its is too bad it has only been 7 years or else adverse possession would apply (15 years). 

If the property has been abandoned then you should be able to schedule with a locksmith and a sheriffs deputy to take possession of the home.

I would have the one moving out sign a RELEASE OF RIGHTS TO POSSESSION form so that you don't have any problems in the future with him. 

My property has mold, termite damage, water damage, a drawing of a possessed clown on the basement wall...Another reason I was bidding against cash offers.

You can not take possession of property for 20 days after auction date.Property owner gets 180 day redemption period unless it's a homestead exemption /ag exemption property then it's 2 years.If property is redeemed they have to pay you auction price plus 25%.

They should possess all of the tools of their trade not depend on  a client to provide them the money to run down to Home Depo and buy saws for his crew. 

In PA, the broker/PM holds the deposit in escrow at a named financial institution and has under PA L/T laws 30 days after move out/possession to send detailed report of damages and balance of deposit check (or notice of amount due) to the tenant.Second:  whether or not the PM notified the tenant(s) is open to debate, "he said-she said". 

(In reality it was a 260/month increase and I spent 35.5k on repairs and improvements before he took possession.

We can offer him $160,000 cash but we will need possession to he house right away.

A quiet title order will require 3 years of possession, and about $1,500 to $5,000 in legal fees and court costs.
