Thanks for your responses, appreciated. The builder's policy is buyer
has to sign first, then let the attorney review it, incase if the
buyer didn't like any of the clauses, then he can backout with full
amount.

I though this group might help me suggesting what are the things
involve till closing, I wanted to know what are the steps involved. I
apologise for the group, if I made anything wrong here.

Once again, thanks, appreciated.
