The first application of residual income, the remaining money after debts are paid each month, is relevant when analyzing a person's financial status or ability to qualify for financing. The second application, the more widely recognized meaning of residual income, is money that is received on an on-going basis for work that is completed once. This form of income allows the recipient to generate revenue that is not based on time limits. Residual income is the foundation for wealth because it offers flexibility in earning and maximizing income. It also allows income to be generated long after the work has been done.
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.
Flynn has created many different products. While his LEED exam is what got him started, he has both earned a commission from selling other people’s products and offered a commission to others who would sell his wares, and also recently created his first software,, after realizing that most online podcast players offered only the basic stop/start/volume features. He hired a development team to create a superior one, which was a success from day 1. “We sold out 250 beta licenses in less than 24 hours, because I was addressing a need but also, I had built up an audience and trust with them … When you build that amount of trust with your audience, whatever you come out with, they will love.”
So as you can see from the above example, using the concept of residual income, although Company X is reporting a profit on its income statement, once its cost of equity is included in relation to its return to shareholders, it is actually economically unprofitable based on the given level of risk. This finding is the primary driver behind the use of the residual income method. A scenario where a company is profitable on an accounting basis, it may still not be a profitable venture from a shareholder's perspective if it cannot generate residual income.

Index funds provide you with a way to invest in the stock market that is completely passive. For example, if you invest money in an index fund that is based on the S&P 500 Index, you will be invested in the general market, without having to concern yourself with choosing investments, rebalancing your portfolio, or knowing when to sell or buy individual companies. All that will be handled by the fund which will base the fund portfolio on the makeup of the underlying index.

“I don’t believe the overnight success exists. There’s a lot of hard work and time involved beforehand,” say Flynn. Angry Birds may have seemed like an overnight success but it was the 52nd game that Rovio created. Flynn says it took him a year or year and a half to build audiences for his most successful sites.

Many people talk about passive income and create the impression that you never have to do anything to keep that income going. The truth is that you will normally have to keep your eye on things if you want it to run smoothly. For example Richard Branson doesn’t run any of the 400+ companies he started but he goes over the numbers each day to make sure they’re performing well and calls the CEO if there are any problems.
