D "The law undoubtedly is that no person can transfer property so as to confer on the transferee a title better than what he possesses. Therefore, any transfer of the property mortga· ged, by the mortgagee must cease, when the mortgage is redeemed. Now, S. 76(a) provides that a mortgagee in possession must manage the property as a ·person of ordiE nary prudence would manage it if it were his own. Though on the language of the statute, this is an obligation cast on the mortgagee, the authorities have held that an agricultural lease created by him would be binding on the mortgagor even though the mortgage has been redeemed, provided it is of such a character that a prudent owner of property would F enter into it in the usual course of management. This being in the nature of an exception, it is for the person who claims the benefit thereof, to strictly establish it."
