In certain pockets of the country, homebuyers are choosing the city over the suburbs as home buyers re-evaluate urban areas. This demographic shift is occuring as baby boomers get older and many urban areas have largely seen a cultural renaissance over the past 10 years.
Growing suburbs are now experiencing the problems of their neighboring urban areas and homebuyers are now considering moving farther out where land is cheaper but the commute is longer.
With oil prices rising, this makes for an interesting situation since commuting costs will rise making the feasability of a long distance commute less likely to be sustained.
