If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

Quote from @Quinn Olivarez: If I were the original seller, I would tell the bank I sold the house so that I could get the ball rolling on getting it out of this sub to agreement that is probably not enforceable in most jurisdictions.

The sooner you regain control, prove that you fully intend to enforce the terms of your lease, and that you will not be 'played' by their recall of events or documents, the more effective this action will be.  

Henry,Good to know the technology and law-enforcement is working for you while you’re you’re out of the country.

Not sure why any renter would abide by a lease if they are not enforceable.   

@Placeholder PlaceholderOne word of caution I would advise: If a community or local government is enacting restrictions and also regularly enforcing them, then its often a reflection of the local community sentiment which increases the chance of a neighborhood or nearby resident calling you in if they think you may be running an STR.

If I am wrong, then please clarify what is and what is not allowed in response to someone stating that they need a CPA.If I am correct, then let me tell you that these rules are enforced very inconsistently, and there're a few people who have been committing these violations repeatedly for months, seemingly without any repercussions for this behavior.

They may take an interest.Some of those people might actually be more aggressive about enforcing existing laws.

Sellers sign a settlement disclosure regarding rent and escrows that is enforceable.  

Learn to set boundaries and enforce them.
