If you are really only 8K short, you should be able to find a solution that works. I would recommend meeting with a good realtor in your area and also get an attorney on board that does a lot of work for the lender your loan is with. If you get the right players involved you should be able to come up with a solution. best
I agree with David, hang onto it if you can. That $8k short you mention, does that include all your selling and closing costs? If you use a broker they'll need to get paid, then you have tax stamps for MA. So if you were going to try to cover the deficiency with a personal loan you'll need to cover these as well.
The market is improving. If you can hang on, do....
If you don't have the $8000 you may want to look at drawing a personal line of credit or some other loan to help get you the money to dump the house, then you can pay back that loan in the upcoming months or years.
Otherwise, you can try to talk to your bank, but I doubt they will approve releasing the lien without going the full short sale route.
