Just curious, why would you close "an old Chase Manhattan Bank Visa"? And how old is "old"?
Have to say I balk a bit at closing any credit line, although I have threatened before to have AFs waived!
You're right, 42 accounts is a bit much!!! I have a hard enough time keeping up with my 10 credit cards and making sure they all show some usage every few months. Not sure I could manage many more!
I agree, after 2 1/2 yrs. you're probably never going to see any kind of decent CL on that card. And better to have it closed by you than notated in credit reports "closed by creditor" from lack of usage if you sock drawered it!
