No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
What is your current age of accounts? How many credit cards do you currently have? If you already have 3-5 cards, I wouldn't bother. I did the SCT for three Comenity cards and two of them actually ended up doing a hard pull, so you have to be careful about it. If you don't really need the cards or wouldn't frequently use them, I wouldn't do it. They may help with your mortgage score, but that depends on what your current derogs are that are holding your score down.
