re: sydney/tokyo property price match My parents sold their house (in Leichhardt) in the early 80's for less than 100,000 $$$.
Last year I went to see some friends who live next door.....the same house was sold few months before I visited them, for 900,000 $$$!!!!!
Incredible.....How can someone on 50-70,000 a year afford to buy a house in Sydney???
