Another suggestion for passive income is refinancing your mortgage. Imagine, for example, that you're making monthly mortgage payments of $1,500 now and can reduce that to $1,200 per month by refinancing your home loan at a lower interest rate. That will let you keep $300 in your pocket each month. Of course, refinancing isn't free -- there are closing costs -- and you'll start the clock ticking on a new loan (typically of 15 or 30 years) when you refinance.

For example, you might take photos and have them available for a fee at sites such as shutterstock.com, smugmug.com, 500px.com, or istockphoto.com. Similarly, you can create and upload designs at sites such as zazzle.com and cafepress.com, where people can buy them imprinted on shirts, mugs, and so on. Similarly, you might write an e-book and sell it online, perhaps via Amazon.com's direct publishing service.

As an Instacart personal grocery shopper, you will actually be doing the grocery shopping yourself (so don’t crush anyone’s avocados!). Your compensation depends on several factors, like the average size of your orders and average number of miles driven per trip. You can also get tips in addition to the pay that comes directly from Instacart (most people report an average earnings rate of $15 per hour).
