Closing this Friday!! Need some guidance

[Sabi Const]

Closing is scheduled for this Friday and I have some questions.

This is meant to be a flip and I am not sure what are the first steps... I am buying it in my LLC and am curious if I should apply for a commercial credit card at the Home Depot or should I use my personal?

Also, what should I use to track expenses? Does an excel spreadsheet work ok or what program works best?

What about utilities? When do they get put under my S corp? How about taxes being paid while owning the property?

These are some of the questions that I am thinking. If there is anything else, please feel free to post.

Thank you!
