A home equity line of credit is a revolving limit secured against your house. It is approved once, and after that you draw what you need, pay interest only on what you have drawn, and repay and redraw as often as you like.
Think of it as a credit card with your house behind it, at a fraction of the rate and with none of the forgiveness if things go wrong.
The mechanics
Lenders will generally approve a standalone HELOC up to 65 percent of your home’s value. Combined with a mortgage on the same property, the total can reach 80 percent.
So on a home worth 700,000 with a 300,000 mortgage, you have roughly 260,000 of room, being 80 percent of 700,000 less the mortgage.
The rate is variable, quoted as prime plus a small margin, and it moves when prime moves. Minimum payments are interest only, which is both the appeal and the danger.
What it is good for
Renovations where the cost is uncertain and staged. Bridging a gap between buying and selling. A down payment on a cottage or a rental. An emergency reserve that costs nothing until used. And consolidating debt when you want flexibility rather than a fixed schedule.
What it is bad for
Anything you would struggle to repay. Interest-only minimums mean a balance can sit unchanged for years while you pay steadily and owe exactly the same amount.
I have met people who drew on a HELOC for a kitchen in 2018 and still owe the full amount. Nothing went wrong. They just never paid principal, because nothing forced them to.
HELOC or refinance
Take the HELOC when you want flexibility, when you are not certain of the amount, or when your existing mortgage rate is too good to break.
Take the refinance when the amount is known and fixed, when you want the discipline of a set payment, or when you want a fixed rate rather than one that moves with prime.
For a defined debt consolidation, the refinance is usually the better instrument, precisely because it forces principal repayment.
Set it up before you need it
You have to qualify for a HELOC the same way you qualify for a mortgage, with income, credit, and the stress test. Which means the moment you most want one, after a job loss or an unexpected bill, is the moment you are least likely to get it.
Arranging one while everything is calm costs you nothing to hold and it is there if life changes.
If you are wondering whether a line of credit fits what you are trying to do, would it help to talk it through?
