A HELOC is a revolving loan against your home's equity that you can borrow from, repay, and borrow from again
A HELOC (home equity line of credit) works like a credit card, except the credit limit is based on how much equity you have built up in your home. You borrow money when you need it, pay interest only on what you actually use, and can draw from it again once you repay. The lender holds a second mortgage on your house as security — meaning if you stop paying, the lender can foreclose.
The process has two phases: a draw period (usually 5 to 10 years) when you can borrow and make minimum payments, and a repayment period (usually 10 to 20 years) when you can no longer borrow and must pay back what you owe in full. Your interest rate is almost always variable, meaning it moves up and down with the market — unlike a fixed-rate home equity loan or mortgage.
Key Takeaways
- You only pay interest on the money you actually draw, not on your full credit limit, which makes a HELOC cheaper than a personal loan if you borrow slowly.
- The draw period lets you borrow whenever you want, but the repayment period forces you to pay back everything within a set timeframe, which can mean a sharp payment increase.
- Your interest rate changes with market conditions, so your monthly payment is not locked in and can rise significantly if rates climb.
- The lender can freeze or close your HELOC if your home value drops, your credit score falls, or the economy weakens — you are not may provide access to the full credit line.
- Missing payments puts your home at risk because the HELOC is secured by a second mortgage on your property.
How the draw period works and what you actually pay
During the draw period, you can write checks, use a debit card, or request transfers from your HELOC account whenever you need money. You are not required to borrow the full amount — you only pay interest on what you use. If your credit limit is $50,000 but you only draw $10,000, you pay interest on $10,000.
Most lenders require you to make a minimum payment during the draw period, but that payment often covers interest only and does not reduce your principal balance. This means if you borrow $10,000 and make only the minimum payment for five years, you still owe $10,000 at the end of the draw period. When the repayment period begins, your payment jumps because you now have to pay back the full amount plus interest over the remaining years.
The length of the draw period varies by lender — some offer 5 years, others 10 years. A longer draw period gives you more time to borrow gradually and keep payments low, but it also means a steeper payment shock when repayment begins.
Variable interest rates and payment changes
Almost all HELOCs have variable interest rates tied to a market index, usually the prime rate. When the Federal Reserve raises rates, your HELOC rate rises within weeks or months. When rates fall, your rate falls. This is different from a fixed-rate mortgage or home equity loan, where your rate never changes.
Your rate is typically the index plus a margin set by the lender — for example, prime rate plus 1.5 percent. If the prime rate is 7 percent, your rate is 8.5 percent. If the prime rate climbs to 9 percent, your rate becomes 10.5 percent. Your monthly payment rises immediately because you are paying interest on a higher rate.
Many HELOCs include a rate cap — a maximum rate you will never exceed — but the cap is usually high (often 18 percent) and does not protect you from large increases. Some lenders offer a fixed-rate option for part or all of your HELOC balance, but this usually costs more and reduces the flexibility that makes a HELOC attractive.
What happens when the draw period ends
When your draw period ends, you enter the repayment period and can no longer borrow. Your lender calculates how much you owe and divides it by the number of years in the repayment period. You now make a full principal-and-interest payment every month, not just interest.
This payment shock can be severe. If you borrowed $30,000 during a 10-year draw period and made only minimum payments, you owe the full $30,000 when repayment begins. Spread over a 15-year repayment period at 8 percent interest, that is roughly $290 per month. If you were paying $200 per month during the draw period (interest only), your payment nearly doubled.
Some borrowers refinance into a new HELOC or home equity loan to avoid this shock, but that requires may have access to again and restarting the clock. Others take out a personal loan or use savings to pay down the balance before repayment begins.
When a lender can freeze or close your HELOC
A HELOC is not a may provide line of credit. Your lender can reduce your credit limit, freeze your account, or close it entirely if certain conditions change. This happened to many borrowers during the 2008 financial crisis when home values dropped and lenders cut off access to HELOCs overnight.
Common reasons a lender freezes or closes a HELOC include: your home value drops significantly (reducing your equity), your credit score falls below a certain threshold, you miss payments, you lose your job or income drops, or the economy enters a recession and the lender tightens lending across the board. The lender does not need your permission to make these changes.
If your HELOC is frozen during the draw period, you cannot borrow more, but you still owe what you have already drawn and must continue making payments. If you are in the repayment period, a freeze does not change your payment obligation.
HELOC versus home equity loan versus cash-out refinance
| Feature | HELOC | Home Equity Loan | Cash-Out Refinance |
|---|---|---|---|
| Interest rate | Variable (changes with market) | Fixed (locked in) | Fixed (locked in) |
| How you borrow | Draw as needed during draw period | Lump sum upfront | Lump sum upfront |
| What you pay interest on | Only what you draw | Full loan amount from day one | Full loan amount from day one |
| Repayment timeline | Draw period, then repayment period | Fixed term (usually 5–20 years) | Fixed term (usually 15–30 years) |
| Can lender freeze it? | Yes | No (once funded) | No (once funded) |
| Best for | Ongoing or uncertain expenses | One large expense | Refinancing existing mortgage |
A home equity loan gives you a fixed amount upfront and a fixed interest rate. You pay interest on the full amount immediately, even if you do not need all of it right away. But your payment never changes, and the lender cannot freeze your access once the loan is funded.
A cash-out refinance replaces your existing mortgage with a new, larger one and gives you the difference in cash. Your interest rate is fixed, but you are refinancing your entire mortgage, which means closing costs, a new appraisal, and a new 15- or 30-year term. This resets your mortgage clock and can cost more in total interest over time.
Risks and what to watch for
The biggest risk is the payment shock at the end of the draw period. Many borrowers underestimate how much their payment will rise and find themselves unable to afford it. Budget for the repayment period payment now, not when it arrives.
A second risk is the variable rate. If you borrow $40,000 at 6 percent interest and rates climb to 10 percent, your interest cost rises by thousands of dollars per year. You have no protection against this unless you lock in a fixed rate (which costs more).
A third risk is the temptation to keep borrowing. Because a HELOC feels like assistance programs during the draw period, some borrowers max out the credit line and then cannot afford the repayment period. Treat a HELOC as a loan, not a spending account.
Finally, remember that your home is collateral. If you cannot pay, the lender forecloses. A HELOC is not a substitute for an emergency fund or a way to cover ongoing living expenses you cannot afford.
Frequently Asked Questions
Can I pay off my HELOC early without a penalty?
Most HELOCs allow early repayment without penalty, but read your agreement to confirm. Some lenders charge a prepayment fee if you pay off the balance within a certain number of years, though this is less common than it was a decade ago. Paying early saves you interest and reduces the shock when the repayment period begins.
What if I cannot afford my payment when the repayment period starts?
Contact your lender before the payment is due. Some lenders offer a conversion to a fixed-rate loan or an extended repayment period, though this usually costs more in total interest. If you cannot afford the payment, you may need to refinance into a home equity loan or cash-out refinance, or sell the home. Do not ignore the problem — missed payments damage your credit and put your home at risk.
How much equity do I need to open a HELOC?
Most lenders require at least 15 to 20 percent equity in your home, though some require more. Equity is the difference between your home's current value and what you owe on your mortgage. If your home is worth $300,000 and you owe $250,000, you have $50,000 in equity. Lenders typically let you borrow up to 80 or 85 percent of your total equity.
What happens to my HELOC if I sell my house?
You must pay off the HELOC balance in full at closing, just like your mortgage. The sale proceeds go first to pay off your first mortgage, then your HELOC, then any other liens, and finally to you. If the sale price is too low to cover both debts, you may owe the difference out of pocket.
Can I have more than one HELOC?
Yes, some borrowers open a second HELOC with a different lender to increase their total available credit. Each HELOC is a separate second mortgage on your home. However, multiple HELOCs increase your risk because you have multiple lenders who can freeze or foreclose, and your total monthly payment during repayment can become unaffordable.
