Hi, as I come to know about this project too late, I did not but any unit here.
On the Developer 10% CN and DIBS, my experience with other developer is they do not
add in any new clause to their agreements, as these are standard agreements, too much exposure to modify it.
What my developer did was, it issued a side offer letter and asked me to sign off with condition that
if I pull out, I have to pay the 10% and interest.
What happened was, the 10% bill did not come to me, developer paid (left pocket to right pocket).
No CN issued, for them, I think too risky to issue this CN lah.
I guess this developer will also just paid the 10% and interest after you have signed the side offer letter
with your commitment to pay 10% if you pulled out.
This is my experience with other developer, may not be the same.

Thanks for the sharing. It's useful info. This is my 1st property with DIBS so I'm really no idea on this.
