I am extremely late to the party on this question. I figured I would answer it so future people asking this similar question can find my answer.
My in house mortgage company has a program that will allow a previous Short Sale Borrower 1 day after Short Sale to purchase another home. The program requires 20% down payment and the borrower must have a 680 score and 2 year work history in same job.
Please feel free to reach out to me if I can be of any assistance.
