Need some feedback ln next steps for my girl credit. The images are from today. She still got a young profile with only 2 primary credit cards and one active auto loan. She got a few small personal/payday loans for $1k each that she paid off and closed from like 1-2 years ago. I was able to get her on my granny Cap1 card as a AU that should be posting in the next week or so (21 years old, no late payments, $0 balance and a $7,500 limit) which I think will boost her score up more. My question is, should she add a few more credit builders to add more personal accounts or should she maybe apply for another credit card and let them age and request CLIs on the 2 she got already?
