I used to be an agent. I don't think a lot of sellers have been told, or are willing to accept, that houses are a little like cars. That is, they must compare to the other make/models that are in the same price range. When a buyers agent is taking a client around to look at homes. They were chosen by the agent based on location, need and price considerations. If this house is actually WORTH what they are asking, fine. But I suspect that as agents show buyers around, they will compare it to the others in the price range and just laugh at this one.
My father and I had this experience in 1970 when I was looking for a car to drive to high school. A local dealership wanted $1,000 for a seven year old Nova that was repainted WITH A BRUSH and very high miles. This is 1970 dollars. I found a comparable car for $325, but my dad talked him down to $310.
Frankly, if a house is TOO high priced, agents will sometimes show it to make the others look like great deals. The carpet gets worn out for nothin'.
