I also state there is a supply of about 30k units without buyers in the pipeline, that will come on the market over the next few years.
There is also a link provided by him.

Of which he think only 25% of the residents will get a unit. I assume he use EP, S pass and students.
It is a significant error as the verdict is different. In my original post, I think 30 k surplus over a few years …
