Feedback is always important to home sellers. They want to know what buyers think about their home. Is it priced right? Does it look nice? When I represent sellers I set them up so they get feedback from showings e-mailed directly to them as soon as it becomes available, and then I follow up once a week with a phone call to let them know what is going on in the local market and to discuss the showing feedback from that week.
Sellers want to know what I am doing and everything about the listing. Some agents give feedback and others don't.
