An authority shall have power to issue bonds from time to time, in its discretion, for any of its corporate purposes. An authority shall also have power to issue refunding bonds for the purpose of paying or retiring bonds previously issued by it. An authority may issue such types of bonds as it may determine, including bonds on which the principal and interest are payable:

(1) Exclusively from the income and revenues of the housing project financed with the proceeds of such bonds, or with such proceeds together with a grant from the federal government in aid of such project;

(2) Exclusively from the income and revenues of certain designated housing projects whether or not they were financed in whole or in part with the proceeds of such bonds; or

(3) From its revenues generally.

Any of such bonds may be additionally secured by a pledge of any revenues or a mortgage of any housing project or projects or of any other property of the authority.
