First off, go through all closets, cabinets, and storage areas and throw away or give away anything you haven’t used in a year. Be ruthless.
Get several different colors of post-its and a couple of black sharpies at the office supply store. Bright colored post-its are best.
Pack closets first, then the kitchen, then other living areas. Empty your fridge and eat out until you’re done moving.
Label each box on the top AND the side with a colored post-it that corresponds to the room it will go into (pink for master bath, for example). Also label exactly what is in the box and exactly where it should go (stuff for medicine cabinet, sit in bathtub).
Mark boxes with how many people should lift it (one or two).
Mark doorways into each room of new house with corresponding colored post-its. Put post-its on walls where you want furniture to go (dresser here) and label the furniture itself the same way.
Before moving in lay down discarded carpet remnants on pathways in new house – easy cleanup for mud, etc when you’re done.
The last things loaded into the truck will be the first out, so make those things upstairs furniture and boxes or furthest-end-of-the-house furniture and boxes. That way you don’t have to dodge boxes and furniture near the end. Work from top floor to bottom floor, back rooms to front rooms to unload. Make sure you load the truck in reverse order (bottom floor to top floor, front rooms to back rooms).
Twelve people is a reasonable number to have helping you move. That way there’s plenty of help moving heavy stuff and the first things moved in can be unpacked while later stuff is being moved in.
What are your best moving tips? Mine is just not to move unless absolutely necessary.
