Real estate is the obvious choice if you are going to make money on your money. I personally am not at the point where I can do any of this in a meaningful way BUT my parents are and they now own a couple homes outright and are collecting income from them to power their retirement income. It makes a lot more sense for anyone that has a chunk of cash sitting in the bank and are planning on slowly drawing from it because you technically still have all that money in a property (or multiple properties) and can sell them if you really need the lump sum of cash but you’ll earn great interest payments until you do that.
With sites like Wrapify and StickerRide, you can earn hundreds of dollars each month by simply driving around town. You’ll need to place an advertisement on your car and drive a certain number of miles every month. If you’re already on the road for work, travel, or school, advertising allows you to make extra cash without any extra time commitment.
Owning an investment property can result in both potential appreciation value over the long-term and direct tax benefits of depreciation. However, acquiring an investment property often requires large upfront capital ($100K to several million dollars depending on the type of asset), and lots of hands-on work. Furthermore, as with any investment, investment properties carry the risk of large, unexpected, and costly liabilities, which many investors do not have the experience or time to effectively handle. An investment property also is relatively illiquid—meaning you can sell at any time, but the sale process can often take months and may be unsuccessful.

You can start earning passive income online via revenue sharing thanks to a tactic called affilliate marketing. No, this isn't one of those sketchy "get rich schemes." Affiliate marketing works like this: You, the publisher a.k.a. affiliate, signs up with a business to market its products on your website using banners and/or links within text. If a customer clicks on that content, they'll be taken to the business' own site. And for every one of those clicks that turns into a purchase (an action that's known as a conversion), you'll receive a commission as compensation for your referral.

Let’s say you just decided to sign up for the Chase Sapphire Preferred® card. Once you had the card in hand, you could begin using it for purchases and earning cash back for every swipe. For every dollar you spend on regular purchases, you’ll get 1 percent back in the form of rewards. For dining and travel purchases, on the other hand, you’ll score a smooth 2 percent back.
Wouldn’t it be nice to earn money while not working? That money is called residual, or recurring, income. It's what can happen after you put a lot of time, effort and sometimes money into a job to continue to get paid for the work months or years after it's done. (Salary jobs are part of linear income. This income is directly related to the number of hours you work. If you work 40 hours, you get paid for 40 hours of work.) Once you set up your business to earn residual income, you continue to make money while doing other things – maybe even starting a new business to generate more residual income!

Residual income is the best model for money generation. Once you master and build up one avenue, you can devote your time and money into another avenue. Eventually you start reaping the benefits of multiple residual income avenues. Enabling you to have complete financial and time freedom. I recommend to all people to build these types of asset models as they can greatly improve their life.
