Hi Robcar If your comment about not being able to get an appointment with a bank is true, I think that is smameful-
In England and Sweden their would be no problem to see the bankmanager who would lot at your complete financial situation and try to come to a positive situation.
The Berean Iam not qualified to advise on the American system. Only to say consider the consequences of walking away carefully. Ie who benifits you or the bank if you walk away? I think the bank benifits. Secondly take the long term view how much do you think the home will be worth in 10 years.
All The Best
