Thanks. Since a mortgage isn't a goal for another 2+ years, I figure an Auto loan for a used car might make sense in terms of 'other credit'. Thing is, while I agree on not getting credit for the sake of it, I do want to have at least one Amex card so I can rack up miles/rewards as I am self employed and want to prove myself with them over time. I can't just have a jewelery card and 2 $300 cards, you know what I mean?
It's been a dream of mine and having a REAL credit card with a high limit might be worth a temporary lowering of age. I would use it for sky miles as I am self employed and want to have at least one that is for personal use for things like vacations/etc once or twice a year.
That said, I wouldn't ever add any other credit cards.
