I think landlords often misunderstand cooperation for enjoyment of their company.  

She also mentioned on one of our conversations early on, that if she would of known that she was gonna be given the notice to vacate that she wouldnt of been so cooperative when showing the property.  

@Joseph Lewis, Although there are some landlords that do quarterly inspections, every six months is doable for most tenants, and, yes, you will definitely want to include wording about doing inspections (necessity and cooperation of the tenant) in your lease agreement.

Our response is that we support that but we still cannot let them move out in the winter...during other months would would let them break their lease without charge so long as they are cooperative in assisting us in re-leasing the space (60 notice given, apartment is in showable condition, and they are flexible in when we can show it).  

And that while they are on a website that encourages co-operation and information sharing that benefits all of us!  

If they cooperative and let you know they want to leave and you agree,  you can't evict.

No help from Sec 8 with any costs including repairs. ...We're you enrolled in the PGW Landlord Cooperation Program (LCP)?  

If the tenant does not feel threatened, they will be more likely to cooperate.

Sometimes you have to try knocking on the former landlord's door with the tenant applicant's authorization to release info so the landlord realizes that cooperating might not be so terrible after all.

I'm fine with that, if they cooperate with showings, keep the place in good condition, and I can rent it without vacancy time.
