I can't imagine how much it is going to cost to rewire a place like this. I've done wiring before, and one drop can be difficult on an existing unit, let alone rewiring an entire home!
I attended a Closing on a deal in Indiana this week and the broker told me people in that area are breaking into buildings right and left stealing all the wiring. First things to do - Buy INSURANCE to activate day of closing and Install deadbolts/security systems the day of, although neither will guarantee anything. These are difficult times and life is not fair.
You also want to be aware of the condensing units placed outside your apartments in your communities, as there was a property in the Atlanta area which had I believe 8 units stolen. Copper is very expensive and Felicia is right on the money, because a lot of addicts find this easy pickings in some communities. Even some residents have been known to work with these criminals as well.
