O.C.G.A. § 36-42-9 (2019)

(a) Revenue bonds, notes, or other obligations issued by an authority shall be paid solely from the property (including, but not limited to, real property, fixtures, personal property, revenues, or other funds) pledged, mortgaged, conveyed, assigned, hypothecated, or otherwise encumbered to secure or to pay such bonds, notes, or other obligations.

(b) All revenue bonds, notes, and other obligations shall be authorized by resolution of the authority, adopted by a majority vote of the directors of the authority at a regular or special meeting.

(c) Reserved.

(d) Revenue bonds, notes, or other obligations shall bear such date or dates, shall mature at such time or times (not more than 40 years from their respective dates), shall bear interest at such rate or rates (which may be fixed or may fluctuate or otherwise change from time to time), shall be subject to redemption on such terms, and shall contain such other terms, provisions, covenants, assignments, and conditions as the resolution authorizing the issuance of such bonds, notes, or other obligations may permit or provide. The terms, provisions, covenants, assignments, and conditions contained in or provided or permitted by any resolution of the authority authorizing the issuance of such revenue bonds, notes, or other obligations shall bind the directors of the authority then in office and their successors.

(e) The authority shall have power from time to time and whenever it deems it expedient to refund any bonds by the issuance of new bonds, whether or not the bonds to be refunded have matured, and may issue bonds partly to refund bonds then outstanding and partly for any other purpose permitted under this chapter. The refunding bonds may be exchanged for the bonds to be refunded, with such cash adjustments as may be agreed upon, or may be sold and the proceeds applied to the purchase or redemption of the bonds to be refunded.

(f ) There shall be no limitation upon the amount of revenue bonds, notes, or other obligations which any authority may issue. Any limitations with respect to interest rates or any maximum interest rate or rates found in Article 3 of Chapter 82 of this title, the ‘‘Revenue Bond Law,’’ the usury laws of this state, or any other laws of this state shall not apply to revenue bonds, notes, or other obligations of an authority.
