53 Pa. Stat. § 7283a
If with regard to two or more properties a municipality is authorized under section 31, 31.1 or 31.2 to petition the court for the individual sale of each property, free and clear of its respective claims, liens, mortgages, charges and estates, the municipality may join any number of the properties in a single petition, and the court may grant a rule upon all parties shown to be interested in any of the properties to appear and show cause why a decree should not be made that the properties which are the subject of the petition be sold together in one sale, free and clear of their respective claims, mortgages, charges and estates. If upon a hearing thereafter the court is satisfied that service has been made of the rule upon the parties in the manner provided in section 39.2 and that the facts stated in the petition be true, the court shall order and decree, subject to any applicable restrictions and limitations in section 31, 31.1 or 31.2, that the properties be sold together at one sale at a subsequent sheriff's sale day, to be fixed by the court without further advertisement, clear of all claims, liens, mortgages, charges and estates, to the highest bidder at such sale. If a judicial sale of multiple properties is ordered, any party shown to be interested in a particular property may, at any time before the sale, pay the municipality the whole of its claim relating to the particular property, with interest, costs, charges, expenses, fees and attorney fees, whereupon the proceedings on petition with regard to that property shall at once determine. A judicial sale of multiple properties shall not diminish the right of redemption with regard to any particular property that is a part of the sale.
