While it sounds like an ideal income stream, there are more specific benefits of residual income. For instance, unlike a salary, someone does not need to remain tied to the same location in order to earn income. He can move halfway around the world and still make the same residual income as he would if he stayed in the same location as his business.
Purchasing a rental property is another common way that individual generate an income stream.  It is very similar to investing, in that you take a sum of money to purchase the property, and the property returns a cash flow – rent.  You do have expenses related to this that are different from investing, such as a mortgage, utilities, property taxes, etc, which all must be taken into consideration when calculating a return on rental property.
The other equation of disequilibrium, if S + T + M < I + G + X in the five sector model the levels of income, expenditure and output will greatly rise causing a boom in economic activity. As the households income increases there will be a higher opportunity to save therefore saving in the financial sector will increase, taxation for the higher threshold will increase and they will be able to spend more on imports. In this case when the leakages increase the situation will be a higher level of equilibrium.
Just like any industry, there is good and not so good. The good part of passive income is that it can lead to multiple streams of revenue. Entrepreneurs understand more income sources means a more stable business and more room to grow. Implementing passive income strategies creates exciting possibilities and opportunities. Passive income sources allow me to have freedom and financial security in my life and business. I can spend my time traveling or writing, knowing that I'm stilling making income.

Though it can take a while to build up enough cash to put a 20% down payment on an investment property (the typical lender minimum), they can snowball fairly quickly. The key here is to correctly project income and expenses in order to calculate cash flow (the free cash you can put in your pocket after all associated property expenses have been paid). However you have to be sure to include the cost of a property manager in your calculations unless you want to manage the property yourself. Even with a property manager, you may be required to make large repair decisions every now and then – so while this is not a 100% passive activity, you are not directly trading your time for money like traditional employment.

One of his favorite tools is Personal Capital, which enables him to manage his finances in just 15-minutes each month. If you sign up and link up an investment account with $1,000+ within 40 days, you get a $20 Amazon gift card. They also offer financial planning, such as a Retirement Planning Tool that can tell you if you're on track to retire when you want. It's free.
My e-product is currently in development, but I think it could reasonably bring in 1/25 of my income in the first year with minimal promotional effort. If it takes off, maybe 1/5 of my income. Building that up so that I could direct all the proceeds to paying down student loans is a great incentive. I need to focus there, but I also have a few other non-traditional digital products in mind. I need to test the market there before expending too much time or energy.
The reading is organized as follows: Section 2 develops the concept of residual income, introduces the use of residual income in valuation, and briefly presents alternative measures used in practice. Section 3 presents the residual income model and illustrates its use in valuing common stock. This section also shows practical applications, including the single-stage (constant-growth) residual income model and a multistage residual income model. Section 4 describes the relative strengths and weaknesses of residual income valuation compared to other valuation methods. Section 5 addresses accounting issues in the use of residual income valuation. The final section summarizes the reading and practice problems conclude.

This is such a fabulous piece. Thank you for your amazing efforts here. I was wondering -any initial thoughts on what one would charge an employer to post a job (for the idea about creating a site to help people with their resumes, etc)? I need to research for sure but was curious if anyone has any ideas on this. I have a background in the corporate world in management and recruiting and have been tossing this idea around for a while but am stuck. Thank you!
Fantastic update and congrats on being over $200k. That is solid! I also like how you have multiple streams and are diversified. The one thing the last downturn taught me was not to have all my eggs in one basket. I’ve been doing my best to build multiple streams of active and passive income myself too. Passive is the preferred choice of course. :)

Think about it.  If you are saving for retirement, you are trying to save enough in investing to generate enough income to replace your primary salary.  Let’s take my friend’s example above: $50,000 a year.  To generate $50,000, you would need to have almost $1,700,000 saved, and be able to generate a 3% cash flow on that money (which is reasonable if invested in dividend paying stocks).

However, with passive income, there is not a direct connection to time involved. Once the original work is completed, the income continues to come in as long as demand for the product or service exists. Each time a song is downloaded, the musician receives money as a passive income. They did not have to record the song again or do additional work for each download, yet they are paid for their original work.
