Student lets are usually 1st July to last day June. July and August are often left unoccupied for some of the time by the tenants, even though they may have put their personal belongings there. The tendency by landlords and agents is to charge the tenants half rent for July and August as most of them start to move in sometime in September. However, some agents and landlords write on the contract that the money paid for July and August is a “retainer”. Is there such a thing as a “retainer”? Either the students are the legal occupiers or the landlord is, surely?
