Peerstreet – This residual income option is slightly different, helping you earn money using real estate backed loans instead of the property itself. By helping fund the loan, you’ll earn a percentage of the interest rate charged to the borrower. Most loans are short-term, generally lasting between 6 and 24 months. You can build your own portfolio by choosing the exact loans you’d like to fund, or Peerstreet will choose the loans for you. Again, you need to be an accredited investor, although the minimum investment here is just $1,000.

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.
