Typical deadzone. Denying facts. First, you provided a C-S for Philly. This is not Philly. Its not even Pennsylvania.
Case Shiller is far from perfect. It isnt even close to describing what is going on in SD right now.
I provided specific paired sales. I could provide them all day. I know the what the market was there 30 years ago. I sold my parents home back then. I have followed its value since then and it has at best doubled. I know what the market there is now. It is nothing close to up 200%.
The house I provided has doubled since 99. My house is up more than 4 times since 99. This is not the same everywhere. Its not even close to the same everywhere
And no one here has lodged close to as many personal attacks as you have. Im surprised you havent been booted yet
