Flipping assets is nothing new — just turn on HGTV to find countless house-flipping shows. The concept is simple: You buy an underperforming property, make some upgrades, and sell it for more than what you put in. Flipping real estate is no easy venture, though, and investors regularly lose money. The good news is that you can take the concept of flipping and apply it to much simpler fields. One highly lucrative but often overlooked niche is micro e-commerce, where venture capitalists have been realizing 100-300 percent returns.
