Notice under clauses (A) and (B) of this paragraph shall be mailed at least twenty-one days prior to the date of foreclosure sale, and shall be mailed to the owner or mortgagor at the address stated in the mortgage agreement, or, if none, to the address of the security property, or, at the discretion of the foreclosure commissioner, to any other address believed to be that of such owner or mortgagor. Notice under clause (C) of this paragraph shall be mailed at least ten days prior to the date of foreclosure sale, and shall be mailed to each such lienholders address as stated of record or, at the discretion of the foreclosure commissioner, to any other address believed to be that of such lienholder. Notice by mail pursuant to this subsection or section 3707 (b) of this title shall be deemed duly given upon mailing, whether or not received by the addressee and whether or not a return receipt is received or the letter is returned.
Any surplus after payment of the foregoing shall be paid to holders of liens recorded after the mortgage and then to the appropriate mortgagor. If the person to whom such surplus is to be paid cannot be located, or if the surplus available is insufficient to pay all claimants and the claimants cannot agree on the allocation of the surplus, or if any person claiming an interest in the mortgage proceeds does not agree that some or all of the sale proceeds should be paid to a claimant as provided in this section, that part of the sale proceeds in question may be deposited by the foreclosure commissioner with an appropriate official or court authorized under law to receive disputed funds in such circumstances. If such a procedure for the deposit of disputed funds is not available, and the foreclosure commissioner files a bill of interpleader or is sued as a stakeholder to determine entitlement to such funds, the foreclosure commissioners necessary costs in taking or defending such action shall be deductible from the disputed funds.
