Close out safety deposit box if you have one.
Buy a bunch of ziplock bags -- these will come in handy when packing large sets of small items, like silverware, or for components of furniture that need to be broken down (i.e., screws, bolts).
Make copies of any important documents before mailing or hand-carrying them to your new address.
Remove wall accessories such as drapery rods, small appliances, food and utensil racks.

Dispose of flammables such as fireworks, cleaning fluids, matches, acids, chemistry sets, aerosal cans, ammunition, oil, paint and thinners.
Refillable tanks must be purged and sealed by a local propane gas dealer. Discard nonrefillable tanks. Some carriers and the military do not permit shipment of any propane tanks.
Disassemble outdoor play equipment and structures such as utility sheds.
Disassemble electronic components such as stereos and VCRs. Place original packing boxes (if they are in good condition and you want the movers to use them) by the equipment. If you decide to pack the item in the original carton yourself, leave the boxes opened so items can be inventoried.
If you have a computer, "park" hard disk drive units, then disconnect computer systems. Place floppy disks in protective cases before packing into cartons.
If you are using your vehicle, make sure that it is in good running condition and that all required maintenance has been completed.
Give a close friend or relative your travel route and schedule so you may be reached if needed.
