But, whatever he sprayed must completely knock out any scent they leave for other wasps to find, because they completely disappeared and they were a constant problem before - no matter how many I killed, more kept coming, until the magic, toxic stuff got sprayed on their spots.I'm afraid to learn what that stuff is, lol, but I'm really glad they're gone.  

The threats to my life.

My success on the $15k owed to me in damages and missed months was an email the length of a dissertation with a list of excuses including mold (nope, $800 of testing confirmed, they had a pet peeing on the carpet creating a bad smell) , _______'s cancer which came and went quickly, "having kids is hard", 1 of them starting college, and then an expected disappearance.

I had zillow want 9.99 a month ago, but then the request for payment disappeared.  

Do not call the police just to get him out, only call if you fell he is a threat to himself or others.

I had to explain that while they were noisy and ugly as sin, they posed no threat to humans.

Financially speaking the threat is that capex will start to exceed cash flow a few years into the investment - aka money pit.

let them direct their threats to the lawyer he'll tell you the ones to worry about. 

Savvy tenants aren't going to just believe you when you say it will be cleaned and painted and in pristine condition and available on the day it's supposed to be - when they are stepping over someone dirty laundry.And, they won't feel comfortable looking inside closets or the garage, etc.And, there's the potential liability of your current tenant claiming some expensive jewelry disappeared during your walk-throughs.I know the idea of having to eat a month's rent in-between tenants hurts, but I truly believe you get better tenants, who will not be as likely to cost you in problems, if you clear out the last one, get the unit in beautiful show condition, then start showing it.  

Would it be possible for him to say you made money disappear that he actually spent, etc.?
