With websites like Ebay and OLX, you can now sell virtually anything on internet to those who are looking for products. So you can do some handicraft or anything else, which can be created at home in extra time and then it can be sold on ebay. Or you can find some local product which others would find awesome, but its not available in other parts of country and then start selling it online for a profit. Even you can look at some products which are selling at huge discount at stores (wholesale market or under clearance sale) and then sell it on amazon at regular price.
Building a smartphone or tablet app requires a fair amount of technical expertise, but it can pay off handsomely if successful. It doesn't have to be particularly complex or chock-full of features either; a simple one that solves a problem or is entertaining enough to attract users works fine. You never know what may suddenly become popular. For example, the minimalist game Flappy Bird was such a craze that at one point its developer was earning $50,000 dollars a day through in-app advertising. Of course, expecting a success like that is foolhardy, but one can always hope.
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.
However, I think for those who are willing to do what it takes, the sky is the absolute limit. As an example, I’m trying to take a page out of FinancialSamauri’s book and create an online personal finance and investing blog. It is an enormous undertaking, and as a new blogger, there is a seemingly endless amount of work to be done. That said, I hope that one day I can not only generate some passive income from the hours of work I have put and will put into the project, but I hope to be able to help OTHERS reach their financial goals.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth. Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices. In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
