To create residual income, you need to create something that people will continue to buy on a regular basis long after you’ve created it. A house is a prime example of this as people will continue to pay rent for the right to live in the house. A business needs to have products that are sold over and over again rather than trading the business owner’s time for money.
1. In-post reviews and recommendations: This is often the first passive income opportunity that comes to mind. You write a review about a product or service you love and hope your readers decide they need that too. You probably have the opportunity to recommend at least one relevant product within most of your posts. For example, when you are sharing your favorite pressure cooker dinner recipe you can also include an affiliate link to the pressure cooker you use.

I own several rental properties in the mid west and I live in CA. I have never even seen them in person. With good property management in place (not easy to find but possible) it is definitely possible to own cash flowing properties across the country. Not for everyone and not without it’s drawbacks, but it seems to be working for me so far. I’m happy to answer any questions about my experience with this type of investing.
Return on investment is not the same as profit margin. ROI looks at the revenue invested in the company and the returns gained or lost on that investment based on the department's net profit. ROI can be used to evaluate the functionality of a company's pricing policies, inventory management and investment in capital assets. ROI is also a useful metric when a company must make a decision about major asset purchases, project funding and changes in the investment portfolio.
The problem with MLM or network marketing is the “dream”. Recruiters sell you a dream, residual income without work, easy money, every thing that breaths will buy the product or service, you don’t have to sell anything: only change brands (instead of buying your traditional Colgate toothpaste buy the USANA toothpaste, even if it is $5.oo more expensive), Everybody is your prospect, lead. Cold selling, recruiting your family, friends, neighbors, coworkers.
Many people talk about passive income and create the impression that you never have to do anything to keep that income going. The truth is that you will normally have to keep your eye on things if you want it to run smoothly. For example Richard Branson doesn’t run any of the 400+ companies he started but he goes over the numbers each day to make sure they’re performing well and calls the CEO if there are any problems.
