There's actually a good article on this: http://www.mrmoneymustache.com/2011/10/06/the-true-cost-of-c...

Basically, the idea is that for every mile you live closer to work, you can afford another $15,900 worth of house.

It's also interesting when you throw in cycling to work; I used to argue with a friend about going to the gym (which I'm not fond of). I told him I could bike to work (20 minutes) and bike home (20 minutes) for a total of a 40 minute workout during my commute and save myself the extra hour (maybe more) it would cost going to the gym everyday.

Workout at a gym is not really comparable to a bike ride.

You're right; I get a better workout biking home against the wind than I do on the step mill!
