The cost of living in those areas will drive away all but the execs and the independently wealthy.
In 2013, I lived in a decent studio apartment (2 miles from the Pentagon and Crystal City)...heat, electricity included....$1,150 a month. 15 ft by 35 ft. Plus was safe area and Metro-bus within 300 of the front door.
I’ll bet by 2021 when this is up and running...that same studio apartment will be $2,000. And a two-bedroom will likely be going for $2,750.
Just for decent housing within 25 miles...I’ll bet everything escalates 40-percent by 2021, and probably reaches close to 200-percent by 2030. It’ll be like San Francisco in the 1980s/1990s.
