He was very abusive and she would often have to call the police on him and he'd be sent to jail.

Countersue for abuse of process.

Your job is to keep the tenant happy, not piss them off.Notwithstanding intentional abuse, I consider plumbing, electrical, HVAC, etc. as normal wear and tear and I have repaired and move on.Next time a situation like this arises, I suggest you (or your management company) respond immediately and have it repaired and NOT stick the "repair policy" in their face because, as previously pointed out, that policy is incorrect.

I've never heard of them actually doing that in our market, but it seems like it could be plausible if there were enough guests to abuse the network.I don't think there is an absolute perfect ironclad solution.

Maybe they will be 100% higher and you will want to choke yourself for purchasing only one property when you had what it took, at the time, to purchase 5 properties where you would be living on Easy Street, today.I have to tell you the same story I write almost every day about the 20-year old Japanese girl who ran away from Japan because her parents physically abused her.

There is a friendly report abuse email on ICANN...we'll see if anything comes of it.

Then the deluge began from the ex-GF with all manner of accusations: abuse, drugs etc etc.

A: I don't have any control over the trust and for political reasons I'll just say it is being poorly run/abused by another family member.
