Good luck! I hope you can find a solution. I've been watching this show, How To Live Mortgage Free, and it's amazing to see how sometimes there IS a creative solution, but it might be so far out of the box that people don't see it at first. Have you thought about talking to an architect (if you know one)? It's their job to find solutions in these cases. I'd recommend the show in any case--maybe you could find an answer there. :)
