Read about halfway through the thread and I think you are screwed. It’s one of those damned if you do damned if you don’t things. If you keep the condo you won’t be able to afford it, ever hear of child support?, if you lose it in foreclosure you lose your down payment. So you are in the same boat as many people that bought around 2005, you’re boat is just sinking a little faster. If you think the inlaws will give in, in the interest of the child, then you can try that tactic. Otherwise stop paying everyone and wait until the eviction. Believe it or not you can rent cheaper than your mortgage would be on the condo.
