $700), a credit report fee, title search and insurance, and possibly an origination fee. Total closing costs typically run $1,000 to $3,000, though some lenders waive fees to attract borrowers. Ask upfront whether fees are waived and get a Loan Estimate in writing so you know the total before you commit.

Some HELOCs also charge an annual fee just to keep the line open, even if you don't borrow. Others charge a fee if you don't use the line for a certain period. Read the fine print. These fees are small — often $25 to $100 per year — but they add up if you open a HELOC and then don't use it.

The Risk of Losing Your Home

This is the critical point: a HELOC is secured by your home. If you can't pay, the lender can foreclose and sell your house to recover what you owe. This is different from credit card debt, which is unsecured — a credit card company can sue you and garnish your wages, but they can't take your home.

Foreclosure is a slow process in most states, taking months or even years, but the end result is the loss of your house. If you're considering a HELOC, be honest about whether you can handle the repayment period payment, not just the draw period payment. A rate increase or job loss during the repayment phase could put you in a position where you can't pay.

Never borrow more than you need or can realistically repay. The fact that a lender will let you borrow $100,000 doesn't mean you should.

Frequently Asked Questions

Can I use a HELOC for anything I want?

Yes, legally you can use HELOC money for any purpose — a vacation, a car, debt payoff, or home improvements. However, if you use it for home improvements, the interest may be tax-deductible. For other uses, it's not. Also, using a HELOC for discretionary spending increases the risk that you'll struggle to repay during the repayment period.

What happens if interest rates rise a lot during my draw period?

Your interest rate will rise with the market, and your monthly payment will increase. If you're only paying interest during the draw period, the increase affects only the interest portion. But if you're paying principal too, your payment jumps more. When the repayment period starts, a higher rate means a higher payment for the entire repayment term.

Can I close a HELOC early?

Yes, you can pay off a HELOC at any time without penalty (though check your agreement — some older HELOCs had prepayment penalties). Paying it off early saves you interest and eliminates the risk of a payment shock when the repayment period begins. However, once you close it, you can't borrow from it again.

What's the difference between a HELOC and a home equity loan?

A home equity loan is a lump sum at a fixed rate and fixed payment, paid back over a set term. A HELOC is a credit line with a variable rate, a draw period, and a repayment period. A home equity loan is simpler and more predictable; a HELOC is more flexible but riskier if rates rise or you overborrow.

Do I need to use my HELOC to keep it open?

Not necessarily, but some lenders charge an annual fee or close the line if you don't use it for a certain period (often 12 months). Ask your lender about inactivity policies before you open the HELOC. If you think you might not use it right away, confirm that you won't be charged for keeping it available.
