The relevant rent is an annualised figure based on the highest ascertainable (at the effective date of the transaction) amount of rent payable, and will therefore be £15,000 /18 X 12 = £10,000.
Mae'r rhent perthnasol yn ffigur blynyddol ar sail y swm uchaf mae modd ei ganfod o rent sy’n daladwy (ar y dyddiad y daw’r trafodiad i rym), ac felly bydd yn £15,000/18 X 12 = £10,000.
