If you have owned your home for a few years, you may be sitting on a valuable resource: home equity. A home equity line of credit (HELOC) lets you borrow against that equity as you need it, often at a lower interest rate than credit cards or personal loans. Homeowners use HELOCs for renovations, large repairs, education costs, and other major expenses.
Because your house secures the loan, though, a HELOC carries risks that unsecured borrowing does not. This guide explains how a HELOC works, how much you can borrow, how it compares with other home equity options, and what to check before you sign.
What Is a Home Equity Line of Credit?
A HELOC is a revolving line of credit secured by your home. Instead of receiving one lump sum, you are approved for a maximum credit limit, and you can borrow, repay, and borrow again up to that limit during a set period. In that way, it works a lot like a credit card, except your house serves as collateral.
Your home equity is the difference between your home’s market value and what you still owe on your mortgage. For example, if your home is worth $400,000 and your mortgage balance is $250,000, you have $150,000 in equity.
How a HELOC Works: Draw and Repayment Periods
The Draw Period
During the draw period, which commonly lasts around 10 years, you can withdraw money as needed using checks, online transfers, or a card linked to the account. Many HELOCs allow interest-only payments during this stage, which keeps payments low but does not reduce the amount you owe.
The Repayment Period
Once the draw period ends, you can no longer borrow, and you begin repaying both principal and interest, often over 10 to 20 years. Payments can jump significantly at this point, so it is important to plan for the change long before it arrives.
Variable Interest Rates
Most HELOCs have variable rates tied to a benchmark, such as the prime rate, plus a margin set by the lender. When the benchmark rises, your rate and payment rise too. Some lenders let you lock a portion of your balance at a fixed rate, which can add predictability.
How Much Can You Borrow?
Lenders usually limit your combined loan-to-value ratio (CLTV), which is the total of your mortgage and HELOC compared with your home’s value. Many lenders cap CLTV somewhere around 80% to 85%, though limits vary.
Using the earlier example with an 85% limit:
- Home value: $400,000
- 85% of value: $340,000
- Minus mortgage balance of $250,000
- Possible HELOC limit: up to $90,000
Your actual limit also depends on your credit score, income, and debt-to-income ratio.
HELOC vs. Home Equity Loan vs. Cash-Out Refinance
HELOC: A flexible, revolving line of credit with a variable rate. You pay interest only on what you actually borrow. Best for ongoing or uncertain expenses, such as a renovation done in stages.
Home equity loan: A lump sum with a fixed rate and fixed monthly payments. Best when you know exactly how much you need.
Cash-out refinance: You replace your existing mortgage with a larger one and take the difference in cash. This can make sense when current mortgage rates are lower than your existing rate. Our guide to cash-out refinancing explains how it works in detail.
If you already have a low mortgage rate, a HELOC lets you tap equity without giving up that rate on your primary loan.
Smart Ways to Use a HELOC
- Home improvements: Renovations such as a kitchen remodel, new roof, or added living space can increase your home’s value.
- Major repairs: Foundation work, HVAC replacement, or water damage repairs.
- High-interest debt payoff: Replacing expensive credit card debt can lower your rate, but only if you stop running up new balances.
- Emergency backup: Some homeowners open a HELOC and leave it unused as a safety net, though fees may apply.
Uses to Avoid
Using your home to pay for vacations, everyday spending, or speculative investments is risky. If your plans do not work out, you could end up owing more than you can repay, and your home is on the line.
Risks of a HELOC
- Foreclosure risk: Because your home is the collateral, missed payments can eventually lead to foreclosure.
- Rising payments: Variable rates and the switch from interest-only to full repayment can raise your payment sharply.
- Falling home values: If home prices drop, a lender may freeze or reduce your credit line, and you could owe more than the home is worth.
- Fees: Watch for appraisal fees, closing costs, annual fees, inactivity fees, and early closure fees.
HELOC Requirements
While every lender is different, most look for:
- Meaningful equity in your home, commonly at least 15% to 20%
- A solid credit score, with the best rates reserved for strong credit
- A manageable debt-to-income ratio
- Verifiable, stable income
- A satisfactory home appraisal
How to Get a HELOC: Step by Step
- Estimate your equity. Check your mortgage balance and research your home’s approximate value.
- Review your credit. Correct any errors and pay down balances where you can.
- Compare lenders. Get quotes from your current mortgage lender, local banks, credit unions, and online lenders.
- Compare the full terms. Look at the margin, rate caps, draw and repayment lengths, minimum draw requirements, and all fees.
- Apply and get appraised. Provide income documents and allow the lender to appraise your home.
- Review and close. Read the final disclosures carefully before signing.
For a HELOC on your primary residence, federal law generally gives you three business days after closing to cancel without penalty. The Federal Trade Commission explains this right and other protections in its guide to home equity loans and home equity lines of credit.
Is HELOC Interest Tax Deductible?
Under current IRS rules, HELOC interest is generally deductible only if you itemize and use the money to buy, build, or substantially improve the home that secures the loan. Interest on funds used for other purposes, such as paying off credit cards, typically is not deductible. Because tax rules can change, confirm your situation with a tax professional.
Frequently Asked Questions
Does opening a HELOC affect my credit score?
The application usually results in a hard inquiry, and the new account appears on your credit report. Making payments on time helps your credit over the long run.
Can I pay off a HELOC early?
Usually, yes. Some lenders charge an early closure fee if you close the line within the first few years, so check the terms.
Final Thoughts
A home equity line of credit can be one of the most affordable ways to fund big expenses, especially home improvements that add value to your property. The flexibility is powerful, but so is the risk, because your home secures every dollar you borrow. Shop multiple lenders, understand how your payment will change over time, and borrow only what you have a clear plan to repay.
