Armstrong thoroughly expects that BW#2 after 2018, probably 2020ish.
I don't think the housing bubble v2 can last that long with rising interest rates, amongst other variables like a fragile bond market selling off to push rates further, with those previous factors also heavily favoring a stock crash. So, in other words, either some heavy inflation will be engineered in the near future or some big events should occur sooner than that Armstrong timeline.
