If the proposal here: https://blognomic.com/archive/theres_a_ghoost_loost_aboot_this_hoost does not pass, this proposal does nothing

Add the following type of Ghost

* Remnant of [X]: [X] must be the name of an idle Realtor. Such Ghosts are known as Remnants, and a Remnant of [X] is said to be a Remnant of the idle Realtor whose name is [X]. Effect: None (for now…)

Add the following subrule to “Hauntings” called “Remnants” with the following text

There may only be one Remnant of any given idle Realtor Haunting any house (that is, one across all houses). If there is ever more than one, all such Remnants are removed from the houses they are haunting. Likewise, any Remnant of a previously idle Realtor is immediately removed from the house it is haunting if that Realtor ceases to be idle.

As a weekly action, an idle Realtor who does not have a Remnant may add a Remnant of themselves to start haunting any House. An idle Realtor who does have a Remnant, as the same weekly action, may switch the house their Remnant is haunting to any house.
