(a) The bureau shall schedule the date of the sale no earlier than the second Monday of September and before October 1, and the sale may be adjourned, readjourned or continued. No additional notice of sale is required when the sale is adjourned, readjourned or continued if the sale is held by the end of the calendar year. The bureau may, for convenience and because of the number of properties involved, schedule sales of property in various taxing districts or wards on different dates. Except as otherwise provided in this article, all sales shall be held by the bureau by the end of the calendar year.

(b) No property shall be exposed to sale where the delinquent taxes involved in a claim are being paid by the owner under any law abating penalties, interests and costs, or either, unless there has been a default by the owner in payment, in which case the sale of the property shall be proceeded with, as herein provided, at the time fixed for the next scheduled sale, occurring at least ninety (90) days after such default.

(c) The taxing authorities of the county and of any political subdivision in the county may jointly petition the court of common pleas of the county to stay the sale of property in any political subdivision held under the provisions of this section. The petition shall set forth the reasons for such stay. If, in the opinion of the court, after hearing, there are sufficient reasons for such stay, the court shall have jurisdiction and power to enter an order staying such sale for any period not exceeding one year from the time fixed for such sale under subsection (a) of this section. In case of any such stay of sale, the properties in such political subdivision shall be sold in accordance with the provisions of this section on the date of the next annual sale.

(d) No individual whose landlord license has been revoked in a municipality pursuant to its ordinance may purchase property in the county in which the local municipality is located at a tax sale under this act. Pursuant to this subsection, a municipality shall furnish to the county in which such municipality is located, within forty-eight (48) hours in advance of a tax sale, documentation relating to landlord license revocations pursuant to municipal ordinance.

(e) Any municipality that issues landlords' licenses must provide to a landlord, prior to revoking such license, notice of the potential revocation. The landlord licensing ordinance must provide the landlord a reasonable opportunity to respond to the notice and an opportunity to appeal any decision made against him. If the landlord is in violation of a local ordinance that deals with building standards, safety or property maintenance, the municipality must also provide the landlord with a reasonable opportunity to comply with the ordinance prior to revocation. A revocation of a landlord's license shall not be permanent. The revocation shall only be until the landlord has corrected the code violations that led to the revocation. However, the landlord's license shall only be reinstated after the building has been inspected and approved by the appropriate official or employe of the licensing municipality. Inspections for reinstatement shall be performed within a reasonable amount of time after the landlord notifies the municipality of any corrected violation. The municipality shall, by ordinance, establish procedures to implement this subsection. Any municipality whose landlord licensing ordinance is contrary to this subsection must revise the ordinance within sixty (60) days of the effective date of this subsection. The notice, response and appeal provisions under this subsection as well as the prohibition on bidding under subsection (d) shall only apply to actions on or after the effective date of this subsection.
