A HELOC is a revolving loan against your home's equity that you can draw from, repay, and redraw

A HELOC (home equity line of credit) works like a credit card backed by your house. The lender looks at your home's current value, subtracts what you still owe on your mortgage, and lets you borrow against that difference—your equity. You don't get the money all at once. Instead, you get access to a credit line and draw what you need, when you need it. You pay interest only on the amount you've actually borrowed, not the full line.

The lender secures the HELOC with a second mortgage on your home, meaning if you stop paying, they can foreclose. This is why HELOCs typically carry lower interest rates than credit cards or personal loans—the lender's risk is lower because they have a claim on your property.

HELOCs come in two phases: a draw period (usually 5 to 10 years) when you can borrow and repay as needed, and a repayment period (usually 10 to 20 years) when you can no longer draw new money and must pay back what you owe. Your monthly payment and interest rate can change, especially when the draw period ends.

Key Takeaways

  • You only pay interest on money you actually borrow, not on the full credit line available to you.
  • During the draw period, you can borrow, repay, and borrow again; during repayment, you can only pay down the balance.
  • Interest rates on HELOCs are usually variable, meaning your monthly payment can rise or fall as market rates change.
  • Your home serves as collateral, so missing payments can result in foreclosure.
  • Closing costs, annual fees, and early repayment penalties vary by lender and should be compared before you commit.

How the draw period works

During the draw period, you access your HELOC the way you'd use a credit card. You receive a checkbook, debit card, or online access to your account. You draw money when you need it—for a home repair, medical bill, or other expense. The lender deposits the funds into your account, usually within one to three business days.

You're required to make a minimum payment each month, but that minimum often covers only interest, not principal. If you pay only interest during the draw period, your balance doesn't shrink. You can pay more than the minimum to reduce what you owe, and you can redraw that paid-down amount if you need it again—that's what makes it a "line" rather than a one-time loan.

Interest rates on HELOCs are almost always variable, tied to a benchmark rate like the prime rate. When the benchmark moves, your rate moves with it, usually within 30 to 60 days. Your monthly payment can therefore increase or decrease unpredictably. Some lenders offer a fixed-rate option for part or all of the line, but this typically costs more upfront.

What happens when the draw period ends

When your draw period ends—say, after 7 years—the HELOC converts to a repayment-only phase. You can no longer borrow new money. Instead, you must pay back the full balance over the remaining term, usually 10 to 20 years. Your monthly payment jumps significantly because you're now paying both principal and interest, and you're doing it over a fixed number of years.

If you haven't paid down the balance during the draw period, this conversion can be a financial shock. A $50,000 balance that required only $200 monthly interest payments might suddenly require $500 to $700 monthly to pay off over 15 years. Some borrowers refinance into a new HELOC or a home equity loan to avoid this payment spike, but that requires may have access to again and paying new closing costs.

Interest rates and how they change

Most HELOCs use a variable interest rate, which means the rate you pay is not fixed for the life of the loan. The rate is usually calculated as a benchmark (the prime rate, set by the Federal Reserve) plus a margin (a percentage added by your lender). When the Federal Reserve raises or lowers rates, your HELOC rate typically follows within weeks.

During periods of rising rates, your monthly payment can increase substantially. During periods of falling rates, your payment may decrease. This unpredictability makes budgeting harder than with a fixed-rate mortgage or home equity loan. Some lenders offer a fixed-rate option for all or part of your HELOC balance, but you usually pay a higher rate or a one-time fee for that stability.

Your lender can also change the terms of your HELOC. If your home's value drops, your credit score falls, or the economy weakens, the lender may reduce your available credit line or freeze it entirely. During the 2008 financial crisis, many lenders froze HELOCs, leaving borrowers unable to access funds they thought they had.

Costs and fees to compare

HELOCs are not free to open. Closing costs typically range from $0 to $1,500, depending on your lender and location, and may include appraisal fees, title search, attorney fees, and processing costs. Some lenders waive closing costs to attract borrowers, but they may charge higher interest rates or annual fees to compensate.

Annual maintenance fees vary. Some lenders charge $25 to $100 per year just to keep the account open. Others charge only if you don't use the line. Inactivity fees may apply if you don't draw money for a set period. Early repayment penalties are less common with HELOCs than with home equity loans, but some lenders do charge them, so ask before you sign.

Compare the total cost across lenders: closing costs plus the interest rate plus any annual or inactivity fees. A HELOC with no closing costs but a higher rate may cost more over time than one with upfront fees but a lower rate.

Risks of borrowing against your home

A HELOC is secured by your home, which means your house is collateral. If you miss payments, the lender can foreclose and sell your home to recover what you owe. This risk is real and serious—it's why HELOCs carry lower rates than unsecured debt, but it's also why they're riskier for you.

Variable rates create payment uncertainty. If rates rise sharply, your monthly payment could double or triple, straining your budget. If you're already stretched financially, a HELOC can become unmanageable quickly. Borrowers sometimes use HELOCs to pay off credit card debt, which can work if they don't run up the credit cards again—but many do, ending up with both a HELOC and credit card debt.

Falling home values also pose a risk. If your home's value drops below what you owe on your mortgage plus your HELOC, you're underwater. You can't sell without a loss, and refinancing becomes difficult or impossible. This happened to millions of homeowners after 2008.

HELOC vs. home equity loan vs. cash-out refinance

A home equity loan is different from a HELOC. With a home equity loan, you borrow a lump sum upfront and repay it over a fixed term (usually 5 to 15 years) at a fixed rate. Your payment never changes. You can't redraw money. Home equity loans are simpler to budget for but less flexible—you get all the money at once whether you need it or not, and you pay interest on the full amount immediately.

A cash-out refinance replaces your entire mortgage with a new, larger one and gives you the difference in cash. If you owe $200,000 on a home worth $300,000, you might refinance for $250,000 and pocket $50,000. You refinance your entire mortgage, so closing costs are higher, but you get a single payment and potentially a better rate if market rates have dropped. The downside: you restart the clock on your mortgage term, so you may pay interest for 30 years instead of the 20 you had left.

Choose based on your needs. If you need money once for a specific purpose, a home equity loan or cash-out refinance may be clearer. If you need flexible access to funds over time, a HELOC works better. If you want payment certainty, avoid variable-rate HELOCs or choose a fixed-rate option.

Frequently Asked Questions

Can I use a HELOC for anything, or are there restrictions?

Most lenders don't restrict how you use HELOC funds. You can use them for home repairs, medical bills, education, debt consolidation, or other expenses. Some lenders ask what the money is for, but enforcement is rare. The exception: you cannot use a HELOC to purchase another property in most cases, because the lender's security interest is in your primary residence.

What happens to my HELOC if I sell my house?

When you sell, the sale proceeds pay off your mortgage first, then your HELOC balance, then you keep what's left. If the sale price doesn't cover both debts, you must pay the difference out of pocket before closing. Your HELOC is closed at sale; you cannot keep it open on a property you no longer own.

Can I get a HELOC if I have bad credit?

It's harder but possible. Lenders typically want a credit score of 620 or higher and a debt-to-income ratio below 43 percent. If your score is lower, you may find lenders willing to work with you, but they'll charge a higher interest rate. Having significant equity in your home helps, because it reduces the lender's risk.

What if interest rates spike during my draw period?

Your monthly payment will increase. If you're paying interest-only, your payment rises. If you're paying principal and interest, your payment rises even more. Some lenders cap how much your rate can increase per year or over the life of the loan—ask about rate caps before you sign. Without caps, your rate can theoretically rise without limit.

Can I pay off my HELOC early without a penalty?

Most HELOCs allow early repayment without penalty, but some lenders charge a fee if you close the account within a certain period (often 3 to 5 years). Read the terms carefully. Paying off early saves you interest, but if you have an annual fee, you'll still owe it for each year you hold the account open.
