It is mainly a sale-time term, added to a flat's price before it is ever sold the first time. For a renter, it rarely appears as its own charge, but it is often the real reason two similar homes in the same building ask different rents, since a higher floor carries the same preference the original charge was built around. When two homes in the same building ask different rents, we check whether the floor, not the home, explains it.
