The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software. If you’ve done everything right, your software will be accepted to the Apple and Google Stores and you’ll make money every time someone downloads it or pays for a premium feature.
Which all goes back to my point – since companies change in a lot of unpredictable ways, it makes more sense for passive income to just ride the market by investing in a Total Domestic Stock Market, Total Bond Market, and Total International index funds, with allocations that depend on your goals and time horizon. For income, withdraw 4% or less, depending on what research you believe, and you’ve got a pretty low risk strategy.

In expensive cities like San Francisco and New York City, net rental yields can fall as low as 2%. This is a sign that there is a lot of liquidity buying property for property appreciation, and not so much for income generation. This is a riskier proposition than buying property based on rental income. In inexpensive cities, such as those in the Midwest, net rental yields can easily be in the range of 8% – 12%, although appreciation may be slower.
Stock dividends: Some stocks, especially stocks from big corporate standouts, pay dividends to shareholders based on the number of shares they own, and the percentage of the stock price on the dividend date. For example, if a company pays out 3% on a stock that's trading at $100 per share, you'll earn $3 for every share of that stock you own. Add it up and that can be good take-home pay as a passive investment.
If you are a creative type, then you could make money online by designing and selling crafty products on Etsy. Etsy sells a range of beautiful and original items from independent suppliers. Categories range from jewelry, clothes, and accessories, to art, collectibles, and vintage. So if you have some stunning crafty creations, Etsy is the perfect platform from which to sell from.
One way that people have been earning money online recently is going to your local stores and hitting the clearance section.  Buy up a shopping cart full of stuff and then mail it to Amazon FBA (fulfilled by Amazon).  Amazon then sells the items and mails them for you, and pays you your cut.  There is even a really cool app for your phone that you can use in the store to scan the barcode and see how much money you could make selling it on Amazon, even including your shipping costs.

Equally, you can charge businesses to ‘claim’ their listing, a method used by many large directory sites like Google Business and Yelp. This involves companies paying to upgrade their listing and adding information such as their web address, social media links, images, and more. Other revenue streams include charging for ad space, adding affiliate links and even charging for services and products on your directory site.
Online savings accounts usually come with crazy good interest rates to help you grow your money faster (regular in-person banks can’t offer rates as high). We’re fans of CIT Bank and Discover Bank (among others) because their interest rates are often over 25 times the national average. That means the money in your savings account will grow 25 times faster than the pace it’s most likely growing at now. Really, though, you can’t go wrong with pretty much any online savings account that offers over 1.50% APY 🙂
