Start where it's easy
Begin with storage areas like the garage and closets. Sort into keep, donate, sell and haul away.
Use the one-year rule
If you haven't used it in a year and it isn't sentimental, it probably doesn't need to move.
Schedule the haul early
Book junk removal a few days before movers so the truck only takes what you're keeping.
