Apparently she has a lawer already and is threatening to sue. 

@Russell Brazil1 tenant was furloughed but still insisted on paying. 1 tenant threatened to not pay not because she didn’t have the money or was unemployed but because she was “scared”.

If someone is causing damage to your property or creating a nuisance that threatens the neighbors, you have to step up and deal with it.

If she asks for an outside hose bib, do NOT do so, unless it's in the lease that you will provide this.If she threatens to withhold rent because you haven't done what she is demanding, don't respond. 

She threatened to sue for all of the costs they'd charged her that were completely unreasonable maintenance costs and lo and behold, they decided to waive the termination fee.But, people should know that most PM contracts will charge them to find bad tenants, deal with bad tenants on a regular basis, deal with maintenance issues that are hugely overblown, then deal with terminating bad tenants, and then to find another bad tenant, and even to fire them.  

His agency threatened to terminate him if he violated a government employee movement restriction by leaving the local area (50 mile radius) of his primary residence on record which had left as his parent's house which is 90 miles away.

I didn't accuse anyone with abuse or user damages.I have tried to be transparent about the issue, explaining I have been threaten with fines for doing work, service call fees are double/triple the costs, and it just comes down to, its cheaper to buy a new dryer ($475)To add to the issue, I have a 3rd year law student and the other unit is some 24 year old that works at a Big 4 Firm who think/view this is an unimaginable inconvenience, and the law student is citing all sorts of legal codes on why blah blah blah is a certain way, but obvious has never been to small claims courts where paperwork and circumstances matter greatly, or the costs of having to deal with the this stuff is problematic.

I've seen tenants blackmail their landlords and threaten to turn them in to the City's Code Enforcement when they don't get their way.

Tenant now is threatening to "talk to his lawyer" for the pain he / his family (wife + baby) have been through, and that he is "collecting the evidence". 

Yes you can try and force them to pay based on the lease, and even threaten them, probably won't do any good though and only cost you time and money.
