Well, I think the people who bought 2013 and onward and have big debt loads could have some trouble but in general even if a house goes up, doesn't really make it a bad investment. As long as you don't treat it as a casino and long-term wealth builder like people do.
Home prices going up sucks for most people too, they just don't know it. Then they get hit with increased insurance, property taxes, etc and whatever paper wealth you have from the houses valuation you can't really use unless you borrow against it. And unless you wanna switch states, you can't really sell the home and make much $ because the home prices going up is all relative.
Seems like you could build tons of housing where all these malls/stripmalls that are going to go out of business are. Or put old folks communities there or something. A lot of land if people get creative with it. Wonder if that will create downward pressure on home prices over time, and then obviously any breakthroughs in transport will as well.
