Though you are negotiating terms with the lender, they do not own the home. The lender doesnt have it listed. The lender owes you nothing.
Many buyers think they will be getting a great deal on a short sale. Not true (always a few exceptions) you are just buying a house at its full current value. Doesnt matter if it used to be worth $500,000 and you are getting it for $100,000. $100,000 is what it is NOW worth. Man y lebnders/laon servicers do not want to take short sale offers no2w. They would rather fully foreclose. Why? Thats an entire hours worth of discussion. Point is our government is printing billions and floating the banking system so they dont have to worry about taking back properties. For which party did you vote?
If you are truly interested in purchasing a short sale, do your research, make sure you're prepared to do any work that needs to be done (the sellers rarely do repairs), and have some patience and a good agent.
Let me know if I can be of any further help.
Best of luck!
