But I will be covering utilities since I'll put them in my name and will keep account of future CapEx, vacancy, etc.

I am already having them put vinyl planking in all the floors including the bedroom and both houses have separate utilities.

I don't pay for any utilities.

Others have been split into separate units with their own kitchens and utility meters.

Or is there a way to utilize my existing LLC, but to have a specific carve-out unique to this (and future) partnered-properties?

Rent for all three renters would include utilities.  

I have access to quite a few off market deals and plan to start utilizing my marketing for my own investment properties to help get others into properties as well.

The package provided by the owner only listed monthly expenses of $415 (not including taxes, insurance or utilities).

and need the utilities on.  

@Bob Okenwa Thanks for the response Bob, I have heard of many other investors utilize 0% credit cards effectively for rehabs, and I do like that idea, I just have to make sure I have a solid plan to pay them off, like you said.
