Hey Gunny... wish I could tell you how that would work out. I know my W and I discussed similar arrangements just the other night. I outlined how our house is financed (which she knew going in but wanted to remind her).
She either will have to a) do nothing and when interest rates eventually go up face foreclosure, b) sell the house (not really a viable option right now), or c) re-fi the house while we're married. This puts my name on the mortgage (she bought the house and re-fi'd before we married).
Talk about no good options. I can't say I'm excited about staying in a financial arrangement with my W if it comes to us splitting. She had no problems hurting me this badly... why would she think twice about financially harming me? At least that's what the dark side of me thinks. I'm only considering the options because I don't want the kids uprooted if it comes to that.
If it can cashflow like the realtors think I'd suggest one party buy out the other and keep it clean. Or if you don't want her to get undue enrichment you could always sell and as part of the deal claim some part of the income for "x" period of time.
