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.

You may not think of driving for Uber as a “passive” income strategy, and in many cases, it’s not. What you may not know, however, is that Uber has a feature called “Going my Way” that allows drivers to specify where they are headed and pick up passengers along the way. So why not sign up as an Uber driver and start getting paid for driving where you were already headed anyway?
People who are making a living with residual income typically create a full-time income from more than once source. In this way, if one of their income streams gets cut off, they will manage their others and perhaps even branch out a bit more. A passive recurring income stream doesn’t have to be isolated to one venue. Because it nearly runs itself, you are provided the freedom to test and evaluate other sources of recurring passive income.

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!

Quick story: Remember that $1.18 I found in the couch? Even when that increased to $30 to $50 a day, it still wasn’t enough to live on. So I looked for other options. In August 2008, after people started to know who I was and how I could help them pass the LEED certification exam through my blog, I wrote an ebook. It included all the information I knew about passing this exam, and I sold it on my blog for $19.95.

Remember, a successful business solves people’s problems. At first, you’re going to have to do the legwork and put in the time. But it’s about building something now so you can reap the benefits later, with the help of software, tools, automation, and people you hire. In this way, you can then turn this business that solves people’s problems into something that generates passive income for you!

In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
