A short sale will at best, save you 60,000 today.
A short sale will create an uncertainty that in future, you may no longer be able to buy a similar house at 150,000 with 5.5% for 30 years.
You/your hu*****and are not the same kind of person mentioned in 1-2-3721. I am pretty sure the person is cheating on his/her spouse (or the two are cheating each other). You should feel luck your hu*****and cares about credit score, he is an honest man.
Your problem is a short-term cash inflow problem, try not to convert it into a long-term down-grading of your life.
You need to increase cash-inflow, in fact you only need 4000 (not sure if you have car-loan) or so per month to break even. With his employment insurance, you may only need to generate 2500 cash inflow extra in the next two years.
You could baby-sit for your neighbors, friends. You may even want to go to local elementary school to pick your friends' children. Create your own after-school program, teach them Chinese, let them work on math. Even cook them a dinner. You may charge 500-700 per month. If you have a van, eventually you can pick up to 5-6.
You may sell hot dogs (or fried rice, etc) in a nearby university during lunch time or brunch time. Your hu*****and may help you behind scene, while he is looking for a job.
By next May/June, if he could not land a job, well, it is time for him to set up an inhouse 'bu3 xi2 ban1' for Chinese kids. Focus on math, science, maybe bridge-poker, chess etc.You need your house, because it has more spaces (vs a 2-bedroom apartment) and it is in a decent neighborhood.
Think about it, there are many other opportunities in US.
