If you want to, you can just try to be nice and go to their house with some homemade cookies and just say, "Welcome to the neighborhood, I'm (your name here). If you have any questions about where to find anything, feel free! I live right at (your address here)."
But then again you don't want to be too helpful and seem kinda annoying. Be nice, but not too "in their face." Just go up to their door and knock and try some of my tips.
