First, you need to decide do you want to keep the house. If you do, then the HOPE approach is a good way to go. You can also go to NeighborWorks which is a non profit with offices aorund the country, including sacramento. Their website is www.nwsac.org. THey are great at helping people stay in their homes. Totally free service.
On the other hand, since there is no equity to split, it might just be easier to short-sell the property. This is usually better than a "strategic default" where you walk away form the house and let it foreclose.
So, the decision is to keep it or not. Either way, there are simple outcomes. Your divorce lawyer can advise you as to which path makes the already terribly difficult process that much easier.
