Wow... that's an unfortunate thing that can happen =/.

What size of personal house did you own beforehand? You could relocate your personal one to a different plot and have some other member relocate your FC house closely afterwards(correct me if I'm wrong, but I believe those random timers are only for new purchases, and don't count for relocations). It's going to be costly, though not impossible to achieve, depending on your old personal house's size. Considering Gil is an issue, maybe it's more of a long-term goal though =/. I cannot think of any different solution.

In the end it's going to feel bad anyways though >.<.
