Clear to Close!?!?

I'm not 100% convinced, but apparently Bank of America has pronounced our buyer's loan clear to close and the "packet" is on it's way to the attorney's office. We're scheduled for a 4:00 closing today. I think I'll fully believe that once everything is signed, but I will call to start arranging the movers and utilities as soon as Scott, our realtor, calls to let us know that the packet is in the hands of the closing attorney's office, and it is in time for the 4:00 closing to happen.
