I've done it three times no problem (401K to IRA)
Now I'm trying to figure out a way to quit my job (which I like) for 1 day ... get that 401K $$$ outta there and just start over again.
after 8 years with the same company, for me, there's a growing reason why I gotta leave. staying another 12 will mean that I'll be poverty stricken in my old age. The 401K will be like this 30 year old midget who supposed to take care of me when I'm 59. Aint gonna happen.
One alternative I was thinking of : just bite the bullet, suspend 401K contributions for 6 months, fund a margin with that money and just double up the 401K contributions later.
