A HELOC is a line of credit secured by your home's value
HELOC stands for Home Equity Line of Credit. It is a loan where the lender gives you access to money based on how much your home is worth minus what you still owe on your mortgage. You can borrow, repay, and borrow again during a set period — usually 5 to 10 years — without reapplying each time.
The lender uses your home as collateral, which means if you stop making payments, the lender can foreclose and take the house. Because your home backs the loan, HELOCs typically have lower interest rates than credit cards or personal loans. The interest rate is usually variable, meaning it changes with market conditions.
A HELOC is different from a home equity loan, which gives you a lump sum upfront and requires fixed monthly payments. With a HELOC, you draw money only when you need it, and you pay interest only on what you have borrowed.
Key Takeaways
- A HELOC lets you borrow against your home's equity and access the money on your schedule, not all at once.
- Your home secures the debt, so the lender can foreclose if you default, but this also means lower interest rates than unsecured loans.
- Interest rates on HELOCs are usually variable and tied to market rates, so your monthly payment can go up or down.
- Most HELOCs have a draw period (when you can borrow) followed by a repayment period (when you can only pay back what you owe).
- You need equity in your home to open a HELOC, which means your home's value must exceed what you owe on your mortgage.
How much you can borrow depends on your home's equity
Lenders calculate how much you can borrow by looking at your home's current market value and subtracting what you still owe on your mortgage. That difference is your equity. Most lenders will let you borrow 80 to 90 percent of your total equity, though some go higher or lower depending on their policies and your credit history.
For example, if your home is worth $300,000 and you owe $200,000 on your mortgage, you have $100,000 in equity. A lender offering 80 percent of equity would let you borrow up to $80,000 through a HELOC. If you already have a home equity loan, the lender subtracts that balance from the available amount.
Your credit score, income, and debt-to-income ratio also affect how much you can borrow and what interest rate you receive. Lenders want to see that you can afford the payments and have a history of paying debts on time.
The draw period and repayment period work differently
Most HELOCs have two phases. During the draw period — typically 5 to 10 years — you can borrow money whenever you want, up to your credit limit. You write checks, use a debit card, or transfer money online. During this time, you usually pay only the interest on what you have borrowed, not the principal.
After the draw period ends, the repayment period begins, usually lasting 10 to 20 years. You can no longer borrow new money. Instead, you must repay the full balance you owe, including both principal and interest. Your monthly payment rises significantly because you are now paying back the actual debt, not just interest.
Some HELOCs require you to pay down the balance during the draw period as well. Read the terms carefully, because the transition from draw to repayment can be a financial shock if you are not prepared for the higher payment.
Interest rates on HELOCs are usually variable
Most HELOCs have a variable interest rate tied to a market index, such as the prime rate. When the prime rate goes up, your rate goes up. When it goes down, your rate goes down. This means your monthly payment can change, sometimes significantly, depending on what happens in the broader economy.
Some lenders offer a fixed-rate option for part or all of the HELOC, but this usually comes with a higher starting rate or additional fees. A fixed rate protects you from payment surprises, but you pay more upfront for that protection.
The rate you receive depends on your credit score, the amount you borrow, and current market conditions. Someone with excellent credit might receive a rate 1 to 2 percentage points lower than someone with fair credit.
What you can use a HELOC for varies by lender
Most lenders let you use HELOC money for almost anything — home repairs, debt consolidation, education, medical bills, or starting a business. Some lenders restrict use to home-related expenses, so ask before you open the account if you have a specific purpose in mind.
Using a HELOC to pay off high-interest credit card debt can lower your overall interest costs, but it moves unsecured debt onto your home. If you cannot repay, you risk losing your house. Using it for home improvements can increase your home's value, which may offset the cost of borrowing.
Keep in mind that the money you borrow through a HELOC is a debt you must repay. It is not assistance programs, even though you only pay interest during the draw period.
Risks of a HELOC include payment shock and foreclosure
The biggest risk is payment shock when the draw period ends. If you borrowed $50,000 and paid only interest for 10 years, your monthly payment might jump from $200 to $500 or more when repayment begins. If your income has not increased or your financial situation has changed, this can be unaffordable.
A second risk is that your interest rate can rise during the draw period, increasing your monthly payments even before repayment starts. If rates climb sharply, you might struggle to pay even the interest-only portion. The most serious risk is foreclosure. Because your home secures the HELOC, missing payments gives the lender the right to foreclose. This is different from credit card debt, where the worst outcome is damage to your credit score. With a HELOC, you can lose your home.
If your home's value drops significantly, you might owe more than the house is worth, a situation called being underwater. This limits your options if you need to sell or refinance.
How a HELOC differs from other borrowing options
A HELOC works differently than other types of loans because you draw money as needed rather than receiving it all upfront. Home equity loans give you a lump sum and require fixed payments, while credit cards offer ongoing access but at much higher interest rates. Personal loans do not require collateral but also carry higher rates than HELOCs.
| Type of Loan | How Money Comes to You | Interest Rate | What Secures It |
|---|---|---|---|
| HELOC | Borrow as needed during draw period | Usually variable | Your home |
| Home Equity Loan | Lump sum upfront | Usually fixed | Your home |
| Credit Card | Borrow as needed, ongoing | Variable, usually high | Nothing (unsecured) |
| Personal Loan | Lump sum upfront | Fixed or variable | Nothing (unsecured) |
A HELOC is most useful if you need access to money over time but do not know the exact amount upfront. A home equity loan works better if you need a specific sum all at once. The choice depends on whether you value flexibility in borrowing or predictability in payments.
Frequently Asked Questions
Can I lose my house if I do not pay a HELOC?
Yes. Because your home secures the HELOC, the lender can foreclose if you fall behind on payments. This is the main difference between a HELOC and unsecured debt like credit cards. Missing payments on a credit card damages your credit but does not put your home at risk.
What happens to my HELOC if interest rates rise?
Your interest rate and monthly payment will likely increase if you have a variable-rate HELOC and market rates go up. Some HELOCs have a rate cap that limits how high the rate can climb, but not all do. Check your terms to see if there is a cap and what it is.
Do I have to use the full credit limit on a HELOC?
No. You borrow only what you need and pay interest only on what you have borrowed. If your credit limit is $80,000 but you only draw $20,000, you pay interest on $20,000. You can leave the rest unused and access it later if needed.
What is the difference between a HELOC and a home equity loan?
A home equity loan gives you all the money upfront in one payment and requires fixed monthly payments. A HELOC lets you borrow as needed during the draw period and usually has lower payments during that time. Home equity loans typically have fixed rates; HELOCs usually have variable rates.
Can I get a HELOC if I have bad credit?
It is harder but sometimes possible. Lenders are more willing to work with lower credit scores on HELOCs than on unsecured loans because your home backs the debt. However, you will likely receive a higher interest rate and may be able to borrow less. Shop around with multiple lenders.
