A HELOC is a line of credit you borrow against, not a lump sum you receive upfront

A HELOC (Home Equity Line of Credit) works like a credit card attached to your house. The lender gives you access to a pool of money based on how much equity you have built up in your home. You draw from that pool when you need it, pay interest only on what you actually borrow, and can borrow again as you pay it back — all during a set time period called the draw period.

The key difference from a home equity loan is timing and flexibility. A home equity loan hands you all the money at once. A HELOC lets you take money out in chunks, whenever you want, up to your credit limit. You control when and how much you use.

Your lender sets the credit limit based on your home's current value, how much you still owe on your mortgage, and your credit history. If your home is worth $300,000 and you owe $200,000 on your mortgage, you have $100,000 in equity. The lender might offer you a HELOC for 80 percent of that equity — roughly $80,000 — but the exact amount varies by lender and your financial profile.

Key Takeaways

  • A HELOC gives you a credit limit based on your home equity, and you draw money as needed rather than receiving it all at once.
  • During the draw period (usually 5 to 10 years), you pay interest only on the money you have actually borrowed.
  • After the draw period ends, the repayment period begins and you must pay back the full balance, usually over 10 to 20 years.
  • Interest rates on HELOCs are typically variable, meaning your monthly payment can change if the market rate changes.
  • Your home serves as collateral, so failing to repay puts your house at risk of foreclosure.

How the draw period works and what you pay during it

The draw period is the window of time when you can borrow money from your HELOC. This period typically lasts 5 to 10 years, though the exact length depends on your lender's terms. During the draw period, you can withdraw money as often as you want, up to your credit limit. Some lenders let you write checks, use a debit card, or transfer money online. Others require you to call or visit a branch.

While you are in the draw period, you only pay interest on the balance you have actually drawn. If your credit limit is $50,000 but you have only borrowed $15,000, you pay interest on $15,000. As you pay that $15,000 back, your available credit goes back up, and you can borrow again if you need to.

Monthly payments during the draw period are usually much lower than they will be later, because you are only paying interest on what you have used. Some lenders let you pay interest-only during this phase. Others require you to pay some principal as well. The terms vary, so check your loan documents or ask your lender what your payment structure will be.

What happens when the draw period ends

When the draw period ends, you enter the repayment period. At this point, you can no longer borrow new money from the HELOC. You must begin paying back the full balance you owe, including both principal and interest.

The repayment period typically lasts 10 to 20 years. Your monthly payment will jump significantly because you are now paying down the principal, not just interest. If you borrowed $40,000 during the draw period and paid back $10,000 of it, you now owe $30,000, and that $30,000 must be repaid over the repayment period.

Some borrowers are surprised by how much their payment increases when the draw period ends. Planning for this jump is important. If you cannot afford the higher payment when the repayment period starts, you may face financial hardship or be forced to refinance.

Interest rates and how they affect your payment

Most HELOCs have variable interest rates, meaning the rate changes over time based on market conditions. Your rate is usually tied to a benchmark rate — often the prime rate — plus a margin the lender adds. When the benchmark rate goes up, your interest rate goes up. When it goes down, your rate goes down.

A variable rate can work in your favor if rates fall, but it creates risk if rates rise. Your monthly payment can increase even if you do not borrow any additional money. Some HELOCs offer a fixed-rate option for part or all of the balance, which locks in your rate for that portion. This costs more upfront but removes the uncertainty.

The starting rate on a HELOC is often lower than the rate on a home equity loan or a mortgage refinance, which is one reason people choose them. However, that rate can adjust after an initial period — sometimes after six months, sometimes after a year. Read your loan agreement to see when your rate can first change and how often it can change after that.

Fees and costs to understand before you borrow

HELOCs often come with upfront costs. Common fees include an process fee, an appraisal fee (the lender needs to know your home's current value), and a title search fee. Some lenders charge an annual fee just to keep the line of credit open, whether you use it or not. Others charge a fee if you close the account early.

These costs vary widely by lender. Some lenders waive certain fees to attract borrowers. Others bundle them into the loan. Ask your lender for a complete list of all fees before you commit. The Truth in Lending Act requires lenders to give you a disclosure document that lists these costs, so request it and read it carefully.

You should also understand what happens if you miss a payment. Most HELOCs allow the lender to freeze your credit line and demand when ready repayment of the full balance if you default. Since your home is collateral, the lender can foreclose if you do not pay.

How a HELOC differs from a home equity loan

A home equity loan gives you a fixed amount of money upfront in one lump sum. You receive it all at once, and you begin repaying it when ready on a fixed schedule. The interest rate is usually fixed, so your payment stays the same every month.

A HELOC, by contrast, gives you access to a credit line. You draw money as you need it, pay interest only on what you use, and your payment can change if the rate changes. A home equity loan is simpler if you know exactly how much money you need right now. A HELOC is more flexible if you need money over time or are not sure how much you will need.

Both are secured by your home, meaning your house is at risk if you do not repay. Both allow you to borrow larger amounts than an unsecured personal loan would. The choice between them depends on your situation and how you plan to use the money.

What happens if you cannot repay

If you fall behind on HELOC payments, the lender can freeze your credit line, preventing you from borrowing any more money. They can also demand that you repay the entire balance when ready. If you still do not pay, the lender can begin foreclosure proceedings and take your home.

Because your home is collateral, a HELOC is riskier than an unsecured loan. Before you open a HELOC, make sure you can afford the payments, especially when the draw period ends and your payment increases. If your financial situation changes, contact your lender as soon as possible to discuss your options. Some lenders will work with you on a modified payment plan.

Frequently Asked Questions

Can I have a HELOC and a mortgage at the same time?

Yes. A HELOC is a second lien on your home, meaning it sits behind your mortgage in priority. If you default, the mortgage lender gets paid first from the sale of your home. You can have both, but your total debt against the home cannot exceed what most lenders will allow — typically 80 to 90 percent of your home's value.

What if interest rates rise while I am in the draw period?

Your interest rate will rise with the market, and your monthly payment will increase. If you have a variable-rate HELOC, you have no protection against rate increases unless you locked in a fixed rate for part of your balance. This is why some borrowers convert to a fixed rate or pay down their balance before rates climb too high.

Can I pay off my HELOC early?

Yes, most HELOCs allow early repayment without penalty. However, some lenders charge a prepayment fee, so check your loan documents. Paying off early saves you interest and reduces your risk, since you will owe less when the repayment period begins.

What if I do not use my HELOC at all?

If you never borrow from your HELOC, you typically pay no interest. However, you may still owe an annual fee to keep the line open. Some lenders waive this fee if you maintain a minimum balance or meet other conditions. Check your agreement to see what fees explore even if you do not borrow.

How is a HELOC different from a cash-out refinance?

A cash-out refinance replaces your entire mortgage with a new, larger one and gives you the difference in cash. A HELOC is a separate line of credit on top of your mortgage. A refinance locks in a new rate for your whole mortgage; a HELOC typically has a variable rate. Choose based on whether you want one payment or two, and whether you want a fixed or variable rate.
