Payment of other taxes and liabilities by purchaser; assignment.

(b) Upon payment as specified in § 47-1361(a) or by another purchaser under § 47-1382(c) , the purchaser shall receive a refund of its payment made under this section, with interest as required to be paid by the redeemer or such other purchaser. The purchaser shall receive interest only on the principal tax amount paid and not on the interest or penalties paid. The purchaser is entitled to the refund only if the purchaser’s certificate of sale is not void and the purchaser provides proof satisfactory to the Mayor that the purchaser made the payment.

(c) If the certificate becomes void, a payment credited to the account of the real property under this section shall be nonrefundable.

(d) The Mayor shall prescribe, by regulation, the procedures for making a payment under this section. Notwithstanding any other law, the Mayor may require payment to be made directly to the Office of Tax and Revenue or any other entity, and payment may be held in escrow or applied as designated.

(e) The purchaser shall immediately notify the Mayor, in the manner that the Mayor shall prescribe, of a payment made under this section. If the purchaser fails to notify the Mayor, the Mayor shall not be liable to the purchaser for the amount of the payment.

(f) If the purchaser assigns a certificate of sale in accordance with § 47-1349 , the purchaser shall also assign to the assignee the purchaser’s interest in the payment made under this section. The purchaser shall immediately notify the Mayor of the assignments in the manner that the Mayor may prescribe. Failure of the purchaser to assign the interest at the time the certificate of sale is assigned, or to immediately notify the Mayor of the assignment of the interest, shall invalidate the assignment of the certificate of sale and the assignment of the interest.
