Someone in another thread mentioned a 401k loan as an option to finance a wedding. If anyone is thinking about this be VERY CAREFUL!!! If you do a 401k loan, you can only payback 2 ways. Through payroll deduction or out of the 401k monies themselves. BUT if you use the 401k monies they will get all the tax penalties as an early withdrawal.
OTHER warning. If you get laid off or your company folds you might have to pay the balance of the loan off in 90 days. They said the only way to do that was take it out of the 401K and get the penalties. Even if I got the cash from another source to pay it off, I couldn't
I took out a 401k loan a few years ago to refi my house. Alomost ran into this problem when my company was about to close. THANKFULLY the company ended up restructuring and kept me on part time, so I am still on payroll deduction. Dodged a HUGE bullet there.
