Great but a few comments as below
•Price to Rent Ratio (or Yield)
the yield has taken US as a yardstick in which current yield is extremely high after the collapse of the housing bubble.
In malaysia yield is dropping. in fact it is hard to find a property in which rental can cover monthly installment. i would say 5-6% yield is reasonable based on the nett mortgage interest of 4.2%.
•Relative Prices
This is again has taken US as a yardstick. Generally i would have agreed to this but in malaysia property isn't just a normal roof over the head. Lifestyle property with unique selling point has been a great hit. So while i agree to take this relative prices approach, i would still consider premium price to be paid for unique product. Otherwise, there is nothing to judge the price of fernel which has been a great hit.
•Affordability
Totally agree with this. but affordability has also been boosted due to low interest rate in our country. It is not just depend on the GDP/ house price
•Price of new builds
Agree, however information is not available to us.

Gold is a past thing .. like property is a past thing also ..
