In expensive cities like San Francisco and New York City, net rental yields can fall as low as 2%. This is a sign that there is a lot of liquidity buying property for property appreciation, and not so much for income generation. This is a riskier proposition than buying property based on rental income. In inexpensive cities, such as those in the Midwest, net rental yields can easily be in the range of 8% – 12%, although appreciation may be slower.

India's gross national income per capita had experienced high growth rates since 2002. It tripled from ₹19,040 in 2002–03 to ₹53,331 in 2010–11, averaging 13.7% growth each of these eight years, with peak growth of 15.6% in 2010–11.[328] However growth in the inflation-adjusted per-capita income of the nation slowed to 5.6% in 2010–11, down from 6.4% in the previous year. These consumption levels are on an individual basis.[329] The average family income in India was $6,671 per household in 2011.[330]

This is how the people who are in the 20% and 30% tax bracket can generate another stream of income by investing in accrual funds: The investor will invest in the fund and subsequently should also set up a systematic withdrawal plan (SWP) for the same scheme. The SWP will be set up in such a way that only the gains from the fund are transferred to the investor's bank account, at regular intervals, while the principal remains untouched. So in effect the investor enjoys a steady flow of regular income, but pays lower tax compared to if he had invested in bank fixed deposits. This is because as per tax rules, only the gains are taxed. While investing in accrual funds, the investment option should be growth and not dividend, financial planner and investors say.
I truly believe generating $10,000 a year online can be done by anybody who is willing to dedicate at least two years to their online endeavors. Here is a snapshot of what a real blogger makes through his website and because of his website. Roughly $150,000 a year is semi-passive income followed by another $186,000 a year in active income found through his site. Check out my guide on how to start your own blog here.
I agree that it is important to establish multiple sources of income, but I would be hesitant to group dividend stocks and real estate into the “multiple streams” bucket. Those are investments, and living off of investment income because you are in an emergency state is not a good plan. Cash flow from investments ebbs and flows more than the cash flow from a day job.
If you have a blog or other type of site, you can build affiliate links to different services on the website. Many people use Amazon as an affiliate partner. For example, if you are a beauty blogger writing about different products, you can set up Amazon affiliate links on your blog so that whenever someone buys the product you mention on Amazon, you receive a percentage of the sale. Amazon is not the only affiliate partner out there. Here is good, in-depth information on affiliate marketing. 
Stocks (shares) paying dividends are typically a reliable source of income but they have higher risk of capital losses than cash and bonds. So, it’s wise not to chase yield indiscriminately.  The 10 highest yielding stocks on the ASX 200 (the 200 largest companies in Australia) are shown in the table below.  But their share price performance on average over the last year has been underwhelming, as shown in the far right column:
