When you begin to pack your old space, try to clear out one room, or the garage and use that area to place all of your items that will be ready to go on the moving van the day it arrives. Remember, you have already color coded and numbered the boxes by room and importance as you packed so relax.
Make sure you fill all of the boxes completely or you will have damaged goods when you arrived.
Keep a notebook with a page dedicated to each room as well as a page that list your current utility service providers and keep notes as to when you made calls, shutoff, and turn on dates.
Keep a file folder of all of your moving related expenses so come tax time you and your tax preparer can determine if your move was deductible.
