There was a time when I have been very cautious about using credit, and definitely one way to make sure that you don’t get the opportunity to abuse it is to close it.
However, as time goes by, there are times when opportunity presents itself, or a crisis presents itself when the best course is to use credit, so apparently the best policy to make sure you keep your credit line as high as possible.
For instance, you are given 5 credit cards with 10,000 dollars line each, and your balance is $6,000. You may think that since you use only $6,000, you can cancel 4 of your credit cards. But that is not so good. It looks like you are using $6,000 of your $10,000 credit which seemed that you are overextended. However, if you continue to use only $6,000 out of $50,000 that you have, then you are only using 12 percent of your available credit, which looks better to creditors.
As long as it is not too expensive to maintain the credit line, and make sure that you are prudent in using it, the advice seems to be to get the credit line, but to utilize less than 50 percent of it unless necessary.
