Unless there was some sizable equity in it (and I had a reasonable legal claim to 1/2 of it under my state's family court laws), I would be inclined to accept his monthly contribution to you, but SKIP MAKING THE MORTGAGE PAYMENT, while beginning to seek suitable rental property in my desired area (like S7's school district). Even though NC is a non-judicial state for foreclosures, and they seem to be running 90-180 days (unlike Florida's 400+ days), you could sock away some needed funds doing that. And there are legal moves you could make to delay it even further.
I have been thinking long and hard about this decision. H just made the decision easier for me. I have NO choice now ...
