Here's a stupid question...

I know this question probably seems odd, but I really have no idea! Why is the cost of living so low in Pittsburgh?

It is usually determined by the availability of land. While the Pittsburgh area is hilly, the land can still be utilized unlike the mountains outside of LA or SF. Also it is determined by supply and demand. Pittsburgh has been pretty stagnant as far as population growth. Without as much demand for land and housing, the price will usually remain the same of even go do.
