Who buys these multi-million dollar properties?

Every time I open The Edge newspaper, I get this wave of envy over the multi-million dollar properties available for sale. They are inevitably large bungalows that are fully renovated with top quality finishings, and with nice views or lands. They also cost more than I’ll ever earn in a lifetime, yet I’m sure there must be people buying them else it won’t be worth the time of the real estate marketing company to advertise it in a paper like The Edge where I’m sure advertising isn’t cheap. For now, I’m looking and drooling and working my way up to buying a large expensive property one day even if its just going to be just me staying in there!
