Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
Writing an eBook and selling it on your blog can be a great money maker. Your eBook should be directly relevant to your blog’s content so you can sell your book to your existing audience. Creating a recipe eBook for a food blog or an eBook full of training plans to complement your fitness site are just a couple of examples that have the potential to sell.
No one knows your hometown like you do, and you can translate that into cash by leading tours of your city. The website vayable.com allows you to set up and guide tours around a particular cultural experience. If you’re the foremost expert on ghost stories, beer, architecture, or crime (or anything else!) in your town, then you can start leading tours for people who want to hear your stories.
TaskRabbit. Are you willing to get your hands dirty? (Nothing shifty … we're talking, like, weeding somebody's garden.) People come to this site to find those willing to do various tasks for them, such as putting together a bookcase or running an errand for them. Do as many tasks as you want, and this could become quite the part-time (or full-time) job.
Wonder. People come to this site when they need research done. Wonder doesn't just hire anyone, but you can apply, and if they think you have the skills to do research, you'll get access to their dashboard. You can then choose to answer a question – perhaps coming from a business executive or an author writing a book. Researchers report making, on average, $8 to $16 for each detailed answer, although you can make more, so this is probably only a gig for those who really enjoy doing some digging to find an answer, as opposed to someone who just wants to make fast money.
Did you know you can make money simply by owning a car? It's true, thanks to a company called Turo. Turo is a “car sharing marketplace.” Next time you're in a new city and need to rent a car–instead of using an airport car rental, you could use Turo and rent actual people's cars! (Similar to how Airbnb replaces hotels). Turo lets car owners earn money in three ways: local pickup (renting your car from your own driveway); delivering your car to local places; and also by leaving your car somewhere to be picked up (such as at the airport). Earn Money with Turo.
These mega-sites make it easy to set up shop so customers can browse your products, and there's no need to build your own website. Also, you’ll find a built-in search feature so that interested buyers can easily find your online storefront. Plus, you get to use the site's shopping cart. In short, you avoid a lot of the expense and hassle of setting up an independent e-commerce website.
It doesn’t pay much, but if you’re a healthy person and want to make a bit of extra money online, the AchieveMint app will reward you for doing things like walking, tracking your food, or taking health surveys. AchieveMint works by connecting to fitness apps you might already be using like Fitbit, RunKeeper, Healthkit, and MyFitnessPal and then giving you points for certain actions. For every 10,000 points, you earn $10 with no limit on your earnings.
There is no job too small when it comes to earning to save more or pay off debt and a paper route is about as basic of an extra money job as you can get. Yep, people are still buying newspapers these days. Nothing like a nice clean, crisp paper with a good cup of coffee to start your day. This job will likely take up your early morning hours. You can also search for a paper that only comes out once a week if you want to work less. The bottom line is that a paper route is still a valid way to make extra money and I’d be remiss to leave it off this list.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Next, you need to set up and build your YouTube channel. Your YouTube channel is your homebase for all your content. If you already have a Google account for Gmail or Google Drive, then you can use that to log-in to YouTube and start setting up your channel. Pick a username that works for you and is memorable (if you’re using an existing Google account you’ll have to edit your username in Google+).
Last but not least, you can also earn money online by building an online community, although the monetization strategies you can pursue will vary a lot depending on your goals. You can build a community with a blog, for example. You can also build an online forum and charge people for membership. You could even build up a Facebook group and use your influence there to sell and promote products.
