I have a saving secured loan with my credit union that I opened up 5/11 with a balance of $3,800 @ 2.4 %. As of today 4/29 the balance is 2,622, and I was thinking about opening another one for about $5,000 -$6,000 @ the same interest rate. I know I will save on interest if I pay the first loan off then open another. My question is what action will help my FICO score the most? I have two credit cards in the mix as well one with a  $2200 limit , and another with a  $1500 limit I keep my cards under a 10% balance PIF the day after my statement closes each month to avoid  interest charges.
