1. Rent Out Your Extra Property.

Thanks to Airbnb, you can rent out your extra home or property or your vacation home when not in use. If you reside in an area where there are a lot of commuters, or in close proximity to a venue that’s hosting a popular event, then consider renting out your garage, parking space, or unused office space. It’s a nice supplemental income without really doing anything except placing an ad.

2. Sell your own information product.

If you’re knowledgeable in a certain area, then you can start creating products, such as eBooks or videos, and selling them on your blog. It may take a lot of work to create and market your products, but once all the leg work is over, you can just set back and collect the proceeds. 

3. Sell your valuables online.

Yard sales are an easy way to make some quick cash, but some of your items will definitely fitch higher prices online. Items like antiques or your old Star Wars collection are better suited on sites like eBay. The same is true for larger items like playhouses or bicycles. Place them on Craigslist or a Facebook page so that buyer can pick them up at your home. Don't bother if you doesn't have any knowledge about it, there are a lot of step by step guide for selling any product on Social Media in the internet that can help you jumpstart you online business.

4. Invest in stocks or shares.

When you invest in stocks you become a stakeholder. That entitles you to a share of their profits. Investing in stocks has been a popular way to earn a passive income for years, and thanks to the internet, it’s easier than ever to research and invest in stocks on your own.

Keep in mind that the stocks you invest in can change throughout the various stages of life. For example, I look for investments that can benefit my daughter, such as a CA529 plan that will go towards her college tuition.

5. Sell physical products.

Just like with a blogging site, there are several ways to earn a passive income by selling physical products. Probably one of the best known ways is by selling your old junk on eBay. But even if you don’t have anything left to sell you can start drop shopping. This is where you sell products for a company on eBay or Amazon and they’ll take care of the rest -- including shipping.

You can also launch your own eCommerce store by using Shopify or any other eCommerce platform. They literally give you everything you need to sell products online from a complete online shop to including buy buttons on your social media channels. 

6. Peer-to-peer lending.

There are companies that have created a new industry where anyone can become a lender. They will then match you with a consumer who either prefers or has trouble securing a loan from a bank. You can earn a higher interest rates on the loans you issued since you’re dealing directly with the borrower.

7. Start a blog.

Perhaps the most popular way to earn a passive income is by launching your own blog. It only takes a couple of minutes to set up and is cheap to start - just purchase your domain name and pay for hosting.

After that, start creating amazing content that people would be interested in reading or sharing. For example, if you’re an accountant that has helped small business owners with their taxes, then that could be your blog. You should need to write a blogging business plan before you start your blog site so that you have a clear vision in mind on what you want to do with your blog site.

Make sure the topics you write about are popular. If you still love your pet rock, I doubt there would be enough people visiting your our site to monetize it. But, you never know.

Once you’ve gained a following, you can start making money from of your blog by:

Earning commissions as an affiliate. This is where you push other people’s products or services on your site. Make sure these products or services are relevant to your blog. For example, that accounting blog could become an affiliate for accounting or invoicing software. Once you find an affiliate partner you’ll be given a unique code so that whenever a visitor clicks that link on your site you’ll earn your commission.

Sell advertising. If your site has the traffic to become an affiliate, then it may also be good enough for advertisers to purchase ads on your site. You may start off small, like making under $20 per ad. But, you may eventually be able to charge triple digits. Again, your site must be quality.

Find sponsors. This is slightly different from just selling ads on your site. Sponsorships may be a one-off piece of sponsored content or permanent logo embedded in your footer.
