Wondering if anyone knows when is the final closing? just wondering how long would be my occupancy period. I understand the builder has 3 different entities: A, B, C for this project. Would they have different final closing dates?

I just did my PDI today, the unit was super dirty, vent covers are not in place. Wondering if anyone has heard from the builder about the final closing date? I am just wondering how long would be the occupancy period.
