Ten years ago, conventional large-lot housing in wealthy suburbs was the highest-priced housing, per square foot, in nearly all metropolitan areas. Today, housing in walkable neighborhoods is typically the most expensive; the lines crossed in the 2000s.
The Atlantic writer Christopher B. Leinberger • Noting the evolution in housing from the suburb back to the city. As housing values have gone down significantly, cities have started to come out back on top again. In particular, Leinberger notes the example of the D.C. metro area: The Metro system largely paid for many of its stations by having property owners pay more in taxes for a handful of years, then watched as their neighborhoods flourished. As a result, housing values in those areas have decreased at a much lower rate than that of the suburban areas which used to cost more. This should be a major hint for even mid-sized cities that they should invest in mass transit. (Hat tip to The Awl, which focused on the auto end of this argument.) source
