@SUBCMC Recommend you also look at Vanguard, E-Trade, etc to invest in mutual funds. USAA has changed raised their some of their fees for trading in the past couple of months so they are not as attractive as other companies.
SUBCMC, Great question! I have sent you an email on usaa.com with helpful information regarding your daughters. Please login and review this at your convenience. You may respond to me with any other questions or concerns. We are always happy to help. Have a great weekend, ~Jen
