That is a nice list of passive income sources. Actually, the most up-to-date list of dividend growth stocks is the list of dividend champions, maintained by Dave Fish. The list of dividend aristocrats is incomplete at best. For example, the dividend champions list has over 100 companies that have managed to increase dividends each year for at least 25 years in a row. The list of dividend aristocrats has no more than 50 – 60.
If you are too risk-averse to engage in stock trading, there’s a much safer option to earn passive income, albeit with much lower margins of return: certificates of deposit or fixed deposits issued by banks. These financial vehicles are similar to mini investments. CDs work very similar to savings accounts with one notable difference. Once you place a deposit, it cannot be withdrawn until the certificate matures. You can obtain these certificates for lump sums of cash that you can allow to mature within time periods like 2 years or 5 years. The advantage of CDs is that they offer higher interest rates than regular savings accounts. You can rest assured that the money will be safe in the bank. A CD earns interest quarterly or annually and all you have to do is just sit back and wait for it to mature.
Do you know of a successful business that needs capital for expansion? If so, you can become something of a small-time angel investor and provide that needed capital. But rather than offering a loan to a business owner, you instead take an equity position in the business. In this way, the business owner will handle the day-to-day operations, while you will act as a silent partner who also participates in the profits of the business.
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
