Different scenario really, yes I'm sure he waited for 35yrs to buy Dairy Bell. But he didn't just sit on his hands for 35yrs and buy nothing, he went into other areas/markets and found other things to buy.
Same goes with realestate - you may not buy the apartment in the CBD now, or for another 5yrs, but does'nt mean you could'nt make good money buying an old house 5kms from the city in the mean time.
There are so many different area/types of RE to buy, to say there will be an overall market crash that will send prices falling so we can then pick up bargains is short sighted. Right now there are areas going down, whilst other areas are booming. It'll be the same in a market crash - not every RE area goes down in a crash, that's where good R&D will serve investors well.
