Went to a Home Open in Perth

Went to a home open the other day and it was quite interesting to see how different people inspect a home. Some seemed to be on the Amazing Race, stopping only for a moment in the middle of the house, before turning around and seemigly running off with a brochure. Others walked around the house, only to make a hasty exit as the real estate agent neared with requests for contact details. In the area that the house was, there were another 18 opens that afternoon. What does it take to present a house well in a home open? How much does it depend on the real estate agent and their approach? Would like to hear your thoughts
