Dear Liz: My current home mortgage rate is 5%. I owe about $340,000 on the house and have about $300,000 in equity. My credit union is offering a home equity line of credit with a rate of 3%. Would it be a good idea to take out a HELOC at that rate and use those funds to pay down or pay off my mortgage?
Answer: Prevailing HELOC rates are closer to 9%, so what you saw is likely a teaser rate that would eventually expire. After that, you’d pay the regular variable rate, which would rise and fall with prevailing interest rates up to a predetermined cap, which is usually 18%.
So no, it’s not a good idea to give up your current relatively low rate. HELOCs and other variable-rate loans are a better fit for short-term borrowing that you can pay off relatively quickly.
