@Kris OsbornI had managed a 6 unit with a sewage ejection pump!

If all else fails start an eviction or ejection.

The property appears to be vacant and abandoned and this has been this way I assumed for several years and most definitely the last 6 months.My question is should I try and get in touch with the owner once I receive the deed and try to do a QC, Ejectment or should I let a sleeping dog lie.

Normally, I would just issue a pay or quit notice and then move for summary ejectment when the 7 days was up.

Not sure yet.Anyway, it appears that if tenants are unlawfully occupying property, you can file an ejectment action.

So if I buy the tax deed, the only way to obtain legal rights to the lease and revenue of the billboard is to  go through the full ejectment and quiet title process?

In our case, we made the effort because a) we're on our 7th property, b) we have sufficient reserves to weather ups and downs with the property c) we have an attorney we've previously worked with and trust to help us with the resident ejectment, d) the purchase price was low enough to give us sufficient room for error, e) we have contractors with whom we've worked who we believe can timely renovate the property and f) we were prepared to get it wrong and either lose money on this or sell the property at break-even, a small profit or a small loss. 

Can anybody recommend an experienced attorney to handle the ejectment?

Had a lawyer friend tell me I had to file for an ejection in circuit court and not eviction. 

Philly is a tenant friendly city so buckle up because ejecting squatters can be long and costly.
