Although you live in one of the units, you are treating the other like a business presumably and will be reporting income and expenses for tax purposes so you really should have a separate bank account.

I know some states frown upon aspects of that practice but I presume that Arizona is not as regulated.

This was the strategy I used when I successfully sued the my state government on behalf of my disabled son.Your ex-tenant needs to prove that she was injured, and that your actions were a "proximate cause" of her injuries, and that the amount she is suing for is reasonable in light of her presumed injuries. 

The 2 bedroom is an 'easy' fix as there is presumably a window with egress, so adding a closest is simple. 

@Matthew Mclean Generally yes presuming your goal is to get a better rate. 

So, I would presume that if a tenant sent a partial electronic payment I could simply refund it even at the court hearing claiming that I am not accepting the payment.

You'd be dealing with 5 different sellers, each presumably with their own challenges.

Then presumably you will only get a piece of the action, since you require the person who is owed the overage to agree to let you collect.Ultimately, it's a lot of work for probably not that much money.

Logically, the counterclaim being a compulsory counterclaim, and the one shot at fixing mistakes or surprises (because you didn't know about the tax sale, presumably) having passed, it is all over for the taxpayer.

Here's what I'm thinking:Find a duplex right around the $1M price tag, where one unit rents for around $3,500, and the other unit could presumably rent for something similar, or slightly less.
