RE or Dollar Cost Averaging

[Andrew Kazakoff]

I read an article that Donald Trump would have made more money dollar cost averaging in the S&P 500 than building his RE empire. Can anyone attest that building a real estate portfolio outperforms dollar cost averaging the famous indexes over the long term? I plan to invest for the next 40 years therefore, at the end of 40 years, with 20K in principal and 10K invested each year, with a 9% return I would end up with 4.3 Million according to the compound interest calculator that I used, with little headache along the way.  I want to make sure that I will end up with the most money at the end of my working career. Which method will make more money? Successful RE investing OR dollar cost averaging in the S&P 500 or Small Cap Index?
