A good portion of my stock allocation is in growth stocks and structured notes that pay no dividends. The dividend income that comes from stocks is primarily from S&P 500 index exchange-traded funds. Although this is a passive-income report, as I'm still relatively young I'm more interested in building a large financial nut through principal appreciation rather than through dividend investing. As an entrepreneur, I can't help but have a growth mindset.
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
