ORS § 86.010
A mortgage of real property is not a conveyance so as to enable the owner of the mortgage to recover possession of the property without a foreclosure and sale. This section is not intended as a limitation upon the right of the owner of real property to mortgage or pledge the rents and profits thereof, nor as prohibiting the mortgagee or pledgee of such rents and profits, or any trustee under a mortgage or trust deed from entering into possession of any real property, other than farmlands or the homestead of the mortgagor or successor in interest, for the purpose of operating the same and collecting the rents and profits thereof for application in accordance with the provisions of the mortgage or trust deed or other instrument creating the lien, nor as any limitation upon the power of a court of equity to appoint a receiver to take charge of the property and collect the rents and profits thereof.
