The lawsuit will come way before the Due on Sale Clause execution...Keep the property performing well, pay your note...raise your liability limits...

I a now having to regroup to redefine my role and build a high performance team to d the things I am not so good at doing.Step 5.  

Having worked so long in massive organizations where career progression has more to do with superiority than it has to do with job performance, I've noticed my own work ethic slowly slipping away.
