Trading a Paperclip for a House?

Want to know how to trade one red paperclip for a house? This guy is doing it, although he’s not quite there yet. He traded the paper clip for a fish pen, and then the fish pen for a door knob, then the door knob for a coleman stove someone didn’t want, and so on. His current item is a full year’s worth of rent in Phoenix, AZ! The place looks pretty nice, too.
