Urban Market Real Estate Values

[Alton Williams]

I am familiar with the Detroit Real Estate Market (I can hear @Joshua Dorkin's sarcastically laughing) and I understand completely why/how the values can change by 80k up or down when you travel 2 blocks in either direction. My question to the community is, do you experience this in the other urban markets out there. Baltimore, Philly, Atlanta, D.C. etc? Is there extreme variation all across the country or is this just a Detroit specific thing?
