PR does not want to keep the house but at the same time hinted at getting retail.

There are very few protected classes and they don't include "people who smell like smoke," "people who don't completely fill out the application, even after I tell them it's required," "people with pit bulls for emotional support animals" (hint - emotional support animals require you to approve a "reasonable" accommodation - which means asking you to break a rule of yours - but it has to be reasonable.Knowing the rights of landlords as well as tenants. 

Just a hint. 

They have hinted to some that they would sue if the machines are removed.

Find the intersection of Cleveland Ave and Weber road, and look for the giant hidden dick in the map (hint: just northwest of Cleveland and Weber)...

I painted my place with Behr papaya sorbet and it's got just a hint of gold so it gives an otherwise beige just a hint of sunshine about it. 

If they start complaining and pointing out a lot of issues and have any hint of drama, I will either make it a condition of the sale that the owner have them vacate prior to closing, or I give them a 20 day notice as soon as I can (if they are month to month).In your case, I'd probably call the tenants (make sure you get their info from the owner) and let them know that you are the new owner and that you'll be mailing out a notice to them for where to send rent payments.

I hope folks aren't reading what you're saying and assuming there is even a hint of factual accuracy to any of it.

Hopefully, someone will chime in who knows what my old brain is hinting at. 

@Kurtis Delahooke Thanks Kurtis, a few comments above have hinted at the rather high HOA.
