N.J. Stat. § 18A:56-14
All real estate held by the trustees for the support of public schools and all real estate that may be acquired by them under foreclosure proceedings shall be sold, either at private or public sale, at such times and at such prices as will, in the judgment of the board of trustees, be for the best interest of the state. The board may advertise such properties, either at private or public sale, in such manner as it shall determine. The proceeds of the sale shall be paid into the school fund, and shall be invested as other moneys of the fund are invested. The board may lend to the purchaser of any such real estate, one half of the amount of purchase money, the loan to be secured by bond and mortgage on the premises so purchased.
