birth of Act 93...I found this on Rep. Parker's web site. It gives insight into the intention of lawmakers.

"Representative Parker will be introducing a bill to provide the City of Philadelphia with additional authority to collect delinquent property taxes.

Philadelphia needs additional tools to effectively collect delinquent property taxes from speculators who own vacant, blighted tax delinquent properties and from investors who purchase and rent properties and fail to pay their property taxes. An analysis of delinquent property taxes shows that many non-residents own ten, twenty or more properties that are tax delinquent, vacant or abandoned. Non-resident investors own rental properties that not only have code violations but are delinquent in paying their property taxes.

Simply putting a lien on the specific property that is delinquent has not been sufficient to cause payments to be made. The City needs the lien to be placed against all of the property owners’ real estate located within the Commonwealth. Then, when the property owner attempts to sell any of his/her property located within the Commonwealth, the lien must be satisfied."
