Can you cherry pick default notes?

[Sam M.]

Ok, I have done some research and it seems as though one might be able to cherry pick default notes from a list. I have heard of people doing this instead of attempting a short sale.

How is this done?

How hard is it to get notes on a specific property where you already know the note is in default? (Liz pendens filed)

At what point in the default process is it the best to go after these notes for the acquisition of the property?
Thanks,
Sam
