I personally find that claim dubious since I don't think there are 150 units available in all of LIC and it takes a non-trivial amount of time to buy a condo. So for 150 to sell in a week that means there must be 300+ in flight which is basically impossible. Plus for a single firm to do that means there must be, what, 5x as many across other firms which comes out to 1500+. I somehow doubt that 20+% of LIC's total condos are in the process of being sold within a few weeks.
