The best passive income business is rental income. If you have a vacant room, you may invite the interested party to rent the space. Ask for 3 months advance deposit to make sure the renter won't escape. Another, if you only have one car in a wide garage, better divide it and invite someone to rent a parking space. This is a sure way to always have money and income saved. What do you think, is this good for you? It is good for me.
