40% in 3 years is 12% annually, which are abnormal returns that won't be sustained long term. It's like saying you went all-in with leverage on ayymd 3 years ago and found a foolproof way to get tendies.

Real estate and stocks are really different markets and no comparison is quite accurate. The only thing that comes close is a cumulative preferred stock since it acts more like an annuity than ayymd. Even if his house appreciated at the national average of approximately 6% yoy, he's still killing it because he has a cash flow stream the entire duration that he holds the property.
