In general, it’s a good time to get a HELOC if the prime rate isn’t going to rise sharply over the loan’s term. That’s because the prime rate, a benchmark rate used to calculate many variable interest rates, largely determines HELOC rates. If it goes up, your loan becomes more expensive. If it goes down, you can potentially get away with paying less than borrowers with comparable fixed-rate loans.
Of course, no one can predict the future but the prime rate has been climbing for several years. At the end of 2024 it sat 3.5 percentage points higher than where it had been in early 2020.
Ultimately, it’s impossible to predict with certainty where the market will go. If you’re considering a HELOC, make sure that you can afford the payments at both the loan’s lowest and highest possible rates. (All HELOCs come with a “ceiling,” which sets a limit on how high your rate can rise at any time during the loan term.)

Should I get an interest-only HELOC?
An interest-only HELOC can be a great way to access cash and enjoy low monthly payments for an initial period. However, once the draw period ends, your payments can skyrocket. That’s why it’s only a good idea to use an interest-only HELOC if you have a solid plan in place — one in which there’s no doubt that you can afford the monthly payments even if they adjust up to the rate cap.
If you’re not sure, ask your lender to help you crunch the numbers on your highest and lowest possible payments.
