53 Pa. Stat. § 27207
Prior to the date of sale, an owner or interested party may petition the treasurer to enter into a written agreement to stay the sale of the property. If the treasurer finds the execution of the agreement to be in the best interests of the taxing bodies, the treasurer may draw up an agreement which will specify the amount due on claims entered against the property; the interest, penalty and costs of the proceeding to date; and a schedule of payments. The agreement may also include a confession of judgment which includes an amount for attorneys' fees. A down payment must be made prior to execution of the agreement. The existence of an agreement shall not stay the accrual of additional penalty and interest on the balance remaining to be paid. So long as the taxpayer or other interested party complies with the agreement, the sale of the property covered by the agreement shall be stayed. In the case of a breach of the agreement by the owner or other interested party, the treasurer, in addition to any other remedy available under this act or under any other law, may give written notice of default by first class mail to the owner or interested party at the address set forth in the agreement and may place the property in the next treasurer's sale.
