A HELOC is a revolving line of credit secured by the equity in your home. It works much like a credit card: you're approved for a credit limit, you draw funds as you need them, and you pay interest only on the outstanding balance — not on the full limit.
HELOCs have two phases: a draw period, commonly around 10 years, during which you can borrow repeatedly and often pay interest-only, followed by a repayment period during which the outstanding balance amortizes down to zero.
How it works
Say a homeowner is approved for a $50,000 HELOC. They draw $20,000 for a kitchen remodel in year one, pay it down over the next two years, then draw another $15,000 for a bathroom renovation in year four — paying interest only on whatever balance is outstanding at any given time, not on the full $50,000 limit.
Because the credit line is revolving, it behaves differently from a traditional loan: you can borrow, repay, and borrow again throughout the draw period without reapplying, as long as you stay within your approved limit.
When the draw period ends, the HELOC moves into repayment, and any outstanding balance is amortized over the remaining term — often 10 to 20 years — meaning the payment typically increases at that point since it now includes principal, not just interest.
When it matters to you
HELOCs matter most for ongoing or staged expenses where you don't know the exact total upfront — a renovation completed in phases, or a multi-year expense like tuition — because you only borrow (and pay interest on) what you actually use.
They matter less for a single, known, one-time need, where a fixed-rate home equity loan often makes the cost more predictable from day one.
Common mistakes
- Treating a HELOC like free money because it's revolving, and drawing more than the original plan without a repayment strategy.
- Not planning for the payment increase when the draw period ends and the balance moves into amortized repayment.
- Forgetting that a HELOC is secured by your home, meaning missed payments carry the same foreclosure risk as a first mortgage.
- Comparing a HELOC only against a home equity loan without also considering a cash-out refinance, which can sometimes be the cheaper path depending on your existing first mortgage.
FAQs
How is a HELOC different from a home equity loan?
A HELOC is a revolving line of credit you draw from as needed, paying interest only on the outstanding balance. A home equity loan is a lump sum disbursed all at once with a fixed repayment schedule from day one.
What happens when my HELOC draw period ends?
The line moves into a repayment period, during which the outstanding balance is amortized — typically over 10 to 20 years — and you generally can no longer draw new funds.
Is a HELOC a good option for renovations?
Often yes, especially for projects completed in phases, since you only borrow what you need at each stage and pay interest only on the amount actually drawn.
