Linda, The advice from Mr. Krance to make this your last resort is spot on. While using the loan feature of your 401(k) can occasionally (stress on "occasionally") be part of a sound planning strategy, more often than not it simply offers a temporary deferral to a structural imbalance. Before proceeding, please make certain your circumstances don't fall into the later category. Best Wishes
Contact the human resources department of your employer. I recommend you be certain this is your last resort. Don't allow the current you to hurt the future you.
Agreed gentlemen, I would also say to be aware that if you leave the job or were let go for any reason the loan becomes due immediately or is then considered a fully taxable distribution which may cause other tax issues. Just thing you need to be aware of.....best wishes.
