What is your best ROI? Desired ROI?

[JD Randall]

What is your highest ROI (return on investment) and what is your desired/expected ROI?

From my understanding inflation is taking away 2-3% of purchasing power a year. High-interest savings accounts interest (ROI) is .75%-1.25%, very conservative investments are about 4%, the stock market averages 6-7% and Real Estate is the outlier with ROI being everything from 12% to infinity (no money down investments). Is this accurate?

If you do BRRRR I would also like to know how much of your own money you used to do the deal because although you may not leave the money in the deal, you still used that money to set the investment up.

Hopefully I picked the right forum category to post to.
