None of the above works as all these builders have strong back up legal pundits and they work round the clock in making the agreements fool proof in the favor of builders. Further if u start reviewing and challenging the different clauses the builder has his prerogative not to enter deal with u. Further the current situation is such that any project is launched the 100% gets sold out is 24 to 48 hrs. Where is the time and opportunity for you to review and challenge and protect our interest? India is booming. So middle class buyers have no say or role to play.
