short sale but Vacant?

[Jason Green]

I know nothing about short sales but that is the only opportunity out there right now. The banks dont have their hearts right on REO's in my area and I build houses so why would I want a foreclosure at a courthouse sale at market price when I can build as many as I want for less than market price. Now, to my question, there are alot of houses foreclosing, when I see the legal ads, I drive to the property and it is already abandoned. Is it possible to negotiate a short sale if there are no owners (owners in terms of physical location). Thanks for the help.
