This New York Times article discusses the phenomenon of potential buyers bringing friends or relatives back for help with second showings.

Then there is this question, often deployed after an offer has been accepted: “Do you mind if I bring my (decorator/mother/friend/boss/feng shui expert/rabbi) to take a look?”Yes, your broker minds. A lot. “It’s the kiss of death,” said Michele Conte, the sales director at the Centurion, a 48-unit condominium at 33 West 56th Street. “Brokers fear second opinions because, human beings being what they are, people always want to justify why someone asked them to come in. So the first thing they do is look for something wrong. And they also tend to judge by their own standards. One man’s meat is another man’s poison in real estate, big time.”

With regard to Maui real estate, we believe this is nonsense. Properties here tend to become more attractive upon repeated showings, especially if your agent is skilled at presenting the property to advantage. More often that not, in our experience, the friend too gets wowed by the property and confirms the initial buyers' judgement. If you are a buyer, don't be shy about asking for repeat showings and if you are a seller don't fear them. If a buyer is spooked by something, they will find a way to try to get out of a deal anyway. The trick is to have a skilled agent presenting your property.
