Owning property can earn you passive income for decades to come. Once you purchase a duplex, home, or apartment building as a rental property, you’ll earn a consistent monthly income with little work. Rent should cover your mortgage, taxes, repairs, and other expenses. You’ll continue to earn income by paying off your mortgage with the rent money and saving excess rental income.
Great breakout of some common items that are (mostly) accessible to individuals. My biggest issue with p2p is the ordinary interest it generates and the ordinary tax that we have to pay. That really takes a bite out of the returns. Fortunately, I opened an IRA with one of the providers to juice the return with zero additional risk. 6-8% nominal returns over a long period of time will make me very happy. It should end up as 5-7% of the portfolio anyway, so nothing too significant.

People have a lot of stuff—and they’re always looking for inexpensive ways to store it. What could be easier than having people pay you to store their stuff? Building passive income by offering storage could involve a large-scale investment of buying a storage facility (with cash!) or something simpler like offering your basement or shed. You’ll just need to ensure their items are safe and secure.
But, you don't need to go further than that. You can simply write it and publish it and collect the income. That's all. Send out a couple emails to your list (if you have one) or post it on social media, and there you have it. Passive income. Now, the amount of income you receive depends on the quality of the book you've written. How well did you craft the message? How targeted was the information to your audience? It counts.
One thing I’ve realized is this: It’s FAR easier to work for an employer than it is to develop durable passive income streams for the average person. Why? Because working for an employer in a place that “needs” you means that it’s possible to show up and give a 50% effort. You can show up, put in your time, go home, have a beer, watch TV, and rinse and repeat all without REALLY having to put in the effort.

Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
