My wife left her job in November. At her last company she had a 401k with Merrill Lynch that is worth less than 50k as of right now. We are still young and I expect between the 2 of us we'll have 5 or more retirement accounts with various companies before we are FIRE. I am not sure what we should be doing with the account? I guess we can keep it, or roll it over into another vehicle, and I'm just not sure which option to choose or why. I'm not even sure what options there ARE. (We definitely don't plan to take any money out). Can she ADD to this account from her new job (that I don't think uses Merrill lynch for 401k)?
Also, I have a TSP. If (when) I leave my job, should I just leave it there. I *think* the consensus I've seen around here is that TSP has good investment options with very low fees, so basically manage it, but don't ever close my account or pull money out until I am ready to start withdrawing money.
I do LIKE the idea of having money centrally located so when we eventually retire we have 1 agency to deal with. I could open an account and just roll over retirement accounts when we leave our jobs. Can anybody help, even if it's just explaining what options are available it would be helpful.
P.S. I tried to search the forums prior to asking this question, but got a network error. If there's a thread for this already, I can read that to ejumacate myself first if somebody can post a link.
