The thing is, I’m not talking about buying brick-and-mortar buildings. I tried that many years ago with my father-in-law, and with devastating results. We tried to buy a duplex once, and the deal fell apart after we realized we weren’t really prepared for the purchase. I secretly wanted to become a landlord, but at the same time, I knew it wasn’t for me.

Cantillon develops a circular-flow model of the economy that shows the distribution of farm production between property owners, farmers, and workers. Farm production is exchanged for the goods and services produced in the cities by entrepreneurs and artisans. While the property owners are “independent,” the model demonstrates the mutual interdependence between all the classes of people that Adam Smith dubbed the “invisible hand” in The Theory of Moral Sentiments (1759).[7]
Now that we've found how to compute residual income, we must now use this information to formulate a true value estimate for a firm. Like other absolute valuation approaches, the concept of discounting future earnings is put to use in residual income modeling as well. The intrinsic, or fair value, of a company's stock using the residual income approach, can be broken down into its book value and the present values of its expected future residual incomes, as illustrated in the formula below.
Whether you take a “distribution” (aka free-cash-flow) in the form of a dividend, interest payment, capital gain, maturing ladder of a CD, etc, you are still taking the same amount of cash out of your portfolio. Don’t fall for the trap of sub optimizing your overall portfolio’s performance because your chasing some unimportant trait called “income”.
In the summer of 2017, I first reinvested $250,000 into a RealtyShares Domestic Equity Fund. I already had $250,000 invested with them and I liked the projects they were choosing. After spending the rest of the year making low ball offers on SF real estate and losing, I invested another $300,000 in the fund in December 2017. Given 100% of my real estate crowdfunding are equity investments, there is no set monthly dividend. Each of the 12 investments in the fund have different timetables and objectives.  I’m simply estimating that I’ll earn $9,600 for the year.

This is an ideal strategy if you live in an area where real estate prices are too high to realistically invest in, or you don’t want the hassle and expense of traveling all over the country visiting potential properties. Plus, if you are new to single-family real estate investing, letting a place like Roofstock guide you through the process is a great way to get your feet wet.

For example, you can design digital products, like animal clipart or a downloadable wedding poem that could be printed by the customer. Your design could be resold thousands of times without needing to create each item or ship it. Once you create your digital product and list it on a site like Etsy or Ebay, the revenue flows in with little oversight.
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.
There is also an idea that we should work to build a passive income asset and then sit on the beach relaxing for the rest of our lives. The truth is that most people would get extremely bored with this scenario and will be eager to find something to do. That’s why the world’s billionaires continue to work… they love what they do and it stopped being about the money a long time ago.
