I had just opened two new personal (installment) accounts. My score did drop 10-12 points. I have found that maybe 5 points was from the new accounts. The rest was more usage of my credit (revolving) accounts. I just wanted to share with everyone that an installment account by itself has minimal impact but when you combine both installment & revolving accounts that are open together it has more positive impact on the score because of the credit mix.
