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.
But when so many turn down leasing one and one-half acre for one Wind Turbine for each 80 acres, that lease certainly does not materially affect the rest of the Farm or Ranch grazing pasture and the lease pays much more than the farm crow or grazing pasture lease, just because some lawyer said the lease was too long: 30 years plus 30 year option = 60 years, and the wind turbine company has selling production/electricity contracts for the next 150 years – which is needed to obtain financing!
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.
The Second Bill of Rights is a list of rights that was proposed by United States President Franklin D. Roosevelt during his State of the Union Address on Tuesday, January 11, 1944.[1] In his address, Roosevelt suggested that the nation had come to recognize and should now implement, a second "bill of rights". Roosevelt's argument was that the "political rights" guaranteed by the Constitution and the Bill of Rights had "proved inadequate to assure us equality in the pursuit of happiness". His remedy was to declare an "economic bill of rights" to guarantee these specific rights:

One of the things I'm surprised your article doesn't mention is the tax advantages of this type of investment. The depreciation and rehab costs (purchasing distressed properties) can be huge deductions to ones income taxes, which none of the others have. Then, along with the appreciation of real estate, this passive income investment outperforms the notion of maxing out my 401k as well.
I own several rental properties in the mid west and I live in CA. I have never even seen them in person. With good property management in place (not easy to find but possible) it is definitely possible to own cash flowing properties across the country. Not for everyone and not without it’s drawbacks, but it seems to be working for me so far. I’m happy to answer any questions about my experience with this type of investing.
You must sacrifice the pleasures of today for the freedom you will earn tomorrow. In my 20s, I shared a studio with my best friend from high school and drove beater cars worth less than 10% of my annual gross income. I'd stay until after 7:30 p.m. at work in order to eat the free cafeteria food. International vacations were replaced with staycations since work already sent me overseas two to four times a year. Clothes were bought at thrift shops, of course.
If you’re curious about my own streams of income, I encourage you to check out my income report for an in-depth look. For now, though, I will tell you that I’m currently at twelve streams, beginning with my day job as an anesthesiologist, and ranging from crowdfunding to owning an apartment building, and to this very blog. Ultimately, having these multiple streams of income has proven to be invaluable to me–not only because of monetary value but because they allow me to live the life I want, and I feel I have a hedge against whatever the future might throw at me.
A good portion of my stock allocation is in growth stocks and structured notes that pay no dividends. The dividend income that comes from stocks is primarily from S&P 500 index exchange-traded funds. Although this is a passive-income report, as I'm still relatively young I'm more interested in building a large financial nut through principal appreciation rather than through dividend investing. As an entrepreneur, I can't help but have a growth mindset.
Don't mistake passive income with zero work. It's still work, it's just that your income is not directly tied to the hours worked. Anyone who owns rental properties knows that it's considered passive income but there is quite a bit of work involved. The work is front heavy but if you are lucky, you can collect rental checks without incident for many months before having to do work.
The second category of passive income is drawing on sources that do not require capital to start, maintain, and grow. These are far better choices for those who want to start out on their own and build a fortune from nothing. They include assets you can create, such as a book, song, patent, trademark, Internet site, recurring commissions, or businesses that earn nearly infinite returns on equity such as a drop-ship e-commerce retailer that has little or no money tied up in operations but still turns a profit.
I enjoy how you lay out real numbers. A lot of people wouldn’t do that. While you admit that you are somewhat conservative, I think the $1M in CD’s is just too conservative. Assuming you don’t need the cash flow now (which you say you just save anyways) then all that could be invested for potentially higher returns. For example, what if you bought San Francisco real estate along the way instead of CD’s. Or, an SP500 Index fund. I bet your average return would have been higher than 3.75%. Sure you could lose it, but the point is if you don’t need the cash flow now, you should try to increase that nut as high as possible until the day you actually need it. Your nut could be $5M right now if you had invested in asset classes other than CD’s for the last 14 years. Don’t get me wrong, you have done far better than me, but I guess I would take a little more risk if you don’t rely on that cash flow.
What I did:The first two years of work in NYC was brutal. I told myself there was no way I could work on Wall St for my entire career because I’d probably die from heart failure by age 40. Having an early death in my mind willed me to save 50%+ from the first year onward and devise a CD, real estate, and stock investment distribution system for my savings every year. I thought about starting this site for at least a year before I hired someone from Craigslist to give set me up and push me forward. Hiring someone to get started is totally worth it if you are a master procrastinator. You can now learn how to start your own site with my step-by-step guide to save yourself time and money. 
However, this comes back to the old discussion of pain versus pleasure. We will always do more to avoid pain than we will to gain pleasure. When our backs are against the wall, we act. When they're not, we relax. The truth is that the pain-versus-pleasure paradigm only operates in the short term. We'll only avoid pain in the here and now. Often not in the long term.
Dividend Income: Dividend income is wonderful because it is completely passive and is taxed at only 15% if you are in the 25%, 28%, 33%, and 35% income tax bracket. If you are in the 39.6% income tax bracket you will pay a 20% tax on your dividends. My dividend income portfolio mainly consist of dividend equity and bond ETFs such as DVY, VYM, MUB, TLT, and IEF. Total stock and bond income is a little over $100,000 a year due to a heavy accumulation of stocks and municipal bonds after selling my house.
It is very important to understand that contacting a “professional” to learn how to do this only results in them trying to sell me crap properties (whether high end or low end). I’ve tried contacting realtors out of state, and they attempt to sell me crap or someone else’s problem. No one has a vested interest in actually helping someone or teaching them about how to get an out of state rental. very frustrating. I could go out tomorrow and buy a rental in my city, but that is the last place I want to own one. Anyone? Are there an real people on here?
It covers Rental Income (Real Estate) or Interest Income (Bank Deposits). Though it is best suited for retirement planning but it can also act as second income during working years. Big question is how to fix the target for Second Income. Very simple, if your Monthly Expense is 50k & residential property can yield rent of 25k then you need 3 residential units i.e. one for self and two for second income source.

Stocks (shares) paying dividends are typically a reliable source of income but they have higher risk of capital losses than cash and bonds. So, it’s wise not to chase yield indiscriminately.  The 10 highest yielding stocks on the ASX 200 (the 200 largest companies in Australia) are shown in the table below.  But their share price performance on average over the last year has been underwhelming, as shown in the far right column:

A perfect example of the Active Problem Solving + Automation concept is in my online courses I’ve created over the years, or my free webinars I’ve created more recently Each of my online courses and webinars are targeted to help people with specific problems, whether that’s in the area of affiliate marketing, podcasting, building a brand, and so forth. I am always improving upon the courses, but they are also evergreen for my audience.

From what he describes, creating passive income definitely does not sound easy. It requires a serious ramp-up -- often requires 80- to 100-hour workweeks in the beginning, says Flynn. But once up and running, and depending on the content, some sites take fairly minimal maintenance. Green Exam Academy, the LEED exam study site he launched in 2008, takes just him four to five hours a month to maintain but brings in $250,000 annually.

I’ve never invested in real estate (except to live in), but am always intrigued by communities like FS who seem to have such a passion for it. My intrigue stems back to my earlier comments that the long term trends in appreciation in real estate are simply not very competitive versus equities, despite what Robert Kiyosaki had to say in his book, Rich Dad, Poor Dad.
The source of pension payments is determined by the portion of the distribution that constitutes the compensation element (employer contributions) and the portion that constitutes the earnings element (the investment income). The compensation element is sourced the same as compensation from the performance of personal services. The portion attributable to services performed in the United States is U.S. source income, and the portion attributable to services performed outside the United States is foreign source income.
