Our plan is to send out 200-500 letters by the end of the week targeting these three groups in our 1-zip code farm.  

To take it a step further you can research zip code demographics, local crime data, schools and education, and job growth.

I would then find my own tenants and collect first, last, deposit whatever the state code allows.

By mid November we received a letter from landlord tenant court notifying us that the property management is taking us to court for non payment of oct rent, now mind you in pa if license and inspections deemed a property not up to code the rent cannot be collected while in violation of said codes, they were not up to code by November either, so any who we went to court showed them our evidence and explained why we were not continuing on to live there, the ruling was withdrawn without prejudice?

Code Civil Article 1861 "Le locataire est tenu de réparer le préjudice subi par le locateur en raison des pertes survenues au bien loué, à moins qu'il ne prouve que ces pertes ne sont pas dues à sa faute ou à celle des personnes à qui il permet l'usage du bien ou l'accès à celui-ci."   

Although your property and that community share the same zip code, your values are not going to measure up. 

But since you're an agent you have the ability mine data of zip code or neighborhood to see number of sold properties and for how much they sold for.

A tenant has the legal right to refuse to sign a new lease, while a existing lease is in place, even if it is exactly the same as their present lease (unless state codes specify otherwise).

Calling 3 times a day, videotaping tenant, calling code enforcement and now the health department.

If any of these did exist and the community were to hold the owner (biz mgr) accountable, there could likely be many code violations issued by the local township --  Then maybe there would be some motivation on the owners part to sell the property.It is a shame when financially capable owners allow a property to exist in shambles.
