House prices at any point in time, like that of any other asset with a built in cycle, depends largely on irrational sentiment and emotion. Fundamentals only tell you what the price OUGHT TO BE, not what the price WILL BE at any given point in time. Fundamentals in the US were largely constant, but the price for certain houses fell as much as 70% during the crash, way below the cost price of the house, and way lower than the fundamentals would indicate. Sentiment is a fickle b*tch, both on the way up, and on the way down.
What we are seeing in Malaysia is a newfound positive public sentiment towards purchasing housing at the highest possible end of affordability, and this is encouraged by prolonged historically low interest rates and a sustained period of consistent outsized gains, which has led to, rightly or wrongly, a perception among many ordinary Malaysians of reduced/zero risk, guaranteed outsized returns and a fear of being priced out in the future. How many Malaysians who hold millions worth of property and mortgage debt are invested in other asset classes? So long as this sentiment lasts, many ordinary Malaysians will continue to bet their next 35 years of earnings on houses which they can barely afford, fundamentals be damned.
Again though, sentiment is fickle, and I think there is a relative lack of sophistication in the average Malaysian investor who tends to decide based on limited anecdotal experience instead of statistics and dispassionate macro analysis. Such investors are just as quickly inclined towards fear on the way down as they are to greed on the way up.
I have a theory that the mentality of those who disregard macro analysis is analagous to the mentality of those going to a casino, or those buying lottery tickets. Let me elaborate.
Statistical data and mathematical analysis necessarily lead to the conclusion that an average person who gambles at a casino is more likely to lose money than gain. Logically therefore, nobody in their right mind should go to a casino. However, there are necessarily people who have had personal experience winning money, and due to the logical fallacy called hasty generalisation, they will tell you that your theory is wrong based on their own limited experience. (i.e. I have won the last 5 times, and my friend has won the last 5 times, and his friend has won the last 5 times, and therefore I believe I will continue to win) There are those who read, understood and agree with your data will tell you that they are exceptionally skilled or lucky (i.e. I am different, I am special, your theory does not apply to me). Ultimately though, regardless of all the theorizing and discussion the casinos are still packed with very wealthy and educated people, and the casino owner laughs all the way to the bank.
Caveat: Macro analysis at the layman level at least will not help you predict the future, and any prediction made by experts with any degree of specificity is usually wrong. Asset markets are inherently unpredictable, and the rules of the game may change at any time with a simple announcement of a new government policy, whether here, China, the US or elsewhere. Nonetheless, my analysis leads me to the conclusion that based on current conditions, people, especially the overleveraged, should start diversifying away (not exiting completely of course) from the property market which is looking increasingly vulnerable.
