The only exception I can see is if the tenant leaves on their own volition, or if we give them a for-cause.

I make repairs as soon as reasonably possible, I make improvements on my own schedule and by my own volition.

Depending on your state, you may still, as the owner, be required to notify them that their contract is expiring and you do not intend to renew.Here is how I would see it play out in court: you sue both for eviction and non payment, and the husband either proves that they are separated and that wife stayed of her own volition, or that they are both liable for either holdover rent or are squatters.

Id party like its 1999 if a tenant like that left on her own volition or valition. 

The agent has access to every home listed on the MLS unless there are specific realtor notes barring entry until a contract is accepted.You haven't mentioned what you have set as criteria so I cannot assume the agent is doing this on his/her own volition.

I agree with this move, as someone who manages STR as well as traditional rentals, we see owners with dollar signs in their eyes and not ready for the volitivity of STR's. 

but you would know better than me since you already own rentals there. but if they move on their own volition.. then I am thinking you upgrade at that point.. 

To wit some builders are mandated a KW max per square foot & left to their own volition.

Look into R&R Real Estate (Karadza brothers), Volition properties and the like.
