I would strongly recommend packing 75% of what you own FIRST. Essentially pack for a long trip in a vacation home that doesn't supply dishes and towels... and then box up ABSOLUTELY EVERYTHING ELSE including most of your furniture (and yes, most of your children's things... they'll be fine... and from a LOT of past experience... not having their usual odds and ends for a few months makes it like xmas when you do unpack).
This has several upsides:
- Less stuff to "case" (aka what you're having anxiety over)
- Easy to paint the walls (needed before you lease your home / required by law in most states, but I don't know about MI), steam clean the carpets, etc.
- Tenants have different furniture and decorating items than you do. Just like in selling a home, you'll get more/better prospective tennants with a "blank slate" for them to imagine their own furniture, pictures, etc in the house. Make sure your own furniture that you aren't packing up immediately is staged
- Makes moving a breeze, because all the "hard" work is already done. All you have to do is rent one truck... move everything in a morning, set them up in the afternoon and then UNPACK THE REST at your leisure over the next several weeks/months.
*** If you have an extensive movie collection make sure you pack that as well. Buy a CD wallet for some of the kid's favorites and you're good to go. As a matter of fact, it was so liberating using a wallet during one move we just bought a couple big wallets... one for our son's, one for educational DVDs... and one for grownup movies. Ditto... pack up as much of your electronics as you can get by without.
