Who it fits
A HELOC fits homeowners who want a flexible reserve or are funding phased projects, and who want to preserve a low first-mortgage rate. It fits less well if you need a fixed payment or a one-time lump sum — a home equity loan may be better.
Frequently asked questions
Is HELOC interest tax-deductible?
It can be when funds are used to buy, build, or substantially improve the home securing the loan. Confirm with a tax advisor.
What’s the biggest risk?
A rising variable rate and over-borrowing. Because it’s secured by your home, discipline matters.
HELOC or home equity loan?
