I want to genuinely know

I just watched the Navy Federal Road to 20K in 95 Days video and had a couple quick questions based on where I’m currently at. Here’s what I already have in place: - Flagship checking account - Savings account - CD account - Just approved for an unsecured Cash Rewards card for $2,200 two days ago - Pledge loan that is already over 90 percent paid down What I am still missing: - Authorized user account - Tradeline - Money market savings account - Direct deposit (I am currently self-employed and will be opening my S Corp and setting up payroll through Gusto next month to establish this) I understand the next step is to let this new Cash Rewards card age for about 95 days before requesting a credit limit increase and then moving pre-qualify for second card? My main questions are: 1. For those of us who don’t have family or friends with clean, strong credit, what is the best way to legitimately get an authorized user account or tradeline without risking our profile? 2. For the money market savings account, is it okay to open it with a balance under $2,500 for now, even if it is something like $100? Appreciate everything you are teaching in this space. Your roadmap finally made this feel structured instead of confusing.
