Is the home in the SF city/county limits? If so, and with our current market conditions being where they are, have you done the research using recent comps, etc to figure your estimated sales price first? A lot of people that would have been upside down just over a year ago are able to walk away breaking even or with a profit these days. Obviously, each persons' case is different but if you need help coming up with some projections I'm happy to help with no strings attached.
All the best and have a happy and healthy 2014!
