In any proceedings for the sale of real estate or to subject real estate to the payment of debts, it appears to the court that the real estate cannot be sold for enough to pay off the liens of taxes, levies, and assessments returned delinquent against it, and it further appears that the purchase price offered is adequate and reasonable, such sale shall be confirmed, and the court shall decree the payment and distribution of the proceeds of such sale pro rata to the taxes, levies, and assessments due the Commonwealth or any political subdivision thereof, after having first deducted the cost of such proceedings in court. Such decree shall be certified to the treasurer who has charge of the delinquent tax books, and such treasurer shall cause the lien of such taxes, levies, and assessments to be marked satisfied upon the list of delinquent lands regardless of whether the same shall have been paid in full.
