A Residual income, also commonly referred to as a passive or recurring income, is an income that continues to be generated after the initial effort has been put in. You can now see why it’s considered to be the most lucrative income source, since it doesn’t require you to trade your time for your money the same way a linear income does. So how’s it possible? Well, it’s another point to team internet. Before the internet, passive or residual income was only possible through a few means whereas nowadays, the possibilities of an earning a residual income is far broader. Let’s review the pro’s and con’s of residual income below:
P2P lending started in San Francisco with Lending Club in mid-2000. The idea of peer-to-peer lending is to disintermediate banks and help denied borrowers get loans at potentially lower rates compared to the rates of larger financial institutions. What was once a very nascent industry has now grown into a multi-billion dollar business with full regulation.

Department C has earned $142.5 million residual income as compared to $40 million earned by department P. Residual income allows us to compare the dollar amount of residual income earned by different departments. Since the residual income in both cases is positive, we conclude that both have met the minimum return requirements. However, with residual income is not easy to compare performance.

​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!

Vanguard: Vanguard has a minimum of $50,000 and a fee of 0.3%. Rebalancing is done automatically once every quarter and tax loss harvesting is done on a client-by-client basis. We included Vanguard because clients who invest between $50,000-$500,000 have access to a team of financial advisors. Those with accounts over $500,000 will have a dedicated advisor.
Under throughput analysis, the only factor that matters is the impact of a proposed investment on the ability of a business to increase its total throughput (revenue minus totally variable costs). Under this concept, the main focus is on either enhancing throughput through the bottleneck operation or in reducing operating expenses. This analysis requires a consideration of bottleneck usage by the likely mix of products to be manufactured, and their margins. This is a much more detailed analysis than is contemplated under the more simplistic residual income approach.
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.
Add Leverage (Mortgage) and you greatly increase the ROI especially from the perspective of using Rents (other peoples money) to pay down the mortgage and increase your equity in the property over time. At this point then yes price appreciation is secondary bonus and we have an arguement of how and why Real Estate can be better than Growth Stocks in some scenarios and for some investors.

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.

Residual income can have two different definitions or applications. The first definition, a less common application of residual income, is the money that is left after monthly debts are paid. This calculation is particularly important when a person is seeking financing or a loan based on their income and available money to cover the additional debt. In this scenario, the residual income is calculated by this formula:
