A home equity line of credit (HELOC) is a revolving credit line secured by your home, similar in structure to a credit card but backed by your equity and typically offering a much lower rate. You draw against it as needed during a "draw period" (often 10 years), then repay during a separate "repayment period" (often 10-20 years).
Who it's best for
Homeowners with a specific, often ongoing or uncertain-size expense — a phased renovation, tuition paid over several years, a financial cushion they may or may not actually use. The revolving structure is the whole point: you only pay interest on what you've actually drawn, not the full approved line.
Why people get a HELOC over a home equity loan or cash-out refinance
- You only borrow what you use. Unlike a home equity loan, you're not paying interest on a lump sum you drew and haven't spent yet.
- Reusable. Pay down the balance during the draw period and that credit becomes available again, much like a credit card.
- Leaves your first mortgage untouched. If your existing mortgage rate is well below current rates, a HELOC lets you tap equity without refinancing that first loan away.
Risks to understand
It's still a lien against your home — missed payments put your house at risk the same as your primary mortgage. And when the draw period ends, the repayment period's required payment (principal plus interest, versus interest-only or minimum draws before) can jump substantially. Know your specific draw-to-repayment timeline before relying on one long-term.
HELOC rates, draw periods, and repayment terms vary significantly by lender. This is general information, not a recommendation to borrow against your home.
