Quote from @Theresa Harris: He should have a portable AC unit in his bedroom, but if they (the tenant) are causing damages/excessive wear and tear, do not renew their lease. 

I think my starting problem would be definitely having those excess funds.

The easiest give away is when they charge excessive points and don't have straight answers when you call them. 

(They must cover court costs in such cases.)Regarding potential excessive damage, I’d consider two points:By allowing them to stay despite ongoing lease violations like smoking, you're accepting guaranteed damage in an effort to avoid the possibility of retaliatory damage.

Try to get the quit claim, then try to get a tax lien sale, assuming the property owner gets the excess.

I expect return in excess of $1k/unit.  

Also sending multiple e-mail or text with no response is excessive.

Excess Liability Insurance: If you only have one type of liability coverage, such as premises liability for your rental properties, an excess liability policy might be a better fit.

In that case, I interview the tenant as to what appliances were in use and educate them on how to avoid excess amp draw. 

I’ve never used them but you can certainly try “the guarantors” who promise to pay unpaid rent and any damage in excess of damage deposit.
