Start at your local city hall. Consider parking if you plan to teach at home. Ask students to park only in front of your house, not a neighbor's. If not, you may need to park you own car out of the complex on teaching days so students can use your spot. One of the surest ways to anger your neighbors is to have students park in their assigned spots or across their driveways.
Angry neighbors cause business problems, as well as social ones.
Close off the non-public portions of your home to keep students from wandering about. Children, especially, are very nosy and wish to poke in your cabinets, etc. Speak to the parent at the second infraction. Consider dismissing the student at the third. Don't leave dangerous things lying around, such as kitchen knives.
