Well, in CAGR terms it's only 11.61% per annum and you would have been better off just buying an ETF (SPY returned 12.35% last decade) and you would have made more money with less headache. And this is NOT including stamp fee, fixes, issues, potential legal and regulation changes. Not to mention that most properties did not triple in value in the last decade, in some markets property even went down. If you bought in Dubai in 2007-2008 you are still -50% underwater. And not including the illiquidity of it, exposure to a single market and a single area and countless other risks.
