The LLC needs to be separate.

We purchased the kit from Jet Utilities and had to hire a separate plumbing service to come out and install the components.

@Manas M.Instead of registering your LLC in two states where you will have to put your name on public records in the second state, it is often recommended to open a separate new single member, member managed in the second state, where the member is the holding anonymous LLC.

basically in most jurisdictions you must be in the city limits to access city water city sewer city storm drain.power tele and internet and gas many times is separate and called franchise utilities and can be available to those out of the city limits. 

Do you have a separate advertising website (just like a one-pager) or anything else apart from being directly on the AirBnB/VRBO app?

It would cost more to hire someone separately.

It's better for me when my contractor buys the material, but I always want to see a breakdown, separating labor costs and material costs.

I just close on 2 separate duplexes in your price range using fha with 3.5% down payment. 

@Will Fraser would it benefit me tax wise to separate the companies? 

It creates separation from you and the assets, so that a lawsuit to one doesn't affect the other.
