You can take the free trial on RealtyTrac and cancel before the free trial period ends. You can also have a real estate agent that specializes in short sales help you find them. Lastly I suggest you Google "short sales Brooklyn" or any other search term you think may help., You will be surprised with the amount of information you can get by doing that.
Why is it that you are looking for a short sale? If the answer is because you believe you can get a better deal, then maybe what you really need is simply a good deal. If that is the case there are many ways to find them besides short sales. You are really looking for a motivated seller!
If I can be of further assistance, please let me know. Good luck!
