50 unit apartment complex empty with no rent rolls nor expenses

[Brad Swearingen]

I have a lead on a 50 unit apartment complex that is empty, has no past expense sheets and no rent rolls.  How do I find out the expenses for this complex?  I use Rentometer to get some local rent prices so that shouldn't be an issue.  Also I want to look through every unit during my due diligence. If the electricity is turned off can I ask the electric company to turn it on for just one day?  Thanks!
