Hello, Newbie here. I have an ESA acct, 529 account and a "529" custodial account for my son. They were opened since he was 1 year old and now he will be going to college for the 2018-2019 year. My question is: Which account do I use first to pay for his college expenses? I am thinking of using up all the ESA account first then the 529 account then use the 529 Custodial account last. I am not sure though if this is the right sequence in using these funds. Any advise will be greatly appreciated. Thank ypu.
