No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Though it may be time consuming reaching out to the lender and kind of gauging there credit score tiers, dti requirements, and the form of loan needed will give you a better answer to pulling in a 50k plus loan,
If looking for a mortgage then yes; it's possible to pull in this type of money on just one loan.
However when looking at a debt consolidation loan try not to pay off debt fast for a quick turn around on the fico score.
Also find out what bureau that lender pulls.
For example DCU solely pulls equifiax or at least for my state , that said I'd only place emphasis on micromanging the equifax 8 or 4 score keeping in mind for some of us equifax pulls in alot of old data that may affect the score .
If however you know your paying down debt and let's say 30 days past and nothing is being reported go in online and start filing disputes (experian) is known to work and close disputes a bit quicker than outsourced transunion.
