In case no other person bids the amount due, together with penalties and costs, on any lot, the said Collector of Taxes shall bid the amount due, together with penalties and costs, on the same and purchase it for the District.

A bid shall not exceed the estimated market value of the property or the total liability to the District government, whichever is less. Title acquired by the District government pursuant to this subsection shall be deemed to be prima facie evidence of clear title in fee simple.
