It will depend on the the circumstances, the loan type, and the entity type.

There is no way sellers are selling at caps that high unless there is a special circumstance, so buyers just aren't buying. 

We can make exceptions with worse credit and slightly below perfect income but under no circumstances do we allow anybody rent one of our properties with a below 500 credit score, or 2x rent income or prior evictions. 

More than likely, you’re going to encounter some kind of problem or unexpected circumstance at some point.

California law requires abandoned tenant property under certain circumstances to be sold at public auction.

I do not do business in CA under any circumstances.

There is no penalty for the tenant to end the lease at any time with a 30 day notice"...And the reason I did this is because it is very important to me, with small town circumstances and dynamics for my family in the town the rental is located in, that the tenant not be disrespectful or unfair in any way. 

IMO, it all depends on your circumstances.

And in these circumstances the chance of the buyer being sued for a default is rather high.  

There are outlier circumstances and big-picture strategies that could potentially apply; but that's why they need to talk to someone about their specific situation.
