As an aside, I have a separate cleaning crew I use for my buildings as I find most contractors are NOT good at cleaning. 

Obviously, the companies will try to boost up the rental to entice you to choose them as they indicate they can get this rent; however, I've had analysis done with separate companies both came back with similar figures ~$2100/month rental (they have not performed an in-depth analysis just based on location etc). 

Can I separately measure use and bill them for it?

I have a seller who is renting each room to 4 separate tenants.

This is because building a house and investing in housing are two separate and very complicated disciplines on their own, by themselves, independently.

I literally spent 4 hours on two separate occasions talking with the IRS as to how they would suggest setting up the fund. 

Since then its been rented for the last 5 years , It is completely paid off and cashflow is now approx.. 700/month I found a single listing property just outside of city limits which has 4 separate a frame homes on same location.

With detailed accounting I believe you can get the material costs separated out.But, back to your question.

You can run this property through a separate bank account without using an LLC.

And as it turned out, that junction location in the bathroom was a separation point, where I could at least separate the circuit almost in half, with a new wire run that is (second floor unit with a tenant below).
