Calculating Rate of Return/High Yield Return on Investment

[Michael Terry]

When you get a brochure for an asset in Note Investing, and the displayed Rate of Return/High Yield Return on Investment is 6%, 8%, 14%, how is that calculated? I have done research and am seeing different calculations for different types of real estate. I'm just not sure how it applies to Notes specifically.

Is it just a matter of punching in values into the 10bii calculator? Or are there different values and calculations that lead to a specific final calculation and result?  

There are discussions happening amongst my investors comparing the best investment vehicles - mutual funds (7%-10% ROI historically) vs. note investing (6%-14% depending on the asset).

Thanks all! Appreciate the input.
