I'm not actually opposed to creating a housing ward where needed. To be honest there should be a automatic process that opens 1 ward for every 3 that are "full"; those wards should ALWAYS be private homes ONLY to avoid exploitative sub farms and house sales. The wards will not grow infinitely because the servers do have population caps anyways - so if Balmung is filling up it would add supply on BALMUNG as needed.
As for Mateus I just bid on a private with 0 bids.
