Nobody is debating the fact that your home has zero equity. But you do need to think a step further - if you buy a new home you will need to come up with a down payment, closing costs, insurance, inspection and attny's fees. Or you can stay in a home that has little to no equity without shelling out thousands to get started again in a new home.
Your attny needs to be looking at the "now" and the future. Forget the equity as that is a moot point. Basically your H gets to stay in a home (and what happens when the market turns around or he gets a raise and can get the home out of the negative) with *some* possibility. You on the other hand get nothing EXCEPT the knowledge that you will have to save for a long time to even get in a home.
He gets the house - you get money. Period. Do NOT use any other item (car, support) to negotiate about the house.
