There are still some sellers out there that need or demand more than their home is actually worth in todays market. Those homes will not transfer to new ownership till that seller becomes realistic. But, with the right buyers representative you will know where to start and where to walk away as a sales price.

An average price for a home just provides an estimate to base a buying decision on. If you work with a local Realtor they will be able to show you comparable homes based on their experience of walking through these homes and knowing that they are fair comps.
Good Luck with your search
