Ripped Electrical repair work cost

[Jenna Walker]

Hi Everyone! 
I recently bought a house sight unseen.  House is decent shape but anything that could be worth is taken out of the home. 

I have noticed that they cut all the wire/ piping.  Pulled electrical cords from each light sockets.  

I am trying to whole sale this property and would like to know how much I need to discount on my end if I count electrical repair work.  Any advice would be highly appreciated! Thanks guys!
