My 2007 GE kitchen appliances for my new home funded with a WaMu mortgage may are similarly unimpressive as investments in 2024.
(And cherrypicking history is easy!)
And your mortgage probably makes you wildly over/under (but not correct) weight on residential real estate according to whether you consider it a payment you need to reflect in your portfolio or a part of your portfolio and therefore it's mising a justifying expenditure.
And you'd presumably have no exposure to industrial real estate, defense, anything b2b, ...
But it's a fun idea and I'll admit to similar irrational thinking when I was annoyed by Amex charging (and refusing to refund) me and my wife separately while I was in the middle of trying to talk to them about merging them/closing one. (Which reminds me, must do that soon before it happens again..)
