Apartments need Rent

[Jojoya]

Same as any change to any game system, you'd get every reaction in the book for like a week, things'd calm down and life would go on.

And players would stop buying apartments because the main appeal of an apartment - lack of demolition - would no longer exist while they suddenly have a new major disadvantage - rent - that houses lack. They'll just keep saving up that gil for the day they can finally get a house instead.

You're honestly not thinking this through all the way.
