sub2 in foreclosure

A couple of questions for the experienced sub2 deal makers,

Has anyone had an experience that a bank invoked the dosc on a sub2 foreclosure because they just wanted to get cashed out?

2nd question: In the past if the lender did invoke dosc, one could refi to get the payoff money. Now, with lending standards so tight, can a no-seasoning, no-doc refi loan still be done? If not, what is the exit strategy? Flip to another investor who can payoff the loan?
