I've seen banks dump prices by as much as 40% in a single reduction, but it's typically on properties that were overpriced to start. Prices will continue to drop this year, anyone that thinks otherwise is going to be sadly mistaken. Rates are low, and look like they will continue to remain low for the next few months. Of course without the crystal ball, nobody is certain what's going to happen
Trying, you're very right, never lose sight of the fact that the banks ARE trying to recoup as much $$$ as possible! If it doesn't cost you any money, why NOT have an agent repping you?
My duty as a realtor is to protect my CLIENTS interest, be that a bank or an individual. If you're looking at a property I've listed, I can assure you my legal and fiduciary duty is to the seller. If I'm not the listing agent, then I'm probably working for the buyer, and that means I'm going to find all the angles to get the price dropped.
As a side note, someone had asked about dealing directly with the bank rather than realtors. The banks are assuming thousands of new assets each week nationwide. They don't have the time or manpower to deal with direct inquiries. I actually had a buyer try that on a bank owned listing of mine. The buyer managed to contact the asset manager, who told them to call their agent, and promptly hung up on them.
