Taking the top spot is the 5-room flats at Bukit Panjang with a whooping 8533% oversubscribed with only 3 units available! Next is Choa Chu Kang.. Surprisingly, the top few spots are estates in the far-flung locations. The most oversubscribed estate nearest to Central is Toa Payoh with 69 applications for 3 units of 5-room and these units have a quantum of >$500k (a seemingly resistance quantum).
Scanning from the bottom, it's also notable that Kallang and Bukit Merah are languishing there. Aren't these the estates with high COVs in the resale market yet they are merely 200-400% oversubscribed. Perhaps these are locations worth an application.
That said, perhaps these applicants are the genuine owners who typically prefer to stay near parents and resistant to high quantum.
