E, The asking price is not the value. Your offer should be based on what a good Comparative Market Analyisis detirmines the value to be. The value may be higher or lower, but there is no set guide on where agents, banks or homeowners set a list price.
If you are not working with your own Realtor, get one. We have the tools to do detailed research and come up with a good plan. If you are using the banks agent, they are contractually obligated to look out for the banks interest, not yours. You need your own representation, just like in court.
