On or before the maturity of such bond the sheriff or other officer who made the sale shall withdraw the bond from the clerk’s office, leaving his receipt therefor and an attested copy thereof, and collect the same. So soon as the purchase money has been paid, the sheriff or other principal officer, or the deputy who acted in making the sale, shall, as commissioner, and in the name of the Commonwealth, convey the land to the purchaser by deed executed at his costs, reciting the execution, the sale and the price of the land. Such deed shall pass to the purchaser all the interest which the party against whom the execution issued had in the land at the date of the judgment or decree. Out of the money so collected the sheriff or officer who made the sale shall pay all costs attending such execution and sale, the costs of a survey, if there was one, all delinquent and unpaid taxes and levies on such land and the debt due the Commonwealth, and the residue, if any, he shall pay to the judgment debtor.
