I am writing an expository essay and i need some help?

that depends on what you like and what your tastes and interests are. One point could be about something you don't like about where you're at now and what you intend to make different about this "somewhere else" you're going to live at. Another could just be how great "somewhere else" is and what you like about it. The last point could be something along the lines of how this "somewhere else" will change your life.
