it sounds like it's a bunch of things to stop bad behavior since just telling people not to do it doesn't work
like demolition timer to stop people from rushing houses to flip at exorbitant prices, even a few hours or a day or two of the housing list saying "being demolished" would be enough to make buying a house from another player unworkable
and no more multiple houses, the translation sounds like if you already own multiple they won't be taken away but you won't be able to relocate or buy a new one until you get down to 1/0
fc's have functionality requiring a house to use but markets get flooded by solo so hard that fc's can't get anything so fc's now get priority
they left relocation alone probably because it won't actually consume houses and also make houses available all over the wards for people looking to buy
