Figuring Bills and Rehab Cost

[Johnnie Bembry]

I’m a newbie and I’m looking into an 8 unit property. I have most of the numbers I need but I still need utilities costs (owner paid). How would I figure out how much the gas, electric, water, trash, and sewer cost per month? Is it as simple as just calling the respective companies?  

Lastly, to determine how much rehab is needed for each unit do I schedule a walk through with a contractor or is there someone else that’s better for determining those costs? 

Thanks in advance!
