It's the lowest-cost loan available
Robert Gordon, senior financial adviser with Investor Solutions in Coconut Grove, Fla., says a 401(k) loan could be a useful option for people who have problems getting credit at affordable rates -- for example, someone whose credit score has plummeted because of bankruptcy or a short sale.
"When they get ready to go into the market, instead of subjecting themselves to two (percent), three (percent) or four percentage point increases in rates or not getting credit at all, (a 401(k) loan) could be a resource," Gordon says.
Just remember that the interest you save by choosing a 401(k) loan over a bank loan still might not be enough to make up for your loss of earnings from taking the money out of your retirement account.
