We're pissed beyond belief and just want her out now so we can stop dealing with her lies and delay tactics.  

Idle scare tactic threats..... they are full of BS 99.9% of the time.

With all due respect,  I think raising the rent to something unappealing to her is absolutely the wrong tactic.  

Oh, and agreed that seeing if he wishes to buy it at a "favored" price--perhaps just a part of the commission--is good tactics and in some states the law that you have to make the offer. 

It ends like this:1> Airlines, bars, restaurants, Casinos, Cruises, the entertainment industry , malls, and misc companies will get bailed out using taxpayer money. 2>These bailed out companies will take the money and pay compensation to their top-level executives, continue to do stock buybacks3> The stock market will rally.4>The average joe taxpayer will get NOTHING and will be our of the job and screwed- AGAIN.5>After many are dead and there is full-fledged fright leading to a mandatory lockdown, the cases might drop6>Persident/GOP will say he is solely responsible for fixing this and will take full credit and will take no blame for this.7>DEMS will resort to the usual tactics with their tails between their legs.8> CNN/MSNBC/FOX will continue to do their crap reporting while profiting from the stock market rally and bailouts9>Toilet paper/Hand sanitizer hoarders will try to return their excess toilet paper to Walmart10> Going forward BP members will ask every 5 days the following question in the forum - Is there a recession coming?

Not that I agree with your tenant's tactics, but I understand their perspective.  

Have 5 marketing tactics to find deals.

That tactic works very effectively and the word gets out quick.  

And ask them why they are delaying someone actually trying to help the city's housing crisis during the pandemic.These kinds of tactics have served me well when nobody is listening to reason. 

I'm pretty sure other tactics like saying "I only accept 11 month leases" because section 8 requires 12, are also asking for a discrimination lawsuit.My understanding on this (from lots of reading but no direct experience)  is that you can apply the same rental qualification criteria to a section 8 applicant as any other - credit score, prior landlord reference, criminal background check (except in seattle) and so on,  however when it comes to income you are only allowed to verify the tenants portion of the rent responsibility.
