When there is paid out of a guaranty fund any sum on the principal or interest upon local improvement bonds, and/or warrants, or on the purchase of certificates of delinquency, the public utility district, as trustee, for the fund, shall be subrogated to all rights of the owner of the bonds, and/or warrants, any interest coupons, or delinquent assessment installments so paid; and the proceeds thereof, or of the assessment underlying them, shall become a part of the guaranty fund. There shall also be paid into the guaranty fund the interest received from the bank deposits of the fund, as well as any surplus remaining in the local utility district funds guaranteed hereunder, after the payment of all outstanding bonds and/or warrants payable primarily out of such local utility district funds. As among the several issues of bonds and/or warrants guaranteed by the fund, no preference shall exist, but defaulted interest coupons and bonds and/or warrants shall be purchased out of the fund in the order of their presentation.
The commissioners shall prescribe, by resolution, appropriate rules for the guaranty fund consistent herewith. So much of the money of a guaranty fund as is necessary and not required for other purposes hereunder may be used to purchase property at county tax foreclosure sales or from the county after foreclosure in cases where the property is subject to unpaid local improvement assessments securing bonds and/or warrants guaranteed hereunder and such purchase is deemed necessary for the purpose of protecting the guaranty fund. In such cases the funds shall be subrogated to all rights of the district. After so acquiring title to real property, the district may lease or resell and convey it in the same manner that county property may be leased or resold and for such prices and on such terms as may be determined by resolution of the commissioners. All proceeds resulting from such resales shall belong to and be paid into the guaranty fund.
