@Dave RavThe security for a note than includes real property is the real property itself, the lien is perfected by a mortgage or deed of trust that’s filed with the county in which the property is located.

Another risk especially given as you say this home is in need of major work - the tenant could start filing complaints against the home's conditions as soon as it is sold -  which would put the brakes on any removal process AND force you to make updates to the home for their benefit, or force you to pay fines and pay their moving costs.   

I do NOT want to file for non payment although I feel like a "7 day pay or quit" notice would get the ball rolling and would cost nothing for me to place on the door and would certainly motivate her to move more quickly.

BP has their lease files - have you checked that out?

Anyone have a decent service or lawyer that can file for tax appeals?

@David McHenry Jr. yes, you apply for a TPT from AZDOR and then file your return and pay taxes through their site.

That causes me to be concerned about the type of insurance you have on the property if you ever have occasion to file a claim.

Could get really creative and have a private lender file note and mortgage and then do a rate and term refi. 

Hi,I am considering to buy one or more investment properties via a cash-out-refinance against another investment property which we already own in our own name.For which property can/do I deduct the paid interest once I file my taxes?

Tax time, export out of the accounting software, import to tax software, and then taxes become as easy as filing a personal return.
