Housing and real estate is up because there is a lot of international wealth investing and laundering money into the US and inflating the real estate market prices astronomically, knowing 99.9% of the people in the US can't afford in order to build their portfolio. Here's Supermodel Gigi Hadid's father - http://www.latimes.com/local/lanow/la-me-ln-developer-mohamed-hadid-bel-air-mansion-20151214-story.html - He essentially creates tax shells for himself and some of the wealthiest people in the world and develops property for them, like $60m mansions in an area where housing is a tiny fraction of that, but eventually pricing the neighbors out of their area. Not only are Mom & Pop shops unable to pay their rental space, corporate businesses like FedEx are being driven out of their spaces in these neighborhoods. This is happening all over LA, SF, and NYC where you would need to make roughly $150-$225k a year in order to comfortably live in a 2 bedroom apartment rental.
I'm sure its like the Tech industry where some analyst or hedge fund dip shit finds a trendy new app or product and creates some magical valuation out of his ass forcing the rest of the industry to follow suit.
