Pay off credit cards in one lump sum, or spread over a few months?
I know you say you are aware of secured and unsecured debt and you've made your decision.  Did you do the numbers?  You will pay 44k over the life of the mortgage for that 24k (Based on 4.5% APR mortgage). Once you refinance your mortgage, do you plan on using credit for a while?  Lots of Americans are hyperfocused on credit scores.  The only times it affects your life are when you finance something, when you apply to rent a house or apartment, and sometimes when you apply for a job.  Credit score should not be a factor in this decision. You're borrowing the money at a lower rate to pay off the high rate cards because you want to pay less in interest.  Considering #1 is there any reason NOT to pay off the cards immediately, if not sooner?
