It's really hard to say. Our short sale is with Met.
It took us 4 weeks to hear anything after hte BPO was completed. Infact, they got back to us on the DAY that hte contact expired (we gave them 45 days). Then we had to extend another 30 days for the 2nd mortgage to be approved( not sure if you have this issue or not)
Maybe your agent has heard something from the listing agent who heard from the negoitator.
We are currently waiting for approval on the 2nd mortgage on the home-- and our realtor told us it's not realistic that we will hear this week or next due to the holiday. Our contract expires on 1/4/13.
