actually its not true,the returns on the 2,3 and 4 room flats are the greatest on average over the past 30 years besides landed properties,landed properties are obviously going to do well because of the extremely limited supply of them on this island,while 2,3 and 4 room flats have a strong demand for them regardless of economic conditions even as the population grows richer because theres always a core of the population that needs them,five room flats however are somewhat volatile and condos have the worst performance of all,during a economic crisis or downturn,when theres high layoffs and redundancy,people tend to tighten their belts or those who cannot afford their mortgages will tend to sell their condos and 5 room flats and opt for cheaper alternatives.....this plus the oversupply of condos result in weak market conditions.
