Buying Attitude Index - Q4 2017

Why this index?
In Singapore, there is no official buyer-driven (not developer-driven) index to show Buyers' Attitude for residential properties. This forum is the best place to fill in that gap.

How does it work?
Everyone is entitled for one vote, the index is calculated by:
the percentage of bulls - percentage of bears
(Please vote even if you are neutral because it will change the overall percentage scores).

(The max of the index is 100, the minimum of the index is -100)

On one hand, the global financial markets are at high risk for a correction; on the other hand, Singapore property prices relative to other major cities are relatively inexpensive.
Is it a good time to buy?

Thanks,
