I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so.

P2P lending is the practice of loaning money to borrowers who typically don’t qualify for traditional loans. As the lender you have the ability to choose the borrowers and are able to spread your investment amount out to mitigate your risk. The most popular peer to peer lending platform is Lending Club.

Whether you know how to flawlessly apply eye makeup or build a wooden shelving unit, you can create an online course or video for others to follow. Websites like Udemy and Teachable allow you to build a course, such as how to learn a new language or write a cover letter.

In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
