Twilight, I would say "the usual" damage. Which would typically be the inquiry hits and new accounts factoring in. As always with any spree you would also want to be cautious of any of your lenders looking at this as you dramatically seeking credit. That causes AA's at times, which I am sure you know. But it is always a slight risk.

That brings your AoYA to one year, and all of your inquiries will become unscorable. That should also eliminate "too many recently opened accounts" as a reason for denial.
If the Citi card is the only thing left on your to-do list and you really want to get it done, I think you'll be OK in six months. But I'd garden for at least six months after that, letting everything else become a year old.
Good suggestion Heaven. I didn't even catch that in the signature. Giving it a year would be a wise move.
