My husband has a 401K from his old job with about $32,000 in it. It's at Vanguard, which is good, since all of our other investments are also at Vanguard, but we'd like to have a little bit more flexibility / control over it if possible. What can or should we do with it? Can we roll it over into an IRA? What are the costs / benefits to doing so, and what's the process? Thanks so much!
