Are you asking how do you know when to use meters in each plumbing configuration or just use a RUBS system?

There's ZERO downside in asking; there's likely to be some deal configuration that would make both parties happy!

Those are mainly what I’m seeing in that price range, bed/bath configuration, and square footage in the Fayetteville area.

Broadly speaking, I'm looking for guidance for hardware and configurations?

give me the configuration, and address.

., are you keeping the plumbing configuration the same and replacing with new fixtures or will the plumbing need to be moved around? 

Giving you the stability of a long term rental with the higher, but sometimes seasonal, returns of shorter term rentals.Making sure they do not configure the house in a way that would limit them from renting it out to only one type of strategy is also a consideration.

That is especially true if it is configured in a way to add a pullout to sleep another 1-2 people.

They configured the back of the house to be a 2/1 attached ADU of about 750 sqft.

Because of that feature limitation, I ended up swapping them out for dumb irrigation controllers.As an experiment, one time I tried leaving a pre-configured wireless access point with a tenant specifically for smart smoke detectors and irrigation controller, but the tenant objected because it meant I could potentially access their network whenever I wanted, which was theoretically true (not that I would do it).
