(1) The obligations so authorized by Section 21-41-41 may be issued at any time after the estimated cost of the special improvements shall have been ascertained by the governing authorities of the municipality, and the amount of indebtedness thereby incurred shall not exceed the estimated cost of such special improvements.

(2) Any municipality which determines by resolution to borrow money under the authority of Section 21-41-41 may obtain interim financing in anticipation of such borrowing for one (1) or more of the local improvements authorized by Section 21-41-3 at any time after the estimated cost of each such improvement to be so financed has been ascertained. Such interim financing may be upon such terms and conditions and may bear interest at such rate or rates as are agreed between the municipality and the party advancing the interim funds or the purchaser of the obligations evidencing such indebtedness; provided, however, the maximum rate of interest thereon shall not exceed that established in Section 75-17-101, Mississippi Code of 1972.

(3) Such interim financing shall be secured by and repaid from the proceeds of the permanent financing issued under this chapter and may be further secured by any earnings on the investment of the proceeds of the interim financing.

(4) The final maturity of such interim financing shall not exceed three (3) years after the completion date of any improvement being financed, as certified by the city engineer. Provided, however, that if the governing authorities of the municipality, after a good faith effort, determine by resolution that permanent financing under Section 21-41-41 cannot be obtained, the municipality may renew the interim financing for additional periods of six (6) months until such permanent financing can be obtained. The municipality may enter into agreements with one (1) or more lenders at any time obligating such lenders to provide renewal interim financing upon such terms and conditions as may be agreed by the municipality and the lenders.

(5) The same terms and conditions with respect to the giving of notice, presentation of petitions and holding of an election established in Sections 21-33-307 through 21-33-311, Mississippi Code of 1972, for the issuance of municipal bonds shall apply before a municipality may borrow money under the provisions of this section. Such borrowing shall be authorized by resolution of the governing authorities of the municipality and may be evidenced by a note or notes in negotiable form with coupons or fully-registered form without coupons. The indebtedness incurred hereunder shall not be considered when computing any limitation of indebtedness imposed by law on the municipality.

(6) Such borrowing, whether or not evidenced by a negotiable note or notes, may be placed or sold at public or private sale for such price, in such manner and at such time or times as may be determined by the governing authorities of the municipality. All expenses, premiums and commissions deemed necessary or advantageous in connection with the issuance thereof may be paid by the municipality.

(7) This section, without reference to any other statute, shall be deemed full and complete authority for the borrowing of such interim funds and the issuance of a note or notes to evidence such indebtedness, and shall be construed as an additional and alternative method therefor. None of the present restrictions, requirements, conditions or limitations of law applicable to the issuance or sale of bonds, notes or other obligations by municipalities shall apply to the borrowing of funds hereunder. No proceedings shall be required for the borrowing of such funds other than those provided for and required herein, and all powers necessary to be exercised in order to carry out the provisions hereof are hereby conferred.
