This is something I've been wondering too. My situation was a little different though, in that I was financing, got laid off in 2015, and then Disney offered to have me.just sign the contract back to them with no more owed, instead of going through a foreclosure. It probably made a difference that the contract was worth about the same as what I owed, so I wasn't underwater or really had any equity either. I do wonder if I could ever buy again though. I'm guessing maybe, because it was a friendly transaction, and they didn't have to drag me to court or come after me for collections or anything.
Given what's happened since then with both the theme parks and DVC, I don't know if I want to buy back in though.
