All real property of the corporation is exempt from levy and sale by execution, and an execution or other judicial process may not issue against it. A judgment against the corporation may not be a charge or lien upon its real property. However, this section does not limit the right of an obligee to foreclose or otherwise enforce a mortgage of the corporation or to pursue any remedy for the enforcement of a pledge or lien given by the corporation on its rents, fees, or revenues.
