Watch other people’s kids along with your own. There’s a good chance your friends who work outside of their homes would be thrilled to have an experienced parent watch their children while they are at the office. It can be manageable if your friend in need has only one or two kids. Plus, the new playmates will help keep your children occupied for a few hours. Pay varies widely based on where you live and the ages and number of kids you'll be watching, but babysitters and nannies typically can make up to $10 an hour in small cities and much more – even double that hourly rate – in larger cities.
Skillshare is more of a social learning platform where you can teach real-world skills. The range of skills that you can teach is only limited by your imagination - from board game strategies, garment construction, cooking tutorials, travel hacking, and relationship tips. I even saw a course on how to build a grown man's wardrobe. Creating a class on Skillshare is free. For each student who enrolls, Skillshare takes a 30% fee (Similar to Udemy). You are also provided a unique teacher referral link that lowers the fee to 15% for students who enroll via your referral. Note that all online courses on Skillshare go through an approval process based on specific criteria.
Invest. There are no guarantees when it comes to investing, but you should always start sooner rather than later. If you are looking for a good investing platform, I recommend Motif. Motif Investing allows individuals to invest affordably. This approachable investing platform makes it easy to buy a portfolio of up to 30 stocks, bonds or ETFs for just $9.95 total commission.
Index funds provide you with a way to invest in the stock market that is completely passive. For example, if you invest money in an index fund that is based on the S&P 500 Index, you will be invested in the general market, without having to concern yourself with choosing investments, rebalancing your portfolio, or knowing when to sell or buy individual companies. All that will be handled by the fund which will base the fund portfolio on the makeup of the underlying index.
 @Philip Taylor So by what you’re saying, I can be an unaccredited doctor or surgeon for someone (for example) but do it at a much lower rate than the accredited doctors and surgeons. Since I know what a scalpel is and I wear rubber gloves, I’m a doctor. So, I don’t have to have to respect the profession of medical science at all since I think I know what I’m doing and just go for it.
With Google AdSense, you can earn passive online income from your website by showing ads that are relevant to your visitors. The great thing about Adsense is that Google does most of the hard work i.e., they find the advertisers, pick the ads, track the clicks, and even deposit the earnings straight to your bank account each and every month. No wonder that 65% of the top 200 websites that show ads use AdSense.
Note:  There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and not having impossible standards for cashing out. As always, be careful with your personal information. I recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.

Cafe Press: This website allows you to create digital designs that can then be sold on the platform. You'll earn a commission for everything that sells and you'll never have to deal with logistics like printing, warehousing and customer service. If you have some graphic design skills, then this is a great potential source for your web-based income. 
Alibaba is a Chinese eCommerce store that matches Chinese suppliers with buyers all over the world. Prices are extremely cheap, providing the possibility of large profits. However, with the potential profits comes more risk. As you are dealing with suppliers in China, if the quality of the product that arrives isn’t up to standard there is little that you can do about it.
If you’ve got expertise in a certain area, package up your knowledge into an online course and sell it. This has become a very popular business model for online entrepreneurs over the past several years. The two big websites that are used to sell online courses are Udemy and Teachable. Check out this awesome article by Regina on How to Create an Online Course that Sells.
It’s one of the oldest and most proven ways to make money – buy low, sell high. The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new. In this way, you might be able to acquire an item for $5, and later sell it for $50.
Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited. In general, you cannot sell alcohol, weapons, service contracts, animals or event tickets. Also, while not always prohibited, you may find restrictions on how you can sell items in some categories, such as art, gift cards and coupons.[27] eBay, Craigslist and Amazon publish these guidelines on their websites.
We’ve discussed how to get started building passive income for financial freedom in a previous post. Now I’d like to rank the various passive income streams based on risk, return, and feasibility. The rankings are somewhat subjective, but they are born from my own real life experiences attempting to generate multiple types of passive income sources over the past 16 years.
You can set up a website, gradually build up the content (articles, videos, podcasts, etc.), then eventually monetize the site through advertising, affiliate marketing, or even the direct sale of specific products or services. Even better, you can generally find whatever services and technical assistance you need online and free of charge. Later on, when your site develops a reliable cash flow, you can begin working with paid providers who can take your blog to the next level.
Writing eBooks is an excellent strategy for people who are skilled writers and feel like they could do enough research to learn what is necessary to write a book on some topic.  I wrote my first eBook about photography.  I wasn’t a pro, but I really liked photography and thought I could at least share what I’d learned so far.  It did so well that it is what motivated me to start a blog and work online.

One of the great parts about the online world is that a website and its domain name is like real estate - It can go up in value over time. In fact, sometimes just the domain name without the developed business can be worth quite a lot to some people. Of course, like almost anything mentioned here, the necessary know-how is required. If you’re willing to put some time into it, then you can earn a nice online income. So far I sold 4 domain names with an average price tag of a couple of thousand dollars. Nice income, considering I bought each domain for around $10….If this income stream interests you, check out - It’s one of the best marketplaces I know for selling websites or domain names.
Creating space for banner ads on your website is another way to generate a revenue from adverts. However, for this type of advertising, you will need to contact businesses directly and ask them if they would like to advertise on your website. The upside is that you can charge a set amount, or even a recurring monthly fee, to business to promote their services on your site. Using a WordPress plugin like AdSanity is an effective way to manage this type of advertising.

Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses from their own websites. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.

19. eBay – Of course you can’t read an article about making money online that doesn’t mention eBay. You can start an eBay store and get serious about it or you can just sell some stuff to declutter your home. Either way, I’ve made my fair share from selling on eBay and it’s still a popular way to earn money. If you decide to start an actual eBay store, you’ll want to find a drop-ship business like Doba that will store and ship items straight to your customers so you don’t have to deal with an inventory.
4. Calculate how much passive income you need. It's important to have a passive-income goal — otherwise, it's very easy to lose motivation. A good goal is to try to generate enough passive income to cover basic living expenses such as food, shelter, transportation, and clothing. If your annual expense number is $30,000, divide that figure by your expected rate of return to see how much capital you need to save. Unfortunately, you've got to then multiply the capital amount by 1.25 to 1.5 to account for taxes.
One of the most appealing options, particularly for millennials, would be #12 on your list (create a Blog/Youtube channel). The videos can be about anything that interests you, from your daily makeup routine (with affiliate links to the products you use), recipes (what you eat each day) or as you mention, instructional videos (again with affiliate links to the products you use). Once you gain a large following and viewership, you can earn via Adsense on YouTube.
Salvage and resell. Do you love antiques or have a knack for finding valuables at flea markets or yard sales? If you do, it might be time to consider salvaging items for resale – or even scouting out antiques to sell for a profit. While you’ll need to spend quite a bit of time searching for prospects and spend some money buying upfront, you could easily turn a profit if you know what you’re doing.

To get hired, you fill out an application and take an exam to test your knowledge. “If you pass, you go through a mock session with an experienced tutor who assumes the role of student and evaluates your creativity, empathy and teaching skills,” says Cindy Hamen Farrar, Ph.D., senior director of academic tutoring at Tutor. “We look for people who know their subject matter and who can break it down and communicate effectively.”
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.

Infographics are currently an extremely popular type of media. An infographic showing information or data in an interesting and fun way can help engage an audience and generate numerous likes and shares. As infographics take more time to create than just simply uploading an image, busy website owners are prepared to pay for custom infographics. And don’t worry, an infographic can be created using simple design software such a Canva. So extensive graphic design skills are not necessary, just a creative eye.

“Donating plasma is similar to giving blood. A trained staff member called a phlebotomist puts a sterile needle in your arm vein to draw blood. The blood is then cycled through special, sterile equipment that separates plasma from the other parts of your blood. Your plasma is then collected in a container, while the other parts are safely returned to your body. This process is called plasmapheresis.”
#9 Military pension/VA disability. Obviously requires a lot of front end effort in your 20s and/or 30s depending on length of service however once out and receiving it is totally passive with cost of living adjustment included most years. It has changed somewhat with new “blended retirement” plan but even those not staying past first or second enlistments often will get some VA rating. My wife got it on both ends of her service as the Navy paid for med school and then she was rated by VA after seven years active duty.

Anthony, nice setup! To your question about the rental mortgages, you haven’t said what interest rate you are paying. As a start, if you are paying more than the risk free rate (Treasury bills) which you probably are, then a true apples to apples comparison would be yes, pay off the mortgage. But, if you are comfortable taking more risk, you have other options to invest in which you *hope* will yield you more over the coming years. You also didn’t say whether the rentals generate net income and if so, how much? What is the implied rate of return on the equity you have invested in them? If you pay the mortgages off, you’ll have even more equity tied up, will the extra net income make that worthwhile? Maybe you should use the money to buy more rentals instead, if purchase opportunities still exist in your town. … this is less of an answer than a framework to analyze the decision, hope it is helpful.

Teaching and tutoring English as a second language is a great way to make money online, not to mention open some doors for you to travel the world if you'd like. While full ESL (English as a Second Language) accreditation is recommended, as long as you’re a native speaker and have the ability to teach, there are people in countries such as Hong Kong or the UAE who are willing to pay upwards of $25/hr for you to tutor them English via Skype. Check out Indeed, Learn4Good and for remote english tutoring jobs or sign up on a specialized site like VerbalPlanet or Chegg Tutors.

If you're interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
