I talked to a FSBO (for sale by owner) the other day and he was so frustrated. He had an open house and people came thru and criticized everything. They asked if the carpet was original, who choose THAT wallpaper, etc. It really hurt his feelings and made him mad. I explained that was one reason to use a real estate agent, we can stay impersonal. We didn't raise our kids there, and have no emotions toward the property so we can see the property for what it is and judge it's value accordingly.
