I have 4 cards, low limits. 500 discover secured, 500 savor, 500 venture one, 1k Amex blue cash everyday.
I do not want 4 cards long term but I would like to have 1-2 moderate limit cards.
Which cards should I focus on to limit increases? I plan on closing the others in about a year. I like rewards/cash back but don’t have a preference to which. All cards have no annual fees.
