Best way to get out of my Mortgages, moving out of state for job?

Anything that has you not paying your bills will hurt your credit and increase costs for credit later on. This includes not getting finance or paying a higher interest rate later on. I knew one person who declared bankruptcy and he could only get a 4 year old car with 18% interest rate. Regular rates were around 4-5%. If you do walk away make sure you do not want to own a house for many years, because it will be very hard to afford one later.
