No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I would personally recommend paying off the CC's first regardless. Even though you may qualify for a mortgage at present, your terms would likely be less-than-ideal. In my case, I ran into some issues not too long ago after changing jobs, moving and then being the only earner at home. Paying off the credit cards was critical, and in doing so freed us up to clean up our credit scores and give us a generally better standard of living.
Cheers!
