I attended 2 viewings and on both occasions the agents were late. Although one was quite up to speed on the details of the house the other agent had no idea what he was doing. He simply let us in the house and stood there in silence. He could not answer any questions and spoke in a very informal manner using terms such as 'mate' (despite this being our first meet).
The both of them seemed very pushy on viewings, trying to get us to look at properties we made clear did not fit any of our requirements. I understand they are on commission but it puts me off dealing with people that don't listen to anything you have told them!
