This is mostly passive once you have it all set up, but it does take a lot of work at the beginning. Real estate investing also requires occasional maintenance. Currently, we invest in a couple of rental properties and earn about $500 profit from each per month. You can read more about my rental properties at How and Why I Became a Landlord.
Investing in bonds: Similarly, bonds are an attractive way to engage in passive income. Over a recent 45-year period, bonds funds, as measured by Vanguard Funds, returned 7.1%. Of course, there's no guarantee that investments in stocks or bonds will always work out well, investing in them is by far the surest way to generate money through passive income.
Use your base to build your audience, and when you’re starting out, take advantage of the fact that you don’t have a big following to give more personalized help to your first fans. “The people who are starting out — that’s their advantage,” says Flynn. “They have the opportunity to speak directly with those people few coming their way to find out what their problems are and give them the special treatment that bigger brands might not be able to do.”
Thanks for asking. gives a good summary of the definition I use. But in brief, it’s income that isn’t proportional to the time you physically put into acquiring it. It doesn’t mean it’s not without work or effort. It’s just that most of the work is done up front and it continues to pay off long after that initial effort. Real estate fits into that box. There’s definitely a spectrum but compared to what we do as doctors, where our compensation is directly linked to our time, most of these things are quite passive.

Another benefit of investing in rental properties is the loan pay down. If you obtain a loan to buy the property, each month your tenants are paying off part of the loan. Once the mortgage on the property has been paid off, your cash flow will increase dramatically, allowing your mediocre investment to skyrocket into a full-fledged retirement program.
​Network marketing, or multi-level marketing, seems to be on the rise. Companies such as Young Living Oils, Avon, Pampered Chef, and AdvoCare are all multi-level marketing companies. You can earn passive income through network marketing by building a team underneath you (often referred to as a down line.) Once you have a large team you can earn commissions off of their sales without having to do much.
The beauty of passive income through online courses is that it has huge scalability potential and you earn no extra expenses for more students enrolling. Online courses are conducted through digital study material. Students simply pay to access and view. So whether you sell a course to 5 students or 500 students, it doesn’t cost you extra (aside from the time spent promoting your course).
If you’ve ever thought to yourself, “I wish there was a product that did this,” then invent it! Create a product, medical or otherwise, and sell it as a company or get royalties for it. It’s not impossible to figure out, I have many friends who have taken a concept to market. Don’t overlook an invention as a fantastic means of attaining passive income.
There is also an idea that we should work to build a passive income asset and then sit on the beach relaxing for the rest of our lives. The truth is that most people would get extremely bored with this scenario and will be eager to find something to do. That’s why the world’s billionaires continue to work… they love what they do and it stopped being about the money a long time ago.
