Book sales ($36,000 a year): Sales of How to Engineer Your Layoff" continue to be steady. I expect book sales to rise once the economy starts to soften and people get more nervous about their jobs.

Rental properties are defined as passive income with a couple of exceptions. If you’re a real estate professional, any rental income you’re making counts as active income. If you’re "self-renting," meaning that you own a space and are renting it out to a corporation or partnership where you conduct business, that does not constitute passive income unless that lease had been signed before 1988, in which case you’ve been grandfathered into having that income being defined as passive. According to the IRS, "it does not matter whether or not the use is under a lease, a service contract, or some other arrangement."
If you have specialized knowledge in a certain topic, you can put together an online course to teach others.
