How limited is limited time with Chase, typically?
It truly varies from card to card. I'd guess a month or so, but that is just a guess.
It seems like I remember them running it last year for about a month.
I wasn't planning on getting a Chase business card until the end of the year to maximize my waived yearly fees
The annual fee is applied at card activation date not calendar year.
but 60,000 points is hard to turn down.
Yes, it is.
If you are married, it's wise to rotate the Ink products with the CSP between you and your wife, so at all times you can transfer UR points to/from each other and your Freedom/Ink cash cards without doubling up on unnecessary annual fees.
