Cad, did you buy your house talking directly to the asset manager at the bank that owned your house? Unless you say otherwise I"m going to guess no. I"ve worked at both B of A and Wells Fargo and still have friends working there, they can"t even talk to the asset managers so unless you have to oddball chance in hell that the REO in question is owned by some rinky dink bank that you can just call into and ask for the person running the show on the property in question then what your saying in regards to cutting out the listing agent is just nonsense.
A person doing their homework on the homes for sale in the area, taxes, hoa dues, mello roos, etc is just taken for granted. A good agent though will see houses (broker open) before they are on the MLS and will be able to let you know what is going on with the offers on a property due to their relationship with said listing agent. That"s why they get their money, if you don"t have an agent like that then I suggest that"s where you start.
