Just tell your agent you would like the information about your home to be kept confidential. There is going to be access to this information via public channels anyway (MLS and Title Records) but at least you can slow down the verbal gossip this way.... more
You are the client and I is not what the Realtor wants but what you the buyer wants. Realtor should supply all similar sold homes in area within last 6 months. These comparables should be within 0.50 miles from home but no more that 1 mile from subject. Hopefully, there will be a range of homes(fixers, original condition, updated). Make a realistic decision based on stats not emotion or hear-say.
