I don’t think you are going to get a counter when there are multiple offers on an REO. They may come back to you in a couple of weeks if they choose another buyer who fails to perform.
The most important thing you can do is make it obvious that you can perform. You want to submit prequal info with the offer. You are a little weak because of the borderline DP as you may not be able to perform if it doesn’t appraise.
