Also, find out the sanctuary amount from the old 401k provider. They may call it something different, but bottom line is that some providers have a lower bounds limit to how much u can hold before they close your account involuntarily. You DO NOT want this to happen. For instance, If the limit is $3k and we have a market crash and your $4. 5k drops by half, that may put you below the sanctuary value and automatically close the 401k. They would then automatically sell the holdings and cut you a check without you knowing it, leaving you both with an actual loss and scrambling against the clock to put it into an IRA or face penalties.
