This is a fairly new concept to me still, but I now see that multiple streams of income are definitely far better than one high income stream as you point out. I now work part time as a hospitalist. That job provides our biggest income stream, but I also work part time for an opioid treatment center, which could easily turn into a full time position if I ever needed it (the owner has told me “you always have a job here”). Additionally, my wife works full time AND she runs an airbnb room out of our home which pulls in easily 1000/month. Those combined with our investments in stocks/bonds give us 5 sources of income. In the past we relied solely on my full time work and it stressed me out knowing that at any time something could happen that could take that away from us (as you listed above). Since I started doing these other things and we diversified our income, I feel much more at ease and relaxed.
Some good writing here! I am a realtor myself and frequently get in touch with clients that consider buying a realty estate a conservative of investing. I once heard of a transport company in Vienna, Austria, which focused their entire profit on buying eventually every house available in the downtown for about 80 years. That must be some of a passive income!

Investing in real estate: Investing in real estate offers more passive income cash potential - but more risk - than investing in stocks or bonds. You'll need substantial amounts of cash to invest in buying a home -- it usually takes 20% down to land a good home mortgage loan. But history shows that home prices usually rise over time, so buying home a for $200,000 and selling it for $250,000 over a five-year time period, for example, is a reasonable expectation when investing in real estate.
This one may seem simple, but that’s only because it is. If you were to move your savings from a traditional, brick-and-mortar bank with a low-interest rate and into a high-yield savings account online, over time you can make a surprising amount of extra cash. Online banks are FDIC-insured just like the traditional brick-and-mortar institutions, so your money is just as safe.
Mr Raman, age 32, works for a bank as a senior manager. He earns Rs 50,000 per month take-home salary. His wife works as a school teacher earning Rs 15,000 per month. Raman had, earlier in his career, sold life insurance policies as an agent earning roughly Rs 50,000 per annum (Rs 4200 per month) as renewal commission every year from those policies sold. Raman has a flat of his own plus a small investment property in neighbouring suburb giving him Rs 15,000 p.m. rent. Raman has a decent small savings portfolio giving him an interest of Rs 5,000 per month. Raman believes he will increase his savings income from Rs 5000 to 15,000 in 5 years time as he plans to save all of his annual bonus (Rs 1.5 lacs per annum) every year.
One word of advice, and something I intend to do once I have the money saved up, is to build or buy out property that can support apartments or townhomes. One tough mistake some people make is buying a pair of homes to rent out and they get a nice $2,000-$3,000 a month but that’s it. Buying a house is expensive and the rental prices keep lower income families from potentially coming to you with their money to rent. If you have an acre to work with (more or less is OK too) you should be talking to a contractor to build apartments or townhomes. You will make a little less per unit BUT your audience grows significantly because now you can have college students, single parents, older folks, etc. all able to afford your rental units AND instead of capturing one $1,000-$1,500 a month payments, you can probably charge $700 a month per unit (or more, depending on the market) and build maybe 3, 4, 5, 10 units for the price of a home or two and now you’re making something like $2,100-$10,000 a month. It all depends on what you have to invest but if you’ve got $250,000+ I’d highly suggest you talk to a bank/investor that can get you in touch with a good contractor to build on a property and get permits and take out a matching $250,000 loan (I’ve read that $500,000 is plenty to build a good amount of apartments to start) and you can fill up your apartments and make a killing every month. You’ll have more tenants to deal with but if you’re competitive with your pricing you won’t have a hard time keeping tenants or replacing them.
You may think of a savings account as just that, savings. But it’s actually another form of income as the money in the account will draw interest. And while this interest may be small, it’s still better than $0. Eventually, you can invest this money whenever an opportunity presents itself in order to gain other income streams.  Look into Tax Free Savings Accounts if you are going this route.

Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
"I found out at about PJ because we happened to be in the same place at the same time ... some people call that a coincidence; I call pure and solid good luck. We quickly learned that we both were in business to help other people succeed, but little did I expect it would be PJ who helped me (instead of the other way around). I am now on target to have over 40,000 students take my online continuing education and training course. And all because of some simple tricks-of-the trade taught by PJ. I would recommend PJ to people who need to create an online business and also want to ramp that business up so that it can become a full time income. In Great Faith, Cathy He helped make it possible for me and when you put into practice what he teaches, it can possible for you, too. "
Maybe you’re obsessed with homemade jewelry and want to sell your wares on Etsy. Or, perhaps you’re well-versed on the Amazon reselling game and want to earn extra cash finding unicorns (rare and valuable products) and reselling them for profit. Maybe you’re obsessed with a specific topic and want to start a blog that can one day bring in advertorial and affiliate income.
One of the most appealing options, particularly for millennials, would be #12 on your list (create a Blog/Youtube channel). The videos can be about anything that interests you, from your daily makeup routine (with affiliate links to the products you use), recipes (what you eat each day) or as you mention, instructional videos (again with affiliate links to the products you use). Once you gain a large following and viewership, you can earn via Adsense on YouTube.
Nice list. What keeps my family from getting more streams is the time it takes. I would actually be willing to work part time in medicine and make less money with a side-hustle just to keep things fresh and prevent burnout. That requires some degree of FI and some time to read about the new endeavor. Maybe when my kids are both in school, we we see. Until then, I’ll keep reading your posts for ideas.

For example my business is a LLC taxed as a S corp. I am active in it and my wife is not. She owns half the company because she fronted the money to start the company (but is not active at all in the business). I get paid a W2 salary for my work I put into it and any profits are distributed to my Wife and I as “dividends”. However the dividends are still taxed as active income at the higher tax rates.
Residual income is income that a person continues to make after the work he has put into a project has been completed. Residual income is different from linear income in that linear income refers to someone’s salary. Salaries are paid based on the number of hours someone works in the present, rather than the royalties someone can earn on work that was done in the past. To explore this concept, consider the following residual income definition.
"The whole idea of Multiple Streams of Income will be a powerfulparadigm shift for most people. Bob Allen gives practical andbeautifully illustrated knowledge on how to do it. Masteringfinancial principles is an important habit in life because it givesus the freedom to focus on what matters most. A valuable read."—Dr. Stephen R. Covey, author of The 7 Habits of HighlyEffective People
I guess I just don’t understand why the specific importance of focusing on “dividends” instead of focusing on the total return of your investment, including stock appreciation. I don’t really care if a company decides to issue a dividend or not; presumably, if they don’t issue a dividend, then they’re doing other things to increase the value of the company, which will be reflected in the stock price of the company. As an investor, I can make money by selling a percentage of my holdings or collecting dividends, and I don’t really care how that’s divided up – it’s an artificial distinction.
Active income, on the other hand, involves earning money in exchange for a service. It could be a salary, an hourly wage, commissions, or tips. It’s essentially a trade of your time for a fixed dollar amount. Most people choose to live this way, and there’s nothing inherently wrong with that, as long as you understand that there will be a limit to how much money you can realistically earn.

Though it can take a while to build up enough cash to put a 20% down payment on an investment property (the typical lender minimum), they can snowball fairly quickly. The key here is to correctly project income and expenses in order to calculate cash flow (the free cash you can put in your pocket after all associated property expenses have been paid). However you have to be sure to include the cost of a property manager in your calculations unless you want to manage the property yourself. Even with a property manager, you may be required to make large repair decisions every now and then – so while this is not a 100% passive activity, you are not directly trading your time for money like traditional employment.
I agree mostly with the real estate advice. I’m looking for ways to take advantage of the condo I own to get up the rent from ~$0.90/ft to the $1.2-1.5/ft that seems more like the range in the same area. I’d have to put in a bit of capital (probably 10k on the low end for just the basics up to 40k if I wanted to remodel the kitchen and 2 bathrooms up to par with the area), so the return is likely there if those upgrades warrant $1.30/ft (given the unit is larger than most 2br/2ba in the area).
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.
Ebooks, which can be published through sites like Amazon Kindle Direct Publishing, are an increasingly popular option. Because these books are self-published, the process is quicker, allowing you to build residual income faster than the traditional publishing route. Whether it’s a romance novel or a how-to book on fly fishing, you can create a book and have it available for purchase in a matter of weeks.
Stock dividends: Some stocks, especially stocks from big corporate standouts, pay dividends to shareholders based on the number of shares they own, and the percentage of the stock price on the dividend date. For example, if a company pays out 3% on a stock that's trading at $100 per share, you'll earn $3 for every share of that stock you own. Add it up and that can be good take-home pay as a passive investment.
And, there’s no way to build up a base of subscribers like that unless you’ve been doing this for years and years. The unfortunate truth is that they profit off of your naivety. If you don’t want to have your hopes shattered, realize that you’re in this for the long haul. If you want an eventual life of leisure, able to roam the planet as a digital nomad and make absurd amounts of money online, you have to put in the sweat equity.
The primary philosophy behind the residual income model is that the portion of a stock's price that is above or below book value is attributable to the expertise of the company's management. Accordingly, it becomes a handy tool for calculating what the "real" value of a stock is. It is important to note, however, that analysts should pay special attention to incorporating changes in book value per share caused by share buybacks and other unusual events that may distort the analysis.
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.
