With regards to selling the property, I would aggresively address the price and continue addressing the price until the property is sold.

I would suggest you have your realtor drop the price and work through a short sale. Your realtor will know how to negotiate this with the lender that the property is vacant, etc. Drop the price aggressively to get a good offer to stick and hopefully you can sell to that buyer. Good luck!
