My credit score dropped from a 764 to a 742 because I paid off a motorcycle loan in about 1 year. How can I get my score back up, just as fast as it dropped? I'm sure this is only a dream :/
742 is still a very good credit score so I wouldn't be all that concerned personally; however, if you're worried then sign up with CreditKarma.com and monitor your score for free.
They will also give you suggestions on how to raise your credit worthiness and score.
