Moving
Book the truck after the date is real, and label boxes by room.

Book the move after the closing date is real
Wait for a contract date, then book the truck with a written backup plan.
Label boxes by the room they go to
Name the room on two sides of every box and keep a first-night box with you.
Measure doors before you book a truck
Measure the sofa, the mattress, and the narrowest doorway before you reserve a truck.
Pack a first-week kitchen box
Fill one box with the pan, mugs, soap, and towels you will want before the rest is unpacked.
Forward the mail before you leave
File the mail forward in time for it to start on your possession date.
Photograph the empty rooms on the last day
Take a photo of each empty room, plus the meter readings, before you lock the door.
Carry the closing papers with you
Keep the signed settlement set in your car, not in a box on the truck.
