Huh? If you have been through a short sale do you mean the short sale went through and the seller sold the property? Well, than they would have nothing to refinance and would not qualify.
However, if the seller attempted to short sale and failed and is still living in the property refinancing would depend on the sellers credit, income, and the Loan to Value of the house.
Ah, but I just thought of a 3rd scenario I do know of a person that had two places. The owner did short sale one property and maintained the second. I would advice a person in this scenario to speak with a mortgage professional to access their situation.
