Distance, I don't really know. When I think about living in the same city, I instinctively think about my city, which allows for getting from one point to another relatively fast. Like, less than 15 minutes.
I think you can usually buy land in the same general area, so I would go as far as to say 'in really comfortable walking distance'.
But how one's feelings change as the distance increases would be worth going into more.
