Thank you to everyone who posts in these forums: your info is always helpful and encouraging.
I went on a bit of an app spree last week and here are the results (good, bad and ugly):
Chase Sapphire Reserve: Approved, $17,000
PenFed Platinum: Approved, $20,000 (but required sending tax returns, quickly approved after that)
Amex Hilton Surpass: Approved, $1,000 (rendering it basically useless since any Hilton stay of more than a few nights would take a deposit for more than that)
Citi Costco Business: Declined (Citi apparently doesn't like me - nothing shows up on the prequal site either)
Amex SPG Business: Declined (I called for reconsideration and they said it might require another hard pull, so I passed on that)
All three of my scores are in the 690 range. Now to the garden for a few months or longer.
