A mortgage or trust deed may provide for an assignment to the mortgagee or beneficiary of the interest of the mortgagor or trustor in leases, rents, issues, profits or income from the property covered thereby, whether effective before, upon or after a default under such mortgage or trust deed or any contract secured thereby, and such assignment may be enforced without regard to the adequacy of the security or the solvency of the mortgagor or trustor by any one or more of the following methods:
1. The appointment of a receiver.
2. The mortgagee or beneficiary taking possession of the property, or without the mortgagee or beneficiary taking possession of the property.
3. Collecting such monies directly from the parties obligated for payment.
4. Injunction.
