Rental properties are defined as passive income with a couple of exceptions. If you’re a real estate professional, any rental income you’re making counts as active income. If you’re "self-renting," meaning that you own a space and are renting it out to a corporation or partnership where you conduct business, that does not constitute passive income unless that lease had been signed before 1988, in which case you’ve been grandfathered into having that income being defined as passive. According to the IRS, "it does not matter whether or not the use is under a lease, a service contract, or some other arrangement."

Annuities and retirement plans are generally lower risk instruments for generating income. Annuities pay out a certain guaranteed income for the lifetime of the life assured while retirement plans typically payout a monthly or annual income for a period of time. Both of these can be useful for retail investors to create a base income as part of a bigger portfolio to reduce overall portfolio volatility resulting from market fluctuations and uncertainties.
In addition to an extra income stream, residual income allows you to diversify your revenue sources. Instead of relying on your standard paycheck, you’re earning money through the royalties of an eBook or the sales of an online course. Diversity of income gives your overall financial portfolio more security and depth. Similar to passive income, residual income gives you more financial stability, flexibility with your lifestyle, additional retirement savings, and a more robust financial standing.
Add Leverage (Mortgage) and you greatly increase the ROI especially from the perspective of using Rents (other peoples money) to pay down the mortgage and increase your equity in the property over time. At this point then yes price appreciation is secondary bonus and we have an arguement of how and why Real Estate can be better than Growth Stocks in some scenarios and for some investors.
In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.

Dividends made sense 40 years ago as a relatively simple rule of thumb, but after all the work done by John Bogle with index investing, and academics with Monte Carlo sims and the 4% rule, dividend investing just isn’t the simplest, cleanest way to invest or receive passive income anymore. It’s actually significantly more risky compared to index investing, because dividend companies are a much smaller share of the total global economy compared to the broader indices.
Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.

Nobody gets early FI investing in bonds, CD’s, or even stocks unless they make a huge income or are extremely frugal or a combination of both. Paper assets just don’t provide enough returns. Business income can be great but it is typically not as semi-passive as I would like and there is a relatively high failure rate. That is if you can monetize an ideal to begin with. RE investing needs to be higher ranked IMO as a way that the “average guy” can become FI.
Those who can reap the benefits of residual income have typically put in an immense amount of effort and time in the beginning to be able to enjoy the rewards later on. Residual income, therefore, does not result in instant gratification. Those interested in earning residual income must have a lot of patience and determination to work as hard as necessary to achieve their ultimate goals of a long-standing income stream.

The best illustration for this principle is a residential property investment: you renovate a multi-family residence, then collect rent every month. Royalties from creative works (books, films, music recordings) are also a form of residual income. Finally, entrepreneurship comes with a host of residual income-generating opportunities. Say you take after Richard Branson, create 400 companies assign a CEO to each, then let the dollars roll in. Or you create a co-op with professionals in your field, who leverage their results by compensating you for your initial investment in them. Finally, the online world is chockfull of residual income opportunities—but more on that in a separate section below.
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.
If you know anything well, a place, how to fix something, how to make something, how to do something, you can write a guide for it. You can sell your guide as an e-book, offer it as a download for a fee on your site or reach out to bloggers with similar content and ask if they will offer it as a paid download on their website (for a price of course).
The trial court ruled in Karen’s favor and signed a proposed divorce decree that had been drafted up by Brad’s attorney. Neither party appealed the decree. After the divorce, however, Karen’s monthly income began to progressively decline. As a result, she filed a petition in July of 2007 alleging that Brad had violated the terms of the divorce decree. She also proposed an alternative argument that perhaps the divorce decree was too vague and needed to be clarified. The trial court found that the decree was, in fact, too vague, and ordered it to be clarified.

Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
