What is a HELOC and how does it actually work?
A HELOC, a home equity line of credit, is a credit line secured by your house. Think of it as a credit card with your home as the backing and a much lower rate: you get approved for a limit, borrow only what you need when you need it, and pay interest only on what you've drawn.
The two phases
Every HELOC runs in two acts. The draw period, commonly ten years, is when you can pull money out, pay it back, and pull again, often with interest-only minimum payments. Then comes the repayment period, commonly twenty years, when the line closes and you pay back principal plus interest.
The classic surprise is the transition between the two. An interest-only payment on an $80,000 draw might run a few hundred dollars a month; when repayment starts, the payment can double or more. Nobody should sign a HELOC without knowing that second number.
Variable rates, in practice
Most HELOCs float with the prime rate, so your rate moves when the Federal Reserve moves. Rising rates mean rising payments on whatever you've drawn. Many lenders offer fixed-rate conversion on portions of the balance, which is worth asking about when you compare offers.
When a line beats a lump sum
A HELOC shines when costs arrive in stages: a renovation billed over months, tuition due each semester, a safety net you may never touch. You avoid paying interest on money that would otherwise sit in your checking account. If you need one known amount all at once, a fixed-rate option like a cash-out refinance is often the better tool; we compare the two in this guide.
What it takes to qualify
Lenders look at your equity (see how much you can actually borrow), your credit, and your income. Requirements vary more than most people expect, which is exactly why comparing lenders matters: the same borrower can see meaningfully different limits, rates, and fees from different institutions.
