The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.

One aspect you might want to add to your scoring is “inflation protection”. At one end, bonds and CDs generally pay a fixed nominal coupon that doesn’t rise with inflation. Stock dividends and Real estate rents (and underlying property value) tend to. Not reallly sure how P2P lending ranks- though I suppose the timeframes are fairly short (1 year or less?) and therefore the interest you receive takes into account the current risk free rate + a premium for your risk. Now that I think about it, P2P lending probably deserves a lower score in the activity column than bonds too (since you probably need to make new loans more often).

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.
1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.

Residual income is different from a salary, or linear income, which is paid out strictly based on the number of hours a person works. Someone who works on a salary is often said to work “paycheck to paycheck.” This is because he pays all of his bills with his first paycheck and then must wait until he gets paid again to have more money. Ideally, someone will work hard building up a business so that he can enjoy the residual income once his goals have been met. Then he can work on additional projects while still earning money from his business.

I've now only got an SF rental condo and a Lake Tahoe vacation rental in my real-estate-rental portfolio. Although I miss my old house, I certainly don't miss paying $23,000 a year in property taxes and another mortgage, and dealing with leaks and managing terrible tenants. I drove by the other day and couldn't believe how much noisier and busier the street was than where I currently live. I wouldn't be comfortable raising my son there.
You’ve probably heard of affiliate marketing before – it’s when you earn a commission by promoting a product. The product you promote online should be something you’re knowledgeable about and that you believe is high quality. Common sense, right? You’d be surprised by how many affiliate marketers forget that principle, but that’s a whole other story.
What I’m doing: I view passive income as funny money to keep myself sane during this long journey. I estimate 2-10 years to get to my goal depending on how active I am. The dollars created are just points one can accumulate. I’ve made passive income goals for each passive income type and check in at least once a year like I am now to make sure I’m on track. Passive income is also carefully managed to minimize tax liability. When you can build a buffer for a buffer, you are then free to take more risks.
The previous blog post in this series noted that income (measured by labor market earnings) appeared to be 33 percent more persistent than wealth. In their Regional Economist article, Gayle and Hincapié also noted that “using one number to summarize the intergenerational persistence of earnings and wealth cannot answer whether such persistence is due to the inability of the poor to escape poverty or the persistence of wealth and income at the top.”
Residual income is the best model for money generation. Once you master and build up one avenue, you can devote your time and money into another avenue. Eventually you start reaping the benefits of multiple residual income avenues. Enabling you to have complete financial and time freedom. I recommend to all people to build these types of asset models as they can greatly improve their life.
