You also get to see specific details about each loan, including what the borrower is using it for, the state they live in, how long the pay-off period is, what the monthly payments are, and what rate the borrower will pay. It helps you get a better picture of what type of risk you’re exposing yourself to, and you get to take more control over your investment.
P.S. I also fail to understand your fascination with real estate. Granted we’ve had some impressive spikes along the way, especially with once in a life time bubble we just went through. But over the long term (see Case Shiller real estate chart for last 100 years ) real estate tends to just track inflation. Why would you sacrifice stock market returns for a vehicle that historically hasn’t shown a real return?

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.
