The salary you must earn to buy a home in 27 metros
I found this report interesting and it speaks to the affordability of many markets as well.

There were also some surprises at least for me. For instance, Ohio was more affordable than Detroit and Atlanta is still affordable despite the fact that most posts I have seen seem to imply it has already run up. Obviously, using the median home price is dangerous for some markets as many metro markets have good and really bad areas but it still might be interesting.
