If I was in your shoes I would definitely talk to counsel. 

The cities you listed are outliers -they are the most expensive places to rent because people will live in anything there, even $3,000 / month shoe boxes.

Then, I did more research and the family was worried about the tax consequences of doing all straight sales and changed our plan to trading these wildly appreciating condos for true Multifamily and more cash flow to help us to be financially free.More education by reading, attending an excellent 2 day workshop, and talking to many people that had been in my shoes at one time, we chose this current route.  

The $5K for suffering was due to the wife having to change shoes from heels to flats to climb the steps out of the parking garage.  

Treat people like you'd want to be treated if you were in their shoes. 

I can't provide any advice as I have never been in your shoes, but it sounds like you and your brother should be able to evict her with enough proof of what is happening.

If I were in your shoes, I would at the very least advise the tenant (via phone or letter) to reach out to his/her social worker ASAP for help on finding new housing.

I'm in your same shoes where I have a multifamily and  I see the tenants doing so many wrong things that I clean up because it is little.

Were I in your shoes, I would order a certified home inspection to ensure you know all the items that will end up costing you money.

It means the tenant has the right to not have the landlord interfere unreasonably in their possession of the home while they are renting it, their right to quietly enjoy the property without the landlord's interference.I think landlords forget to put themselves into the shoes of a renter.
