Somewhat different area, but earns me around $300 a month- Churning credit cards for rewards. So called “award/travel hacking”. 2 new credit cards per calendar quarter, conservatively estimate each signup bonus is worth $600 (if you know how to redeem them, usually that means for travel). Have to live in the U.S. and have good credit to do it, but I’ve been at it for a few years now and haven’t paid for airfares or barely any lodging costs on almost all my travel. Working on an online class that teaches how to do it, looking to sell that for some “real” passive income.
