would be available if the sale is more than 3 years from the time you moved out.

I've looked all over and can't find anything anywhere (IRS website or otherwise) that states or even insinuates that.  The closest I can find is where AD/MIL can suspend the day count for the "2 of last 5" for a maximum of 10 years if they are moved on official orders.
