Go back to Erudin and get someone to cast Invisibility on you(if you can't
do it yet) then get close enough to the house to use the /corpse
command(this will not end the invisibility). Continue to use the corpse
command until you are far enough away from your body that you can loot it.
This is how people retrieve their bodies when they are charmed by Meldrath
in the Mino caves.

Hope this helps.

Yours,

PS - If this isn't possible then ask for some older characters to help, most
are willing if you are nice enough.
