I don't usually post on national or even Chicagoland housing prices in general. There are a thousand voices for that. I like to keep it specific to the properties my clients are looking at. In Chicago, it comes down to the block... and the actual property. Homes can be very diverse in a small radius.... prices just as diverse.
However, here's a group o' good reading on the subject:
Chicago: No boom means no bust?
Home Prices up or down?
Hurdles not insurmountable
