Ideally I would want PM to find a new tenant for me but this has been really frustrating to the point that I am considering moving back so I don't lose too much money or get into any legal trouble in the process. 

Top residential brokers without teams on sales typically do about 300k to 500k ( New York and CA would be different as more money made but also lot more money spent on listings not sold so can lose your butt or do well).

You aren't losing anything by doing so and may very well find a qualified buyer that does not have access to wholesale or off market lists that is willing to purchase the property all cash

Let alone cover legal costs of a lawsuit.I am unclear how you can convince someone that bought a property on a wrap in good faith, that they must now sell, deed back or lose the property to a DOS call.The clear reading of a due on sale clause is:“the intent of which is the transfer of title by Borrower at a future date to purchaser.”Once a loan has had the Due on Sale called, it is tracked with special interest from then on.
