Do I have to have my EIN before turning power on, water, etc?

[Daylyn Massey]

Newbie here! We are closing on our first property tomorrow afternoon. We filed for our LLC and we have that established so when we sign the closing papers the house will be in the LLC. We are being held up with our EIN for the LLC because we had to do it by fax instead of online. After speaking with the electric and gas company we were told that to establish an account for the rental house we would need the EIN. Is it okay to just get everything in our name so that we can begin work on the house and then switch it over once we get the EIN? or do we wait the extra week or so and just be patient for our EIN and get everything established once we have that? I don't want to waste time and sit but at the same time I do not want to rush the process and end up screwing us in the long run.

There was also the question of mixing funds but it sounds like since we are not making any cash flow that most expenses will fall on us instead of the LLC. Feel free to correct me if I am wrong! I appreciate any help!
