Downpayment on American Express Platinum

[Addam Driver]

Ok.  Seriously.  I finally decided to get the AMEX Platinum card.   I like the perks that come with it.  Being a RE investor, I figure, why don't I put the downpayment on my Amex, and treat myself to a vacation once I finish the project.  Now, I am well aware that most banks don't allow for this, but I  have to ask.  Has anyone done something like this?  Even if you have the physical cash to cover the purchase?  Any good "Creative Financing" ideas?  ...legally of course.

Cheers!
