D-17 Vs B-17 Population

I can’t seem to understand that if D-17 has a good population / % of houses built and its just 3 km away from B-17 - then why B-17 having possession since 2009 has difficulty attracting population considering it has better development standards, better marketing/dealership network and more robust transfer process?

Gohar bhai the answer is simple. D-17 was developed and got possession many years before B-17.

Dear pk1: And any idea, when was D-17 possession given? Like 5 or 10 years?

The land is solid with less dust issue, etc…location is far better…
