I have 5 credit cards, ranging from $1,000 to $10,000 in credit limits. I'm currently using 88% of my available limit (according to Credit Karma). I recently got a loan from a relative in the amount of $10,000 to get my score a little higher while I apply for a mortgage. My total credit card debt is just over $20,000. What should I pay first? Should I pay off the lower balance cards, or get the higher balance cards closer to the suggested 30% balance? Thanks!
