., AC units stolen, pipes and wiring ripped out, window broken, door kicked in), significantly more challenging tenants, and neighbors whose actions reduce your property value (e.g., building code violations, drug activity, squatters, loud music, loitering, littering).

The best action would be get fully approved with condition on tbd property.

Not exactly stock market fluctuations, but even commercial properties are sensitive to market forces when translating how much that NOI is worth on the open market

What is the reasonable course of action to maximize potential here?

That way you can keep your personal things out of reach by any legal action.  

However my experience is that many people claim they knew nothing about a court action and yet the plaintiff has proof of service. 

That one mistake that costed me was also a very valuable learning lesson and has saved me since because I took action what I once lost, and it has since been something that I am glad that happened to me because I really understood what I learned from that. 

Let me preface that I have bought a home from hoarder before and we are very sensitive to their difficulty. 

@Shyla HydeAs long as the property has not been lost by legal action to the tax sale purchaser you can still move forward with the purchase.

They may own (free and clear) a nice car, some jewelry or other items of adequate value (or preferably great value) to act as compensation for the lost rent.I'm not suggesting that you open a pawn shop service for wayward tenants, but in this one case, since you're seem to be having difficulty taking direct action against the children's welfare, you might want to barter for the missing cash component of the next three month's rent.Like others above, I however still confused about why you as the listing agent are burdened with this decision.
