Here's the scenario:

Have about HK$4M to invest at the moment, looking for say 6% yield as income and also for capital growth. Buying a property and renting it out would seem one obvious option, get the rental as income and the value of the property should increase for capital growth. I already have a property in the UK like this but was wondering if there were other/better investment options anyone could suggest.

Long-term investment, basically working towards semi-retirement.
