Here are three reasons for that to happen:
1. Many of the houses are actually in "pre-foreclosure" status. Therefore, they are not actual bank-owned and they are not officially on the market
2. Many REO or Bank owned properties are in very poor interior condition, AKA TRASHED. They wouldn't look attractive to buyers
3. Some agents who get these listings are very complascent. They have relationships with banks and get the listings automatically, so they don't have to work very hard to earn business.
I hope that this has helped you. If you have any other questions, just contact me.
