To offer you feedback based on your information would be pure "guess work." Generally banks have their properties priced pretty much where they want the offers to be.
You should take into consideration how long the property has been on the market and if there is interest from other buyers such as yourself. If a property has been on the market for a while the lender may be willing to accept lower offers but on the other hand if it is a desirable home, it's been on the market for only a short while, and you suspect other interest, you offer should be one that is higher than lower.....if you are serious about the property.
It may be time to form a relationship with a real estate professional, one that will be able to help you put together a plan that will help you be successful. With foreclosures and other things, "he who hesitates is lost."
Assuming, making a lower offer would be your best approach could be huge mistake....speak with a local agent!
