This is one of my favorite "most unheard of" ways to make money - especially for college students. Being a Loan Signing Agent is a great way to earn money in college because you can make $75 to $200 per hour working for yourself on your own schedule. Students can be signing agents and earn extra cash when they want. The best part is you need nothing more than a notary commission (which can often be attained by simply filling out an application)!
Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others. If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.
Similar to investing, peer-to-peer lending is where you loan money to someone else, and they pay you back with interest. The great thing about peer-to-peer lending is that you can lend as little as $25, and your loan will get bundled into a bigger loan for the borrower. Each month, they'll pay you back principal and interest. You can snowball this initial investment into many investments because you get your principal back as well each month. Many lenders earn over 5%-7% on their investments. Check out Lending Club to get started.
Apply for new scholarships and grants. A lot of students think that they are only eligible for funding when they initially apply for admission. This is a mistake! There are often new scholarship opportunities for upperclassmen, though they aren't always widely advertised. You may also be able to apply for external scholarships or grants, which are offered from groups outside of your school.
