Can you assign short sales

If you cant assign SS, can you do a double closing? Can I just get the homeowner under contract and submitted a SS, line up my cash buyer and do a SS.

Unfortunately, you cannot legally assign a short sale but if you are creative you can pass the deal to another investor an collect a nice fee. I do it all of the time because I am not interested in every deal that I find but I have other investors who are so I implement this system very often.
