I need other opinions on this. I want to know if this is a good idea or not. I have a balance of 62,452 on a Heloc loan, at an APR of 8.5% monthly, so roughly 425 a month, interest only payment. I can get a loan out on my 401K for 46,000. The twice-monthly payments,or per check payment, will be 483.54 exactly, for 5 years for 401k loan. I plan to make more payments. Here's my question, is it better to pay off the majority of the HELOC with 401K and save hundreds in interest and I pay myself back, or just leave as is? I can take out and pay back the HELOC at will, just like a credit card.
