Hi folks, This is a bit of a basic question, but I've learned to rely on you all for good advice, so I hope you don't mind. My wife and I just bought our first property - an IP with her on the loan and on the title, based on advice we received from accounts/lawyers (I'm a Yank with an Aus PR). The loan is with ANZ and they're offering her a Qantas Platinum Mastercard / Amex with fees waived as part of their loan package, though they won't give her the 50,000 bonus points she'd normally receive if she just signed up outside of the ANZ Breakfree package. I already have a Westpac Qantas Black card, with her as a secondary cardholder. So, a few questions: Is there any compelling reason that I'm missing for her to get the ANZ Platinum card? Are there any compelling reasons for her not to get the ANZ Platinum card? Is it okay if we make payments related to the IP using my Westpac card, or her secondary-cardholder card, and will she run into any trouble when it comes to IP-related expenses, tax-deductions, etc? Are there any other good CC-related options/approaches that would be better than either of the above? Maybe I'm overthinking this (probably), and maybe I'm being blind to some obvious considerations (probably), and that's exactly why I'd appreciate your inputs. Thanks in advance.
