This can be a little easier said than done, but if you have a large social media following, you can definitely earn money promoting a product or advertising for a company. You can even combine this with different marketing campaigns if you are an influencer and have your own blog (advertisement + affiliate income). This is how many bloggers make money! Again, it is not 100% passive but once set up correctly and then scaled, can be surprisingly lucrative.

Let’s continue the vintage BMW idea. Old cars obviously require quite a lot of maintenance. Many people will buy a “fixer upper” with the intention of spending their spare time repairing and restoring it. There’s a very obvious market here: a guide to restoring different BMW models. Depending on your knowledge, you could produce detailed guides for the three or four most popular models and sell them. Not everyone restoring a car will buy them, but some probably will.
Even if each patron only contributes a very small amount each month, it can still be a huge source of income. Take a look at the Patreon page for Kinda Funny, an internet video company. They have over 6,209 patrons which means an average of just $3 a month would be a monthly income of almost $19,000 – plus they get cheerleaders that are always happy to spread the word on their brand.

One of the easiest ways to increase your passive income is to shift your savings to a bank that pays a higher yield on your savings — for example, Discover Bank and EverBank pay almost 1% for your money. Although it doesn’t sound like much (especially in this low interest environment), little things do add up and eventually interest rates will rise.

Bullshit. If you have a job, you have marketable value. Maybe it’s low value, if you’re flipping burgers, but you can create value somehow. I don’t care if you have to start out by re-renting the parking spot in front of your apartment, you can find, create, or buy something valuable worth repeatedly selling or renting, or you’re not thinking hard enough. Here’s a free idea: A lot of people want to play with 3D printers. Get 5 of your friends together and buy one. Put up a website and a listing in the local paper. Charge $50/h for printing. Set up a system that verifies if payment has been submitted and then automatically prints out the files that have been emailed to you. Split the earnings with your friends. Boom. You have passive income.
If you go this route, be prepared to put in quite a bit of work up front. All of these products need to be created, tested and perfected for sale. The good news is that your initial investment will pay off multiple times. Also, there aren’t any production costs as you aren’t making any physical products. But you will still need to devote some time to product development and subsequent marketing, meaning that your work schedule may need to be trimmed a bit.
Reinvest your passive income. Once you've started earning a good amount of passive income, you can reinvest that income to earn ever more. This income will then produce further income that you can also reinvest. This cycle produces ever-increasing income streams without any direct cost to you. For example, you could reinvest revenue from website advertising into more advertising that brings readers to your site. This increase in traffic would then further increase your ad revenue.[12]
For those of you who don’t want to come up with a $220,000 downpayment and a $900,000 mortgage to buy the median home in SF or NYC, who don’t want to deal with tenants or remodeling, and who wants to not do any work after the investment is made, check out Fundrise. They are my favorite real estate crowdsourcing company founded in 2012 and based in Washington DC. They are pioneers in the eREIT product offering and they’re raising an Opportunity Fund to take advantage of new tax favorable laws.
Renting value is exactly what you do when you go to work every day. This is a great way to adhere to our rule against one-time consumption, although you can only rent something to one person at a time (drawback). By renting something, I can generally avoid degradation of the value, or at least lessen it. By renting you a house, I’m charging you for the value of the shelter and comfort, and in fact incur pretty minimal decrease in value as your usage of the house causes wear and tear. When you’re done renting the house, there’s still plenty of value left to rent out, and the fact that you’ve enjoyed a year or two of value doesn’t much matter to the next willing consumer.
In Eric Reis’s The Lean Startup, a fantastic book about how today’s entrepreneurs and startup companies are approaching the way they create and innovate, Eric talks about how vital it is to use validated learning and scientific experimentation to be able to steer a company in the right direction. In other words, to use customer feedback and quantified data analysis (of real, non-vanity metrics) from a minimal viable product to make decisions and pivot a business one way or another.
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.

It’s a (mostly) short term, higher risk, higher reward place to invest cash that has a low correlation with the stock market, but is far more passive than buying and managing properties, has more opportunity for diversification than private placements (minimums of 5-10K, rather than 100K), and most of the equity offerings (and all of the debt offerings) provide monthly or quarterly incomes. Unlike a REIT, you can choose exactly which projects you wish to invest in.
"What makes business work is creating value. If you're going into the business with the intention of not creating value, but of having it magically provide money for you, then you often make really bad choices. The business that you're investing in or creating doesn't tend to be creating value for its customers or for anyone. So it doesn't tend to spit off the cash you're hoping it will. So many times I've seen people pursue passive income, and end up having active losses instead. They just spend a lot of time and money trying to push responsibilities off on other people and having it not work."
* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances. They’ve also got great tools for x-raying your portfolio for excessive fees, recommending a more optimized asset allocation, and planning for retirement with their Retirement Planner.
