In January 2018, I missed my chance of raising the rent on my new incoming tenants because it didn't come to mind until very late in the interview process. I didn't write about my previous tenant's sudden decision to move out in December 2017 after 1.5 years, because they provided a relatively seamless transition by introducing their longtime friends to replace them. I didn't miss a month of rent and didn't have to do any marketing, so I felt I'd just keep the rent the same.
CD Interest Income: I only have one CD account left in the amount of $185,000 paying 3%. It expires at the end of 2018 and I’ll have to figure out what to do with it. After selling my SF rental house in mid-2017 for 30X annual rent, I’m left with about $500,000 in cash after investing ~$2,200,000. The best CD today is the CIT Bank 12-month CD at 2.5%. That’s pretty darn good because just a couple years ago, such a CD was less than 0.5%. The yield curve is flattening, meaning folks should take advantage of shorter duration CDs.
Finally, make sure you can service multiple types of clients. This is the best egg to have. Even for something as simple as a dog walking business, you can service multiple types of clients. For example, you can offer a puppy walking service and an adult walking service. You can have weekends at the park services. You can offer to take the dog to the groomers. Try to meet client’s individual needs.

Joe started Retire by 40 in 2010 to figure out how to retire early. He spent 16 years working in computer design and enjoyed the technical work immensely. However, he hated the corporate BS. He left his engineering career behind to become a stay-at-home dad/blogger at 38. At Retire by 40, Joe focuses on financial independence, early retirement, investing, saving, and passive income.
And real estate does more than just track inflation – it throws off income (which is important to some people and useful to most). And while your underlying asset is appreciating, the income also grows as rents increase over time. And if you make smart and well-timed purchases, both rents and asset values can increase at well above the rate of inflation.

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.
The one thing I learned though from all those childhood experiences though is that you never can depend on one source of income. Eventually my mom caught on and stopped giving me all those extra bags of chips and I had to figure out a new way to make money. No matter how safe something seems there’s always the chance that you could lose that income and be stuck with nothing.
Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.

Great ideas here, and thanks for the link! I’m definitely interested in learning about using an Ebay store, although I’ve heard they are not as effective as they used to be. One interesting problem that arises though is with online work, that is, work performed via the internet. If one does not reside in one’s home country while doing it it might be considered illegal (so check on all those tax implications).

Ask yourself how many hours a week do you spend sitting in silence, coming up with an idea and working on your idea? We’re so busy with our jobs that our childhood creativity sadly vanishes at some point in our lives. There are food bloggers who clear over $15,000 a month. There are lifestyle bloggers who make over $10,000 a month while living in Thailand. And there are even personal finance bloggers who’ve sold their sites for multi-millions.

Didn’t I say you can monetize pretty much any hobby? If you’re a gamer at heart, then you’ve probably heard of Twitch.  It’s a streaming site where you can watch people play video games. The more popular streamers on Twitch make thousands of dollars a month from fan donations. Fortnite player, Ninja, recently explained how he made $500,000 in ONE MONTH by streaming his gameplay. Of course, it helps if you’re the best of the best in your game and have Drake play with you.
My personal finance blogs were started with $100, but you can start a blog with $20 if you buy hosting on a monthly basis. That’s 4 Starbucks coffees or 4 packs of cigarettes many paycheck to paycheck people do find a way to buy. After six months of HARD work, my first site started generating $2,000 a month, and today, those three sites generate over $5,000 a month, while all I have put in was hosting for $100-ish every year each, and a website redesign for under $1,000 after three years. Freelance writing and translation jobs are also a sizable part of my income that did not require any upfront investment. Investing $10 a month in index funds is also a realistic way for many to build yet another income stream.
6) Always Remember That Everything Is Relative. The best way to determine worthwhile passive income streams is by comparing the likely return (IRR) with the current risk-free rate of return. If I round up, the 10 year bond yield is at 3%. Any new venture should thoroughly beat 3% otherwise you are wasting your efforts since you can earn 3% doing nothing.
The first time I did affiliate marketing was way back in the day on my architecture exam website. I connected with a company that sold practice exams, which gave me $22 for every person who bought one of their exams via my site. Since then, I’ve generated over $250,000 simply by recommending that product alone. Again, this is a product that was not mine, but one that has still been helpful to my audience. This was all done with thousands of visitors a month. Not millions, or even hundreds of thousands.
Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company. has an advertising relationship with some of the offers included on this page.
