Buffalo used to be a very wealthy city. It was the first American city with widespread electricity (thanks, Niagara Falls!), and because it's had some hard times, you can literally buy a mansion at (relatively) bargain prices and rent it out to half a dozen people, and you still get to keep the master bed and bath for yourself.
And there's the added bonus of living in a proud, blue collar city, where people care about who you are, and not what you're paid.
