Roberto, this depends on your particular situation. If you stopped making payments while you short sold your house, you wouldn't be eligible for an FHA mortgage for 3 full years from the date of the the short sale. For a conventional loan you'd be limited to an 80% LTV, 2 years after the short sale date, 90% LTV 4 years after the short sale date. After 7 years, you're free from restrictions.
If you paid your mortgage within the month of each payment due date, throughout the last 12 months from the short sale date, you may be eligible for an FHA loan if you were also on time with any other installment loans you owe. I am NOT aware of any sort of program that'll allow you to finance within 1 1/2 - 2 years from the short sale date.
