This report is biased. No date of report written.
Isn't it very obvious that a big chunk of private buyer are HDB owners who want to speculate?
Since this group is no longer allowed to purchase private without selling off their HDB, it takes away a big chunk of category of buyers.
That leads to reduction in prices since no other category will replace their demand.
Anyway the report is naughty without giving any statistics or evidence.
Best that can be said is that its an opinion piece. Just mentioned 'price going up'. Its doing a disservice to the readers.
