A conveyance of the freehold executed in pursuance of the right to acquire on rent to mortgage terms shall conform with Parts I and II of Schedule 6; a grant of a lease so executed shall conform with Parts I and III of that Schedule; and Part IV of that Schedule applies to such a conveyance or lease as it applies to a conveyance or lease executed in pursuance of the right to buy.
The secure tenancy comes to an end on the grant to the tenant of an estate in fee simple, or of a lease, in pursuance of the right to acquire on rent to mortgage terms; and if there is then a sub-tenancy section 139 of the Law of Property Act 1925 (effect of extinguishment of reversion) applies as on a merger or surrender.
