This is an example of passive income that isn't quite as passive as it may seem. Yes, if you own one or more homes or apartments you can collect regular rent checks from your tenants. But in exchange for that, you need to keep the properties in good working order, along with insuring and paying taxes on them. You may need to chase down rent checks from some tenants, too, and you may have several months without rent checks when you're between tenants.
 If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle that allows you make money fast. And right now, they’ve got a promotion going on where any new driver will instantly get a $300 bonus after completing their 100th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (and that’s in addition to your normal earnings).
