Given the growth in the sharing economy, your junk can start to pay for itself. For example, if you have some awesome vintage furniture inherited from your grandmother sitting in a storage unit, you can rent this out to photographers for their “styled shoots” which are becoming all the rage. If your furniture is more modern but you still can’t bear to get rid of it – perhaps a home stager will be interested.
I've got a $185,000 CD generating 3% interest coming due. Although the return is low, it's guaranteed. The CD gave me the confidence to invest more aggressively in risk over the years. My online interest income has come down since I aggressively deployed some capital at the beginning of the year and again during the February market correction. You'll see these figures in my quarterly investment-income update.
You can provide tuitions to many school or college going students if you are good in a particular subject. Teaching students is also a great way to earn money. This way you can also enhance your knowledge about the subject you were passionate about. You can also go online and register yourself at websites and portals. This way you can maximize your reach.

You may think of a savings account as just that, savings. But it’s actually another form of income as the money in the account will draw interest. And while this interest may be small, it’s still better than $0. Eventually, you can invest this money whenever an opportunity presents itself in order to gain other income streams.  Look into Tax Free Savings Accounts if you are going this route.
Right now we have five, but we’ll probably cut that down to four at ER next year. Current: W-2, business income, rental income, interest on personal loan plus accounts, dividends and cap gains. Future: subtract W-2 for the most part, not counting little “fun work” projects. If we were looking to live the high life, we might aim for the millionaire’s seven sources, but we feel like our four sources will let us live very comfortably with plenty of contingency plans in place. 🙂
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.
