You can easily make money online now through freelancing. Since you’re trading time for money, your focus will be on finding a few quality clients who pay you well. However, if you’re just starting out, you might need to take on a lot of clients who pay you less to build your portfolio. Freelancing gigs can be diverse making it one of those money making ideas almost anyone can do. Graphic design, programming, consulting, and accounting are a few examples of the types of roles you can do as a freelancer.
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.
