MSB asked:

I know that applying for a new card will reduce my FICO, and that increasing credit limits (while keeping debt amounts constant) will increase my score – but this would not be the case if requesting the increase in credit limit is treated as a new credit card application?

Des-n-Jes asked:

I currently have 3 credit cards. I just got approved for another and it is in the mail on it’s way. I paid off the one with the lowest credit limit, and was thinking about cancelling it and just keeping the other three.

I have been working on building my credit for a long time, and it has been very difficult. Will cancelling this card hurt my score? Or will having too much available credit hurt it? Which is worse? What should I do to keep working on getting my credit score higher?
To sum it up, is it worse that I cancel the one card, or is it worse that I may have too many cards? I also have a loan on my car and loan with American General. They are always paid on time.
