The advantage is that you'll be able to instantly have him move in, especially if you do what I do and exit the world when I get a bound NPC. If you don't have a house, and he dies, you'll not only have to build a house, but then wait for him to respawn, and if you already have a house for him, then he'll reappear sooner than if you hadn't built a house for him.
