(1) mandamus; or
(2) the appointment of a receiver in equity with power to charge and collect rates, rents, or contract payments and to apply the revenues from the hospital project in accordance with the resolution, mortgage, or instruments.
(b) A mortgage to secure hospital project bonds may provide for foreclosure and the sale of the property secured by the mortgage on default in the mortgage payment or the violation of an agreement contained in the mortgage.
