You don't mean receivership, you mean a rent receiver will be appointed. He will collect the rent. He will pay himself and he'll pay some of the mortgage and this could go on for a very very long time and cost you a lot of money.
I don't understand why you don't go with the Pip's suggestion.
(The tenant's do not realise in all probability that the Receiver is not obliged to repay them the deposit and the Receiver will leave them in blissful ignorance of that, so if the tenant's are leaving for whatever reason, they shouldn't pay the last months rent.)
