The ten year SPY average annual return has been **12.44%** with dividends reinvested.

So, 150k invested in SPY 10y ago would be 150\*1.1244\^10 = 485k. So yeah, real estate wasn't even as good an investment as stocks.

Don't you need to compare that to renting out real estate then and reinvesting the rent in more real estate?
