You've probably heard of big Landlords losing property, but only because they were flagrantly violating Fair Housing, running a slum, or otherwise violating the law in an egregious manner.

HOA violations or fees racked up by tenantsF.

I said I would 'consider' it if we are able to address the existing lease violations. 

It violated HOA rules for you to rent to a sex offender so the lease should not have been entered into in the first place.  

@James McGovern, while I don't necessarily agree with your language, I certainly understand where you are coming from.If you truly want to exploit them, then continually report code violations: long grass, broken windows, broken down cars parked on property, anything that will keep racking up the nuisance issues of the property that the landlord not only has to handle with effort but also with money...But, assuming you don't want to go to that level, find the owner and reach out.  

Make sure it explicitly explains the process for termination if you are unhappy with their services, especially if they violate the terms of your agreement.3.

A STR is a commercial entity and you would be in violation of those covenants.

Our experience with rental licenses in various municipalities throughout Kansas City is that they really don't look for any permit violations at all.

Further, a broker that “pocketed” a listing instead of advising the seller to place it on MLS and seek a bidding war would be committing a violation of fiduciary responsibility to their client.  

Wouldn't get involved in tenant personal matters unless they are violating something in the lease or endangering others or themselves.
