If not it likely can be overturned for lack of consideration.Did the attorney representing the LLC inform you that they only represented the LLC? 

Almost every PA court case overturning a tax sale is overturned on bad notice.In one case I researched, the judge overturned the case, because notice was sent to "Smith Debbie", and it should have been either "Debbie Smith" or "Smith, Debbie".Effectively there is not time limit on an appeal, only a time limit on the appeal AFTER the former owner finds out about the sale. 

That is exactly why courts will eventually overturn these laws, but much damage will be done in the meantime. 

Is there a redemption periodWhat are your rights during the redemption period.Generally anyone in the chain of title can challenge a tax sale. if it is overturned then you should get your investment back.

"blanket discrimination against felons"I think these ordinances will be deemed unlawful or overturned or changed and watered down to a point that they don't have any real teeth to the ordinance.A felon is not a federally protected class.Blanket is the key word you used which would imply SWEEPING discrimination which would be almost impossible to prove.A landlord would simply find another reason not to rent to them.Just like a contract there are always more loopholes to use if you don't want to do something.

The courts here end up overturning these sales on a regular basis, with a simple hearing.

Our clients do it both ways however, I would have your attorney work with your provider so you have a plan if Swanson gets overturned.

By the way , Thanks for the input guys, every since 2011 when the judge over turned that ruling, the ambulance chaser have been coming out of the wood works and i get mailings to my house from lawyers doing mass mailings asking me if i have resided in a residence where lead my have been present.My father , whenever he buys a property, he guts it completely and has the xrays done so he doesn't have to deal with it .

Still in place or overturned? 

My question is, "For those who would overturn Roe v Wade, should children born to mothers who can't afford to provide healthcare, food, clothes, shelter, etc receive government aid?"
