The court shall appoint the receiver on a showing that default has been made in any of the conditions of the mortgage, without any further evidence and without regard to the solvency or insolvency of the person liable for the debt secured by the mortgage. The appointment shall be made without notice on a showing to the court that the danger of termination or forfeiture of the leasehold estate covered by the mortgage is imminent or that waste of the same is being committed, or that the owner of the leasehold cannot be found within the state. The mortgagee may be appointed receiver in the discretion of the court.
