As an inn owner, it would be nice to have some sort of mechanism to allow me to place a "lock" on the door of a room and set a price (daily/weekly/monthly). A prospective tenant looks at the room and decides to rent it. They click the lock and pay the fee (can even pay in advance, like the lot tax system), and they become a Tenant to that room (like the already existing system). They can opt to terminate the lease, and the room becomes freed up for the next tenant. The room is also freed up (their items sent to their bank and they lose Tenant permissions) if they fail to pay the rent on the room in time.
