Working full time at minimum wage, the most a single person should be paying in rent is $387 a month. Virtually no one pays that little, even when they are splitting rent costs with another person.
Obviously the Triangle does not have the housing problems that New York and cities in California have; that is why I stated in the text "The Housing Wage for a two-bedroom unit at Fair Market Rent in North Carolina—$14.17—is below the 2013 National Housing Wage of $18.79 (and well below that of densely populated states like California and New York).
But even though the cost of living in the South is comparatively cheap I don't think you can say that rent costs aren't disproportionately high-- esp. in urban areas like the Triangle. It is less a question of does this housing exist than it is are people being paid enough to afford it. And if they're not, shouldn't rent come down accordingly?
Re: “Some facts about affordable housing”
As much as I'm in favor of communal everything including housing, I don't think that splitting a 2BR between more than two people is ideal.
You're saying builders are going to keep building expensive housing nobody can afford? Housing is not "affordable" if no one can can afford it.
Everyone loses?
