The physical amount of damage, and sheer cost to repair, caused from low volume, long term leaks is far too high to turn a blind eye to.

My plan would be to keep marketing your property on Facebook, Zillow, and Craigslist until you can get someone to physically look at your property with less concerning factors.  

In my experience, some investors tend to hunt down properties with obvious physical problem, i.e. tarps on roofs, overgrown lawns, broken windows etc. 

Additionally, the lender was a small lender who represented that this was a cut-and-dry foreclosure, and if my understanding is correct, the lender's attorney remembered physically seeing the client signing the loan documents.

Pilots are trained, tested, have to have a certain number of hours per type of plane to be certified, have their vision tested, have to have the tower's permision to take off or land, can lose their license if they fly drunk or don't pass a physical and so on.

Did you do a personal physical walk through of the property?

When at your home they approach you aggressively and make threatening comments; send harassing emails; don't allow peaceful enjoyment of your home; forced to move into a hotel due to their threats; spoke with officer XYZ on this date and he was concerned enough for my physical safety that he offered me a police escort just to enter my own home...You can also try to contact them and offer to break the lease with no penalty.

Many of our tenants couldn’t manage their lives; violence seemed to be a major occurrence with physical altercations, boyfriend beatings, armed robbery and family violence a continuing occurrence.4.

I purposely changed phone numbers and only have a cell number now that is not linked to a physical address. 

I started eviction paperwork for the original tenant even though he's physically gone.What are the next steps with the girlfriend since she's not on the lease?
