It really depends on what you want. Would you like to see money from the sale of your home in the future? If so, ride out the market and then sale. Or if you feel the neighborhood that your home is in may decline in the future, maybe you should consider selling now and wash your hands of it. If you truly need funds now for the move, then go for it, try selling now. I see many people taking advantage of the decline in home prices for investment purposes or first time home buyers. If you also need help with relocation assistance, my company has a relocation department.
Hope this info can give you a little insight on your delimma.
