So I do think both P1 and P2 are going to apply in Dec for INK UNLIMITED. If it were you, would you bother with reducing credit limit on other existing Chase cards prior to applying? Our bizs are sole prop, no EIN, and very low revenue...if you get my drift. None of the below cards have any current spend/balance on them, 800+ across the board. Probably not worth the hassle to reduce I'm thinking, but maybe I'm an outlier.

P1 has:
Chase Sapphire Reserve, $34.0K
Chase Ink Biz Preferred, $16.5K

P2 has:
Chase Ink Biz Preferred, $10.5K
