I am not sure the feelings of the group on Suze Orman, but I do listen/watch her show and periodic interviews. She has always said

“Never ever borrow against your 401k plan because you will pay double taxation on the money you borrow. Because you don’t pay taxes on the money you put into a 401k, when you pay back the loan (which you must do within five years, or 15 years if used to buy a home), you pay it back with money you have paid taxes on. Then, when you retire and take the money out again, you end up paying taxes on it a second time. And that isn’t even considering the penalties you have to pay if you change jobs/quit/lose your job, in which case the money is due immediately and subject to taxes and a 10% penalty.”
