Here is a perfect example I ran across today.
4931 Nottingham in Riverside just listed at $660k. The home is a 5 bedroom 3 bath one story ranch, 3281 sq/ft on just under 1/2 acre. The realtor says this "Tired of making Offers on Bank owned homes or Short Sales with little or no reply? Our Seller will responds to all reasonable offers within 72 hrs of receipt".

Ok, what would be a reasonable offer? How about we go by the last comparable sale. Fortunately there is an exact model match in the same tract that sold only a month ago. 10084 Willowbrook is the same floorplan as the Nottingham house. It sold in late May for $441k. That comp is already a month old and the current prices are dropping at about 12k per month so a reasonable price for the Nottingham home is $429K.
That is $230K less that the asking price. I wonder if they'd consider that a reasonable offer? In reality though, it is a reasonable offer based on the last comparable sale. So again I ask "what is the point of even listing a home like this?" Any Realtors out there care to chime in on why other Realtors are still taking these crazy listings?
