Stop.

The tenant suddenly stopped paying rent, claimed 'banking glitch' and squatted for 6 months while we worked through the evictions process.

@Jay Hinrichs how about one stop shopping at Costco.My other thought is that RE brokers should not cooperate with other brokers but sell their own listings for 3% and handle the financing.

At this point, they'd only sent me 3 properties and I realized it might not work so I requested we stop and honestly thought it would be a really reasonable request to return the 20k deposit/finders fee. 

Even if you're caught, you cough up like $5K and then find another tenant, or just stop renting it out and you're back to where you were.

Stop hanging out with your deadbeat buddies who spend all day drinking, talking sports, and otherwise wasting away.

None of these strategies will stop the claim from being filed.The second part is what happens when the plaintiff or plaintiff's counsel knows you are a member or the sole member of the  entity that owns the property? 

Having an expert landlord attorney involved will help you a lot.As for the actual question, it is very difficult if not impossible to "stop" a tenant from damaging your property, because you are not inside the property to know what they are doing.

Yeah we stopped buying in Berkeley due to the city.
