A HELOC is a line of credit, not a traditional mortgage

A HELOC (home equity line of credit) lets you borrow against the value you have built up in your home, but it works differently than a mortgage. With a mortgage, you borrow a fixed amount upfront and pay it back over a set term. With a HELOC, the lender gives you access to a credit line — similar to a credit card — that you can draw from, repay, and draw from again during an open period.

The key difference: you only pay interest on the money you actually use, not on the full credit line. If your lender approves you for a $100,000 HELOC but you only borrow $30,000, you pay interest only on that $30,000. This makes a HELOC cheaper than a traditional loan if you do not need all the money at once.

Most HELOCs have two phases. During the draw period — typically 5 to 10 years — you can borrow and repay as needed. After that, the repayment period begins, usually lasting 10 to 20 years, and you can no longer borrow. You must pay back whatever balance remains.

Key Takeaways

  • A HELOC is a revolving credit line secured by your home's equity, not a lump-sum loan like a traditional mortgage.
  • You pay interest only on the amount you borrow, making it less expensive than a personal loan if you need money gradually.
  • The draw period lets you borrow freely; the repayment period forces you to pay back the balance without borrowing more.
  • Interest rates on HELOCs are usually variable, meaning your monthly payment can rise if rates increase.
  • Your home serves as collateral, so failure to repay can result in foreclosure.

How the interest rate and payments work

Most HELOCs use a variable interest rate tied to a market index like the prime rate. This means your rate — and your monthly payment — can change over time. If the prime rate goes up, so does your HELOC rate. If it falls, your rate falls too. Lenders typically add a margin (usually 1% to 3%) on top of the index rate.

During the draw period, many lenders let you pay interest-only, which keeps your monthly payment low. Once the repayment period starts, you must pay both principal and interest, and your payment jumps significantly. This is a real cost to plan for: a $50,000 HELOC borrowed at 7% might cost $290 per month during interest-only years, but $580 or more per month during repayment.

Some lenders offer fixed-rate HELOCs or let you lock in a fixed rate on part of your balance. These cost more upfront but protect you from payment shock if rates rise. Compare the initial rate, the margin, and what happens when the draw period ends before you commit.

What you need to may have access to for a HELOC

Lenders look at three main things: how much equity you have, your credit score, and your income. You typically need at least 15% to 20% equity in your home — meaning you owe no more than 80% to 85% of what it is worth. If your home is worth $300,000 and you owe $200,000, you have $100,000 in equity and likely may have access to.

Your credit score matters more for a HELOC than for a mortgage because you are borrowing against existing equity. Most lenders want a score of 620 or higher, though better rates go to borrowers with scores above 700. You will also need to show stable income and a debt-to-income ratio (total monthly debt payments divided by gross monthly income) below 43% to 50%, depending on the lender.

The lender will order an appraisal to confirm your home's current value. This costs $300 to $500 and comes out of your pocket, though some lenders credit it back if you close. You will also pay closing costs — typically 2% to 5% of the credit line amount — for title search, underwriting, and legal fees.

When a HELOC makes sense versus other borrowing options

A HELOC works well if you need money over time for a project with staggered costs — a home renovation, medical bills spread across months, or a business startup. You draw only what you need and when you need it, keeping interest costs down. It also works if you want a backup emergency fund at a lower rate than a credit card.

A HELOC is usually cheaper than a personal loan or credit card because your home secures it and rates are lower. However, it is riskier: if you cannot repay, the lender can foreclose. A personal loan or credit card does not put your home at risk, though the interest rate is much higher.

If you need a large sum right now — to pay off debt, buy a car, or fund a full renovation — a cash-out refinance (borrowing against your equity by refinancing your mortgage) might be simpler. You get one lump sum and one payment instead of managing a credit line. The trade-off is that you refinance your entire mortgage, which resets your loan term and may cost more in total interest.

The risks of borrowing against your home

The biggest risk is that your home is collateral. If you miss payments, the lender can foreclose and take your house. This is not a threat with a credit card or personal loan. Before opening a HELOC, make sure you can afford the payments, especially once the repayment period begins and your payment rises.

Variable rates create payment uncertainty. If rates climb 2% or 3%, your monthly payment could double or triple. Some HELOCs have rate caps — a maximum rate you will ever pay — but not all. Read the fine print and stress-test your budget: can you afford the payment if rates hit the cap?

Borrowing against your home also reduces the equity cushion you have built. If your home value drops and you owe more than it is worth, you are underwater. This limits your ability to refinance, sell, or borrow again. Only borrow what you truly need and have a plan to repay it.

HELOC versus a home equity loan

A home equity loan is similar to a HELOC but works like a traditional mortgage: you borrow a fixed amount upfront, receive it as a lump sum, and repay it over a set term with a fixed or variable rate. You cannot borrow more once you close the loan.

Choose a home equity loan if you need all the money at once and want predictable payments. Choose a HELOC if you need money gradually, want flexibility to borrow and repay multiple times, or want to keep a safety net available. HELOCs typically have lower initial rates but variable payments; home equity loans have higher rates but stable payments.

Closing costs and fees to expect

HELOC closing costs typically range from 2% to 5% of the credit line amount. A $100,000 HELOC might cost $2,000 to $5,000 in fees. These include the appraisal ($300–$500), title search and insurance ($200–$400), underwriting and processing ($300–$500), attorney fees ($200–$400), and lender fees ($500–$1,500). Some lenders waive or reduce these fees to compete for your business.

You may also face annual maintenance fees ($25–$100) or inactivity fees if you do not use the line for a period. Some lenders charge a fee if you close the account early. Ask about all fees upfront and factor them into your decision. A HELOC with lower rates but high fees may cost more than one with slightly higher rates and no fees.

Frequently Asked Questions

Can I use a HELOC for anything I want?

Yes. Lenders do not restrict how you use HELOC funds. People use them for home repairs, debt consolidation, education, medical bills, business expenses, and vacations. However, using a HELOC to fund high-risk ventures or poor financial decisions puts your home at risk, so borrow only for purposes you can afford to repay.

What happens to my HELOC if my home value drops?

Your lender may freeze or reduce your credit line if your home's value falls significantly. This happened to many homeowners during the 2008 housing crisis. Some lenders also have the right to demand immediate repayment if your equity drops below a certain threshold, though this is rare. Check your agreement for these terms.

Can I pay off my HELOC early?

Yes, and most lenders do not charge a prepayment penalty. Paying early saves you interest and reduces the shock when the repayment period begins. However, read your agreement to confirm there is no penalty. Some lenders also allow you to extend the draw period or convert your balance to a fixed rate if you ask.

Is a HELOC a good way to pay off credit card debt?

A HELOC usually has a lower interest rate than credit cards, so it can save money. However, it puts your home at risk if you cannot repay. Only use a HELOC for debt consolidation if you have a solid plan to avoid running up credit card balances again. Otherwise, you end up with both HELOC and credit card debt.

What is the difference between a HELOC and a home equity loan?

A HELOC is a revolving credit line you draw from as needed; a home equity loan is a lump-sum loan with fixed payments. HELOCs offer flexibility and lower initial rates but variable payments. Home equity loans offer predictability but higher rates and less flexibility. Choose based on whether you need money gradually or all at once.
