We conditioned to ignore price, just use this tiny down and here ya go.

And only a tiny fraction has been through more than one recession.

If someone is going to cry about their ROI% on 1 rental property over a tiny 3 year window, it shows that they have a fundamental lack of understanding of how the rental property business works.When cap rate and ROI estimates are provided,  that is a general indication of the how the average of properties in that asset class will perform over time.At any tiny window with 1 small sample size you can greatly outperform and underperform.
