If the answer is yes, then rollover all funds to Vanguard (or Fidelity).

See the IRS rollover chart for a breakdown of the alternatives open to you.Also, buy and hold investments are common in self-directed IRA accounts, but flipping much less so. 

If your above the limits then you need to look at insurance products for your kids when they are very young that roll over to cash annuities after about 10 years to help pay for estate taxes so they don’t have to sell.  

Another idea is to possibly rollover your 401(k) into a self directed IRA.

I had a roll over self-directed IRA burning a whole in my pocket and I tried to give money to every operator I met - not a good plan.
