In addition, I would point out that the failure of this old PM to live up to their obligations caused you "damage" which they are responsible for.

And members crashed them occasionally a couple went into the ponds and some broken feet ( dragging their feet) but to me if you have guest and they let a teen on them with little to no experience if they hit something or someone they could really do some damage so based on my experince with them I would never do this personally.

Now if you have a general person who stops in to do other small tasks or do more property management style tasks (walking through the house to inspect for damages, drop anything off guests may need, change water/HVAC filters etc.)

And yes, I will pursue damages to the fullest extent of the law. 

The contractor estimate for the cost to repair the damage is approximately 93k.

You cannot garnish wages if you win a judgment for damages.

Perhaps my son being one of the tenants will help to mitigate the damage?

This can help mitigate potential damages down the road. 

I don't want to deal with property managers, let alone tenants who will get on my nerves by failing to pay rent or demanding a new stove, refrigerator, window, HVAC and etc., and breaking the drywall and kitchen cabinets with sledgehammer if I evict them for non-payment of the rent.

In addition, habitual late payments over the grace period can result in eviction which is very damaging and expensive.Bi-weekly rent is $225/biweekly period = $5859/year
