6) Always Remember That Everything Is Relative. The best way to determine worthwhile passive income streams is by comparing the likely return (IRR) with the current risk-free rate of return. If I round up, the 10 year bond yield is at 3%. Any new venture should thoroughly beat 3% otherwise you are wasting your efforts since you can earn 3% doing nothing.
We have decided to invest in 2 ETFs, a multi asset allocation ETF (Fixed Inc, alts and div paying equities) and a preferred stock ETF. This will cover almost 45 percent of our deficit. We will be extremely diversified, can access the markets at a very low cost and the investments are liquid. On this pool of $, we have no plans to invade principal unless the investment grows by 20 percent, which we think is unlikely given the characteristics of the investments.

Nonpassive: Businesses in which the taxpayer materially participates. Also, salaries, guaranteed payments, 1099 commission income and portfolio or investment income are deemed to be nonpassive. Portfolio income includes interest income, dividends, royalties, gains and losses on stocks, pensions, lottery winnings, and any other property held for investment
Investing in a business: Another good way to generate passive income is to invest in a business --even a small one -- in return for a percentage of the profits - just like Shark Tank, only smaller. Lending $10,000 to a local business that, for example, is working on a mobile app for Apple phones could lead to a passive income-generated share of the profits when that mobile app starts selling like hot cakes.
Remember, the skills you have are an asset, they are your “unfair advantage.” They are essential to your unique personal brand, and you can start making money online using those skills if you have the right strategy, tactics, and mindset in place. Another way to describe this is your “unfair advantage,” a term I was first introduced to by Lain Ehmann in SPI Podcast Session #37.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
