7 C.F.R. § 5001.511
(a) General. A holder can make written demand on either the lender or the Agency to repurchase the unpaid guarantee portion of the loan when the borrower is in monetary default or when the lender has failed to pay the holder its pro-rata share of any payment made by the borrower within 30 days of the lender's receipt thereof from the borrower. When making written demand on the lender, the holder must concurrently send a copy of the demand letter to the Agency.
(b) Repurchase by lender. If the lender, borrower, and holder are unable to agree to restructuring of loan repayment, interest rate, or loan terms to resolve any loan problem or resolve any default, and repurchase of the guaranteed portion of the loan is necessary to adequately service the loan, the holder must sell the guaranteed portion of the loan to the lender. The sale must be for an amount equal to the unpaid principal and accrued Interest, in accordance with § 5001.450(c) of this part, on such portion less the lender's servicing fee.
(c) Agency repurchase. A holder can submit a written demand to the Agency for repurchase only if the lender declines to repurchase. If a prior written demand was not made upon the lender, the Agency will notify the lender and allow up to seven calendar days for the lender to exercise their option to repurchase as provided in this section.
(2) Written demand content. The holder must include in its written demand to the Agency:
(3) Payment. Unless otherwise agreed upon, payment will not be later than 30 calendar days from the date of demand.
