The book is not bad but it's not that great either. Think of it as an idea book in which you see him mention something and then research it futher. The rambling just becomes too much as you move along to the point where it becomes annoying to read. The tone the author uses is very nonchalant and he doesn't really explain anything. Ideas are just thrown out.
The bottom line is, it’s smart to have multiple income streams no matter who you are. Why? Because the more ways you can earn money without compromising your integrity, the better off you’ll be. And if you’re self-employed, having multiple income streams is almost essential. Not only will you enjoy a higher income, but you won’t go broke if one stream ends out of the blue.

For those willing to take on the task of managing a property, real estate can be a powerful semi-passive income stream due to the combination of rental and principal value appreciation. But to generate passive income from real estate, you either have to rent out a room in your house, rent out your entire house and rent elsewhere (seems counterproductive), or buy a rental property. It’s important to realize that owning your primary residence means you are neutral the real estate market. Renting means you are short the real estate market, and only after buying two or more properties are you actually long real estate.
When most hear the term residual income, they think of excess cash or disposable income. Although that definition is correct in the scope of personal finance, in terms of equity valuation residual income is the income generated by a firm after accounting for the true cost of its capital. You might be asking, "but don't companies already account for their cost of capital in their interest expense?" Yes and no. Interest expense on the income statement only accounts for a firm's cost of its debt, ignoring its cost of equity, such as dividends payouts and other equity costs. Looking at the cost of equity another way, think of it as the shareholders' opportunity cost, or the required rate of return. The residual income model attempts to adjust a firm's future earnings estimates, to compensate for the equity cost and place a more accurate value to a firm. Although the return to equity holders is not a legal requirement like the return to bondholders, in order to attract investors firms must compensate them for the investment risk exposure.

If you happen to be a photography enthusiast, consider selling your photos to stock-image websites like Shutterstock, Alamy, and iStockPhoto. The demand for high quality pictures in commensurate with the competitiveness of this business. So, if you find a niche (such as landscape photography or business photography) and establish yourself as an expert in it on even one site, you can certainly earn a lot of money in your sleep.
Leveraging the internet to create, connect, and sell is something every creative person should attempt to do. The only risk is lost time and a wounded ego. You can start a site like mine for as little as $2.95 a month with Bluehost and go from there. They give you a free domain name for a year. Forget all the add-ons. Not a day goes by that I’m not grateful for my site.
Since David may never be coming back to this site, If anyone other than David can point me in the right direction, Id greatly appreciate it. I live in Chicago, and I need to buy a quality rental to hold long term somewhere but I have no idea where, and I really don’t want to buy in Chicago. Chicago is insanely corrupt and in HUGE debt. I cant leave Chicago in the near term, I take care of an aging parent, and if I left, my salary would drop by 50%. Id still like to diversify into a rental property.. but I feel that if I just call up a stranger, they’d attempt to sell me their best pig with lipstick, and pressure me to jump on the deal before someone else ‘stole’ it. I have no problem hiring a property inspector from a different city, but don’t want to waste hundreds of dollars if the agent is steering us towards crap property after crap property. I’m looking for broad advice. Any constructive reply appreciated. Thanks guys.
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.
