My question involves bankruptcy in the state of: Utah

Chapter 7 Discharged just over 12 months ago. Did not reaffirm the house, too far upside down and payment to large for the "New" me.

B of A is like talking to a shoe. Loan mods offered but not defined and without principal reduction it seems crazy to sign on any doc that puts me 75+K upside down again. So, got notice of deficiency. Worst case is I have another 60 days before I have to leave. Best case is much more.

Goal, Buy more time to save more money. I would stay here if we could come to terms that are palatable. There appears to be no mechanism for that discussion..

Question: What is best option for returning the house.
If a foreclosure will not show up on my credit I don't mind that route. House was discharged. But will it show up?
Short Sale,... Can I do that with out putting myself back on the hook for the property?
Deed in Liu ? what is the upside to that for me.

Sidebar question
In a short sale situation could my wife (who was never on the loan, and we were not married when I bought the house) Make an offer on the house and buy it? Wife's BKO was 24+ Month ago

Thanks for the input in advance
