Instead of going into a short sale or a foreclosure - rent the house out. Don't just walk away from the property....it affects more than just you. I don't know nor do I understand the sheer ignorance of people who do this...sorry - not trying to be mean here but really?! This is a debt that will follow you...you are legally responsible for it...doesn't matter if you live in Timbuktu - it is YOUR DEBT.
I don't know the laws in Michigan - but I can tell you that it would NOT be wise of you to foreclose on the property ESPECIALLY if you have been making payments. If you have not been making payments - then find out what you can do or if there is a program available to you to help you out so you can avoid foreclosure.
If you walk away and foreclose - your credit will be tarnished for AT LEAST 7 years...YES they can garnish wages and tax returns. YOU WILL STILL BE HELD RESPONSIBLE FOR THE DEBT!!! So instead of messing up - lease or rent it out.
As it stands, you state you plan on moving to Texas in the next year. Fine. Put it on the market NOW and start trying to sell it. If you cannot sell it - rent it out. The ramifications for foreclosure are not just about YOU - the affect everyone around you - your neighborhood, your community and everyone else that owns a home. if you can avoid it - do.
I know stuff happens. Job loss, etc. okay - got that - but really - if you are making your payments, there are programs out there to help you....don't just walk away from it. It WILL follow you. it IS your debt.
