There's also a wide array of possible benefits to more people moving into your neighborhood, that don't really exist in a house. It's not just a larger tax base for public transit—there's also a greater potential for new restaurants, shops, etc to open, to serve the greater customer base. I suppose your new housemate could in fact be a master chef who is happy to share dinner most nights—but probably not.
