Have you sold your tenants kids to the Russian mafia yet?
"Buying a PPR in Perth right now is ok but wait it out in Sydney and Melbourne"
What!, 'wait it out'? are you suggesting that people stay renters in Sydney and Melb.? Wouldn't that make them losers?
Here is what i think happened in Syd and Melb.
Loose migration policy
Loose taxation policies encouraging speculation
Loose FIRB law enforcement
Loose-mouth spruikers, real estate agents, 'experts'
Loose moral politicians and law makers
and the most influential - Loose credit
Keep watching those migration levels and building commencements slow..
