In my case, cc interest was cut from 29 to 4% (B of A) Signature loan is 13%, but very small balance and I pay an additional $10/monthly up to $20/monthly, more if I can afford it. When the signature is pif, I'll toss that $45 onto the cc portion. Small Baby Steps.
Saving money trumps fico, imho. You CAN keep a credit card open that's NOT included in your account, but don't app for any new cards or they can cancel you out. So transfer whatever you can from a card to leave that open for yourself and pif that card monthly.
