Do you have the power on when you wholesale the property?

[Bienes Raices]

I'm not a wholesaler, I'm a potential buyer. I called the utility co. and the property I'm going to see has the power turned off right now. Is this the norm when buying from a wholesaler, and should I go ahead and put down my deposit (if I like the place) without having the power on to test it? What is the best way to handle this? Thanks.
