N.M. Stat. § 5-5-12
The principal of and interest on general obligation bonds herein authorized to be issued, and any prior redemption premium or premiums, shall be payable from the proceeds of general (ad valorem) property taxes levied without limitation as to rate or amount, except to the extent other revenues are made available therefor. The principal of and interest on revenue bonds herein authorized to be issued and any prior redemption premium or premiums shall be payable solely from the gross or net revenues derived from the operation of any project for the acquisition or improvement of which the bonds are issued, including without limiting the generality of the foregoing, revenues of a prior existing project which is improved by the expenditure of the bond proceeds, and revenues of improvements theretofore or thereafter acquired for such project which are not acquired by the expenditure of such bond proceeds, and from revenues and proceeds of any tolls, rates, charges, fees, license taxes, other excise taxes or quasi-excise taxes which the municipality is empowered to fix, levy and collect (but excluding any general (ad valorem) property taxes), or any combination of such revenues and proceeds. Any such revenues or proceeds pledged directly or as additional security for the payment of bonds of any one issue or series which revenues are not exclusively pledged therefor may subsequently be pledged directly or as additional security for the payment of the bonds of one or more issues or series subsequently authorized. If more than one series of bonds shall be issued hereunder payable from the same revenues or proceeds, priority of lien thereof on such revenues shall depend on the provisions of the proceedings authorizing the issuance of such bonds, it being within the discretion of the governing body at the time it authorizes the first such series to provide that subsequent series of bonds payable from such revenues may not be issued, that subsequent series of bonds shall be subordinate as to lien or that subsequent series of bonds shall enjoy parity of lien if such conditions and restrictions as may be specified in such proceedings can be met. All bonds of the same issue or series shall be equally and ratably secured without priority by reason of number, date of maturity, date of bonds, of sale, of execution or of delivery, by a lien on said revenues and proceeds in accordance with the provisions of this act [5-5-1 to 5-5-23, 5-5-25 to 5-5-27 NMSA 1978] and the proceedings authorizing said bonds, except to the extent the proceedings shall otherwise specifically provide. All bonds not issued payable solely from such revenues and proceeds shall be the general obligations of the municipality, and the full faith and credit of the municipality shall be pledged for the payment thereof.
