First things first, have you arranged for a professional mover? Whilst it may be important to save money, moving everything yourself is a long, tedious job and often leaves you run down and frustrated. Not to mention the risks of getting furniture out of the property without damaging anything. Professional movers are experts in moving and will make your life much less stressful. If you are unsure of any reputable companies, ask your Realtor®, after all they are experts in the housing industry! Next you should think about arranging your packing materials (go sustainable if you can) and getting a dumpster prepared for both ends of the move. Take photos of valuable items and hold on to them yourself instead of packing them away. Complete an inventory list of all household goods and print it out for your reference. Once you start packing, pack household goods into boxes labeled by room. This way you can easily unpack at the other end! Take supplies you'll need on the day of the move, like a few rolls of tape and markers for labeling.
You'll want to check with your insurance company about coverage for the move as well. Next, clean out your closets and garage, and arrange for a cleaning service for a final cleanup. Once they've cleaned, check every inch of your house to make sure it's empty.
