(1) A trustee lending money on the security of any property on which he can lawfully lend shall not be chargeable with breach of trust by reason only of the proportion borne by the amount of the loan to the value of the property at the time when the loan was made, provided that it appears to the court that in making the loan the trustee was acting upon a report as to the value of the property made by a person whom he reasonably believed to be an able practical surveyor or valuer instructed and employed independently of any owner of the property, whether such surveyor or valuer carried on business in the locality where the property is situate or elsewhere, and that the amount of the loan does not exceed two equal third parts of the value of the property as stated in the report, and that the loan was made under the advice of the surveyor or valuer expressed in the report.

(2) A trustee lending money on the security of any leasehold property shall not be chargeable with breach of trust only upon the ground that in making such loan he dispensed either wholly or partly with the production or investigation of the lessor's title.
