Super Congrats on your USAA Rate Advantage $6,000 SL!
That's their lowest APR card and a nice pickup. Well done!
BTW, in your signature file you note that your EX score
is 658 as of 11/16/2018. I assume that's a FICO 8 score.
But as you now know, USAA uses EX FICO 3 for credit card
approvals. I'm also a USAA member, and they always send
an approval notice via email with their approving EX 3 score. Once
you get it, if you wouldn't mind sharing that EX 3 score with us
for data point purposes, that would be great. Congrats again!
