There is a little known loophole in US law going back to the Great Depression era which allows homeowners with outstanding mortgage debt to put the keys in the mailbox and simply walk away from the outstanding mortgage debt.
Under this law, banks do not have the legal power to recover the outstanding balance, and it is fairly easy to even rebuild your credit again in a few years.
So, you've walked away from mortgage foreclosure debt which was unresolvable and want to start again - now what?
One of the easiest ways is to start your new life in another country. One of the easiest ways of doing this would be to get a TEFL (teach English as a foreign language) job overseas.
Many of these employers will even pay your airfare there and back, plus lodging, food and paid vacations.
But the options to escape your situation are in no way limited to that; there are many authoritative sources online on topics such as overseas properties, expatriate resources, international employment & offshore financial services.
