Getting the lowest balance out of the way is usually the quickest way to start snowballing extra payments into other debts you want to clean up. 

Instagram is such a powerful tool for real estate professionals.

Lol only kidding, but seriously you can offer cash for keys but stipulate they leave the home clean, it will save you a lot of money just in labor cleaning up the place when they leave and if they leave it dirty remind them that was the stipulation.

NOTE: We have a specific POA - power of attorney given to us to act on behalf of the loan borrowers with regard to THIS property and their loan.

I would start with a written violation and demand they clean up their act or move out.
