Where does Gandalf live

I don't know how I missed this before, but I think it's an interesting point.
Getting a "base" could be the first step, for one in a position of power and authority like the Istari, toward a mindset of domination and empire-building. After all, they were fundamentally the same creatures as Sauron. Gandalf may have deliberately kept his feet wandering not only to explore hearts and minds to see what he had to work with, but also to keep himself out of the "fortress" mentality that Saruman fell into.
