(1) If the debtor fails to pay the debt(s) within a reasonable time after demand and if such action is in the best interests of the United States, we will liquidate security or collateral through the exercise of a power of sale in the security instrument or a non-judicial foreclosure and apply the proceeds to the applicable debt(s).

(2) Collection from other sources, including liquidation of security or collateral, is not a prerequisite to requiring payment by a surety, insurer, or guarantor unless such action is expressly required by statute or contract.

(3) We will give the debtor reasonable notice of the sale and an accounting of any surplus proceeds and will comply with other requirements under law or contract.
