Since David may never be coming back to this site, If anyone other than David can point me in the right direction, Id greatly appreciate it. I live in Chicago, and I need to buy a quality rental to hold long term somewhere but I have no idea where, and I really don’t want to buy in Chicago. Chicago is insanely corrupt and in HUGE debt. I cant leave Chicago in the near term, I take care of an aging parent, and if I left, my salary would drop by 50%. Id still like to diversify into a rental property.. but I feel that if I just call up a stranger, they’d attempt to sell me their best pig with lipstick, and pressure me to jump on the deal before someone else ‘stole’ it. I have no problem hiring a property inspector from a different city, but don’t want to waste hundreds of dollars if the agent is steering us towards crap property after crap property. I’m looking for broad advice. Any constructive reply appreciated. Thanks guys.

Residual income is money that is earned on a recurring basis, typically as the result of a single original action. Rather than earning an hourly wage, residual income is typically generated through an initial investment of time or money with the goal of earning continuous payments. Once the initial investment, product, or service is made, the ongoing income that is earned is generally passive in nature.
Why did P2P lending get a liquidity ranking of 6? It is quite possibly the most illiquid investment option you listed. You said you rank liquidity by “difficulty level of withdrawing your money without a massive penalty”, and for Lending Club notes, it’s not only difficult and extremely time consuming to sell all of your notes in their super illiquid market, but you would have to sell your notes at large losses to hope to get others interested in buying your notes. On top of that, it is impossible to withdraw your money any other way other than just waiting for interest/principal to pay off every month until maturity in 3 to 5 years. You can’t just one day tell Lending Club “I want to quit, please give me my money back.” One can even argue that it is less difficult to sell a home (in order to “withdraw” the money invested) than to withdraw all of their money from a P2P loan portfolio because it is very possible to sell a home before 3 to 5 years.
Online courses have exploded in the past five years. Experts and creators can now create video courses to teach others their craft. A course can be about anything that people want to learn. Friends of mine have created courses and say the amount of effort is similar to writing a book. But once its done and starts to sell, it’s a solid passive income stream.

Residual income is calculated as net income less a charge for the cost of capital. The charge is known as the equity charge and is calculated as the value of equity capital multiplied by the cost of equity or the required rate of return on equity. Given the opportunity cost of equity, a company can have positive net income but negative residual income.
