Jim i saw your other post as well about having the new home you need to sell quickly. I work with banks everyday on situations such as yours, if you need some help with a short sale to get out of the home, please get ahold of me. Either call or email me at email@example.com , i would love the opportunity to be able to help.
Kind of hard to tell what you are asking... But if you are a builder/developer I would suggest your question should be a link to a blog which holds the answers to your question...nice way to pontificate.
