Cap1 is very BK friendly but you should have waited 3-6 months. You could try a secured card or if you want another unsecured, try Milestone. They even have a preapproval so you dont waste an inquiry. You can try discover prequal as well. Good luck on your rebuild.
Hi, welcome to the post-BK journey! +1 to waiting 3 to 6 months for apping.
It was 6 months after Ch7 DC that I got CreditOne, then within another two months Cap1 and Discover It, and a month after that Victoria's Secret via Shopping Cart Trick softpull, then NFL Rewards Visa. Just a note about CreditOne, my starting SL was $400 and they gave an auto CLI of $200 (to $600 SL) when my 1st statement cut. As far as I have read on here, they don't seem to do auto CLIs after that, but will charge you to do a CLI for you which is ridiculous. I'm just letting you know that CreditOne doesn't appear to be a card that will grow much at all, so I would recommend getting better cards as soon as you're able, which it sounds like you already plan to do. But CreditOne hitting your CRs should improve your scores and make that easier.
Also, it's really important to have an installment loan for credit mix. I have a student loan, but if I hadn't I would have found a CU that offers a credit builder loan. The following post is how I found this forum. It goes into detail on how to rebuild and, while I haven't followed it to the letter, it has given me a plan of action:
