Hi, I’m an 18yr old who is about to enter college with a substantial amount of federal aid and scholarships but it is nowhere near enough to pay for the full amount. I know that I will be in debt but I need to figure out a way to generate multiple sources of income somehow to let money flow within the 4-6 years I will be in college. When I’m done with schooling I don’t want to be suffocating in my debt so much where I won’t be able to do anything in life.

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.
