House-sitting business involves staying at or checking up on a customer’s house or apartment while they are away on vacation or business. Your house-sitting services may include taking care of pets, watering plants, mowing the lawn, checking that appliances and heaters are running properly, collecting and holding or forwarding mail, and making sure the home is secure. You may have house-sitting charges by the day, or have a flat rate and charge extra for each chore that you do. Check with your insurance agent to see if you should be bonded.
